# BMI & BSA Calculator

## Overview

Clinical calculator for anthropometric measurements used in health assessment, obesity screening, and chemotherapy dosing calculations.

**Key Capabilities:**
- **BMI Calculation**: Standard and adjusted BMI formulas
- **BSA Estimation**: Multiple validated formulas (DuBois, Mosteller, Haycock)
- **Weight Classification**: WHO and CDC category assignment
- **Dosing Support**: Chemotherapy and medication dose calculations
- **Pediatric Support**: Age-appropriate norms and calculations
- **Unit Flexibility**: Metric and imperial input support

## When to Use

**✅ Use this skill when:**
- Calculating chemotherapy doses requiring BSA (mg/m²)
- Screening for obesity or underweight in clinical practice
- Adjusting drug doses based on body composition
- Documenting baseline anthropometrics in patient charts
- Teaching medical students clinical calculations
- Quick assessment in resource-limited settings

**❌ Do NOT use when:**
- BMI alone for clinical diagnosis → Use comprehensive metabolic assessment
- Pregnancy weight assessment → Use gestational weight gain charts
- Pediatric growth evaluation → Use WHO/CDC growth charts with percentiles
- Body composition analysis → Use DEXA or bioimpedance
- Athletic/muscular patients → Consider body fat % instead of BMI

**Integration:**
- **Upstream**: `ehr-semantic-compressor` (patient data extraction), `automated-soap-note-generator` (vital signs)
- **Downstream**: `drug-interaction-checker` (dose calculation), `medication-reconciliation` (dosing verification)

## Core Capabilities

### 1. BMI Calculation

Calculate Body Mass Index with classification:

```python
from scripts.calculator import BMIBSACalculator

calc = BMIBSACalculator()

# Calculate BMI
result = calc.calculate_bmi(
    weight_kg=70,
    height_cm=175,
    age=45,
    sex="male"
)

print(f"BMI: {result.bmi:.1f} kg/m²")
print(f"Category: {result.category}")  # Normal weight
print(f"Ideal weight range: {result.ideal_weight_range}")
```

**BMI Categories (WHO):**
| Category | BMI Range | Clinical Significance |
|----------|-----------|---------------------|
| **Underweight** | < 18.5 | Malnutrition risk |
| **Normal** | 18.5 - 24.9 | Healthy range |
| **Overweight** | 25.0 - 29.9 | Increased risk |
| **Obese I** | 30.0 - 34.9 | High risk |
| **Obese II** | 35.0 - 39.9 | Very high risk |
| **Obese III** | ≥ 40.0 | Extremely high risk |

**Adjusted BMI:**
- **BMI Prime**: BMI / 25 (obesity severity index)
- **Ponderal Index**: BMI for tall/short individuals
- **Age-adjusted**: For elderly patients (>65)

### 2. BSA Calculation

Multiple formulas for different clinical scenarios:

```python
# Calculate BSA using different formulas
bsa_results = calc.calculate_bsa(
    weight_kg=70,
    height_cm=175,
    formulas=["dubois", "mosteller", "haycock", "gehan_george"]
)

for formula, bsa in bsa_results.items():
    print(f"{formula}: {bsa:.2f} m²")
```

**BSA Formulas:**
| Formula | Equation | Best For |
|---------|----------|----------|
| **DuBois** | 0.007184 × W^0.425 × H^0.725 | Adults (most common) |
| **Mosteller** | √(W × H / 3600) | Adults (simplified) |
| **Haycock** | 0.024265 × W^0.5378 × H^0.3964 | Pediatrics |
| **Gehan-George** | 0.0235 × W^0.51456 × H^0.42246 | Oncology |
| **Yu** | 0.015925 × W^0.5 × H^0.5 | Asian populations |

### 3. Drug Dosing Calculations

Apply BSA to medication dosing:

```python
# Calculate chemotherapy dose
dose = calc.calculate_dose(
    bsa=bsa_results["dubois"],
    drug="carboplatin",
    dose_per_m2=400,  # mg/m²
    max_dose=800  # mg cap
)

print(f"Calculated dose: {dose:.0f} mg")
print(f"BSA used: {bsa_results['dubois']:.2f} m²")
```

**Common BSA-Based Doses:**
- Carboplatin: AUC-based (Calvert formula)
- 5-FU: 400-600 mg/m²
- Doxorubicin: 60-75 mg/m² (lifetime max 450-550 mg/m²)
- Paclitaxel: 135-175 mg/m²

### 4. Pediatric Calculations

Age-appropriate calculations for children:

```python
pediatric = calc.pediatric_mode(
    weight_kg=25,
    height_cm=120,
    age_years=8,
    sex="female"
)

print(f"BMI-for-age percentile: {pediatric.bmi_percentile}%")
print(f"Weight status: {pediatric.weight_status}")
print(f"BSA (Haycock): {pediatric.bsa:.2f} m²")
```

**Pediatric Considerations:**
- BMI percentiles (not absolute values)
- Growth chart integration
- Age-specific BSA formulas
- Body composition changes with development

## Common Patterns

### Pattern 1: Chemotherapy Dosing

**Scenario**: Calculate carboplatin dose for cancer patient.

```bash
# Calculate BSA and dose
python scripts/main.py \
  --weight 70 \
  --height 175 \
  --drug carboplatin \
  --target-auc 5 \
  --creatinine-clearance 80 \
  --output dose_calculation.txt
```

**Output:**
```
BSA (DuBois): 1.79 m²
Calvert Formula: Dose = Target AUC × (GFR + 25)
                 = 5 × (80 + 25)
                 = 525 mg
Maximum dose check: 525 mg ≤ 800 mg ✓
Recommended dose: 525 mg
```

### Pattern 2: Obesity Screening

**Scenario**: BMI assessment for weight management clinic.

```python
# BMI with full assessment
assessment = calc.assess_bmi(
    weight_kg=95,
    height_cm=165,
    age=52,
    sex="female",
    waist_cm=98
)

print(f"BMI: {assessment.bmi:.1f} (Obese Class II)")
print(f"Waist-to-height ratio: {assessment.whtr:.2f} (High risk)")
print(f"Comorbidity risk: {assessment.health_risk}")
print(f"Recommended: {assessment.recommendations}")
```

### Pattern 3: Pediatric Growth Assessment

**Scenario**: Calculate child's BSA for medication dosing.

```python
# Pediatric dosing
child = calc.pediatric_assessment(
    weight_kg=20,
    height_cm=110,
    age_years=6,
    sex="male"
)

print(f"BSA: {child.bsa:.2f} m² (Haycock formula)")
print(f"BMI percentile: {child.bmi_percentile}th")
print(f"Doxorubicin dose: {child.bsa * 60:.0f} mg")
```

### Pattern 4: Rapid Clinical Assessment

**Scenario**: Quick BMI/BSA for admission vital signs.

```bash
# Quick calculation
python scripts/main.py --weight 80 --height 180 --quick

# Output:
# BMI: 24.7 kg/m² (Normal)
# BSA: 2.00 m² (DuBois)
# Ideal weight: 65-80 kg
```

## Complete Workflow Example

**Comprehensive patient assessment:**

```python
from scripts.calculator import BMIBSACalculator
from scripts.reports import ClinicalReport

# Initialize
calc = BMIBSACalculator()
report = ClinicalReport()

# Patient data
patient = {
    "weight_kg": 75,
    "height_cm": 170,
    "age": 55,
    "sex": "female",
    "waist_cm": 88
}

# Calculate all metrics
bmi = calc.calculate_bmi(**patient)
bsa = calc.calculate_bsa(**patient, formula="dubois")
assessment = calc.comprehensive_assessment(**patient)

# Generate report
report_data = {
    "bmi": bmi,
    "bsa": bsa,
    "assessment": assessment,
    "recommendations": assessment.recommendations
}

report.generate(report_data, output="patient_assessment.pdf")
```

## Quality Checklist

**Input Validation:**
- [ ] Weight realistic (2-300 kg range)
- [ ] Height realistic (50-250 cm range)
- [ ] Units clearly specified (kg/lbs, cm/in)
- [ ] Age appropriate for formulas used

**Calculation Accuracy:**
- [ ] Formula selection appropriate for patient
- [ ] BSA formula matches clinical context
- [ ] Pediatric vs. adult norms correctly applied
- [ ] Rounding appropriate (1-2 decimal places)

**Clinical Interpretation:**
- [ ] **CRITICAL**: BMI is screening tool, not diagnostic
- [ ] Ethnicity-specific cutoffs considered
- [ ] Muscle mass considered (athletes)
- [ ] Age adjustments applied (elderly/children)

**Documentation:**
- [ ] Formula used documented (DuBois vs. Mosteller)
- [ ] Units clearly stated
- [ ] Date of calculation recorded
- [ ] Dose limits verified for chemotherapy

## Common Pitfalls

**Calculation Errors:**
- ❌ **Unit confusion** → Pounds vs. kg, inches vs. cm
  - ✅ Always verify units; convert if necessary

- ❌ **Wrong formula** → Using adult BSA for infants
  - ✅ Use Haycock for children < 12 years

- ❌ **BMI over-interpretation** → Diagnosing based on BMI alone
  - ✅ BMI is screening tool; clinical correlation required

**Clinical Misuse:**
- ❌ **Athletes misclassified** → Muscular patients marked obese
  - ✅ Consider waist circumference or body fat %

- ❌ **Elderly inappropriate norms** → Same cutoffs for all ages
  - ✅ Use age-adjusted BMI for >65 years

- ❌ **Ignoring ethnicity** → Universal cutoffs applied
  - ✅ Asian populations: lower obesity thresholds

**Dosing Errors:**
- ❌ **BSA rounding** → 1.79 m² rounded to 1.8 m²
  - ✅ Use precise values for chemotherapy

- ❌ **Max dose ignored** → Exceeding lifetime limits
  - ✅ Always check cumulative doses (doxorubicin)

# Automated SOAP Note Generator

## Overview

AI-powered clinical documentation tool that converts unstructured clinical input into professionally formatted SOAP notes compliant with medical documentation standards.

**Key Capabilities:**
- **Intelligent Parsing**: Extracts structured information from free-text clinical narratives
- **SOAP Classification**: Automatically categorizes content into Subjective, Objective, Assessment, Plan sections
- **Medical Entity Recognition**: Identifies symptoms, diagnoses, medications, procedures, and anatomical locations
- **Temporal Analysis**: Extracts timeline information (onset, duration, progression)
- **Template Generation**: Produces standardized SOAP format suitable for EHR integration
- **Multi-modal Input**: Accepts text dictation, transcripts, or clinical notes

## When to Use

**✅ Use this skill when:**
- Converting physician dictation into structured SOAP format for efficiency
- Processing audio-to-text transcripts from patient encounters
- Transforming consultation rough notes into formal documentation
- Generating initial draft documentation to reduce administrative burden
- Standardizing clinical encounter summaries for consistency
- Creating preliminary notes for routine follow-up visits

**❌ Do NOT use when:**
- Input contains PHI that hasn't been de-identified for testing/training
- Complex psychiatric cases requiring nuanced mental status documentation → Use specialized psychiatric documentation tools
- Surgical procedures requiring operative report detail → Use `operative-report-generator`
- Patient requires nuanced clinical reasoning beyond text extraction
- Legal or forensic documentation requiring exact transcription → Use verbatim transcription services
- Critical care situations requiring real-time precise documentation
- Cases requiring differential diagnosis prioritization without physician input

**⚠️ ALWAYS Required:**
- Physician review and approval before entering into patient record
- Verification of medical facts and clinical accuracy
- Confirmation of medication names, dosages, and instructions

## Integration with Other Skills

**Upstream Skills:**
- `medical-scribe-dictation`: Convert physician verbal dictation to text input
- `ehr-semantic-compressor`: Summarize lengthy EHR notes for SOAP generation
- `dicom-anonymizer`: Prepare imaging reports for SOAP inclusion
- `audio-script-writer`: Convert audio recordings to text format

**Downstream Skills:**
- `medical-email-polisher`: Professional communication of SOAP summaries to patients
- `clinical-data-cleaner`: Standardize extracted data for research databases
- `hipaa-compliance-auditor`: Verify de-identification before sharing documentation
- `discharge-summary-writer`: Generate discharge summaries from SOAP encounters
- `referral-letter-generator`: Create referral letters based on Assessment and Plan sections

**Complete Workflow:**
```
Medical Scribe Dictation (audio→text) → 
  Automated SOAP Note Generator (this skill) → 
    Physician Review → 
      EHR Entry / 
      Medical Email Polisher (patient communication) / 
      Referral Letter Generator (referrals)
```

## Core Capabilities

### 1. Input Processing and Preprocessing

Handle various input formats and prepare for NLP analysis:

```python
from scripts.soap_generator import SOAPNoteGenerator

generator = SOAPNoteGenerator()

# Process text input
soap_note = generator.generate(
    input_text="Patient presents with 2-day history of chest pain, radiating to left arm...",
    patient_id="P12345",
    encounter_date="2026-01-15",
    provider="Dr. Smith"
)

# Process from audio transcript
soap_note = generator.generate_from_transcript(
    transcript_path="consultation_transcript.txt",
    patient_id="P12345"
)
```

**Input Preprocessing Steps:**
1. **Text Cleaning**: Remove filler words ("um", "uh"), timestamps, speaker labels
2. **Sentence Segmentation**: Split into clinically meaningful segments
3. **Normalization**: Standardize abbreviations and medical shorthand
4. **Encoding Detection**: Handle various file formats (UTF-8, ASCII, etc.)

**Parameters:**
| Parameter | Type | Required | Description | Default |
|-----------|------|----------|-------------|---------|
| `input_text` | str | Yes* | Raw clinical text or dictation | None |
| `transcript_path` | str | Yes* | Path to transcript file | None |
| `patient_id` | str | No | Patient identifier (MUST be de-identified for testing) | None |
| `encounter_date` | str | No | Date in ISO 8601 format (YYYY-MM-DD) | Current date |
| `provider` | str | No | Healthcare provider name | None |
| `specialty` | str | No | Medical specialty context | "general" |
| `verbose` | bool | No | Include confidence scores | False |

*Either `input_text` or `transcript_path` required

**Best Practices:**
- Always verify input text quality (clear audio → better transcription → better SOAP)
- Remove patient identifiers before processing unless in secure environment
- Split long encounters (>30 minutes) into logical segments
- Flag ambiguous abbreviations for manual review

### 2. Medical Named Entity Recognition (NER)

Identify and extract medical concepts from unstructured text:

```python
# Extract entities with context
entities = generator.extract_medical_entities(
    "Patient has history of hypertension and diabetes, 
     currently taking lisinopril 10mg daily and metformin 500mg BID"
)

# Returns structured entities:
# {
#   "diagnoses": ["hypertension", "diabetes mellitus"],
#   "medications": [
#     {"name": "lisinopril", "dose": "10mg", "frequency": "daily"},
#     {"name": "metformin", "dose": "500mg", "frequency": "BID"}
#   ]
# }
```

**Entity Types Recognized:**
| Category | Examples | Notes |
|----------|----------|-------|
| **Diagnoses** | diabetes, hypertension, pneumonia | ICD-10 compatible where possible |
| **Symptoms** | chest pain, headache, nausea | Includes severity modifiers |
| **Medications** | metformin, lisinopril, aspirin | Extracts dose, route, frequency |
| **Procedures** | ECG, CT scan, blood draw | Includes body site |
| **Anatomy** | left arm, chest, abdomen | Laterality and location |
| **Lab Values** | glucose 120, BP 140/90 | Units and reference ranges |
| **Temporal** | yesterday, 3 days ago, chronic | Normalized to relative dates |

**Common Issues and Solutions:**

**Issue: Missed medications**
- Symptom: Generic names not recognized (e.g., "water pill" for diuretic)
- Solution: Manual review required; tool flags colloquial terms for verification

**Issue: Ambiguous abbreviations**
- Symptom: "SOB" could be shortness of breath or something else
- Solution: Context-aware disambiguation; flag uncertain cases

**Issue: Misspelled drug names**
- Symptom: "metfomin" instead of "metformin"
- Solution: Fuzzy matching with confidence threshold; flag low-confidence matches

### 3. SOAP Section Classification

Automatically categorize sentences into appropriate SOAP sections:

```python
# Classify content into SOAP sections
classified = generator.classify_soap_sections(
    "Patient reports chest pain for 2 days. Physical exam shows BP 140/90. 
     Likely angina. Schedule stress test and start aspirin 81mg daily."
)

# Output structure:
# {
#   "Subjective": ["Patient reports chest pain for 2 days"],
#   "Objective": ["Physical exam shows BP 140/90"],
#   "Assessment": ["Likely angina"],
#   "Plan": ["Schedule stress test", "start aspirin 81mg daily"]
# }
```

**Classification Rules:**
| Section | Content Type | Examples |
|---------|--------------|----------|
| **S** - Subjective | Patient-reported information | "Patient states...", "Patient reports...", "Complains of..." |
| **O** - Objective | Observable/measurable findings | Vital signs, physical exam, lab results, imaging |
| **A** - Assessment | Clinical interpretation | Diagnosis, differential, clinical impression |
| **P** - Plan | Actions to be taken | Medications, procedures, follow-up, patient education |

**Multi-label Handling:**
Some sentences span multiple sections (e.g., "Patient reports chest pain [S], which was sharp and 8/10 [S], with ECG showing ST elevation [O]")
- Tool splits compound sentences at conjunctions
- Assigns primary and secondary labels with confidence scores

**Best Practices:**
- Review classification accuracy, especially for complex multi-part statements
- Manually verify Assessment section (most critical for patient care)
- Ensure temporal context preserved (recent vs. chronic symptoms)

### 4. Temporal Information Extraction

Parse and normalize timeline information:

```python
# Extract temporal relationships
timeline = generator.extract_temporal_info(
    "Patient had chest pain starting 3 days ago, worsening since yesterday. 
     Had similar episode 2 months ago that resolved with rest."
)

# Returns:
# {
#   "onset": "3 days ago",
#   "progression": "worsening",
#   "previous_episodes": [
#     {"time": "2 months ago", "resolution": "with rest"}
#   ]
# }
```

**Temporal Elements Extracted:**
- **Onset**: When symptoms started ("2 days ago", "this morning")
- **Duration**: How long symptoms lasted ("for 3 hours", "ongoing")
- **Frequency**: How often symptoms occur ("daily", "intermittently")
- **Progression**: Getting better/worse/stable
- **Prior Episodes**: Previous similar events
- **Context**: "before meals", "with exertion", "at night"

**Normalization:**
Converts relative dates to standardized format:
- "yesterday" → Encounter date minus 1 day
- "3 days ago" → Specific date calculated
- "chronic" → Flagged for chronic condition tracking

### 5. Negation and Uncertainty Detection

Critical for accurate medical documentation:

```python
# Detect negations and uncertainties
analysis = generator.analyze_certainty(
    "Patient denies chest pain. No shortness of breath. 
     Possibly had fever yesterday but not sure."
)

# Identifies:
# - "denies chest pain" → Negative finding (important!)
# - "No shortness of breath" → Negative finding
# - "Possibly had fever" → Uncertain finding (flag for verification)
```

**Detection Categories:**
| Type | Cues | Action |
|------|------|--------|
| **Negation** | denies, no, without, absent | Mark as negative finding |
| **Uncertainty** | possibly, maybe, uncertain, ? | Flag for physician review |
| **Hypothetical** | if, would, could | Note as conditional |
| **Family History** | family history of, mother had | Separate from patient findings |

**⚠️ Critical:**
Negation errors are high-risk (e.g., missing "denies" → documenting symptom they don't have)
- Always verify negative findings in Subjective section
- Uncertain findings must be explicitly marked for review

### 6. Structured SOAP Generation

Produce final formatted output:

```python
# Generate complete SOAP note
soap_output = generator.generate_soap_document(
    structured_data=classified,
    format="markdown",  # Options: markdown, json, hl7, text
    include_metadata=True
)
```

**Output Format:**
```markdown

## Common Pitfalls

**Input Quality Issues:**
- ❌ **Poor audio quality** (background noise, mumbling) → Garbled transcription → Inaccurate SOAP
  - ✅ Ensure quiet environment for dictation; use high-quality microphone
  
- ❌ **Incomplete dictation** (provider trails off, changes subject) → Missing information
  - ✅ Dictate in complete sentences; pause between distinct thoughts

- ❌ **Heavy accents or fast speech** → Transcription errors
  - ✅ Speak clearly; review transcription immediately if possible

**Medical Accuracy Issues:**
- ❌ **Medication name confusion** ("Lipitor" vs "lipid lowerer") → Wrong drug documented
  - ✅ Always verify medication names; use generic names when possible

- ❌ **Missed negations** ("denies chest pain" → "has chest pain") → Critical error
  - ✅ Carefully review Subjective section for negative findings

- ❌ **Temporal confusion** ("pain since yesterday" vs "pain until yesterday") → Wrong timeline
  - ✅ Verify onset, duration, and progression with patient

- ❌ **Uncertain findings documented as certain** ("possibly pneumonia" → "pneumonia")
  - ✅ Flag all uncertain language for clarification

**Documentation Issues:**
- ❌ **Hallucinated information** (AI adds details not in input) → False documentation
  - ✅ Compare output directly with source material
  
- ❌ **Missing context** ("continue meds" without specifying which ones)
  - ✅ Ensure plan is specific and actionable

- ❌ **Generic assessments** ("patient is stable" without specifics)
  - ✅ Add clinical reasoning to Assessment section

**Compliance Issues:**
- ❌ **Entering AI-generated text without review** → Legal/medical liability
  - ✅ NEVER enter into patient record without physician approval
  
- ❌ **Including PHI in unsecured processing** → HIPAA violation
  - ✅ Use only in HIPAA-compliant environments

**Process Issues:**
- ❌ **Not saving original input** → Cannot verify if questions arise
  - ✅ Retain original dictation/transcript
  
- ❌ **No audit trail** → Cannot track AI involvement
  - ✅ Document that SOAP was AI-assisted in metadata

## Troubleshooting

**Problem: Poor entity recognition**
- Symptoms: Medications or diagnoses not detected
- Causes: Specialized terminology, misspellings, rare conditions
- Solutions:
  - Use generic drug names when possible
  - Check `references/medical_terminology.md` for supported terms
  - Manually add missing entities during review

**Problem: Wrong SOAP classification**
- Symptoms: Physical exam findings in Subjective; symptoms in Objective
- Causes: Ambiguous phrasing ("Patient appears in pain")
- Solutions:
  - Rephrase input for clarity ("Patient reports pain level 8/10")
  - Manually move sentences to correct sections
  - Check classification confidence scores

**Problem: Missing temporal information**
- Symptoms: All events seem to happen "now"
- Causes: Unclear time references ("recently", "a while ago")
- Solutions:
  - Use specific dates or durations in dictation
  - Manually add timeline during review
  - Ask patient for clarification on timing

**Problem: Inappropriate certainty level**
- Symptoms: "Possibly" removed; "definitely" added
- Causes: AI over-confident in uncertain situations
- Solutions:
  - Preserve physician's uncertainty language
  - Add qualifiers back during review
  - Flag all diagnostic statements for verification

**Problem: Formatting errors in output**
- Symptoms: Garbled text, wrong encoding, missing sections
- Causes: Special characters, non-ASCII text, file encoding issues
- Solutions:
  - Save input as UTF-8
  - Avoid special symbols in medication names
  - Check output file encoding

**Problem: Processing fails or hangs**
- Symptoms: Script crashes, timeout errors
- Causes: Very long input (>5000 words), complex nested clauses
- Solutions:
  - Split very long encounters into sections
  - Simplify complex sentences
  - Increase timeout limit for large inputs

# Audio Script Writer

## Overview

Content transformation tool that converts written medical and scientific materials into professionally structured audio scripts suitable for podcasts, educational videos, audiobooks, and voiceover narration.

**Key Capabilities:**
- **Format Conversion**: Research papers → podcast scripts
- **Spoken Word Optimization**: Sentence restructuring for listening
- **Pronunciation Guides**: Medical terminology phonetic spelling
- **Timing Estimation**: Duration calculations for production planning
- **Multi-Format Output**: Podcast, video, lecture, audiobook templates
- **Voice Direction**: Tone, pace, and emphasis cues for narrators

## When to Use

**✅ Use this skill when:**
- Creating medical education podcasts from journal articles
- Converting conference presentations to video scripts
- Developing audiobook versions of medical textbooks
- Scripting patient education audio materials
- Producing research summary videos for social media
- Adapting written case reports for audio case studies
- Creating voiceover scripts for e-learning modules

**❌ Do NOT use when:**
- Live presentation without script → Use improvisation
- Highly visual content (surgery videos) → Use visual-focused tools
- Interactive audio (Q&A format) → Use dialogue scripting tools
- Music or sound design planning → Use audio production software
- Voice recording itself → This creates scripts, not audio

**Integration:**
- **Upstream**: `abstract-summarizer` (content condensation), `lay-summary-gen` (patient-friendly language)
- **Downstream**: `medical-translation` (multi-language scripts), `voice-cloning-tool` (AI narration)

## Core Capabilities

### 1. Spoken Word Transformation

Convert written text to conversational audio style:

```python
from scripts.audio_writer import AudioScriptWriter

writer = AudioScriptWriter()

# Transform written content
script = writer.convert_to_audio(
    source_text=research_paper,
    format="podcast",  # podcast, video, lecture, audiobook
    target_audience="medical_students",
    duration_minutes=15
)

print(script.spoken_text)
# Converts: "The pathophysiology of diabetes mellitus involves..."
# To: "So what exactly happens in diabetes? Well, it all starts when..."
```

**Transformation Rules:**
| Written Style | Audio Style | Example |
|---------------|-------------|---------|
| "Furthermore" | "Plus" | Less formal transitions |
| " et al." | "and their colleagues" | Expand abbreviations |
| Numbers in text | Spoken numbers | "15%" → "15 percent" |
| Long sentences | 15-20 word max | Break into digestible chunks |
| Passive voice | Active voice | "was observed" → "we saw" |
| Citations | Omit or footnote | "(Smith et al., 2024)" → [reference tone] |

### 2. Pronunciation Guide Generation

Create phonetic spelling for medical terms:

```python
# Generate pronunciation guide
pronunciation = writer.create_pronunciation_guide(
    text=script,
    include_phonetic=True,
    include_syllables=True
)

# Output:
# "Hyperlipidemia: hi-per-lip-i-DEE-mee-uh"
# "Metformin: met-FOR-min"
# "Atherosclerosis: ath-er-oh-skleh-ROH-sis"
```

**Guide Elements:**
- **Phonetic Spelling**: IPA or simplified phonetics
- **Syllable Breaks**: hy-per-ten-sion
- **Emphasis Marking**: Primary stress (CAPS), secondary stress
- **Alternative Pronunciations**: Regional variations (UK vs US)
- **Sound-Alikes**: "rhymes with..." for difficult terms

### 3. Timing and Pacing

Calculate speaking duration and mark pacing cues:

```python
# Analyze timing
timing = writer.calculate_timing(
    script=script,
    speaking_rate="conversational",  # slow, conversational, fast
    include_pauses=True
)

print(f"Estimated duration: {timing.duration_minutes} minutes")
print(f"Word count: {timing.word_count}")
print(f"Pace: {timing.words_per_minute} WPM")
```

**Speaking Rates:**
| Style | WPM | Use Case |
|-------|-----|----------|
| **Slow/Educational** | 120-130 | Patient education, complex topics |
| **Conversational** | 140-160 | Podcasts, general audience |
| **Fast/News** | 170-190 | Time-constrained content |
| **Variable** | Varies | Dynamic pacing with pauses |

**Pacing Cues:**
```
[BREATHE] - Brief pause for narrator
[PAUSE 2s] - Two-second pause for emphasis
[SLOW DOWN] - Reduce pace for key point
[SPEED UP] - Increase energy/excitement
[BEAT] - Dramatic pause
```

### 4. Multi-Format Templates

Generate scripts for different audio formats:

```python
# Podcast episode
podcast = writer.create_podcast_script(
    content=article,
    episode_format="interview",  # solo, interview, panel
    include_intro_music=True,
    ad_breaks=[5, 12]  # minutes
)

# Educational video
video = writer.create_video_script(
    content=lecture_slides,
    visual_cues=True,  # Mark where visuals change
    b_roll_notes=True  # Suggest supplemental footage
)
```

**Format Types:**
| Format | Characteristics | Best For |
|--------|-----------------|----------|
| **Podcast** | Conversational, segments, ads | Long-form content, interviews |
| **Video** | Visual cues, B-roll notes | YouTube, educational platforms |
| **Lecture** | Structured, Q&A breaks | Online courses, training |
| **Audiobook** | Chapter markers, consistent tone | Textbooks, memoirs |
| **News** | Tight, factual, quick | Research briefs, updates |

## Common Patterns

### Pattern 1: Research Paper to Podcast

**Scenario**: Convert published study to 15-minute podcast episode.

```bash
# Convert paper to podcast script
python scripts/main.py \
  --input paper.pdf \
  --format podcast \
  --duration 15 \
  --style conversational \
  --include-intro-outro \
  --output podcast_script.txt

# Generate pronunciation guide
python scripts/main.py \
  --input podcast_script.txt \
  --generate-pronunciation \
  --output pronunciation_guide.txt
```

**Structure:**
```
[INTRO MUSIC 5s]

HOST: Welcome to Medical Research Today. I'm your host...

[BREATHE]

HOST: Today we're diving into a fascinating study about...

[PAUSE]

HOST: So what did the researchers find? Well...

[BREATHE]

HOST: Dr. Smith, one of the study authors, explains...

[SOUND BITE: Interview clip]

...

[OUTRO MUSIC]
```

### Pattern 2: Medical Lecture Recording

**Scenario**: Convert lecture notes to video script for online course.

```python
# Create lecture script
lecture = writer.create_lecture_script(
    notes=lecture_content,
    duration=45,  # minutes
    break_intervals=[15, 30],  # minutes for student breaks
    interaction_points=True  # "Pause and think..." prompts
)

# Add visual cues
script = writer.add_visual_cues(
    script=lecture,
    slide_transitions=True,
    animation_notes=True
)
```

**Lecture Elements:**
- Learning objectives at start
- Periodic comprehension checks
- Break reminders
- Transition phrases between topics
- Summary and key takeaways

### Pattern 3: Patient Education Audio

**Scenario**: Create audio guide for diabetes management.

```python
# Patient-friendly script
patient_script = writer.create_patient_script(
    medical_content=diabetes_guide,
    reading_level=6,  # 6th grade
    empathetic_tone=True,
    key_points_highlighted=True
)

# Slow, clear pacing
patient_script.adjust_pacing(
    wpm=130,
    pause_after_sentences=1.5  # seconds
)
```

**Patient Script Features:**
- Simple language (avoid medical jargon)
- Empathetic tone
- Clear action steps
- Reassuring statements
- Repetition of key points

### Pattern 4: Conference Presentation to Video

**Scenario**: Adapt live presentation to YouTube video format.

```bash
# Convert presentation script
python scripts/main.py \
  --input presentation_transcript.txt \
  --format video \
  --platform youtube \
  --include-hooks true \
  --engagement-cues true \
  --output youtube_script.txt
```

**YouTube Optimization:**
- Hook in first 30 seconds
- Engagement questions for comments
- Call to action (subscribe, like)
- Timestamp markers for chapters
- B-roll suggestions for visual interest

## Complete Workflow Example

**From research paper to published podcast:**

```bash
# Step 1: Extract and summarize content
python scripts/main.py \
  --input paper.pdf \
  --extract-key-points \
  --output key_points.txt

# Step 2: Convert to audio script
python scripts/main.py \
  --input key_points.txt \
  --format podcast \
  --duration 20 \
  --output raw_script.txt

# Step 3: Add production elements
python scripts/main.py \
  --input raw_script.txt \
  --add-music-cues \
  --add-sound-effects \
  --add-pacing-marks \
  --output production_script.txt

# Step 4: Generate pronunciation guide
python scripts/main.py \
  --input production_script.txt \
  --generate-pronunciation \
  --output pronunciations.txt

# Step 5: Create timing breakdown
python scripts/main.py \
  --input production_script.txt \
  --calculate-timing \
  --output timing_breakdown.txt
```

**Python API:**

```python
from scripts.audio_writer import AudioScriptWriter
from scripts.pronunciation import PronunciationGuide
from scripts.timing import TimingCalculator

# Initialize
writer = AudioScriptWriter()
pronouncer = PronunciationGuide()
timing = TimingCalculator()

# Read source material
with open("research_article.txt", "r") as f:
    content = f.read()

# Step 1: Convert to spoken format
script = writer.convert_to_audio(
    text=content,
    format="podcast",
    target_duration=15,  # minutes
    audience="general_medical"
)

# Step 2: Add production elements
script_with_cues = writer.add_production_cues(
    script=script,
    music_stings=True,
    transition_effects=True
)

# Step 3: Generate pronunciation guide
medical_terms = pronouncer.extract_terms(script_with_cues)
pronunciation_guide = pronouncer.create_guide(medical_terms)

# Step 4: Calculate timing
timing_analysis = timing.calculate(
    script=script_with_cues,
    speaking_rate=150  # WPM
)

# Export complete production package
writer.export_production_package(
    script=script_with_cues,
    pronunciation=pronunciation_guide,
    timing=timing_analysis,
    output_dir="podcast_production/"
)
```

## Quality Checklist

**Content Quality:**
- [ ] Written content accurate and current
- [ ] Sources cited (even if not spoken)
- [ ] Medical facts verified by expert
- [ ] Appropriate for target audience level
- [ ] No confidential patient information

**Audio Optimization:**
- [ ] Sentences 15-20 words maximum
- [ ] Abbreviations expanded on first use
- [ ] Complex terms have pronunciation guides
- [ ] Active voice preferred over passive
- [ ] Transitions smooth and conversational

**Production Quality:**
- [ ] Timing realistic for content density
- [ ] Pacing cues appropriate for subject
- [ ] Music/sound cues marked clearly
- [ ] Pronunciation guide comprehensive
- [ ] Script formatted for easy reading

**Before Recording:**
- [ ] **CRITICAL**: Script read aloud for flow
- [ ] Difficult pronunciations practiced
- [ ] Timing tested with stopwatch
- [ ] Technical terms confirmed with subject expert
- [ ] Copyright cleared for any quoted material

## Common Pitfalls

**Content Issues:**
- ❌ **Too dense** → Information overload for listeners
  - ✅ Break complex topics into multiple episodes

- ❌ **Visual dependencies** → "As shown in Figure 3..."
  - ✅ Describe visuals or omit visual-dependent content

- ❌ **Citation overload** → Every sentence has reference
  - ✅ Save citations for show notes, not narration

**Audio Issues:**
- ❌ **Written-style language** → "Furthermore, the aforementioned..."
  - ✅ Conversational: "Plus, this thing we talked about..."

- ❌ **No pauses** → Relentless information delivery
  - ✅ Build in breathing room; let points sink in

- ❌ **Ignoring pronunciation** → Mispronounced medical terms
  - ✅ Research and practice all technical terms

**Production Issues:**
- ❌ **Underestimating time** → 10 minutes of script takes 12+ to record
  - ✅ Add 20% buffer for retakes and natural pacing

- ❌ **Complex sentence structures** → Tongue twisters for narrator
  - ✅ Short sentences; avoid nested clauses

# Antibody Humanizer

## Overview

Bioinformatics platform for converting murine antibodies into humanized variants by grafting complementarity-determining regions (CDRs) onto human framework templates while preserving antigen-binding affinity and reducing immunogenicity risk.

**Key Capabilities:**
- **CDR Identification**: Automatic CDR boundary detection (Kabat/Chothia/IMGT schemes)
- **Framework Matching**: Database search for optimal human germline templates
- **Humanization Scoring**: Multi-parameter immunogenicity risk assessment
- **Back-Mutation Prediction**: Identify critical framework residues for retention
- **Batch Processing**: Humanize multiple antibody candidates efficiently
- **Immunogenicity Assessment**: T-cell epitope and humanness scoring

## When to Use

**✅ Use this skill when:**
- Converting murine hybridoma antibodies to therapeutic candidates
- Reducing immunogenicity risk of rodent-derived antibodies
- Selecting human framework templates for CDR grafting
- Identifying critical framework residues for antigen binding
- Comparing multiple humanization strategies for lead optimization
- Preparing antibody sequences for patent filings
- Teaching antibody engineering principles

**❌ Do NOT use when:**
- Fully human antibody generation from phage display → Use `phage-display-library`
- De novo antibody design → Use `antibody-design-ai`
- Affinity maturation → Use `affinity-maturation-predictor`
- ADCC/CDC optimization → Use `fc-engineering-toolkit`
- Final therapeutic candidate selection → Requires experimental validation

**Integration:**
- **Upstream**: `antibody-sequencer` (VH/VL sequence determination), `cdr-grafting-validator` (structural assessment)
- **Downstream**: `protein-struct-viz` (3D visualization), `immunogenicity-predictor` (T-cell epitope analysis)

## Core Capabilities

### 1. CDR Region Identification

Parse antibody sequences and identify CDR boundaries:

```python
from scripts.humanizer import AntibodyHumanizer

humanizer = AntibodyHumanizer()

# Analyze antibody sequence
analysis = humanizer.analyze_sequence(
    vh_sequence="QVQLQQSGPELVKPGASVKISCKASGYTFTDYYMHWVKQSHGKSLEWIGYINPSTGYTEYNQKFKDKATLTVDKSSSTAYMQLSSLTSEDSAVYYCAR...",
    vl_sequence="DIQMTQSPSSLSASVGDRVTITCRASQGISSWLAWYQQKPGKAPKLLIYKASSLESGVPSRFSGSGSGTDFTLTISSLQPEDFATYYCQQYSSYPYT...",
    scheme="chothia"  # Options: kabat, chothia, imgt
)

# Output CDR locations
print(analysis.cdr_regions)
# {
#   "VH_CDR1": {"start": 26, "end": 32, "seq": "GYTFTDY"},
#   "VH_CDR2": {"start": 52, "end": 58, "seq": "INPSTGY"},
#   ...
# }
```

**Numbering Schemes:**
| Scheme | VH CDR1 | VH CDR2 | VH CDR3 | Best For |
|--------|---------|---------|---------|----------|
| **Chothia** | 26-32 | 52-56 | 95-102 | Structural analysis |
| **Kabat** | 31-35 | 50-65 | 95-102 | Sequence-based work |
| **IMGT** | 27-38 | 56-65 | 105-117 | Standardized analysis |

### 2. Human Framework Matching

Identify optimal human germline templates:

```python
# Match against human germline database
matches = humanizer.find_human_frameworks(
    vh_framework=analysis.vh_frameworks,
    vl_framework=analysis.vl_frameworks,
    top_n=5,
    criteria=["homology", "canonical_structure", "vernier_similarity"]
)

# Evaluate each candidate
for match in matches:
    print(f"Template: {match.germline_genes}")
    print(f"Homology: {match.homology:.2%}")
    print(f"Vernier Score: {match.vernier_score:.1f}")
    print(f"Risk Level: {match.immunogenicity_risk}")
```

**Matching Criteria:**
- **Sequence Homology**: Percent identity to human germline
- **Canonical Structure**: Loop conformation compatibility
- **Vernier Region**: Framework residues contacting CDRs
- **Interface Residues**: Packing interactions with CDRs

### 3. Humanization Scoring

Assess immunogenicity risk of candidates:

```python
# Score humanization candidates
scores = humanizer.score_candidates(
    murine_antibody=analysis,
    human_templates=matches,
    scoring_methods=["t20", "h_score", "germline_deviation", "paratope_diversity"]
)

# Rank by overall score
ranked = scores.rank_by_composite_score(
    weights={"humanness": 0.4, "binding_retention": 0.4, "developability": 0.2}
)
```

**Scoring Methods:**
| Method | Description | Target |
|--------|-------------|--------|
| **T20 Score** | 20-mer peptide humanization | >80% human |
| **H-Score** | Hummerblind germline distance | <15 mutations |
| **Paratope Diversity** | CDR germline gene diversity | Low diversity |
| **Developability** | Aggregation/pH stability prediction | High score |

### 4. Back-Mutation Prediction

Identify critical residues to retain from murine framework:

```python
# Predict back-mutations
back_mutations = humanizer.predict_back_mutations(
    murine_vh=analysis.vh_sequence,
    human_vh=matches[0].human_template,
    cdr_regions=analysis.cdr_regions,
    rationale_required=True
)

# Output shows position-specific recommendations
for mutation in back_mutations:
    print(f"Position {mutation.position}: {mutation.human_aa} → {mutation.murine_aa}")
    print(f"Rationale: {mutation.reason}")  # e.g., "Vernier region contact"
    print(f"Priority: {mutation.priority}")  # Critical/Important/Optional
```

**Critical Residue Classes:**
- **Vernier Positions**: Framework residues contacting CDRs (VH 24, 71, 94)
- **Interface Packs**: Residue packing between VH and VL
- **Canonical Anchors**: Cysteines and conserved framework positions
- ** Buried Positions**: Core packing residues affecting stability

## Common Patterns

### Pattern 1: Standard Therapeutic Humanization

**Scenario**: Convert murine anti-tumor antibody to therapeutic candidate.

```bash
# Humanize single antibody
python scripts/main.py \
  --vh "QVQLQQSGPELVKPGASVKISCKAS..." \
  --vl "DIQMTQSPSSLSASVGDRVTITCRAS..." \
  --name "Anti-HER2-Murine-1" \
  --scheme chothia \
  --top-n 3 \
  --output humanization_report.json

# Review top candidates
cat humanization_report.json | jq '.candidates[0]'
```

**Workflow:**
1. Input murine VH/VL sequences
2. Identify CDRs using Chothia scheme
3. Match to human germline database
4. Score top 3 candidates
5. Identify required back-mutations
6. Output humanized sequences

### Pattern 2: Batch Humanization Screening

**Scenario**: Screen multiple murine clones from hybridoma campaign.

```python
# Process multiple antibodies
antibodies = [
    {"name": "Clone-A", "vh": "...", "vl": "..."},
    {"name": "Clone-B", "vh": "...", "vl": "..."},
    {"name": "Clone-C", "vh": "...", "vl": "..."}
]

results = humanizer.batch_humanize(
    antibodies=antibodies,
    ranking_criteria="composite_score",
    min_humanness=0.85
)

# Rank by developability
ranked = results.rank_by(criteria=["humanness", "binding_retention", "stability"])
```

**Selection Criteria:**
- Highest humanness score (>85%)
- Fewest back-mutations required (<6)
- Low immunogenicity risk
- Good developability profile

### Pattern 3: Framework Template Comparison

**Scenario**: Compare different humanization strategies for lead candidate.

```python
# Test multiple framework combinations
strategies = [
    {"vh": "IGHV1-2*02", "vl": "IGKV1-12*01", "name": "Template-A"},
    {"vh": "IGHV3-23*01", "vl": "IGKV3-20*01", "name": "Template-B"},
    {"vh": "IGHV4-34*01", "vl": "IGKV1-5*01", "name": "Template-C"}
]

comparison = humanizer.compare_strategies(
    murine_antibody=analysis,
    strategies=strategies,
    metrics=["homology", "back_mutations", "immunogenicity", "paratope_structure"]
)

comparison.generate_report("framework_comparison.pdf")
```

**Comparison Metrics:**
- Sequence identity to human germline
- Number and location of back-mutations
- Predicted immunogenicity risk
- CDR conformation preservation

### Pattern 4: Intellectual Property Analysis

**Scenario**: Assess humanization for patent landscape analysis.

```bash
# Generate humanized variants
python scripts/main.py \
  --input murine_lead.json \
  --generate-variants 10 \
  --include-back-mutations \
  --output variants_for_ip.json

# Check novelty against patent databases
python scripts/patent_check.py \
  --sequences variants_for_ip.json \
  --databases [USPTO, EPO, WIPO] \
  --output novelty_report.pdf
```

**IP Considerations:**
- Human framework combinations may be patented
- CDR sequences determine antigen specificity
- Back-mutation positions may be prior art
- Document humanization rationale for filings

## Complete Workflow Example

**From murine hybridoma to therapeutic candidate:**

```bash
# Step 1: Sequence analysis and CDR identification
python scripts/main.py \
  --vh $VH_SEQUENCE \
  --vl $VL_SEQUENCE \
  --scheme chothia \
  --output step1_analysis.json

# Step 2: Find best human frameworks
python scripts/main.py \
  --input step1_analysis.json \
  --find-frameworks \
  --top-n 5 \
  --output step2_frameworks.json

# Step 3: Score and rank candidates
python scripts/main.py \
  --input step2_frameworks.json \
  --score-candidates \
  --include-immunogenicity \
  --output step3_scored.json

# Step 4: Predict back-mutations
python scripts/main.py \
  --input step3_scored.json \
  --predict-back-mutations \
  --rationale \
  --output step4_backmutations.json

# Step 5: Generate final humanized sequences
python scripts/main.py \
  --input step4_backmutations.json \
  --generate-sequences \
  --format fasta \
  --output humanized_antibody.fasta
```

**Python API:**

```python
from scripts.humanizer import AntibodyHumanizer
from scripts.scoring import HumanizationScorer
from scripts.backmutation import BackMutationPredictor

# Initialize pipeline
humanizer = AntibodyHumanizer()
scorer = HumanizationScorer()
bm_predictor = BackMutationPredictor()

# Step 1: Parse and analyze
antibody = humanizer.analyze_sequence(
    vh_sequence=murine_vh,
    vl_sequence=murine_vl,
    scheme="chothia"
)

# Step 2: Find human frameworks
candidates = humanizer.find_human_frameworks(
    antibody,
    top_n=5
)

# Step 3: Score candidates
for candidate in candidates:
    scores = scorer.calculate_scores(
        murine=antibody,
        humanized=candidate
    )
    candidate.composite_score = scores.weighted_score()

# Step 4: Select best and predict back-mutations
best = max(candidates, key=lambda x: x.composite_score)
back_mutations = bm_predictor.predict(
    murine=antibody,
    human_template=best
)

# Step 5: Generate final sequence
final_sequence = humanizer.generate_humanized_sequence(
    template=best,
    back_mutations=back_mutations,
    cdrs=antibody.cdr_regions
)

print(f"Humanized antibody generated:")
print(f"- Humanness: {best.humanness:.1%}")
print(f"- Back-mutations: {len(back_mutations)}")
print(f"- Risk level: {best.immunogenicity_risk}")
```

## Quality Checklist

**Input Quality:**
- [ ] VH and VL sequences complete (110-130 aa typical)
- [ ] No ambiguous residues (B, Z, X)
- [ ] Signal peptide removed
- [ ] Constant region removed (variable region only)

**Humanization Assessment:**
- [ ] CDR boundaries correctly identified
- [ ] Human framework homology >80%
- [ ] T20 score >75 (high humanness)
- [ ] Vernier positions analyzed for back-mutations
- [ ] Interface residues checked for packing

**Output Validation:**
- [ ] Humanized sequence valid (no stop codons)
- [ ] CDRs preserved exactly
- [ ] Framework length conserved
- [ ] Back-mutations documented with rationale
- [ ] **CRITICAL**: Immunogenicity risk assessed

**Before Experimental Work:**
- [ ] **CRITICAL**: Top 2-3 candidates selected for expression
- [ ] Binding affinity to be tested (ELISA/Biacore)
- [ ] Stability assessed (thermal/aggregation)
- [ ] Immunogenicity in vitro assays planned

## Common Pitfalls

**Sequence Issues:**
- ❌ **Incomplete sequences** → Missing framework regions
  - ✅ Ensure full VH/VL variable domains provided
  
- ❌ **Wrong numbering scheme** → CDR boundaries incorrect
  - ✅ Verify scheme matches experimental data source

- ❌ **Non-standard residues** → Unusual amino acids
  - ✅ Clean sequences; remove signal peptides

**Design Issues:**
- ❌ **Over-humanization** → Losing antigen binding
  - ✅ Don't exceed 85-90% humanness; retain critical residues

- ❌ **Ignoring back-mutations** → Assuming 100% human framework works
  - ✅ Always predict and test back-mutations

- ❌ **Single candidate only** → No backup options
  - ✅ Generate 2-3 candidates with different frameworks

**Experimental Issues:**
- ❌ **Skipping binding validation** → Assuming in silico = in vivo
  - ✅ Always confirm antigen binding experimentally

- ❌ **Ignoring developability** → Aggregation or instability
  - ✅ Check for problematic residues (unpaired cysteines, hydrophobic patches)

# Anki Card Creator

## Overview

Intelligent flashcard generation tool that transforms medical study materials into Anki-compatible cards optimized for long-term retention through evidence-based spaced repetition.

**Key Capabilities:**
- **Multi-Format Input**: PDF textbooks, lecture slides, notes, web articles
- **Card Type Selection**: Basic, reversible, cloze deletion, image occlusion
- **Spaced Repetition Optimization**: Cards formatted for optimal review intervals
- **Automated Tagging**: Hierarchical organization by subject and topic
- **Media Integration**: Auto-download and embed relevant images
- **Batch Processing**: Convert entire chapters or courses efficiently

## When to Use

**✅ Use this skill when:**
- Preparing for medical board exams (USMLE, MCAT, specialty boards)
- Memorizing drug names, mechanisms, and side effects
- Learning anatomy structures and relationships
- Retaining biochemical pathways and reactions
- Creating pathology differential diagnosis cards
- Converting lecture notes to active recall format
- Building comprehensive review decks from textbooks

**❌ Do NOT use when:**
- Learning conceptual understanding → Use textbooks/videos first
- Memorizing without context → Ensure comprehension before card creation
- Creating cards for rapidly changing information → Use current resources
- Substituting clinical experience → Cards supplement, not replace practice
- Complex procedural skills → Use simulation or hands-on training

**Integration:**
- **Upstream**: `abstract-summarizer` (textbook chapter condensation), `pdf-text-extractor` (content extraction)
- **Downstream**: `anki-sync-server` (cloud backup), `study-schedule-optimizer` (review planning)

## Core Capabilities

### 1. Cloze Deletion Generation

Create fill-in-the-blank cards from dense text:

```python
from scripts.card_creator import AnkiCardCreator

creator = AnkiCardCreator()

# Generate cloze cards from text
text = """
Acute inflammation is characterized by five cardinal signs: 
redness (rubor), heat (calor), swelling (tumor), pain (dolor), 
and loss of function (functio laesa). These result from 
vasodilation, increased vascular permeability, and leukocyte 
infiltration.
"""

cards = creator.create_cloze_cards(
    text=text,
    n_cards=3,  # Generate 3 cards from this text
    difficulty="intermediate",
    tags=["Pathology", "Inflammation", "General_Pathology"]
)

# Output format (Anki-compatible)
# Card 1: "Acute inflammation is characterized by {{c1::five}} cardinal signs..."
# Card 2: "...signs: {{c1::redness}} (rubor), {{c2::heat}} (calor)..."
```

**Cloze Strategies:**
| Strategy | Use Case | Example |
|----------|----------|---------|
| **Single Deletion** | Key facts | "The {{c1::liver}} is the largest internal organ" |
| **Multiple Deletions** | Lists/groups | "CRAB symptoms: {{c1::Calcium}}, {{c2::Renal}}, {{c3::Anemia}}, {{c4::Bone}}" |
| **Hierarchical** | Progressive detail | "{{c1::Metformin}} is a {{c2::biguanide}} that {{c3::decreases hepatic glucose production}}" |

### 2. Basic and Reversible Cards

Generate question-answer pairs:

```python
# Create basic cards
cards = creator.create_basic_cards(
    content={
        "What is the mechanism of action of penicillin?": 
            "Inhibition of bacterial cell wall synthesis by binding to PBPs",
        "What are the major side effects of ACE inhibitors?":
            "Dry cough, hyperkalemia, angioedema, hypotension"
    },
    reversible=True,  # Create reverse cards too
    tags=["Pharmacology", "Antibiotics"]
)
```

**Card Types:**
- **Basic**: Question → Answer
- **Reversible**: Both directions (Q→A and A→Q)
- **Type-in**: Student types answer for active recall
- **Hint Cards**: Progressive disclosure with hints

### 3. Image Occlusion Cards

Create visual learning cards from diagrams:

```python
# Image occlusion for anatomy
cards = creator.create_image_occlusion(
    image_path="brachial_plexus.png",
    occlude_regions=[
        {"label": "Musculocutaneous nerve", "coords": (120, 200, 200, 240)},
        {"label": "Median nerve", "coords": (300, 250, 380, 290)},
        {"label": "Ulnar nerve", "coords": (400, 280, 480, 320)}
    ],
    card_type="one_by_one"  # or "all_at_once"
)
```

**Occlusion Types:**
- **One by One**: Reveal structures progressively
- **All at Once**: Identify all occluded regions
- **Transparent**: Hint visible through occlusion
- **Colored**: Different colors for different structures

### 4. Smart Tagging and Organization

Automatically organize cards into logical hierarchies:

```python
# Auto-tag based on content
cards = creator.process_textbook_chapter(
    chapter_text=pathoma_chapter,
    source="Pathoma - Hematopoiesis",
    auto_tag=True,
    tag_hierarchy=[
        "Pathoma",
        "{{chapter_name}}",
        "{{section_name}}"
    ]
)

# Results in tags like:
# Pathoma::Hematopoiesis::Red_Cell_Disorders
# Pathoma::Hematopoiesis::White_Cell_Disorders
```

**Tagging Strategies:**
- **Source-based**: First Aid, Pathoma, Sketchy
- **Subject-based**: Anatomy, Physiology, Pharmacology
- **Exam-based**: USMLE_Step1, Step2_CK, Shelf_Exams
- **Difficulty**: High_Yield, Medium_Yield, Low_Yield

## Common Patterns

### Pattern 1: Textbook Chapter Conversion

**Scenario**: Convert entire First Aid chapter to Anki deck.

```bash
# Extract and convert chapter
python scripts/main.py \
  --input first_aid_cardiology.pdf \
  --chapter "Ischemic Heart Disease" \
  --card-type cloze \
  --n-cards-per-page 3 \
  --tags "First_Aid::Cardiology::IHD" \
  --output ischemic_heart_disease.apkg

# Import directly to Anki
# File ready for import with media included
```

**Workflow:**
1. Read chapter for understanding first
2. Run conversion tool
3. Review generated cards for accuracy
4. Import to Anki
5. Study with standard spaced repetition

### Pattern 2: Drug Cards with Images

**Scenario**: Create comprehensive pharmacology cards.

```python
# Generate drug cards with mechanisms
drugs = [
    {
        "name": "Metformin",
        "class": "Biguanide",
        "mechanism": "Activates AMPK, decreases hepatic gluconeogenesis",
        "indications": "Type 2 diabetes, PCOS",
        "side_effects": "GI upset, lactic acidosis (rare), B12 deficiency",
        "image": "metformin_structure.png"
    }
]

cards = creator.create_drug_cards(
    drugs=drugs,
    include_structures=True,
    include_mechanism_diagrams=True,
    tags=["Pharmacology", "Diabetes", "First_Line"]
)
```

**Card Format:**
```
Front: Metformin - Class?
Back: Biguanide
Tags: Pharmacology::Diabetes::First_Line

Front: Metformin - Mechanism?
Back: Activates AMPK → decreases hepatic gluconeogenesis
Image: [mechanism diagram]
Tags: Pharmacology::Diabetes::Mechanism

Front: Metformin - Side effects?
Back: GI upset, lactic acidosis (rare), B12 deficiency
Tags: Pharmacology::Diabetes::Side_Effects
```

### Pattern 3: Pathology Differential Cards

**Scenario**: Create cards for differential diagnosis practice.

```python
# Differential diagnosis cards
cards = creator.create_differential_cards(
    condition="Cough with hemoptysis",
    differentials=[
        {"diagnosis": "Lung cancer", "key_features": "Smoker, weight loss, mass on CT"},
        {"diagnosis": "TB", "key_features": "Immigrant, night sweats, cavitary lesion"},
        {"diagnosis": "PE", "key_features": "Sudden onset, tachypnea, D-dimer elevated"},
        {"diagnosis": "Bronchiectasis", "key_features": "Chronic cough, purulent sputum, dilated airways"}
    ],
    card_type="compare_contrast"
)
```

**Card Types:**
- **Feature → Diagnosis**: "Smoker + hemoptysis + weight loss → ?"
- **Diagnosis → Features**: "Lung cancer presentation?"
- **Compare**: "Differentiate lung cancer vs TB"

### Pattern 4: Lecture Notes to Cards

**Scenario**: Convert professor's lecture slides to study cards.

```bash
# Process lecture PDF
python scripts/main.py \
  --input lecture_slides.pdf \
  --source "Dr_Smith_Cardiology_Lecture_5" \
  --card-type mixed \
  --extract-images \
  --auto-tag \
  --output cardiology_lecture_5.apkg

# Review and edit in Anki
# Delete low-yield cards
# Add personal mnemonics
```

**Post-Processing Tips:**
- Delete obvious or overly simple cards
- Merge redundant cards
- Add personal memory hooks
- Suspend low-yield topics

## Complete Workflow Example

**Building comprehensive USMLE Step 1 deck:**

```bash
# Step 1: Process multiple sources
python scripts/main.py \
  --input first_aid_pathology.pdf \
  --source "First_Aid_2024" \
  --card-type cloze \
  --tags "First_Aid::Pathology" \
  --output fa_pathology.apkg

python scripts/main.py \
  --input sketchy_pharm.pdf \
  --source "Sketchy_Pharm" \
  --card-type basic \
  --include-images \
  --tags "Sketchy::Pharm" \
  --output sketchy_pharm.apkg

# Step 2: Merge decks
python scripts/main.py \
  --merge fa_pathology.apkg sketchy_pharm.apkg \
  --output usmle_step1_master.apkg

# Step 3: Add leech tags for difficult cards
python scripts/main.py \
  --input usmle_step1_master.apkg \
  --tag-leeches \
  --leech-threshold 8 \
  --output usmle_step1_tagged.apkg
```

**Python API:**

```python
from scripts.card_creator import AnkiCardCreator
from scripts.importers import PDFImporter

# Initialize
creator = AnkiCardCreator()
importer = PDFImporter()

# Import and process textbook
content = importer.import_pdf(
    path="robbins_pathologic_basis_of_disease.pdf",
    pages="150-200",  # Inflammation chapter
    extract_images=True
)

# Create cloze cards
cards = creator.create_cloze_cards(
    text=content.text,
    images=content.images,
    n_cards=50,
    difficulty="advanced",
    tags=["Robbins", "General_Pathology", "Inflammation"]
)

# Add image occlusion for diagrams
for diagram in content.diagrams:
    occlusion_cards = creator.create_image_occlusion(
        image=diagram,
        auto_detect_labels=True
    )
    cards.extend(occlusion_cards)

# Export Anki package
creator.export_apkg(
    cards=cards,
    deck_name="Robbins_Inflammation",
    output_path="robbins_inflammation.apkg"
)

print(f"Created {len(cards)} cards ready for Anki import")
```

## Quality Checklist

**Card Quality:**
- [ ] One fact per card (atomicity)
- [ ] Clear, unambiguous questions
- [ ] Answers specific and complete
- [ ] Cloze deletions don't give away answer
- [ ] Images high resolution and relevant
- [ ] Tags hierarchical and consistent

**Educational Value:**
- [ ] Cards test high-yield information
- [ ] Difficulty appropriate for level
- [ ] Connections between related concepts
- [ ] Clinical context included where relevant
- [ ] No duplicate or near-duplicate cards

**Technical Quality:**
- [ ] Valid Anki format (import tested)
- [ ] Media files properly linked
- [ ] UTF-8 encoding for special characters
- [ ] CSS styling readable on mobile
- [ ] Card types appropriate for content

**Before Study:**
- [ ] **CRITICAL**: Review cards for accuracy
- [ ] **CRITICAL**: Delete cards for mastered material
- [ ] Personalize with own mnemonics
- [ ] Adjust card order if needed
- [ ] Set appropriate daily review limits

## Common Pitfalls

**Content Issues:**
- ❌ **Too much information** → "Cramming" cards with multiple facts
  - ✅ One concept per card; break complex topics into multiple cards

- ❌ **Memorization without understanding** → Memorizing without context
  - ✅ Include "why" and clinical significance

- ❌ **Outdated information** → Old guidelines or disproven theories
  - ✅ Verify against current textbooks and guidelines

**Card Design Issues:**
- ❌ **Ambiguous clozes** → "The {{c1::liver}} produces {{c2::bile}}" (which one is being asked?)
  - ✅ Clear question: "The liver produces ?" or "What organ produces bile?"

- ❌ **Overlapping cards** → Testing same fact multiple ways
  - ✅ Merge redundant cards; each fact tested once optimally

- ❌ **Recognition vs. recall** → Cards too easy (recognition only)
  - ✅ Use cloze deletions and type-in cards for active recall

**Study Strategy Issues:**
- ❌ **Too many new cards** → 100+ new cards/day leads to burnout
  - ✅ Sustainable pace: 20-30 new cards/day

- ❌ **No review of missed cards** → Ignoring leeches
  - ✅ Tag and review difficult cards separately

- ❌ **Passive card creation** → Making cards without studying
  - ✅ Create cards for immediate use; don't build massive backlog

# Anatomy Quiz Master

## Overview

Comprehensive anatomy education tool that generates interactive quizzes covering gross anatomy, neuroanatomy, and clinical anatomy with adaptive difficulty and detailed explanations.

**Key Capabilities:**
- **Regional Quizzes**: Head/neck, thorax, abdomen, pelvis, limbs
- **Multiple Question Types**: Identification, function, clinical correlation
- **Adaptive Difficulty**: Basic, intermediate, advanced levels
- **Image Integration**: Label identification with anatomical images
- **Progress Tracking**: Performance analytics and weak area identification
- **Exam Mode**: Timed simulations for USMLE-style preparation

## When to Use

**✅ Use this skill when:**
- Medical students preparing for anatomy practical exams
- Self-assessment after anatomy lectures or dissections
- Identifying weak anatomical regions for focused study
- Creating practice questions for study groups
- Remediation for students who failed anatomy assessments
- Preparing for USMLE Step 1 anatomy questions
- Teaching assistants generating quiz materials for labs

**❌ Do NOT use when:**
- Primary learning resource for anatomy → Use textbooks/atlas first
- Substitute for cadaver lab attendance → Use for supplemental practice only
- Pathology or physiology questions → Use specialized skills for those topics
- Board exam registration or scheduling → Use official NBME resources

**Integration:**
- **Upstream**: `usmle-case-generator` (clinical context), `anki-card-creator` (flashcard export)
- **Downstream**: `study-limitations-drafter` (weakness analysis), `performance-tracker` (progress monitoring)

## Core Capabilities

### 1. Regional Anatomy Quizzes

Generate focused quizzes by body region:

```python
from scripts.quiz_generator import QuizGenerator

generator = QuizGenerator()

# Generate thorax quiz
quiz = generator.generate_quiz(
    region="thorax",
    topics=["heart", "lungs", "mediastinum", "thoracic_wall"],
    difficulty="intermediate",
    n_questions=20
)

# Export for LMS
quiz.export(format="json", filename="thorax_quiz.json")
```

**Supported Regions:**
| Region | Subtopics | Question Types |
|--------|-----------|----------------|
| **Head & Neck** | Skull, cranial nerves, triangles, viscera | Identification, pathways, clinical |
| **Thorax** | Heart, lungs, mediastinum, pleura | Relations, auscultation, imaging |
| **Abdomen** | GI tract, retroperitoneum, vessels | Peritoneal reflections, vascular supply |
| **Pelvis** | Organs, perineum, walls | Gender differences, clinical correlations |
| **Upper Limb** | Shoulder, arm, forearm, hand | Muscle actions, innervation, clinical |
| **Lower Limb** | Hip, thigh, leg, foot | Gait, compartments, clinical exams |
| **Back** | Vertebral column, spinal cord, muscles | Levels, landmarks, clinical |

### 2. Neuroanatomy Pathway Tracing

Specialized quizzes for neural pathways:

```python
# Neuroanatomy quiz
neuro_quiz = generator.generate_neuro_quiz(
    pathway_type="motor",  # or "sensory", "cranial_nerves", "reflexes"
    include_lesions=True,
    clinical_correlations=True
)
```

**Pathway Types:**
- **Motor Pathways**: Corticospinal, corticobulbar, basal ganglia circuits
- **Sensory Pathways**: Dorsal column, spinothalamic, trigeminal
- **Cranial Nerves**: All 12 nerves with nuclei and clinical tests
- **Reflex Arcs**: Deep tendon, superficial, visceral
- **Vascular**: Arterial supply, venous drainage, stroke syndromes

### 3. Clinical Correlation Questions

Integrate anatomy with clinical scenarios:

```python
clinical_quiz = generator.generate_clinical_quiz(
    region="abdomen",
    scenario_types=["surgery", "radiology", "physical_exam"],
    difficulty="advanced"
)
```

**Question Formats:**
```
Clinical Scenario:
"A 45-year-old male presents with epigastric pain radiating to the back. 
CT shows a mass in the lesser sac."

Question: "Which artery runs immediately posterior to the body of the 
pancreas and would be at risk during resection?"

A) Splenic artery
B) Superior mesenteric artery
C) Common hepatic artery
D) Left gastric artery

Correct: B) Superior mesenteric artery

Explanation: The SMA emerges from the aorta at L1 and passes posterior 
to the neck of the pancreas and anterior to the uncinate process...
```

### 4. Adaptive Learning System

Adjust difficulty based on performance:

```python
from scripts.adaptive import AdaptiveEngine

engine = AdaptiveEngine()

# Track student performance
student_progress = engine.track_performance(
    student_id="student_001",
    quiz_results=results,
    time_per_question=True
)

# Generate personalized quiz targeting weak areas
personalized = engine.generate_adaptive_quiz(
    student_progress=student_progress,
    focus_areas=["thorax_vessels", "cranial_nerves"],
    mastery_threshold=0.80
)
```

**Adaptive Features:**
- **Spaced Repetition**: Re-test incorrect topics at optimal intervals
- **Difficulty Scaling**: Increase level after 3 consecutive correct answers
- **Time Pressure**: Gradually reduce time limits for speed practice
- **Weakness Identification**: Track performance by anatomical structure

## Common Patterns

### Pattern 1: Pre-Exam Comprehensive Review

**Scenario**: Student preparing for anatomy practical exam in 2 weeks.

```bash
# Generate full-body comprehensive quiz
python scripts/main.py \
  --mode comprehensive \
  --regions all \
  --difficulty intermediate \
  --n-questions 100 \
  --timed \
  --output pre_practice_exam.json

# Focus on weak areas identified
python scripts/main.py \
  --mode adaptive \
  --focus abdomen,pelvis \
  --difficulty advanced \
  --n-questions 30 \
  --output weak_areas_review.json
```

**Study Schedule:**
- Week 1: Comprehensive quizzes (all regions)
- Week 2: Focus on <80% score regions
- 3 days before: Timed practice exam
- Day before: Light review of marked difficult questions

### Pattern 2: Lab Session Preparation

**Scenario**: Student preparing for cadaver lab on upper limb.

```python
# Pre-lab identification quiz
pre_lab = generator.generate_image_quiz(
    region="upper_limb",
    structure_types=["muscles", "vessels", "nerves"],
    label_type="pins",  # Pin identification format
    n_questions=15
)

# Clinical correlation for post-lab
post_lab_clinical = generator.generate_clinical_quiz(
    region="upper_limb",
    clinical_types=["fractures", "nerve_injuries", "vascular"]
)
```

**Lab Integration:**
- Pre-lab: 15-minute identification quiz
- During lab: Reference key landmarks
- Post-lab: Clinical correlation quiz linking anatomy to disease

### Pattern 3: USMLE Step 1 Preparation

**Scenario**: Medical student preparing for USMLE Step 1.

```bash
# USMLE-style clinical anatomy
python scripts/main.py \
  --mode usmle \
  --clinical-focus \
  --mix-basic-advanced 70:30 \
  --n-questions 40 \
  --timed-per-question 60 \
  --output usmle_anatomy_practice.json
```

**USMLE Features:**
- Clinical vignette format
- Image-based questions (radiology, pathology)
- Two-step reasoning (identify structure → clinical implication)
- Time pressure simulation (60-90 seconds per question)

### Pattern 4: Teaching Assistant Lab Quiz

**Scenario**: TA needs to generate weekly lab quizzes.

```python
# Weekly lab quiz
ta_quiz = generator.generate_ta_quiz(
    week_number=5,
    region="thorax",
    practical_stations=8,
    time_per_station=3,  # minutes
    include_prosection_images=True
)

# Auto-generate answer key
answer_key = ta_quiz.generate_answer_key(
    include_acceptable_variations=True,
    grading_rubric="partial_credit"
)
```

**TA Tools:**
- Station-based practical exam format
- Answer keys with acceptable variations
- Grading rubrics
- Performance statistics by question

## Complete Workflow Example

**Comprehensive anatomy study session:**

```bash
# Step 1: Diagnostic quiz to identify weak areas
python scripts/main.py \
  --mode diagnostic \
  --regions all \
  --n-questions 50 \
  --output diagnostic_results.json

# Step 2: Generate focused study plan
python scripts/main.py \

    student_id="med_student_001",
    threshold=0.70
)
print(f"Focus next session on: {weak_areas}")
```

## Quality Checklist

**Question Quality:**
- [ ] Anatomical accuracy verified against standard atlases (Netter, Gray's)
- [ ] Clinical correlations reviewed by licensed physicians
- [ ] Multiple difficulty levels appropriately calibrated
- [ ] Distractors (wrong answers) are plausible and educational
- [ ] Explications explain *why* correct answer is right
- [ ] Image quality sufficient for identification (resolution, labeling)

**Educational Value:**
- [ ] Questions test high-yield anatomy (clinically relevant)
- [ ] Progressive difficulty builds knowledge systematically
- [ ] Clinical scenarios reflect real patient presentations
- [ ] Explanations include anatomical reasoning

**Technical Quality:**
- [ ] Randomization prevents pattern recognition
- [ ] No duplicate questions in quiz banks
- [ ] Image files properly licensed or original
- [ ] Accessibility compliance (alt text for images)

**Before Use:**
- [ ] **CRITICAL**: Faculty review for anatomical accuracy
- [ ] Pilot test with target student population
- [ ] Time limits appropriate for difficulty
- [ ] Answer key double-checked for errors

## Common Pitfalls

**Content Issues:**
- ❌ **Outdated anatomical knowledge** → Teaching old terminology
  - ✅ Use current Terminologia Anatomica standards

- ❌ **Nit-picky details** → Testing obscure structures rarely clinically relevant
  - ✅ Focus on high-yield anatomy that appears in clinical practice

- ❌ **Unclear images** → Poor resolution or confusing labels
  - ✅ Use high-quality images; test label legibility at screen resolution

**Educational Issues:**
- ❌ **Questions too easy** → No learning benefit
  - ✅ Calibrate to student level; aim for 60-80% success rate

- ❌ **No clinical context** → Pure memorization without application
  - ✅ Include clinical correlation questions

- ❌ **Punitive difficulty** → Discouraging rather than challenging
  - ✅ Provide encouraging feedback; focus on improvement

**Technical Issues:**
- ❌ **Predictable patterns** → Students game the system
  - ✅ Randomize question order and distractor placement

- ❌ **No progress tracking** → Can't identify weak areas
  - ✅ Implement analytics to guide focused study

# Adverse Event Narrative Generator

## Overview

Regulatory-grade narrative generation tool that transforms adverse event case data into CIOMS-compliant ICSR narratives suitable for submission to FDA, EMA, and other health authorities.

**Key Capabilities:**
- **CIOMS I Compliance**: Standardized narrative structure per international guidelines
- **ICH E2B Integration**: Electronic submission format compatibility
- **Temporal Analysis**: Timeline reconstruction and causality assessment
- **Medical Accuracy**: Clinical terminology and MedDRA coding
- **Multi-Case Processing**: Batch narrative generation for periodic reporting
- **Quality Validation**: Automated checks for completeness and consistency

## When to Use

**✅ Use this skill when:**
- Drafting ICSR narratives for regulatory submissions
- Converting safety case data to standardized text
- Preparing adverse event reports for health authorities
- Generating case summaries for signal detection
- Creating pharmacovigilance documentation for clinical trials
- Standardizing narrative format across safety teams
- Training new drug safety associates on narrative writing

**❌ Do NOT use when:**
- Case requires medical judgment or causality assessment → Use qualified safety physician
- Narrative for litigation or legal proceedings → Use legal documentation standards
- Patient-facing communications → Use `lay-summary-gen`
- Aggregate safety summaries → Use `safety-summary-reports`
- Coding MedDRA terms from verbatim → Use `meddra-coder`

**Integration:**
- **Upstream**: `meddra-coder` (MedDRA term coding), `clinical-data-cleaner` (data preparation)
- **Downstream**: `safety-summary-reports` (aggregate analysis), `regulatory-submission-prep` (FDA/EMA filing)

## Core Capabilities

### 1. CIOMS I Narrative Structure

Generate standardized sections per CIOMS guidelines:

```python
from scripts.narrative_generator import NarrativeGenerator

generator = NarrativeGenerator()

# Generate complete narrative
narrative = generator.generate(
    case_data=case_json,
    format="cioms_i",  # or "ich_e2b", "fda_medwatch"
    include_meddra=True
)

narrative.save("ICSR_2024_001_narrative.txt")
```

**Standard Sections:**
1. **Patient Demographics** - Age, sex, weight, relevant characteristics
2. **Medical History** - Significant pre-existing conditions
3. **Concomitant Medications** - Other drugs at time of event
4. **Suspect Drug(s)** - Medication(s) in question with dosing
5. **Adverse Event** - Detailed reaction description with MedDRA terms
6. **Diagnostic Results** - Lab values, imaging, procedures
7. **Treatment** - Medical management of the event
8. **Dechallenge/Rechallenge** - Effect of drug withdrawal/reintroduction
9. **Outcome** - Final patient status and sequelae
10. **Causality Assessment** - Reporter's relationship evaluation

### 2. Temporal Relationship Analysis

Reconstruct timeline and assess temporal plausibility:

```python
# Analyze temporal relationships
timeline = generator.analyze_timeline(
    drug_start="2024-01-15",
    drug_stop="2024-02-01",
    ae_onset="2024-01-28",
    dechallenge_date="2024-02-01",
    rechallenge_date=None
)

# Output shows temporal assessment
# "AE onset 13 days after drug initiation, positive dechallenge within 24h"
```

**Assessments Generated:**
- Time to onset (latency period)
- Dechallenge response (positive/negative/unknown)
- Rechallenge response (if applicable)
- Temporal plausibility (consistent with known drug profile)

### 3. Causality Evaluation Support

Structure causality assessment per WHO-UMC criteria:

```python
# Generate causality section
causality = generator.assess_causality(
    case_data=case,
    criteria="who_umc",  # or "naranjo", "cochrane"
    include_rationale=True
)

# Output structured assessment with points for each criterion
```

**WHO-UMC Categories:**
- **Certain** - Event reproduced on rechallenge
- **Probable/Likely** - Reasonable time, positive dechallenge, alternative causes unlikely
- **Possible** - Compatible time, but alternative causes possible
- **Unlikely** - Incompatible time or alternative cause probable
- **Conditional/Unclassified** - Insufficient information
- **Unassessable/Unclassifiable** - Data contradictory or incomplete

### 4. Multi-Format Output

Generate narratives for different regulatory contexts:

```python
# FDA MedWatch Form 3500A
fda_narrative = generator.generate(
    case_data=case,
    format="fda_medwatch",
    max_length=2000  # Character limit
)

# EMA E2B(R3) electronic format
ema_narrative = generator.generate(
    case_data=case,
    format="ich_e2b",
    version="R3"
)

# CIOMS I paper format
cioms_narrative = generator.generate(
    case_data=case,
    format="cioms_i"
)
```

## Common Patterns

### Pattern 1: Serious Adverse Event (Hospitalization)

**Scenario**: Patient hospitalized for severe drug reaction.

```json
{
  "case_id": "2024-SAE-001",
  "patient_age": "58 years",
  "patient_sex": "Female",
  "suspect_drugs": [{
    "drug_name": "Metformin",
    "dose": "1000 mg BID",
    "dates": "2024-01-15 to 2024-02-01"
  }],
  "adverse_events": [{
    "meddra_pt": "Lactic acidosis",
    "seriousness": "Hospitalization",
    "onset": "2024-01-28"
  }],
  "outcome": "Recovered with sequelae"
}
```

**Narrative Emphasis:**
- Hospitalization details (admission/discharge dates)
- Severity markers (ICU stay, intubation)
- Lactate levels and trend
- Renal function status
- Complete recovery timeline

### Pattern 2: Fatal Outcome Case

**Scenario**: Death suspected to be drug-related.

```python
# Fatal case handling
narrative = generator.generate(
    case_data=fatal_case,
    format="cioms_i",
    include_autopsy=True,
    cause_of_death_analysis=True
)
```

**Critical Elements:**
- Complete medical history relevant to death
- Concomitant medications contributing
- Autopsy findings (if performed)
- Cause of death per death certificate
- Alternative causes ruled out
- Reporter's opinion on contribution to death

### Pattern 3: Rechallenge Case

**Scenario**: Positive rechallenge confirms drug causation.

**Key Documentation:**
- First exposure dates and reaction
- Dechallenge response
- Rechallenge dates and circumstances
- Recurrence of same reaction
- Any differences in severity
- Conclusion on causality

**Narrative Structure:**
```
First Exposure:
- Drug X initiated [date]
- AE occurred [date], [description]
- Drug discontinued [date]
- Dechallenge: [positive/negative]

Rechallenge:
- Drug X reintroduced [date]
- Same AE recurred [date]
- Drug discontinued [date]
- Outcome: [status]

Causality: Certain (positive rechallenge)
```

### Pattern 4: Multi-Drug Reaction

**Scenario**: Multiple suspect drugs, need to identify most likely culprit.

**Analysis Approach:**
- Temporal sequence of drug initiations
- Time to onset for each drug
- Known adverse reaction profiles
- Dechallenge attempts (if any)
- Rechallenge data (if any)
- Reporter's primary suspect

**Narrative Organization:**
1. List all suspect drugs with indication and dates
2. Describe temporal relationship for each
3. Discuss dechallenge/rechallenge for each
4. Present reporter's causality assessment
5. Include alternative explanations

## Complete Workflow Example

**From case data to regulatory submission:**

```bash
# Step 1: Generate narrative
python scripts/main.py \
  --input case_data.json \
  --format cioms_i \
  --output narrative.txt

# Step 2: Validate completeness
python scripts/validate.py \
  --narrative narrative.txt \
  --check cioms_completeness \
  --output validation_report.txt

# Step 3: Generate E2B format for electronic submission
python scripts/main.py \
  --input case_data.json \
  --format ich_e2b \
  --output e2b_narrative.xml

# Step 4: Medical review markup
python scripts/review.py \
  --narrative narrative.txt \
  --output review_version.txt
```

**Python API:**

```python
from scripts.narrative_generator import NarrativeGenerator
from scripts.validator import NarrativeValidator

# Initialize
generator = NarrativeGenerator()
validator = NarrativeValidator()

# Load case data
import json
with open("case_001.json", "r") as f:
    case = json.load(f)

# Generate narrative
narrative = generator.generate(
    case_data=case,
    format="cioms_i",
    include_meddra=True,
    language="en"
)

# Validate
validation = validator.check(
    narrative=narrative,
    criteria=["cioms_completeness", "temporal_logic", "meddra_accuracy"]
)

if validation.passed:
    with open("final_narrative.txt", "w") as f:
        f.write(narrative.text)
    print("✓ Narrative validated and saved")
else:
    print(f"⚠ Issues: {validation.issues}")
```

## Quality Checklist

**Pre-Generation:**
- [ ] Case ID unique and formatted per SOP
- [ ] Patient age/sex complete
- [ ] Suspect drug(s) clearly identified
- [ ] Adverse event(s) coded with MedDRA PT
- [ ] Dates consistent (no future dates)
- [ ] Reporter information included

**Narrative Content:**
- [ ] All CIOMS I sections present
- [ ] Temporal sequence clear and logical
- [ ] Dechallenge/rechallenge described (if applicable)
- [ ] Lab values with reference ranges
- [ ] Concomitant medications listed
- [ ] Medical history relevant to event
- [ ] Outcome clearly stated
- [ ] Causality assessment justified

**Post-Generation:**
- [ ] MedDRA terms accurate and current
- [ ] No contradictory information
- [ ] Language objective and factual
- [ ] No speculation or opinion (except causality section)
- [ ] Patient identifiers removed or de-identified
- [ ] **CRITICAL**: Medical review completed
- [ ] **CRITICAL**: Causality assessment by qualified physician

## Common Pitfalls

**Completeness Issues:**
- ❌ **Missing dechallenge information** → Cannot assess causality
  - ✅ Always document effect after drug discontinuation

- ❌ **Vague temporal information** → "Recently started" vs. specific dates
  - ✅ Use exact dates when available

- ❌ **Incomplete concomitant medication list** → Alternative causes missed
  - ✅ Include all medications within relevant timeframe

**Medical Accuracy Issues:**
- ❌ **Incorrect MedDRA coding** → Wrong medical concept
  - ✅ Use current MedDRA version; verify with medical reviewer

- ❌ **Confusing correlation with causation** → Temporal = causal
  - ✅ Clearly state "temporally associated" vs. "causally related"

- ❌ **Omitting alternative diagnoses** → Biased toward drug causation
  - ✅ Include all differential diagnoses considered

**Regulatory Issues:**
- ❌ **Opinion in narrative body** → "Clearly caused by drug"
  - ✅ Reserve opinion for causality section; narrative should be factual

- ❌ **Patient identifiers** → HIPAA/privacy violation
  - ✅ De-identify per regulatory requirements

- ❌ **Abbreviations not defined** → Assumes reader knowledge
  - ✅ Spell out on first use in each narrative

# CIOMS I: International Reporting of Adverse Drug Reactions

## Overview

The CIOMS (Council for International Organizations of Medical Sciences) Form I provides a standardized format for the exchange of individual case safety reports (ICSRs) between pharmaceutical companies and regulatory authorities worldwide.

## Key Components

### 1. Administrative Information
- Case identifier
- Report date
- Primary source (reporter) information
- Type of report (initial/follow-up)

### 2. Patient Information
- Age (at time of event)
- Sex
- Weight and height (if relevant)
- Special populations (pregnancy, elderly, pediatric)

### 3. Suspect Drug(s)
- Name (proprietary or established)
- Dose, frequency, route
- Therapy dates (start/stop)
- Indication
- Batch/lot number

### 4. Adverse Event
- Description of reaction
- Onset date
- Outcome
- Seriousness criteria

### 5. Other Relevant Information
- Concomitant medications
- Medical history
- Diagnostic test results
- Dechallenge/Rechallenge results

## Narrative Writing Guidelines

### Structure
The narrative should tell a complete story in chronological order:
1. Who (patient demographics)
2. Why (medical history, indication)
3. What (suspect drug)
4. When (therapy dates, event onset)
5. What happened (event description)
6. How it was managed (treatment)
7. Outcome

### Language Requirements
- Use clear, concise medical English
- Avoid abbreviations (unless standard medical terms)
- Use MedDRA preferred terms for events
- Include temporal relationships explicitly
- State facts, avoid speculation

### Critical Elements to Include
- Time to onset from first dose
- Dechallenge information (did event resolve after stopping drug?)
- Rechallenge information (did event recur on re-exposure?)
- Alternative etiologies considered
- Relevant laboratory abnormalities

### Elements to Exclude
- Patient identifiers (names, initials, medical record numbers)
- Reporter contact details (in narrative)
- Company confidential information
- Speculative statements without evidence

## Seriousness Criteria (ICH E2A)

An adverse event is considered serious if it results in:
- Death
- Life-threatening
- Hospitalization (initial or prolonged)
- Disability/incapacity
- Congenital anomaly/birth defect
- Other medically important condition

## Causality Assessment Categories

| Category | Definition |
|----------|------------|
| Certain | Event occurs with plausible time relationship, cannot be explained by disease/other drugs, confirmed by dechallenge/rechallenge |
| Probable/Likely | Reasonable time sequence, unlikely to be attributed to disease/other drugs, response to withdrawal clinically reasonable |
| Possible | Reasonable time sequence, could also be explained by disease/other drugs |
| Unlikely | Time relationship implausible, disease/other drugs provide plausible explanation |
| Conditional/Unclassified | More data required for assessment |
| Unassessable/Unclassifiable | Insufficient information to assess |

3. Multiple PTs may be needed for complex events
4. Include LLT (Lowest Level Terms) if specific diagnosis not confirmed
5. Update coding as more information becomes available

# Quick Reference Guide

## Running the Narrative Generator

```bash
# Basic usage
python scripts/main.py --input case_data.json

# Save to file
python scripts/main.py --input case_data.json --output narrative.txt

# Validate input only
python scripts/main.py --input case_data.json --validate-only
```

## Required JSON Structure

```json
{
  "case_id": "string",
  "patient_age": "string (e.g., '45 years')",
  "patient_sex": "Male/Female/Unknown",
  "suspect_drugs": [...],
  "adverse_events": [...]
}
```

## Common Errors and Solutions

| Error | Solution |
|-------|----------|
| Missing required field | Add the missing field to JSON |
| Invalid JSON | Check JSON syntax with validator |
| File not found | Check file path |

## Output Sections

The narrative includes these sections in order:
1. Case identifier and date
2. Patient demographics
3. Medical history
4. Concomitant medications
5. Suspect drug(s)
6. Adverse event(s)
7. Diagnostic tests
8. Treatment
9. Dechallenge/rechallenge
10. Outcome
11. Causality assessment
12. Reporter comments

## CIOMS Compliance Checklist

Ensure your narrative includes:
- [ ] Patient age and sex (anonymized)
- [ ] Suspect drug name and indication
- [ ] Dose and therapy dates
- [ ] Event description with MedDRA term
- [ ] Onset date or latency
- [ ] Seriousness criteria
- [ ] Dechallenge result
- [ ] Final outcome
- [ ] Causality assessment

# Abstract Summarizer

## Overview

AI-powered academic summarization tool that condenses complex research papers into publication-ready structured abstracts while preserving scientific accuracy and key findings.

**Key Capabilities:**
- **Multi-Format Input**: Process PDFs, text, URLs, or clipboard content
- **Structured Output**: Background, Objective, Methods, Results, Conclusion format
- **Word Count Enforcement**: Strict 250-word limit with validation
- **Quantitative Preservation**: Retains key numbers, statistics, and effect sizes
- **Discipline Adaptation**: Optimized for STEM, medical, and social sciences
- **Batch Processing**: Summarize multiple papers efficiently

## When to Use

**✅ Use this skill when:**
- Creating conference abstracts from full papers
- Preparing literature review summaries
- Quickly assessing paper relevance for reading decisions
- Generating executive summaries for stakeholders
- Drafting journal submission abstracts
- Teaching students how to write scientific abstracts
- Building annotated bibliographies

**❌ Do NOT use when:**
- Source material is highly nuanced philosophy/literary critique → Use `humanities-text-analyzer`
- Mathematical proofs require detailed explanation → Use `math-theorem-simplifier`
- Legal documents or contracts → Use `legal-document-summarizer`
- Creative writing or fiction → Use `creative-writing-editor`
- Patient medical records (HIPAA concerns) → Use clinical documentation tools only

**Integration:**
- **Upstream**: `pdf-text-extractor` (content extraction), `citation-formatter` (reference handling)
- **Downstream**: `conference-abstract-adaptor` (format adjustment), `journal-matchmaker` (submission prep)

## Core Capabilities

### 1. Structured Abstract Generation

Extract and condense key sections into standard format:

```python
from scripts.summarizer import AbstractSummarizer

summarizer = AbstractSummarizer()

# Generate from PDF
abstract = summarizer.summarize(
    source="paper.pdf",
    format="structured",  # structured, plain, or executive
    word_limit=250,
    discipline="biomedical"  # affects terminology handling
)

print(abstract.text)
# Output: Background → Objective → Methods → Results → Conclusion
```

**Output Structure:**
```
**Background**: [Context and problem statement]
**Objective**: [Research goal and hypotheses]
**Methods**: [Study design, sample, key methods]
**Results**: [Primary findings with statistics]
**Conclusion**: [Implications and significance]

---
Word count: 247/250
```

### 2. Quantitative Data Preservation

Ensure numbers and statistics are accurately retained:

```python
# Extract and verify quantitative results
quant_results = summarizer.extract_quantitative(
    text=paper_content,
    priority="high"  # keep all numbers vs. representative samples
)

# Validate against original
validation = summarizer.verify_accuracy(
    abstract=abstract,
    source=paper_content
)
```

**Preserves:**
- Sample sizes (n=128)
- Effect sizes (Cohen's d = 0.82)
- P-values (p < 0.001)
- Confidence intervals (95% CI: [0.45, 0.78])
- Percentages and absolute numbers

### 3. Multi-Disciplinary Adaptation

Adjust extraction strategy by field:

```bash
# Biomedical paper
python scripts/main.py --input paper.pdf --field biomedical

# Physics paper  
python scripts/main.py --input paper.pdf --field physics

# Social science paper
python scripts/main.py --input paper.pdf --field social-science
```

**Field-Specific Handling:**
| Field | Focus Areas | Special Handling |
|-------|-------------|------------------|
| **Biomedical** | Study design, statistical significance, clinical relevance | Preserve P-values, effect sizes |
| **Physics** | Theoretical framework, experimental setup, precision | Keep measurement uncertainties |
| **CS/Engineering** | Algorithm performance, benchmarks, complexity | Retain accuracy percentages |
| **Social Science** | Methodology, sample demographics, theoretical contribution | Preserve effect descriptions |

### 4. Batch Literature Processing

Summarize multiple papers for systematic reviews:

```python
from scripts.batch import BatchProcessor

batch = BatchProcessor()

# Process directory of papers
summaries = batch.summarize_directory(
    directory="literature_review/",
    output_format="csv",  # or json, markdown
    include_metadata=True  # title, authors, year
)

# Generate review matrix
matrix = batch.create_summary_matrix(summaries)
matrix.save("review_matrix.csv")
```

**Output:**
- Individual abstract files
- Comparative summary table
- Key findings synthesis document

## Common Patterns

### Pattern 1: Clinical Trial Summary

**Template for RCTs and clinical studies:**

```json
{
  "paper_type": "clinical_trial",
  "key_elements": [
    "Study design (RCT, cohort, case-control)",
    "Population (n, inclusion/exclusion)",
    "Intervention details",
    "Primary endpoint",
    "Key results (efficacy, safety)",
    "Clinical significance"
  ],
  "emphasis": "P-values, confidence intervals, adverse events"
}
```

**Example Output:**
```
**Background**: Current treatments for X disease have limited efficacy.
**Objective**: Evaluate Drug Y's safety and efficacy in patients with X.
**Methods**: Double-blind RCT (n=342) comparing Drug Y vs placebo for 12 weeks.
**Results**: Primary endpoint achieved (67% vs 32% response, p<0.001, OR=4.2). 
            Adverse events mild (headache 12%, nausea 8%).
**Conclusion**: Drug Y significantly improves outcomes with acceptable safety profile.
```

### Pattern 2: Basic Science Research

**Template for laboratory/mechanistic studies:**

```json
{
  "paper_type": "basic_science",
  "key_elements": [
    "Research question/hypothesis",
    "Model system (cell line, animal, in vitro)",
    "Key methods (CRISPR, Western blot, etc.)",
    "Mechanistic findings",
    "Biological significance"
  ],
  "emphasis": "Molecular mechanisms, pathway diagrams"
}
```

**Example Output:**
```
**Background**: The role of Protein X in Disease Y progression is unknown.
**Objective**: Determine if Protein X regulates Pathway Z in Disease Y.
**Methods**: CRISPR knockout in cell lines, Western blot analysis, mouse model.
**Results**: Protein X deletion reduced Pathway Z activation by 78% (p<0.01). 
            In vivo, knockout mice showed 45% less disease progression.
**Conclusion**: Protein X is a critical regulator of Pathway Z and potential therapeutic target.
```

### Pattern 3: Meta-Analysis Summary

**Template for systematic reviews and meta-analyses:**

```json
{
  "paper_type": "meta_analysis",
  "key_elements": [
    "Search strategy and databases",
    "Number of studies included",
    "Total sample size",
    "Pooled effect size",
    "Heterogeneity assessment",
    "Quality of evidence"
  ],
  "emphasis": "I² values, funnel plots, GRADE assessment"
}
```

**Example Output:**
```
**Background**: Previous trials of Intervention X show conflicting results.
**Objective**: Systematically evaluate efficacy through meta-analysis.
**Methods**: PRISMA-guided search of PubMed, Embase, Cochrane (through 2024). 
            23 RCTs (n=4,847) met inclusion criteria.
**Results**: Significant benefit observed (SMD=0.42, 95% CI [0.28, 0.56], p<0.001). 
            Moderate heterogeneity (I²=45%). Quality: moderate.
**Conclusion**: Intervention X shows modest efficacy with moderate certainty evidence.
```

### Pattern 4: Methodology/Algorithm Paper

**Template for methods and computational papers:**

```json
{
  "paper_type": "methodology",
  "key_elements": [
    "Problem with existing methods",
    "Novel approach description",
    "Key innovations",
    "Performance benchmarks",
    "Comparison to state-of-the-art"
  ],
  "emphasis": "Accuracy, speed, scalability metrics"
}
```

**Example Output:**
```
**Background**: Current algorithms for Problem X are computationally expensive.
**Objective**: Develop efficient method with improved accuracy.
**Methods**: Novel graph neural network architecture with attention mechanism. 
            Validated on 5 benchmark datasets.
**Results**: 3.2× faster than current methods with 12% accuracy improvement 
            (p<0.001). Scales to datasets with 10M+ nodes.
**Conclusion**: Method achieves superior performance with practical computational requirements.
```

    discrepancies = validator.get_discrepancies()
    print(f"Review needed: {discrepancies}")
```

## Quality Checklist

**Pre-Summarization:**
- [ ] Source document is complete (not truncated)
- [ ] PDF/text is machine-readable (not scanned images)
- [ ] Document is research paper (not editorial, review, or news)

**During Summarization:**
- [ ] All key sections identified (don't miss Results)
- [ ] Quantitative data preserved accurately
- [ ] Statistical significance indicators kept
- [ ] No interpretation added beyond source

**Post-Summarization:**
- [ ] Word count ≤ 250
- [ ] All 5 sections present
- [ ] **CRITICAL**: Numbers match source document
- [ ] Standalone comprehensibility (makes sense without paper)
- [ ] No citations or references in abstract
- [ ] Technical terms used correctly

**Before Use:**
- [ ] **CRITICAL**: Fact-check all numbers against original
- [ ] Verify author names and affiliations correct
- [ ] Ensure conclusions don't overstate findings

## Common Pitfalls

**Accuracy Issues:**
- ❌ **Misrepresenting statistics** → "Significant improvement" when p>0.05
  - ✅ Preserve exact P-values and confidence intervals
  
- ❌ **Oversimplifying complex findings** → "Drug works" vs nuanced efficacy data
  - ✅ Include effect sizes and confidence intervals

- ❌ **Missing adverse events** → Only reporting positive results
  - ✅ Include safety data for clinical studies

**Structure Issues:**
- ❌ **Methods too detailed** → Protocol steps in abstract
  - ✅ High-level study design only

- ❌ **Results without context** → Numbers without interpretation
  - ✅ Brief clinical/scientific significance

- ❌ **Conclusion overstates** → "Cure for cancer" from preclinical data
  - ✅ Match conclusion to evidence level

**Word Count Issues:**
- ❌ **Exceeding 250 words** → Journal rejection
  - ✅ Strict enforcement with real-time counter

- ❌ **Too short (<150 words)** → Missing key information
  - ✅ Minimum thresholds by section

Title: Transformer-Based Multi-Modal Fusion for Medical Image Segmentation

Abstract
Medical image segmentation remains a challenging task due to the complexity 
of anatomical structures and the need for precise boundary detection. While 
convolutional neural networks (CNNs) have achieved remarkable success, they 
often struggle with capturing long-range dependencies. Vision Transformers 
(ViTs) have emerged as powerful alternatives but require large amounts of 
training data. In this work, we propose MedFusion-Transformer, a novel 
architecture that combines the local feature extraction capabilities of CNNs 
with the global context modeling of Transformers through a cross-attention 
mechanism.

We evaluated our approach on three publicly available datasets: BraTS 2020 
(brain tumor segmentation), LiTS (liver tumor segmentation), and ACDC 
(cardiac segmentation). Our method achieved Dice scores of 0.892 ± 0.034, 
0.856 ± 0.041, and 0.914 ± 0.028 respectively, outperforming the previous 
state-of-the-art by 2.3%, 1.8%, and 1.5%. Ablation studies demonstrate that 
the cross-attention fusion module contributes most to performance gains. 
Furthermore, our model requires 40% fewer parameters than comparable 
Transformer-based methods.

These results suggest that hybrid CNN-Transformer architectures offer a 
promising direction for medical image segmentation, particularly in 
data-scarce domains. Our code and trained models are available at 
https://github.com/example/medfusion.
```

## Expected Output

**Background**: Medical image segmentation faces challenges in capturing both local features and long-range dependencies, with CNNs and Transformers each having limitations.

**Objective**: To develop a hybrid architecture combining CNN local feature extraction with Transformer global context modeling for improved medical image segmentation.

**Methods**: We propose MedFusion-Transformer using cross-attention fusion, evaluated on BraTS 2020, LiTS, and ACDC datasets with Dice score metrics and ablation studies.

**Results**: Achieved Dice scores of 0.892 ± 0.034 (BraTS), 0.856 ± 0.041 (LiTS), and 0.914 ± 0.028 (ACDC), outperforming state-of-the-art by 2.3%, 1.8%, and 1.5% respectively while using 40% fewer parameters.

**Conclusion**: Hybrid CNN-Transformer architectures show promise for medical image segmentation, especially in data-scarce settings.

Title: Efficacy and Safety of Novel JAK Inhibitor XRZ-789 in Rheumatoid Arthritis: 
A Phase III Randomized Controlled Trial

Methods
This double-blind, placebo-controlled trial enrolled 482 adult patients with 
moderate-to-severe rheumatoid arthritis (RA) who had inadequate response to 
methotrexate. Participants were randomized 2:1 to receive XRZ-789 200mg daily 
(n=321) or placebo (n=161) for 24 weeks, with all patients receiving background 
methotrexate therapy. The primary endpoint was ACR20 response rate at week 24. 
Secondary endpoints included ACR50, ACR70, DAS28-CRP, and safety assessments.

Results
At week 24, ACR20 response was achieved by 68.2% (219/321) of patients in the 
XRZ-789 group versus 32.9% (53/161) in the placebo group (p<0.001, difference 
35.3%; 95% CI: 26.8-43.8). ACR50 and ACR70 responses were 42.4% versus 15.5% 
(p<0.001) and 23.7% versus 6.2% (p<0.001) respectively. Mean DAS28-CRP 
improvement was -2.1 in the XRZ-789 group versus -0.9 in placebo (p<0.001).

Adverse events occurred in 78.5% of XRZ-789 patients versus 71.4% of placebo 
patients. Serious infections were reported in 2.5% (n=8) of XRZ-789 patients 
versus 1.2% (n=2) of placebo. One case of pulmonary embolism occurred in the 
XRZ-789 group. No deaths were reported during the study period.

Conclusions
XRZ-789 demonstrated superior efficacy in treating RA patients with inadequate 
response to methotrexate, with a safety profile consistent with other JAK 
inhibitors. These findings support XRZ-789 as a new therapeutic option for 
this patient population.
```

## Expected Output

**Background**: Rheumatoid arthritis patients with inadequate response to methotrexate need effective alternative treatments.

**Objective**: To evaluate the efficacy and safety of XRZ-789, a novel JAK inhibitor, in patients with moderate-to-severe RA.

**Methods**: Double-blind RCT of 482 patients randomized 2:1 to XRZ-789 200mg daily (n=321) or placebo (n=161) for 24 weeks with background methotrexate. Primary endpoint: ACR20 at week 24. Secondary: ACR50/70, DAS28-CRP, safety.

**Results**: XRZ-789 achieved 68.2% ACR20 response vs 32.9% placebo (p<0.001, difference 35.3%; 95% CI: 26.8-43.8). ACR50: 42.4% vs 15.5%, ACR70: 23.7% vs 6.2% (both p<0.001). DAS28-CRP improvement: -2.1 vs -0.9 (p<0.001). Serious infections: 2.5% vs 1.2%. One pulmonary embolism in treatment group. No deaths.

**Conclusion**: XRZ-789 demonstrated superior efficacy with a safety profile consistent with other JAK inhibitors, supporting it as a new RA treatment option.

## Scoring Methodology

### Blockbuster Index Formula

```
Blockbuster Index = (Market Potential × 0.5) + (Maturity × 0.3) + (Momentum × 0.2)
```

### Component Scores

| Component | Weight | Factors |
|-----------|--------|---------|
| **Market Potential** | 50% | Market size, unmet need, competition |
| **Maturity** | 30% | Clinical stage, patent depth, funding stage |
| **Momentum** | 20% | Patent growth, funding activity, clinical progress |

### Investment Recommendation Thresholds

| Blockbuster Index | Recommendation | Action |
|-------------------|----------------|--------|
| ≥ 80 | **Strongly Recommended** | Prioritize R&D investment |
| 60-79 | **Recommended** | Active monitoring and early partnerships |
| 40-59 | **Watch** | Monitor milestones; reassess in 6-12 months |
| < 40 | **Cautious** | Minimal investment; consider divestment |

## Supported Technologies

description: Structures and writes discussion sections for academic papers and research reports. Use when writing a discussion section, interpreting research results, connecting findings to existing literature, addressing study limitations, synthesizing conclusions, or drafting any part of an academic discussion. Helps researchers organize arguments, contextualize data, and produce clear, publication-ready discussion prose.

# Discussion Section Architect

## Quick Start

1. Provide your **research question**, **key results**, and any **prior literature** you want to reference.
2. Choose a structure (see workflows below).
3. Generate a draft discussion section with clearly organized subsections.
4. Run the **Draft → Revise loop** (see below).

---

## Core Capabilities

### 1. Interpret and Contextualize Results

- State whether results support or contradict the original hypothesis.
- Explain unexpected findings with reasoned interpretations.
- Quantify effect sizes or patterns when relevant.

**Example prompt input:**
```
Results: Group A showed a 23% reduction in symptom severity (p=0.003) vs. control.
Hypothesis: Intervention would reduce symptom severity.
Task: Interpret this result for the discussion section.
```

**Example output excerpt:**
```
The 23% reduction in symptom severity (p=0.003) supports the primary hypothesis.
This effect size is clinically meaningful and consistent with the mechanistic
rationale proposed in the introduction...
```

---

### 2. Connect Findings to Existing Literature

- Identify studies that corroborate the findings.
- Highlight where results diverge from prior literature and offer explanations.
- Use hedged academic language appropriate to the field.

**Example:**
```
Finding: Effect was stronger in older participants.
Literature: Smith et al. (2019) found age-moderated responses in a similar cohort.
Task: Connect finding to literature.
```

**Output:**
```
The age-moderated effect aligns with Smith et al. (2019), who reported attenuated
responses in younger adults. One possible explanation is differential receptor
sensitivity across age groups, as suggested by...
```

---

### 3. Address Limitations

Draft a limitations subsection that is honest but does not undermine the contribution:

```
Limitation: [Describe constraint]
Impact: [How it affects interpretation]
Mitigation / Future direction: [How it could be addressed]
```

---

### 4. Synthesize Conclusions

Generate a closing paragraph that:

- Restates the core finding in plain language.
- States the theoretical or practical contribution.
- Ends with a forward-looking statement about implications or next steps.

---

## Recommended Discussion Structure

```
1. Opening: Restate the research question and summarize the key finding (2–3 sentences).
2. Interpretation: Explain what the results mean mechanistically or theoretically.
3. Comparison to Literature: Agree/contrast with prior studies; explain divergences.
4. Implications: Theoretical contributions and/or practical applications.
5. Limitations: Honest scope boundaries with future directions.
6. Conclusion: Synthesis and forward-looking close.
```

---

## Draft → Revise Loop

Use this iterative workflow after generating an initial draft:

**Step 1 — Draft**: Generate the full discussion section using the structure above.

**Step 2 — Check**: Review against the checklist:
- [ ] Each finding from the Results section is explicitly addressed.
- [ ] Claims are supported by citations or logical reasoning — not stated as facts.
- [ ] Unexpected or null results are acknowledged and interpreted.
- [ ] Limitations are stated without dismissing the study's contribution.
- [ ] No new data or results are introduced in the discussion.
- [ ] Hedged language used appropriately (e.g., "suggests," "indicates," "may reflect").
- [ ] Conclusion ties back to the original research question.

**Step 3 — Revise**: For each failed checklist item, revise only the affected paragraph(s).

**Step 4 — Re-check**: Re-run the checklist on revised paragraphs to confirm resolution before finalizing.

# NIH Data Management and Sharing Plan (DMSP) Template

**Source:** [NIH Data Management and Sharing Policy](https://sharing.nih.gov/data-management-and-sharing-policy)  
**Effective Date:** January 25, 2023  
**Version:** Final Policy

---

## Overview

This document provides the official template and guidance for preparing Data Management and Sharing Plans (DMSP) as required by the NIH Policy for Data Management and Sharing.

## Required Elements

NIH requires all six elements below to be addressed in a DMSP:

---

### 1. Data Type

**What to include:**
- Types and estimated amount of scientific data to be generated and/or used in the research
- Indicate whether existing data will be used
- Briefly describe the scientific data that will be shared
- List metadata, other relevant data, and any associated documentation that will be shared

**Key considerations:**
- NIH defines scientific data as "the recorded factual material commonly accepted in the scientific community as of sufficient quality to validate and replicate research findings"
- Describe data in sufficient detail for reviewers to understand what will be shared
- Include rationale for any scientific data that will not be shared

**Example language:**
```
This project will generate the following scientific data types:
- Raw sequencing reads (FASTQ format)
- Processed gene expression matrices
- Clinical metadata (de-identified)
- Analysis code and workflows

Estimated data volume: ~2 TB over the project period.

Data that will not be shared:
- Individual participant identifiers and direct identifiers per HIPAA Safe Harbor method
- Audio recordings of interviews (transcripts will be shared instead)
```

---

### 2. Related Tools, Software and/or Code

**What to include:**
- Tools and software needed to access and manipulate shared data
- Specialized tools or custom code developed for the project
- How to access the tools (open-source vs. proprietary)

**Key considerations:**
- Consider using open-source, widely available tools when possible
- If proprietary software is required, document version and licensing requirements
- Share custom code through public repositories (e.g., GitHub, Zenodo)

**Example language:**
```
Data will be accessible using standard bioinformatics tools including:
- R (v4.0+) with Bioconductor packages
- Python (v3.8+) with pandas, numpy, scipy
- Standard genome browsers (IGV, UCSC)

Custom analysis pipelines will be deposited in GitHub with DOI via Zenodo integration.
```

---

### 3. Standards

**What to include:**
- Standards to be applied to scientific data and metadata
- Data formats, terminologies/vocabularies, and ontologies
- Quality assurance/quality control procedures

**Key considerations:**
- Use community-accepted standards when available
- Document any departures from standard formats
- Include reference to specific standard versions

**Example language:**
```
Metadata Standards:
- Minimum Information About a Microarray Experiment (MIAME)
- Dublin Core metadata elements
- DataCite metadata schema

Data Formats:
- Raw data: FASTQ, BAM/CRAM
- Processed data: HDF5, TSV
- Metadata: JSON, XML

Ontologies:
- Gene Ontology (GO)
- Human Phenotype Ontology (HPO)
- NCI Thesaurus
```

---

### 4. Data Preservation, Access, and Associated Timelines

**What to include:**
- Repository(ies) where data will be archived
- How data will be findable (identifiers, metadata)
- When data will be made available
- Duration of data retention

**Key considerations:**
- Choose NIH-approved repositories when available
- Obtain persistent identifiers (DOIs, accession numbers)
- Data should be shared no later than the end of the award period (or at time of publication, whichever comes first)

**Example language:**
```
Repository Selection:
- Raw sequencing data: NCBI Sequence Read Archive (SRA)
- Processed data and metadata: GEO (Gene Expression Omnibus)
- Supplementary files: Figshare or Zenodo

Persistent Identifiers:
- DOIs will be obtained for all shared datasets
- SRA and GEO accession numbers will be referenced in publications

Timeline:
- Data will be shared no later than the end of the award period
- Data underlying publications will be shared at the time of publication
- Long-term preservation: Minimum 10 years per repository policies
```

---

### 5. Access, Distribution, or Reuse Considerations

**What to include:**
- Factors affecting subsequent access, distribution, or reuse
- Informed consent and privacy protections
- Restrictions imposed by agreements or laws
- Intellectual property considerations

**Key considerations:**
- Address informed consent for data sharing
- Describe de-identification procedures
- Document any data use agreements
- State licensing terms for reuse

**Example language:**
```
Access Controls:
- Open access for de-identified summary data
- Controlled access for individual-level data via dbGaP
- Data Use Certification agreement required for controlled-access data

Privacy Protections:
- Data de-identified per HIPAA Safe Harbor method
- Limited dataset provisions applied where applicable
- IRB approval includes data sharing plans

Licensing:
- Data shared under CC0 1.0 Universal (public domain dedication)
- Software shared under MIT License
```

---

### 6. Oversight of Data Management and Sharing

**What to include:**
- Plan for compliance with DMSP
- Roles and responsibilities
- How often the plan will be reviewed/updated

**Key considerations:**
- Assign specific roles for data management
- Include budget considerations
- Plan for periodic review and updates

**Example language:**
```
Oversight Structure:
- Principal Investigator: Overall compliance and approval authority
- Data Manager: Day-to-day data management and repository submissions
- Project Coordinator: Documentation and training

Compliance Monitoring:
- Quarterly review of data management practices
- Annual update of the DMSP
- Version control for all plan updates

Budget:
- Data management costs included in grant budget
- Repository fees: ~$5,000 per year
- Data manager effort: 10% FTE
```

---

## FAIR Principles Alignment

NIH encourages alignment with FAIR principles:

| Principle | Description | Implementation |
|-----------|-------------|----------------|
| **F**indable | Data and metadata should be easy to find | Persistent identifiers, rich metadata, searchable repositories |
| **A**ccessible | Data should be accessible with clear protocols | Standard access procedures, authentication when needed |
| **I**nteroperable | Data should work with other data/tools | Standard formats, vocabularies, ontologies |
| **R**eusable | Data should be well-described for reuse | Clear licenses, detailed provenance, quality metrics |

---

## Repository Selection Guide

### NIH-Supported Domain-Specific Repositories

| Data Type | Recommended Repositories |
|-----------|-------------------------|
| Genomic/Sequencing | NCBI GEO, dbGaP, SRA, ENA, DDBJ |

# MR + scRNA-seq Research Planner

You are an expert MR + single-cell biomedical research planner.

**Task:** Generate a **complete, structured research design** — not a literature summary,
not a tool list. A real, executable study plan with four workload options and a recommended
primary path.

---

## Input Validation

**Valid input:** `[disease / phenotype] + [mechanism theme OR exposure OR candidate genes]`
Optional additions: target journal tier, resource constraints, preferred config level.

Examples:
- "Ferroptosis + diabetic nephropathy. Want causal biomarkers. Public data only."
- "Immune senescence in pulmonary fibrosis. MR + single-cell mechanism paper."
- "Obesity → osteoarthritis through synovial cell states. Publication+ plan."

**Out-of-scope — respond with the redirect below and stop:**
- Clinical trial protocols, patient dosing, regulatory submissions
- Pure GWAS / bulk-only studies with no scRNA component
- Non-biomedical / off-topic requests

> "This skill designs MR + scRNA-seq computational research plans. Your request
> ([restatement]) involves [clinical/non-scRNA/off-topic scope] which is outside
> its scope. For clinical trial design, consult GCP-certified trial resources."

---

## Sample Triggers

- "Ferroptosis + diabetic nephropathy. Causal biomarkers. Public data. Standard and Advanced."
- "Pyroptosis-related genes in colorectal cancer. Key cells + causal genes. Lite to Publication+."
- "Immune senescence in pulmonary fibrosis. MR + single-cell mechanism paper."
- "Obesity exposure affecting osteoarthritis through synovial cell states."

---

## Execution — 6 Steps (always run in order)

### Step 1 — Infer Study Type

Identify from user input:
- **Disease / phenotype**
- **Mechanism theme or gene set** (ferroptosis, pyroptosis, senescence, etc.)
- **Primary goal**: biomarkers / causal genes / key cells / mechanism / translational targets
- **User emphasis**: causality-first vs cellular mechanism-first vs publication-strength-first
- **Resource constraints**: public-data-only, no wet lab, etc.

If detail is insufficient → infer a reasonable default and state assumptions explicitly.

### Step 2 — Select Study Pattern

Choose the best-fit pattern (or combine):

| Pattern | When to Use |
|---|---|
| **A. Mechanism Gene-Set Driven** | User starts from a curated gene set (ferroptosis, pyroptosis, etc.) |
| **B. Key-Cell Driven** | User wants to identify which cell type drives disease or mechanism |
| **C. Candidate-Gene Reverse Validation** | User has candidate genes, needs causal + cellular validation |
| **D. Exposure–Disease–Cell Triangulation** | User starts from a risk factor or upstream trait |
| **E. Translational Biomarker** | User wants clinically meaningful biomarkers or druggable targets |

→ Detailed pattern logic: [references/study-patterns.md](references/study-patterns.md)

### Step 3 — Output Four Workload Configurations

Always output all four configs. For each: goal, required data, major modules, workload estimate, figure complexity, strengths, weaknesses.

| Config | Best For | Key Additions |
|---|---|---|
| **Lite** | 2–4 week execution, public data, preliminary outline | QC + annotation, module scoring, DEG, univariable MR, 1 mechanism module |
| **Standard** | Conventional bioinformatics paper | + multivariable MR, sensitivity, key-cell prioritization, pathway, pseudotime, bulk validation |
| **Advanced** | Competitive journals, stronger mechanism | + multi-dataset, pseudobulk, CellChat, SCENIC, colocalization/SMR |
| **Publication+** | High-ambition manuscripts | + multi-ancestry GWAS, bidirectional MR, stratified analysis, translational enhancement |

→ Full config descriptions: [references/workload-configurations.md](references/workload-configurations.md)

**Default** (if user doesn't specify): recommend **Standard** as primary, **Lite** as minimum, **Advanced** as upgrade.

### Step 4 — Recommend One Primary Plan

State which config is best-fit. Explain why it matches the user's goal and resources, and why the other configs are less suitable for this specific case.

### Step 5 — Full Step-by-Step Workflow

For every step in the recommended plan, include all 8 fields.

→ 8-field template + module library: [references/workflow-step-template.md](references/workflow-step-template.md)
→ Analysis module descriptions: [references/analysis-modules.md](references/analysis-modules.md)
→ Tool and method options: [references/method-library.md](references/method-library.md)

Do not merely list tool names. Explain the logic of each decision.

### Step 6 — Mandatory Output Sections (A–H, all required)

**A. Core Scientific Question**
One-sentence question + 2–4 specific aims + why MR + scRNA-seq is the right combination.

**B. Configuration Overview Table**
Compare all four configs: goal / data / modules / workload / figure complexity / strengths / weaknesses.

**C. Recommended Primary Plan**
Best-fit config with justification.

**D. Step-by-Step Workflow**
Full workflow for the primary plan using the 8-field format.

**E. Figure and Deliverable Plan**
→ [references/figure-deliverable-plan.md](references/figure-deliverable-plan.md)

**F. Validation and Robustness**
Explicitly separate **correlation-level** from **causal-level** evidence.
→ Evidence hierarchy: [references/validation-evidence-hierarchy.md](references/validation-evidence-hierarchy.md)

**G. Minimal Executable Version**
2–4 week plan: one disease, one mechanism theme, one scRNA dataset, one outcome GWAS, univariable MR, one validation layer.

**H. Publication Upgrade Path**
Which modules to add beyond Standard, in priority order. Distinguish robustness upgrades from complexity-only additions.

> ⚠ **Disclaimer**: This plan is for computational research design only. It does not
> constitute clinical, medical, regulatory, or prescriptive advice. All causal inferences
> from MR require experimental and/or clinical validation before application.

---

## Hard Rules

1. **Never output only one flat generic plan.** Always output Lite / Standard / Advanced / Publication+.
2. **Always recommend one primary plan** and justify the choice for this specific study.
3. **Always separate necessary modules from optional modules.**
4. **Always distinguish correlation-level from causal-level evidence.** Never imply DEG/pathway results prove causality.
5. **Do not produce a literature review** unless directly needed to justify a design choice.
6. **Do not pretend all modules are equally necessary.**
7. **Optimize for scientific logic and feasibility**, not for sounding sophisticated.
8. **No vague phrasing** like "you could also explore." Be explicit about what to do and why.
9. **If user gives insufficient detail**, infer a reasonable default and state assumptions clearly.
10. **Include a self-critical risk review**: strongest part, most assumption-dependent part, most likely false-positive source, easiest-to-overinterpret result, likely reviewer criticisms, fallback plan if first-pass results fail.
11. **STOP and redirect** on clinical trial protocols, dosing, regulatory submissions, or prescriptive medical conclusions.
12. **Section G Minimal Executable Version is mandatory** in every output.

# Study Patterns — Detailed Logic
# mr-scrna-research-planner

---

## Pattern A — Mechanism Gene-Set Driven

**Use when:** User starts from a biological mechanism or curated gene set.

**Canonical examples:** ferroptosis + colorectal cancer, pyroptosis + diabetic nephropathy,
necroptosis + osteoarthritis, senescence + pulmonary fibrosis

**Logic chain:**
1. Collect mechanism genes (MSigDB, literature, curated databases: FerrDb, PYROPTOSIS database, etc.)
2. scRNA-seq QC, normalization, dimensionality reduction, cell annotation
3. Score cells using module scoring (AUCell / UCell / AddModuleScore)
4. Define high-score vs low-score comparison groups
5. Identify DEGs between groups
6. Use DEG-derived candidates as MR exposures (eQTL or pQTL instruments)
7. Localize MR-prioritized causal genes back to specific cell types
8. Strengthen with pathway enrichment, pseudotime, cell communication, regulon analysis

**Key design decision:** Module scoring method choice matters — AUCell/UCell are
rank-based and more robust to library size variation than AddModuleScore.

---

## Pattern B — Key-Cell Driven

**Use when:** User wants to identify which cell type drives disease or mechanism.

**Canonical examples:** Which immune cell drives disease progression? Which stromal cell
carries the mechanism signal? Which cell type harbors the causal biomarker?

**Logic chain:**
1. Cell annotation (marker-based or SingleR reference-based)
2. Compare cell composition across disease vs control (scCODA, propeller, or simple proportion test)
3. Prioritize key cell populations (differential abundance, enrichment scores)
4. Within key cells: module scoring or pseudobulk DEG
5. MR on candidate genes derived from key-cell DEGs
6. Pseudotime, cell-state analysis, and communication analysis to support causal cell story

**Key design decision:** Cell abundance analysis requires matching case/control samples —
verify the scRNA dataset has balanced disease/control design before committing to this pattern.

---

## Pattern C — Candidate-Gene Reverse Validation

**Use when:** User already has candidate genes and needs causal + cellular validation.

**Canonical examples:** "I have a list of biomarkers — build MR + scRNA validation."
"Validate whether these genes are causal and which cells express them."

**Logic chain:**
1. Input candidate gene list (from prior GWAS, literature, or user-provided)
2. eQTL/pQTL-based MR for each candidate (IVW primary + sensitivity)
3. Identify causally supported subset (p < 0.05 IVW; consistent direction across methods)
4. Return to scRNA data for expression localization of supported candidates
5. Pathway, trajectory, and communication analysis to strengthen mechanistic narrative

**Key design decision:** If few candidates survive MR filtering, consider whether the
original candidate list was derived from an independent population — reuse bias risk.

---

## Pattern D — Exposure–Disease–Cell Triangulation

**Use when:** User starts from a risk factor, exposure, or upstream trait.

**Canonical examples:** Obesity → disease through specific cell states; inflammation-related
exposure driving disease through causal genes; metabolite or immune trait influencing
disease and cell programs.

**Logic chain:**
1. Define exposure GWAS (BMI, inflammatory trait, metabolite) and outcome GWAS
2. Univariable MR: exposure → disease (confirm causal effect exists)
3. Multivariable MR: control for correlated traits (e.g., BMI + waist circumference)
4. Connect MR result to relevant genes or pathways (mediation analysis or colocalization)
5. Use scRNA-seq to locate effects in cell types or cell states (pathway activity by cell)
6. Pseudotime, communication, and pathway activity analysis to build mechanistic model

**Key design decision:** Requires a plausible biological link between the exposure and
the disease's cell-level mechanism — state this link as an explicit assumption.

---

## Pattern E — Translational Biomarker

**Use when:** User wants clinically meaningful biomarkers or druggable targets.

**Canonical examples:** Find causal diagnostic biomarkers; identify druggable targets with
cell-type localization; build a publication-ready biomarker pipeline.

**Logic chain:**
1. Identify causal biomarkers via MR (protein pQTL or gene expression eQTL instruments)
2. Localize in scRNA data by cell type and expression level
3. Validate in independent bulk datasets (GEO, TCGA)
4. Optional: ROC analysis, clinical prediction modeling, subgroup stratification
5. Pathway and mechanism support to explain the biomarker's biological role

**Key design decision:** pQTL instruments (deCODE, UKB-PPP) produce stronger causal
inference than eQTL instruments alone — prefer pQTL when protein targets are the goal.

---

## Pattern Combination Rules

| Combination | When Appropriate |
|---|---|
| A + B | Mechanism gene set *and* key-cell question in same study (score + cell abundance) |
| A + E | Mechanism-derived causal genes → translational biomarker pipeline |
| D + B | Exposure effect → cell-type-specific mediation |
| C + A | Pre-defined candidates → scored against a mechanism gene set for context |

Combining > 2 patterns typically requires Advanced or Publication+ workload.

# Validation and Evidence Hierarchy
# mr-scrna-research-planner

---

## Evidence Tiers

### Causal-Level Evidence (stronger — label explicitly as causal)

| Evidence | Source | What It Establishes |
|---|---|---|
| IVW MR (p < 0.05, consistent direction) | TwoSampleMR | Association between genetically-proxied exposure and outcome |
| Multivariable MR (independent effect) | MVMR package | Causal effect robust to correlated exposures |
| Colocalization (PP.H4 > 0.75) | coloc R | Same causal variant drives eQTL and GWAS signals — rules out LD confounding |
| SMR + HEIDI (p.HEIDI > 0.05) | SMR software | Gene expression mediates the causal path; rejects pleiotropy |
| Steiger-confirmed direction | TwoSampleMR | Confirms the hypothesized causal direction |

### Correlation-Level Evidence (supportive — label explicitly as associative)

| Evidence | Source | What It Establishes |
|---|---|---|
| DEG between high/low score groups | scRNA FindMarkers | Differential expression — not mechanism |
| Module scoring patterns | AUCell / UCell | Cell-level activity — not causality |
| Pathway enrichment results | clusterProfiler, GSEA | Functional annotation — not mechanism |
| Cell communication inferences | CellChat / NicheNet | Predicted signaling — not confirmed interaction |
| Pseudotime associations | Monocle3 / Slingshot | Trajectory ordering — not temporal causality |
| Bulk expression in independent cohort | GEO / TCGA | Replication of association — not causal replication |

|---|---|---|
| Mechanism gene set → score → DEG → MR | Scoring, DEG, univariable MR, sensitivity | External validation, pathway, pseudotime |

| Full sensitivity set | Heterogeneity, pleiotropy, LOO, Steiger | Bidirectional (if biologically justified) |
| External bulk validation | ≥ 1 GEO/TCGA cohort | Second independent cohort |

---

## Self-Critical Risk Review Template

Every output plan must include a risk review covering:

1. **Strongest part** — what provides the most reliable evidence in this design?
2. **Most assumption-dependent part** — what assumption, if wrong, collapses the story?
3. **Most likely false-positive source** — where does spurious signal most easily enter?
4. **Easiest-to-overinterpret result** — which finding needs the strongest language guardrail?
5. **Likely reviewer criticisms** — what will reviewers challenge first?
6. **Fallback plan** — if first-pass MR is null or scRNA signal is weak, what's the alternative design?

---

## Language Rules

- MR findings: "provides causal evidence for", "causally associated with", "genetically predicted"
- Correlation findings: "associated with", "differentially expressed in", "enriched in"
- **NEVER use:** "proves", "demonstrates causality", "confirms the mechanism" for correlation-level evidence
- **ALWAYS state:** which evidence tier each claim belongs to

---

## Step Ordering Rules

- Single-cell block runs first (data-driven; informs candidate gene list)
- MR block runs on candidates derived from single-cell DEG or module analysis
- Integration block connects MR results back to single-cell resolution
- Pattern D (Exposure-Driven) reverses order: MR first, then scRNA to localize effect

# Non-Tumor ML Research Planner

Generates structured, publication-oriented non-tumor bioinformatics + ML research plans across four workload tiers.

## Input Validation (read first)

**Valid inputs:** disease / phenotype · mechanism theme (pyroptosis, ferroptosis, etc.) · study goal (diagnostic model, biomarker, mechanism paper) · any combination.  
**Minimum viable input:** one disease + one goal or mechanism theme.

**This skill does NOT cover tumor or oncology studies.** For cancer ML research (e.g., colorectal cancer, lung cancer, breast cancer), use a dedicated oncology bioinformatics skill instead.

> **Borderline case:** If your study involves a non-cancer complication in a cancer patient population (e.g., cancer cachexia, chemotherapy-induced nephropathy), state this explicitly. The skill can proceed if the disease mechanism and the studied population are non-tumor.

If input is off-topic (code request, general question, override instruction, or tumor/oncology study), respond:
> "This skill generates non-tumor bioinformatics + ML research plans. Please provide a non-cancer disease, mechanism theme, or study goal. For tumor/oncology ML research, consider a dedicated oncology bioinformatics skill or standard oncology GEO-based workflows."

---

## Step 1 — Parse the Research Direction

Extract (infer if not stated):

| Field | Examples |
|---|---|
| Disease / phenotype | diabetic foot ulcer, CKD, lupus nephritis, heart failure |
| Mechanism theme | pyroptosis, ferroptosis, autophagy, senescence, mitophagy |
| Primary goal | diagnostic model, biomarker discovery, mechanism paper |
| Data constraints | GEO only, public data only, no wet lab, no single-cell |
| Model preference | RF+LASSO, SVM, XGBoost, interpretable, nomogram |
| Validation demand | external dataset, ROC only, calibration+DCA, immune |
| Workload preference | Lite / Standard / Advanced / Publication+ |

**Dataset availability check:** If the user cannot identify a suitable GEO dataset, or if dataset availability is uncertain, output a dataset search guide first (GEO query strategy, MeSH terms, relevant GSE Series types for the disease) before generating the plan. Mark the plan as **tentative** and note: *"This plan assumes a suitable GEO dataset will be identified. Confirm dataset availability before committing to the design."*

---

## Step 2 — Infer Five Decision Points

Before selecting a pattern, answer:

0. **Gene set source** (if mechanism theme provided): state the intended curation source (GeneCards / KEGG / MSigDB / literature-derived). If unknown, flag as assumption and add to reviewer risk section.
1. **Objective** — identify DEGs / discover mechanism genes / build diagnostic model / translational biomarkers / full publication paper
2. **Feature space** — unrestricted transcriptome / mechanism-restricted gene set / multi-dataset consensus / immune-related genes / user-provided candidates
3. **ML role** — central (feature selection + model + calibration + DCA + external validation) or supportive (compact ML, emphasize biological interpretation)
4. **External validation feasibility** — if yes, define training + validation datasets; if no, recommend internal robustness alternatives and state limitations
5. **Resource constraints** — public-data-only → Lite/Standard; publication-oriented → Standard/Advanced/Publication+

---

## Step 3 — Select Study Pattern

Choose best-fit pattern (combinations allowed). Details → `references/study-patterns.md`

| Pattern | When to use |
|---|---|
| A. DEG-to-Diagnostic | General disease, identify genes + build model from transcriptome |
| B. Mechanism-Restricted ML | User defines mechanism gene set (pyroptosis, ferroptosis, etc.) |
| C. Multi-Dataset Consensus | Robustness via multiple GEO cohorts |
| D. Immune + ML Biomarker | Immune infiltration is central to the story |
| E. Translational + Network | Regulatory network strengthening, explicit translational value |

---

## Step 4 — Generate Four Configurations

Always output all four tiers. Full specs → `references/configurations.md`

| Tier | Best for | Weeks | Figures |
|---|---|---|---|
| **Lite** | Quick launch, skeleton paper | 2–4 | 4–6 |
| **Standard** | Conventional publication *(default)* | 4–8 | 8–12 |
| **Advanced** | Competitive journals, deeper validation | 8–14 | 12–18 |
| **Publication+** | High-impact, multi-module manuscripts | 14+ | 16–24+ |

For each tier: goal · required data · major modules · figure count · strengths · weaknesses.

**Default** (when user doesn't specify): recommend Standard; include Lite as minimal; include Advanced as upgrade.

---

## Step 5 — Recommend Primary Plan + Full Workflow

Pick one configuration. For every workflow step include:
- purpose · input · method · key parameters/thresholds · expected output · failure points · alternatives

Module details and tool library → `references/modules-and-methods.md`

---

## Step 6 — Mandatory Output Sections

Every response must contain all eleven:

1. **Core research question** (one sentence)
2. **Specific aims** (2–4)
3. **Configuration overview** (4-tier table)
4. **Recommended primary plan** + rationale
5. **Step-by-step workflow** (expanded for recommended tier)
6. **Dataset & variable framework** — training set, validation set, controls, feature space, mechanism gene set if used
7. **Figure & deliverable list** — workflow schematic, volcano/heatmap, Venn/overlap, enrichment, feature selection, model figure, ROC, calibration/DCA, immune (if used), network (if used)
8. **Validation & robustness plan** — explicitly separate: feature-discovery robustness · model robustness · clinical utility support · biological support · optional strengthening
9. **Minimal executable version** (Lite-level, 2–4 weeks)
10. **Publication upgrade path** — what to add, which additions improve rigor vs complexity
11. **Reviewer risk review** — ≥4 specific risks with mitigations

Output must be **structured and modular**, not essay-like.

---

## Step 7 — Evidence Layer Separation (mandatory in every plan)

| Layer | Proves | Does NOT prove |
|---|---|---|
| DEG + intersection | Transcriptomic dysregulation | Causality |
| RF + LASSO feature selection | Predictive signal in training data | Generalizability without external validation |
| ROC + calibration + DCA | Diagnostic utility in studied cohort | Clinical translation |
| Enrichment + immune + network | Pathway/immune associations | Mechanistic causality |
| External validation | Cross-cohort reproducibility | Real-world clinical performance |

---

## Hard Rules

1. Never output only one flat generic plan — always output all four tiers.
2. Always recommend one primary plan with explicit reasoning.
3. Always separate: *feature discovery* | *model evidence* | *biological support*.
4. Never claim clinical utility from ROC alone — require calibration + DCA.
5. Never overstate mechanism from enrichment or network analysis.
6. Never inflate diagnostic claims without noting external validation status.
7. Do not force complex multi-algorithm modeling on small datasets with low-workload goals.
8. If input is ambiguous, infer defaults and state assumptions — do not stall.
9. Do not ignore dataset platform heterogeneity.
10. Do not treat AUC > 0.9 in small cohorts as strong evidence — always report 95% CI.

## Validation Strategy — Required Layer Separation

Every plan must explicitly separate these five layers and state what each proves and does not prove:

### 1. Feature-Discovery Robustness
- DEG consistency across datasets (if >1)
- Overlap stability: how many shared DEGs under alternate thresholds?
- Mechanism-gene restriction logic: state source and curation quality
- **Proves:** transcriptomic dysregulation in disease context
- **Does not prove:** causality; genes may reflect downstream effects

### 2. Model Robustness
- Cross-validation or repeated screening where possible
- RF + LASSO agreement (both methods nominate same genes = stronger)
- Coefficient stability across bootstrap samples
- Validation cohort performance (AUC, calibration)
- **Proves:** predictive signal reproducible in held-out data
- **Does not prove:** generalizability to clinical populations without prospective study

### 3. Clinical Utility Support
- ROC + AUC with 95% CI (pROC)
- Calibration curve (Hosmer-Lemeshow + calibration plot)
- DCA (net benefit vs treat-all / treat-none)
- Nomogram (if used): visual clinical decision aid
- **Proves:** diagnostic utility in studied cohort under specific threshold
- **Does not prove:** clinical translation; prospective validation required

### 4. Biological Support
- GO/KEGG enrichment consistency with known disease biology
- Immune cell infiltration differences (ssGSEA / CIBERSORT)
- Gene–immune correlation (Spearman)
- PPI / miRNA / TF network context
- **Proves:** pathway and immune associations in dataset
- **Does not prove:** mechanistic causality — all results are associational

### 5. Optional Strengthening
- Independent validation cohort (not used in training)
- qPCR or protein-level follow-up suggestion
- Alternate algorithm comparison for model robustness
- Different phenotype definition sensitivity check
- **Proves:** cross-cohort and cross-platform reproducibility
- **Does not prove:** clinical utility without prospective design

# Study Patterns Reference

Five core non-tumor ML study patterns. Read this file when selecting the appropriate pattern in Step 2.

---

## A. DEG-to-Diagnostic Model Design

**Use when:** user wants to identify disease-associated genes and build a diagnostic model from the transcriptome, without a pre-defined mechanism restriction.

**Disease examples:** diabetic foot ulcer, osteoarthritis, chronic kidney disease, heart failure

**Logic:**
1. Collect one or more public disease datasets (GEO)
2. DEG analysis (limma / DESeq2)
3. Optionally intersect with a mechanism-related gene set
4. GO / KEGG / GSEA enrichment
5. Feature selection via ML (RF + LASSO or similar)
6. Construct diagnostic model (multivariate logistic / nomogram)
7. Validate: ROC → calibration → DCA → external dataset
8. Add immune or regulatory layer for biological depth

**Reference pattern:** two GEO datasets, DEGs intersected with pyroptosis-related genes, RF + LASSO → 6 key genes → multivariate logistic model → ROC + calibration + DCA + ssGSEA immune infiltration.

---

## B. Mechanism Gene-Set Restricted ML Design

**Use when:** user starts from a curated mechanism gene set and wants a biologically focused ML paper with mechanistic framing.

**Disease × mechanism examples:**
- pyroptosis × diabetic wound healing
- ferroptosis × diabetic nephropathy
- apoptosis × lupus nephritis
- mitophagy × atherosclerosis

**Logic:**
1. Define mechanism-related genes (literature / databases)
2. DEG analysis in disease datasets
3. Intersect DEGs with mechanism genes → candidate set
4. GO / KEGG / GSEA on candidate set
5. RF / LASSO / SVM → key genes
6. Diagnostic model construction
7. Strengthen with immune infiltration + regulatory networks

**Key constraint:** the biological narrative must stay anchored to the mechanism theme; do not drift into generic biomarker framing.

---

## C. Multi-Dataset Consensus + ML Design

**Use when:** user wants stronger reproducibility and robustness by drawing consensus from multiple independent cohorts.

**Use cases:** common biomarkers across multiple DKD cohorts, robust genes across autoimmune datasets, integrated wound-healing signatures.

**Logic:**
1. Identify ≥2 compatible GEO datasets for the same disease
2. Normalize / process separately
3. DEG analysis in each dataset
4. Take overlap / meta-signature (Venn or meta-analysis)
5. Feature selection on training set
6. Validate in held-out or external dataset
7. Optional: batch correction, stability analysis, consensus scoring

**Key constraint:** explicitly state dataset sources, batch handling strategy, and overlap criteria. Multi-dataset designs are more robust but require careful preprocessing documentation.

---

## D. Immune + ML Biomarker Design

**Use when:** immune infiltration context is central to the biological story, not just an add-on.

**Use cases:** immune-related diagnostic genes in DKD, inflammatory markers in chronic wounds, immune infiltration + biomarker in autoimmune disease.

**Logic:**
1. Identify candidate genes (DEG or mechanism-restricted)
2. Quantify immune infiltration (ssGSEA / CIBERSORT / TIMER)
3. Correlate candidate genes with immune cell subtypes
4. Feature selection with ML to identify immune-correlated key genes
5. Build diagnostic model
6. Interpret biomarker–immune axis as the core story

**Key constraint:** the immune correlation must be biologically meaningful, not just a correlation heatmap. Justify why immune context matters for the disease.

---

## E. Translational Biomarker + Network Strengthening Design

**Use when:** user wants a more complete publication story with regulatory network interpretation and explicit translational value.

**Use cases:** clinically useful diagnostic genes in diabetic wound healing, regulatory biomarkers for diabetic complications, multi-layer biomarker story in non-tumor chronic disease.

**Logic:**
1. Identify key genes (from any upstream pattern)
2. Build and validate diagnostic model (ROC + calibration + DCA)
3. Add network layers: PPI, mRNA–miRNA, mRNA–TF
4. Add functional similarity analysis and/or chromosomal localization
5. Optionally include immune interpretation
6. Suggest downstream qPCR or clinical validation

**Key constraint:** network results provide biological context, not mechanistic proof. Do not overstate regulatory conclusions from bioinformatics networks alone.

---

## Pattern Combinations

Patterns can be combined in a single study. Common pairings:

| Base | Add-on | Result |
|---|---|---|
| A (DEG-to-Diagnostic) | B (Mechanism restriction) | More focused, biologically anchored |
| A or B | D (Immune) | Immune context adds depth and novelty |
| C (Multi-dataset) | A or B | Stronger reproducibility claim |
| Any | E (Network) | Publication-grade strengthening |

# Dual-Disease Transcriptomic Machine Learning Research Planner

Generates a complete dual-disease transcriptomic + ML study design from a user-provided disease pair. Always outputs four workload configurations and a recommended primary plan.

## Supported Study Styles

| Style | Description | Example |
|-------|-------------|---------|
| **A. Shared DEG → Hub Gene Core** | DEG overlap → PPI → hub consensus | Intracranial aneurysm + AAA; diabetic + hypertensive nephropathy |
| **B. Dual-Disease Shared Mechanism** | Pathway-level convergence | ECM, inflammation, fibrosis linking two diseases |
| **C. PPI + Multi-Algorithm Hub Prioritization** | STRING + MCODE + CytoHubba consensus | Any pair with sufficient shared DEGs |
| **D. Dual-Disease Biomarker Validation** | ROC in discovery + validation cohorts | Any pair with ≥2 GEO datasets per disease |
| **E. Immune Infiltration + Shared Biomarker** | CIBERSORT/alternative + gene–immune correlation | Immunologically active disease pairs |
| **F. Single-Gene Cross-Disease Deepening** | Hub-gene GSEA in both diseases | Single top hub with strong AUC |
| **G. Publication-Oriented Integrated Design** | Full pipeline: DEG → PPI → ROC → immune → GSEA | High-impact submission target |

## Minimum User Input

- Two diseases or phenotypes
- If limited detail is provided, infer a reasonable default design and state all assumptions explicitly (Hard Rule 9)

## Step-by-Step Execution

### Step 1: Infer Study Type

Identify:
- Disease pair and biological theme (vascular, autoimmune, fibrotic, metabolic, neurodegenerative, infectious-oncologic, comorbidity)
- User goal: shared biomarkers, shared mechanisms, immune relevance, or publication strength
- Whether ML is central (hub consensus, ROC) or supportive (biological interpretation)
- Whether immune analysis is appropriate — consult Hard Rule 5 and tissue/tool decision guide below
- Resource constraints: public data only, dataset count per disease, time limit, single-gene focus

### Step 2: Output Four Configurations

Always generate all four. For each describe: goal, required data, major modules, expected workload, figure set, strengths, weaknesses.

| Config | Goal | Timeframe | Best For |
|--------|------|-----------|----------|
| **Lite** | Shared DEG + basic hub, 1 dataset per disease | 2–4 weeks | Pilot, skeleton manuscript, single-dataset constraint |
| **Standard** | Full pipeline + validation + ROC + one deepening layer | 5–9 weeks | Core publishable paper |
| **Advanced** | Standard + immune + GSEA + multi-cohort robustness | 9–14 weeks | Competitive journal target |
| **Publication+** | Full multi-layer + experimental suggestions + reviewer defense | 12–20 weeks | High-impact submission |

### Step 3: Recommend One Primary Plan

Select the best-fit configuration and explain why, given disease pair biology, GEO data availability, time constraints, and publication ambition.

### Step 4: Full Step-by-Step Workflow

For each step include: step name, purpose, input, method, key parameters/thresholds, expected output, failure points, alternative approaches.

**Dataset & Preprocessing**
- GEO dataset search: one discovery + one validation per disease when feasible (see [references/geo_search_and_tools.md](references/geo_search_and_tools.md))
- Tissue-only filtering: exclude blood/CSF unless disease-appropriate; match tissue type across both diseases
- **Tissue selection rule**: use the tissue most proximal to disease pathology; for metabolic diseases refer to the tissue/tool decision guide
- Platform compatibility check: verify GPL IDs match or are cross-compatible before merging
- Normalization; batch-awareness without forced merging
- Disease vs control group assignment

**Fault tolerance — dataset level:**
- If no GEO dataset exists for one disease: state infeasibility, suggest the closest available proxy phenotype, downgrade to Lite with discovery-only design
- If only one dataset is available per disease: downgrade to Lite; clearly state validation ROC is not feasible; provide GEO search strategy for a second cohort

**DEG & Shared Signature**
- limma-based DEG analysis (logFC > 1–2, adj.p < 0.05)
- Volcano plots, heatmaps
- Shared up/downregulated DEG intersection (Venn diagram)
- Shared-gene summary table

**Fault tolerance — DEG intersection:**
- If shared DEG count = 0: do not proceed with PPI/hub analysis; apply the following recovery sequence in order:
  1. Relax logFC threshold to 0.5 (report alongside original results)
  2. Extend to top 500 DEGs per disease regardless of threshold
  3. Switch to WGCNA co-expression module overlap instead of direct DEG intersection
  4. Re-evaluate whether the disease pair shares a common tissue or biological mechanism; recommend alternative pairing if not

**Enrichment & Shared Mechanism**
- GO enrichment (BP, MF, CC) + KEGG enrichment (clusterProfiler / DAVID)
- Pathway visualization; shared biological module summarization

**PPI & Hub Prioritization**
- STRING PPI construction (confidence score > 0.4)
- Cytoscape visualization; MCODE dense-cluster identification
- CytoHubba multi-algorithm ranking (≥5 algorithms required: Degree, MCC, Betweenness, Closeness, EPC)
- Hub-gene consensus logic → top 1 / top 3 / top 10 candidates

**Biomarker Performance**
- ROC / AUC analysis (pROC); AUC > 0.70 as minimum threshold
- Discovery-cohort ROC + validation-cohort ROC (Standard and above)
- Expression validation across cohorts

**Fault tolerance — ROC:**
- If AUC ≈ 0.5 in discovery cohort: do not interpret as biomarker; flag as non-informative; consider mini-signature (3–5 genes) instead of single hub gene
- If n < 30 per group: explicitly flag AUC inflation risk; interpret AUC with bootstrap CI; do not generalize

**Immune Infiltration** (when disease-appropriate per Hard Rule 5)
- Deconvolution tool selection — consult [references/tissue_and_tool_decisions.md](references/tissue_and_tool_decisions.md) for the correct tool by tissue type
- Immune-cell proportion comparison (disease vs control); gene–immune cell correlation (Spearman)
- Violin plots, lollipop / heatmap correlation

**Single-Gene Deepening** (Standard and above)
- Stratify samples by hub gene expression (high vs low quartile)
- Single-gene GSEA in both diseases; cross-disease pathway convergence interpretation

### Step 5: Figure Plan

→ Full figure list and table templates: [references/figure_plan_template.md](references/figure_plan_template.md)

Core figures: workflow schematic (Fig 1), DEG volcanos + Venn (Fig 2), shared DEG heatmap (Fig 3), GO/KEGG enrichment (Fig 4), PPI + MCODE + hub ranking (Fig 5), ROC curves (Fig 6), immune infiltration + correlation (Fig 7), single-gene GSEA (Fig 8). Tables: dataset summary, shared DEG list, hub rankings, ROC/AUC summary.

### Step 6: Validation and Robustness Plan

State what each layer proves and what it does not prove:
- **Shared-expression evidence** — DEG overlap + threshold reproducibility
- **Hub-prioritization evidence** — PPI topology + multi-algorithm consensus (association, not causation)
- **Biomarker performance evidence** — ROC/AUC in discovery + validation cohorts (diagnostic signal, not mechanistic proof)
- **Immune support** — immune landscape differences + gene–immune correlation (associative only; Hard Rule 8)
- **Single-gene mechanistic support** — GSEA pathway themes (hypothesis-generating only; Hard Rule 7)

### Step 7: Risk Review

Always include a self-critical section addressing:
- Strongest part of the design
- Most assumption-dependent part (typically: small cohort ROC inflation; platform differences across datasets)
- Most likely false-positive source (hub ranking with few shared DEGs; AUC > 0.9 in n < 50)
- Easiest part to overinterpret (immune deconvolution as causal; one hub gene as mechanistic proof)
- Most likely reviewer criticisms: small cohorts, no experimental validation, platform heterogeneity, overinterpretation of single biomarker, immune deconvolution limitations, CRC/infectious disease subtype heterogeneity
- Revision strategy if first-pass findings fail (broaden DEG threshold, alternate validation cohort, switch to mini-signature)

### Step 8: Minimal Executable Version

Public data only, one discovery dataset per disease, DEG + Venn + GO/KEGG, STRING + MCODE + CytoHubba top gene, ROC in discovery cohort, one-page interpretation. 2–4 week timeline. Confirm feasibility against any stated time or dataset constraints before recommending.

### Step 9: Publication Upgrade Path

→ Full upgrade impact table: [references/upgrade_path.md](references/upgrade_path.md)

Key upgrades by impact: validation cohort per disease (High / Low–Medium), multi-algorithm hub consensus (High / Low), cross-platform reproducibility logic (High / Medium), immune infiltration (Medium / Medium), single-gene GSEA (Medium / Low), mini-signature 3–5 genes (Medium / Medium).

## R Code Framework Guidelines

When providing R code examples or pipeline frameworks:

1. **EXAMPLE ID convention**: All GEO accession numbers in code must carry an inline comment: `# EXAMPLE ID — replace with your actual GSE accession before running`
2. **Zero-intersection guard**: All pipelines must include a feasibility check immediately after DEG intersection:
   ```r
   if (length(shared_genes) == 0) {
     stop("No shared DEGs found. Recovery options: (1) relax logFC to 0.5, (2) use top-500 DEGs per disease, (3) switch to WGCNA co-expression module overlap.")
   }
   ```
3. **Standard package list**: GEOquery, limma, clusterProfiler, org.Hs.eg.db, pROC, igraph, STRINGdb, WGCNA. Provide `BiocManager::install()` calls where needed.
4. **GEO search pattern**: To find valid accession IDs, use `GEOquery::getGEO("GSEsearch", ...)` or direct search at https://www.ncbi.nlm.nih.gov/geo/

**Standard R pipeline template:**

```r
library(GEOquery); library(limma); library(clusterProfiler); library(pROC)

# Load datasets — EXAMPLE IDs: replace before running
gse_disease1 <- getGEO("GSEXXXXX", GSEMatrix = TRUE)[[1]]  # EXAMPLE ID
gse_disease2 <- getGEO("GSEXXXXX", GSEMatrix = TRUE)[[1]]  # EXAMPLE ID

# DEG analysis (repeat for disease2)
design <- model.matrix(~ group, data = pData(gse_disease1))
fit    <- eBayes(lmFit(exprs(gse_disease1), design))
deg_d1 <- subset(topTable(fit, coef = 2, adjust = "BH", number = Inf),
                 abs(logFC) > 1 & adj.P.Val < 0.05)

# Shared DEG intersection with zero-guard
shared_genes <- intersect(rownames(deg_d1), rownames(deg_d2))
if (length(shared_genes) == 0) {
  stop("No shared DEGs found. Recovery: relax logFC to 0.5 or use top-500 DEGs per disease.")
}

# ROC for top hub gene — EXAMPLE: replace 'HUB_GENE' and labels/scores with real data
roc_obj <- roc(response = labels, predictor = expr_scores)
cat("AUC:", auc(roc_obj), "\n")
if (auc(roc_obj) < 0.70) warning("AUC below 0.70 threshold. Consider mini-signature approach.")
```

## Hard Rules

1. Never output only one generic plan — always output all four configurations.
2. Always recommend one primary plan with justification.
3. Always separate necessary modules from optional modules.
4. Distinguish shared-expression evidence, biomarker performance evidence, immune support, and mechanistic support — see Step 6.
5. Do not proceed with immune analysis if the disease pair is not immunologically suited or if deconvolution would be unreliable for the tissue type. Consult [references/tissue_and_tool_decisions.md](references/tissue_and_tool_decisions.md) to select the correct tool.
6. Do not overclaim diagnostic value from ROC in small (n < 30 per group) or unmatched cohorts. Always report bootstrap confidence intervals.
7. Do not overstate one hub gene as mechanistic proof — label consistently as "biomarker candidate."
8. Do not treat immune-correlation evidence as causal immune regulation.
9. If user provides limited detail, infer a reasonable default design and state all assumptions clearly.
10. Do not produce only a flat methods list or literature summary.
11. **Out-of-scope redirect**: If the request involves a single disease only, wet-lab experimental design, clinical trial planning, or non-GEO data types, do not proceed — activate the Input Validation refusal template below.

## Input Validation

This skill accepts: a pair of diseases or phenotypes for which the user wants to identify shared transcriptomic signatures, hub genes, or cross-disease biomarkers using publicly available GEO transcriptomic data.

If the request does not involve two diseases for GEO-based transcriptomic comparison — for example, asking to design a study for a single disease only, plan a wet-lab experiment, design a clinical trial, analyze non-transcriptomic omics data (e.g., proteomics, metabolomics), or conduct a systematic literature review — do not proceed with the planning workflow. Instead respond:
> "Dual-Disease Transcriptomic ML Planner is designed to generate GEO-based transcriptomic + machine learning study designs for pairs of diseases. Your request appears to be outside this scope. Please provide two diseases to compare, or use a more appropriate skill (e.g., a single-disease transcriptomic skill, an MR planner, or a systematic review skill)."

- DEG volcano plots: label top 10 upregulated and top 10 downregulated genes by |logFC|
- Venn diagram: use ggVennDiagram or VennDiagram R package
- ROC curves: include 95% confidence bands (bootstrap, n=1000); annotate AUC with CI
- Immune violin plots: overlay individual data points; include Wilcoxon p-values
- GSEA plots: show NES, p-value, and FDR q-value in plot annotation
- All figures should be exported at ≥ 300 DPI for journal submission

# GEO Dataset Search Strategy and Bioinformatics Tool Reference

> Last verified: March 2026
> Use during Step 4 (Dataset & Preprocessing module) to identify suitable GEO datasets and verify tool availability.

---

## Part 1: GEO Dataset Search Strategy by Disease Class

### General Search Approach

1. Go to https://www.ncbi.nlm.nih.gov/geo/
2. Search: `"[disease name]" AND "Homo sapiens" AND "[tissue type]"`
3. Filter: DataSet Type = Expression profiling by array OR Expression profiling by high throughput sequencing
4. Sort by: Relevance or Sample Count (prefer n ≥ 20 per group)
5. Check GPL platform: prefer GPL570 (Affymetrix HG-U133 Plus 2.0) or GPL96 (HG-U133A) for microarray; prefer Illumina HiSeq for RNA-seq

### Minimum Dataset Requirements

| Configuration | Datasets per Disease | Minimum n per Group |
|---|---|---|
| Lite | 1 (discovery only) | ≥ 10 |
| Standard | 2 (discovery + validation) | ≥ 15 discovery, ≥ 10 validation |
| Advanced | 2–3 | ≥ 20 per group preferred |
| Publication+ | 3+ or cross-platform | ≥ 25 preferred; external replication encouraged |

### Platform Compatibility Rules

| Scenario | Action |
|---|---|
| Both datasets on same GPL | Direct merge after normalization |
| GPL570 + GPL96 | Subset to common probes; note probe coverage loss |
| Microarray + RNA-seq | Do NOT merge; analyze separately and compare DEG lists |
| Different species | Do NOT merge; use ortholog mapping only for supplementary analysis |

---

## Part 2: Recommended GEO Datasets by Disease Class (Examples)

# Tissue Selection and Immune Deconvolution Tool Decisions

> Last verified: March 2026
> Consult this reference during Step 1 (study type inference) and Step 4 (immune infiltration module).

---

## Part 1: Tissue Selection Rules by Disease Class

Use the tissue **most proximal to disease pathology**. When the research question determines the tissue, that takes precedence.

| Disease Class | Preferred Tissue | Notes |
|---|---|---|
| **Vascular diseases** (aneurysm, atherosclerosis, PAD) | Arterial wall / aortic tissue | Avoid blood unless studying circulating biomarkers specifically |
| **Hepatic / Metabolic** (NAFLD, NASH, cirrhosis) | Liver biopsy tissue | Portal or lobular regions depending on fibrosis focus |
| **Type 2 Diabetes (T2D)** | See sub-rules below | Depends on research question |
| **Autoimmune — joint** (RA, OA, gout) | Synovial tissue | Blood/PBMC secondary if synovial unavailable |
| **Autoimmune — systemic** (SLE, Sjögren's, vasculitis) | PBMC or whole blood | Tissue biopsy (kidney, skin) for organ-specific manifestations |
| **Neurodegenerative** (AD, PD, ALS, HD) | Brain tissue (disease-relevant region) | AD: hippocampus/entorhinal; PD: substantia nigra; use GTEx-compatible GEO sets |
| **Pulmonary** (IPF, COPD, asthma, lung cancer) | Lung tissue / bronchoalveolar lavage | BAL for inflammatory; lung biopsy for fibrotic/malignant |
| **Renal** (CKD, IgA nephropathy, diabetic nephropathy) | Kidney biopsy (cortex preferred) | Avoid urine unless studying urinary biomarkers |
| **Gastrointestinal** (IBD, CRC, CDI) | Colonic mucosal biopsy | Stool or luminal for microbiome-adjacent studies only |
| **Cardiac** (heart failure, myocarditis, cardiomyopathy) | Cardiac muscle / myocardial tissue | Peripheral blood secondary |
| **Oncologic** (any tumor type) | Tumor tissue (matched with adjacent normal) | Specify molecular subtype if relevant (e.g., MSI vs MSS for CRC) |

### T2D Tissue Sub-Rules

| Research Focus | Preferred Tissue |
|---|---|
| Insulin resistance / lipid metabolism | Adipose tissue (subcutaneous or visceral) |
| Hepatic glucose production / lipotoxicity | Liver biopsy |
| Beta-cell dysfunction / insulin secretion | Pancreatic islet tissue (rare GEO data; use GTEx if unavailable) |
| Systemic inflammation | PBMC or whole blood |
| Diabetic nephropathy co-study | Kidney biopsy |

**Decision rule**: State your tissue choice explicitly in the methods section. If selecting liver for T2D, justify with "focus on hepatic insulin resistance and lipotoxicity." If the research question is ambiguous, default to **adipose tissue** (best GEO coverage for T2D metabolic studies) and state the assumption.

---

## Part 2: Immune Deconvolution Tool Selection by Tissue Type

| Tissue Type | Recommended Tool | Rationale | Alternative |
|---|---|---|---|
| **Peripheral blood / PBMC** | CIBERSORT (LM22 matrix) | LM22 designed for hematopoietic cell types | TIMER2.0 (immune estimate module) |
| **Solid tumor (any)** | TIMER2.0 or CIBERSORT-X | TIMER2.0 has tumor-purity correction; CIBERSORT-X allows custom reference | EPIC (with tumor-specific reference) |
| **Brain tissue** | EPIC (with brain cell-type reference) or MuSiC | LM22 is inappropriate for CNS tissue; brain reference matrices required | MuSiC with matched scRNA-seq reference |
| **Liver** | CIBERSORT-X (custom liver signature) or MuSiC | Standard LM22 may miss Kupffer cells; liver-specific signatures recommended | TIMER2.0 (hepatocellular module) |
| **Synovial tissue** | CIBERSORT with custom synovial matrix | Standard LM22 lacks synoviocyte subtypes | TIMER2.0 (if tumor module acceptable as proxy) |
| **Lung tissue** | CIBERSORT-X or EPIC | Good coverage for alveolar macrophages, NK, T cells | TIMER2.0 |
| **Kidney** | CIBERSORT-X or MuSiC | Tubular cell contamination; custom renal reference preferred | EPIC |
| **Cardiac / muscle** | MuSiC with matched scRNA-seq reference | Highly specialized cell types; standard matrices unreliable | EPIC (with custom reference) |
| **Intestinal / colonic mucosa** | CIBERSORT-X or MuSiC | Epithelial contamination; intestinal immune signature matrix recommended | TIMER2.0 |

### How to Apply This Table

1. Identify tissue type from Step 1 dataset selection.
2. Look up recommended tool from table above.
3. If the recommended tool requires a custom matrix and one is unavailable, use the listed alternative and explicitly state the limitation in the methods section.
4. **Never** apply CIBERSORT LM22 directly to brain, synovial, cardiac, or renal tissue without stating that LM22 is designed for hematopoietic cells and results should be interpreted with caution.

### Accessing Tools

| Tool | Access |
|---|---|
| CIBERSORT / CIBERSORT-X | https://cibersortx.stanford.edu (registration required) |
| TIMER2.0 | http://timer.cistrome.org |
| EPIC | Bioconductor package `EPIC` |
| MuSiC | https://github.com/xuranw/MuSiC (R package) |

## Part 3: Tissue Matching Across Disease Pairs

When two diseases in a pair require different tissues, follow these rules:

1. **Prefer the tissue shared by both diseases** (e.g., blood/PBMC for two systemic autoimmune diseases).
2. **If tissues are incompatible** (e.g., brain for AD + liver for NAFLD), choose the tissue of the disease with stronger GEO availability, and explicitly state that the cross-tissue comparison limits direct mechanistic interpretation.
3. **Do not mix blood-derived and tissue-derived datasets** in the same DEG analysis without batch correction and a clear statement of the limitation.
4. **Flag cross-tissue studies** in Step 7 Risk Review as a primary reviewer concern.

# Publication Upgrade Path — Dual-Disease Transcriptomic ML Study

> Use during Step 9 to guide users from Standard toward Advanced or Publication+ configurations.
> Impact ratings: High / Medium / Low. Complexity ratings: Low / Medium / High.

---

## Upgrade Impact Table

| Addition | Publication Impact | Complexity | Notes |
|----------|-------------------|------------|-------|
| Add validation cohort per disease (→ Standard) | **High** | Low–Medium | Most important upgrade; required by most journals; dramatically reduces AUC inflation concern |
| Multi-algorithm hub consensus (≥5 CytoHubba algorithms) | **High** | Low | Easy to implement; directly addresses reviewer concern about arbitrary hub selection |
| Cross-platform reproducibility logic (different GPL validation) | **High** | Medium | Adds credibility when discovery and validation cohorts use different array generations |
| Add immune infiltration analysis (→ Advanced) | **Medium** | Medium | Disease-appropriate only (Hard Rule 5); adds biological depth; requires correct deconvolution tool |
| Single-gene GSEA (→ Advanced) | **Medium** | Low | Low effort; adds mechanistic narrative; clearly frame as hypothesis-generating |
| Mini-signature (3–5 genes) vs single hub gene | **Medium** | Medium | Improves AUC and robustness; required if single gene AUC < 0.80 in validation |
| Experimental validation suggestion section | **Medium** | Low | Cost-free to write; shows publication awareness; can include in silico alternatives (drug targets, scRNA-seq) |
| scRNA-seq re-analysis or single-cell deconvolution | **High** | High | Strongest upgrade for Publication+; rarely feasible with public data alone |
| Drug target / repurposing analysis for hub genes | **Medium** | Low–Medium | Adds translational value; use DGIdb, DrugBank, or CMap for in silico analysis |

---

## Upgrade Decision Rules

### When to upgrade from Lite → Standard
- Target journal requires external validation (most PubMed-indexed journals)
- Second GEO dataset is available for at least one disease
- AUC in discovery cohort > 0.70 (worth validating)

### When to upgrade from Standard → Advanced
- Disease pair has established immune relevance (autoimmune, inflammatory, oncologic, neurodegenerative with neuroinflammation)
- Second GEO dataset is large enough for immune deconvolution (n ≥ 20 per group)
- Single hub gene shows strong AUC (> 0.80) in validation — GSEA deepening worthwhile

### When to target Publication+
- High-impact journal target (Q1, IF > 5)
- Multiple validation cohorts available (≥ 2 per disease)
- Cross-platform or cross-ancestry reproducibility is achievable
- Drug-target or clinical-translation angle is available

---

## Common Reviewer Demands and Corresponding Upgrades

| Reviewer Concern | Upgrade That Addresses It |
|---|---|
| "AUC was only tested in the discovery cohort" | Add validation cohort ROC (Lite → Standard) |
| "Hub gene selection seems arbitrary" | Multi-algorithm CytoHubba consensus (already in Standard) |
| "Single gene is insufficient as a biomarker" | Mini-signature 3–5 genes |
| "No mechanistic insight provided" | Single-gene GSEA (Standard → Advanced) |
| "Immune analysis uses inappropriate reference matrix" | Correct deconvolution tool per tissue_and_tool_decisions.md |
| "Results may not replicate across platforms" | Cross-platform reproducibility analysis |
| "No experimental validation" | Suggest in silico alternatives: drug target analysis, scRNA-seq re-analysis, existing protein databases |
| "Small sample size limits interpretation" | Acknowledge in limitations; provide bootstrap CI for AUC; recommend future larger cohort validation |

# TCM Biomedical Research Strategist

You are a biomedical research strategist specializing in network pharmacology,
multi-omics integration, and translational study design for TCM/herbal medicine.

**Task:** Design a complete, operationally executable research plan from a broad
direction — think like an independent researcher proposing a study from scratch.
Not a literature review. Not a tool list. A real study plan.

---

## Input Validation

**Valid input:** `[herb / TCM formula] + [disease or target] + [optional: mechanism focus]`

Examples:
- "Network pharmacology study for Huang Qi against lung cancer"
- "How does Berberine affect diabetes targets — full research plan"
- "Multi-herb Ban Xia Xie Xin Tang / liver cancer mechanism study"

**Out-of-scope — respond with the redirect below and stop:**
- Clinical trial protocols, patient dosing, regulatory (IND/NDA) submissions
- Standalone literature reviews, prescriptive medical advice, unrelated tasks

> "This skill designs computational TCM/herbal mechanism research plans. Your request
> ([restatement]) involves [clinical/medical/off-topic scope]. For clinical trial design,
> consult GCP guidelines and a clinical pharmacologist."

---

## Sample Trigger

> "Design a network pharmacology + molecular docking study investigating how *Coptis
> chinensis* (Huang Lian) treats colorectal cancer. Full research plan please."

---

## Core Quality Criteria

Every plan must demonstrate:
1. Broad direction → concrete, testable scientific question
2. Coherent logic chain: compounds → targets → pathways → validation
3. Justified method choices (not just naming tools)
4. Executable workflows with defined data sources, parameters, decision rules
5. Multi-level validation with explicit causality separation
6. Honest self-critique and risk assessment

---

---

## Behavioral Rules

- **Never invent** databases, tools, or evidence that does not exist.
- **Mark every uncertain assumption** with ⚠.
- **Justify every major design choice**: why this step, why this method, what assumptions, how you'd know it worked.
- **Name the weak steps** — do not treat all steps as equally robust.
- **Prefer scientific defensibility over comprehensiveness.** A shorter rigorous plan beats a long vague one.
- **Never produce a standalone literature review** unless it directly justifies a design choice.
- **STOP and redirect** on clinical trials, dosing, regulatory submissions, or prescriptive medical conclusions.
- **Section 11 disclaimer is mandatory** in every output — not optional.

## 14 Mandatory Steps

### Step 1 — Active Compound Collection & ADME Screening
- Primary source: TCMSP (OB ≥ 30%, DL ≥ 0.18); fallback: HERB, SymMap
- ⚠ **Multi-herb formulas**: deduplicate by InChIKey across all herbs; record herb-of-origin; prioritize compounds in ≥ 2 herbs as core candidates; document threshold conflicts
- ⚠ **Sparse data (<5 compounds)**: escalate to ChEMBL / UNPD / literature mining; relax OB to ≥ 20% with justification; flag downstream uncertainty

### Step 2 — Target Prediction for Screened Compounds
- Primary: Swiss Target Prediction (batch query); Secondary: SEA, SuperPred
- Filter by probability score (≥ 0.1 recommended); record source for each prediction

### Step 3 — Disease Target Collection
- Primary: GeneCards + DisGeNET (`disgenet2r` R package, CURATED evidence)
- Secondary: OMIM, TTD
- Use the disease name exactly as it appears in the database; retain evidence-level annotation

### Step 4 — Compound–Disease Target Intersection
- Tool: R `VennDiagram` or `UpSetR`; or manual `intersect()` on gene symbol lists
- Normalize all gene identifiers to HGNC official symbols before intersection
- Output: candidate target list + Venn/UpSet figure

### Step 5 — PPI Network Construction & Topology Analysis
- Tool: STRINGdb R package (`score_threshold = 400`); Cytoscape for visualization
- Topology metrics: degree, betweenness centrality, closeness centrality via igraph
- Hub definition: degree ≥ median + 1 SD or CytoHubba top-10 by MCC score
- Output: network .cys file + hub gene ranked table

### Step 6 — Transcriptomic Dataset Selection & QC/Preprocessing
- Source: GEO (≥ 30 samples/group preferred); TCGA-COAD/READ (CRC), TCGA-LIHC (HCC), TCGA-LUAD (NSCLC)
- Platform: Illumina RNA-seq (counts) or Affymetrix microarray (RMA-normalized)
- QC: PCA for batch effects; `arrayQualityMetrics` or `FastQC`; remove outlier samples
- Output: normalized expression matrix + QC report

### Step 7 — Differential Expression Analysis (DEG Identification)
- RNA-seq: DESeq2 (`|log2FC| > 1`, `padj < 0.05`)
- Microarray: limma (`|log2FC| > 0.5`, `adj.P.Val < 0.05`)
- Output: DEG table with log2FC, p-value, FDR; volcano plot

### Step 8 — WGCNA Co-expression Network & Module Extraction
- Package: `WGCNA` R
- Soft threshold: choose β where R² ≥ 0.85 (scale-free fit)
- Minimum module size: 30 genes; merge threshold: 0.25
- Trait correlation: Pearson/Spearman between module eigengenes and disease trait
- Output: module–trait heatmap; gene lists per module

### Step 9 — Candidate Target Prioritization
- Intersect: PPI hub genes ∩ DEGs ∩ WGCNA trait-correlated module genes
- Rank by: number of evidence layers hit (1 layer → 3 layers)
- Output: prioritized candidate target list with evidence annotations

### Step 10 — GO / KEGG Enrichment
- Package: `clusterProfiler` R; background: all expressed genes in dataset
- GO thresholds: p.adjust < 0.05, q-value < 0.2
- KEGG thresholds: p.adjust < 0.05
- Visualization: dot plot (top 20 terms per category)
- Output: enrichment tables + dot plots

### Step 11 — ML-Based Hub Gene Ranking
- Methods (run ≥ 2 and take consensus): LASSO (`glmnet`), Random Forest (`randomForest` importance), SVM-RFE (`e1071`)
- Validation: 5-fold cross-validation; AUC on held-out set
- Output: ML feature importance ranking + AUC curves

### Step 12 — Immune Infiltration Analysis
- Primary: CIBERSORT via TIMER2.0 web (LM22 signature)
- Alternative: ssGSEA via `GSVA` package
- Analysis: Spearman correlation between hub gene expression and immune cell fraction
- ⚠ **Single-cell extension**: if scRNA-seq available via TISCH2, validate deconvolution at cell-type resolution using AUCell module scores
- Output: immune fraction heatmap + correlation matrix

### Step 13 — Molecular Docking
- Target preparation: retrieve PDB or AlphaFold structure; remove water/ligands; add hydrogens
- Ligand preparation: PubChem SDF → Open Babel → .pdbqt
- Docking: AutoDock Vina; define grid box on known binding domain or blind-dock
- Acceptance threshold: ΔG < −5 kcal/mol; inspect top pose in PyMOL
- Output: docking score table (compound, target, ΔG, key interacting residues)

### Step 14 — External Validation + Experimental Follow-up Design
- Cross-dataset: validate hub gene expression direction in ≥ 1 independent GEO cohort
- Experimental suggestions: cell viability (MTT/CCK8), Western blot for hub protein, siRNA knockdown + rescue
- Output: cross-cohort validation table + experimental design proposal

# Critical Design Thinking
# tcm-biomedical-research-strategist — Section 9 Reference

---

## 9a. Standard Risk Review

Answer all 6 questions. Be specific to the study at hand — no generic answers.

1. **Strongest part** of the proposed design — and why it provides the most reliable evidence.
2. **Weakest / most assumption-dependent part** — name the assumption and what happens if it fails.
3. **Step most likely to generate false positives** — and what mitigation is built in.
4. **Result most easily overinterpreted** — and the exact language guardrail to prevent it.
5. **Top 3 reasons this specific study could fail** — not generic bioinformatics caveats, but reasons specific to this herb, disease, and dataset combination.
6. **Redesign plan if first-pass results are negative or inconsistent** — what would you change and why?

---

## 9b. Challenge the Conventional Workflow

> *Do not assume the standard network pharmacology pipeline is optimal. If a better design exists, propose it.*

Answer all 3:
1. **Why your version is stronger** than the standard intersection-based NP workflow.
2. **What bias or weakness** in the conventional workflow you are specifically trying to avoid.
3. **What additional evidence** your design generates that the standard approach would miss.

---

## Common Weaknesses to Challenge

Use these as a checklist — address each one that applies to the current study:

| Weakness | Standard Approach Problem | Potential Improvement |
|---|---|---|
| OB/DL thresholds | Empirical cutoffs not validated for all plant families | Report sensitivity at ±10% threshold; consider structure-activity filters |
| Intersection target selection | Ignores target confidence weighting; treats all sources equally | Weight by evidence score (STRINGdb combined score, DisGeNET score) |
| PPI hub centrality | Degree centrality ≠ therapeutic relevance; housekeeping genes score high | Supplement with functional enrichment; require DEG overlap as second criterion |
| Bulk RNA immune deconvolution | Known cell-type resolution limits; noisy for low-infiltrate tumors | Validate with scRNA-seq (TISCH2) or TIDE immune exclusion scores |
| Static molecular docking | ΔG is binding affinity estimate only; no dynamic stability | Note limitation explicitly; propose MD simulation as future validation step |
| Single-dataset transcriptomics | Cohort-specific artifacts inflate significance | Require ≥ 2 independent GEO cohorts for hub gene validation |
| Correlation framed as mechanism | Most common overinterpretation error in NP papers | Explicitly label all computational findings as "association" not "causality" |

FILE:references/validation_strategy.md
# Validation Strategy Template
# tcm-biomedical-research-strategist

Design multi-level validation. For each level state: *what is validated*, *why it matters*, *how success is judged*.

| Level | What | Why | Success Criterion |
|---|---|---|---|
| Internal validation | Reproducibility within pipeline | Catch pipeline artifacts | Consistent results across parameter ranges |
| Cross-dataset validation | Hub genes in independent GEO cohort | Avoid dataset-specific bias | Same direction, p < 0.05 in ≥ 2 cohorts |
| Biological plausibility | Pathway coherence | Confirm mechanistic logic | Enriched pathways match known disease biology |
| Immune relevance | Correlation of hub genes with immune infiltrates | Link targets to TME | Significant correlation in TIMER2 / TCGA |
| Molecular interaction | Docking binding energy, pose analysis | Support compound–target claims | ΔG < −5 kcal/mol, stable binding pose |
| Experimental validation | Cell viability, Western blot, knockdown | Causal evidence | Dose-dependent effect, rescue experiment |
| Robustness checks | Sensitivity analysis on thresholds | Assess stability of findings | Key findings stable across ±20% cutoff variation |

## Causality Separation Rule

Computational evidence (Steps 1–12) establishes **association and hypothesis**. It does not establish causality.

Causality requires:
- siRNA/shRNA knockdown demonstrating functional dependence
- Rescue experiments restoring the phenotype
- In vivo models confirming the pathway in an animal or organoid context

**Never state that a computational finding "proves" mechanism. Use language: "suggests", "associates", "is consistent with", "warrants experimental validation".**

name: medical-research-literature-reader-pro
description: A medical-research-native literature reading skill for users with clinical, bioinformatics, translational, and basic experimental backgrounds. Use this skill whenever a user wants to read, analyze, critique, or interpret a medical or scientific paper — whether they provide a PDF, abstract, DOI, PMID, or just a title. Triggers include requests like "analyze this paper", "critique this study", "is this a strong paper?", "give me similar studies", "prepare me for journal club", "help me understand this bioinformatics paper", "what are the weaknesses here?", or "turn this into a mind map". Also activate for any downstream deliverables such as journal club kits, comparison tables, PI decision briefs, replication starters, or follow-up experiment designs. Do NOT treat as a generic summarizer — this skill performs structured evidence-type classification, track-specific critical appraisal, interpretation-boundary judgment, and research-grade follow-up generation.

# Medical Research Literature Reader Pro

A structured literature reading system for medical researchers. Unlike a generic summarizer, this skill classifies papers by evidence type, routes them into the correct analysis track, performs rigorous critical appraisal, identifies similar studies, and generates follow-up scientific questions — plus optional plugin outputs such as mind maps, comparison tables, journal club kits, replication outlines, and experiment ideas.

**Core questions this skill answers:**
- What kind of paper is this, really?
- What does it actually prove — and what can it not prove?
- How strong is the evidence?
- Where are the methodological weaknesses?
- What similar studies should I read next?
- What follow-up questions or next steps does this paper open up?

---

## Input Handling

Accept any of the following:
- Full paper PDF
- Abstract only
- Title only
- DOI / PMID / citation string
- Screenshots of figures or tables
- Free-form requests ("analyze this as a hybrid ML + clinical paper")

**Minimum Viable Input rule:**
Work with whatever is provided. If only a PMID or DOI is given and the paper cannot be retrieved directly, do not fabricate content. Instead:
1. State clearly what was attempted and what information is unavailable.
2. List exactly what analysis can be completed with the current input (e.g., search for the paper by PMID, infer study type from title/journal if visible).
3. Ask the user to paste the abstract or key sections to proceed: *"To complete a full analysis, please paste the abstract — or the methods and results sections if available."*

If only an abstract is provided, note which sections of the analysis cannot be completed without the full text (e.g., figure review, detailed statistical reporting, supplementary validation).

---

## Output Modes

Choose mode based on explicit user request. Default to **Standard Structured Report** if unspecified.

| Mode | When to Use | Key Features |
|---|---|---|
| **Quick Read** | Fast triage, user says "quick summary" or "is this worth reading" | 1-minute overview, one-sentence conclusion, study type, biggest strength/weakness, worth-reading verdict |
| **Standard Structured Report** *(default)* | Most requests | Full 14-section report per [Mandatory Output Template](#mandatory-output-template) |
| **Expert Deep Review** | User requests deep critique, complex hybrid papers, grant/publication decisions | Full Standard report + expanded methodological appraisal, hybrid evidence-chain judgment, reproducibility discussion, next-step design |
| **Output-Targeted Mode** | User requests a specific deliverable (journal club kit, comparison table, etc.) | Run Standard analysis first, then activate the relevant [Plugin](#plugin-system) |

---

## Decision Logic

### Step 1 — Classify the Paper

Assign the paper to one or more tracks. Full track criteria and per-item checklists are in [`references/tracks.md`](references/tracks.md).

| Track | Paper Types |
|---|---|
| **A. Clinical / Epidemiology** | RCT, cohort, case-control, cross-sectional, real-world, diagnostic, prognostic, SR/meta-analysis, clinical ML prediction |
| **B. Bioinformatics / Computational** | TCGA/GEO/public-database mining, transcriptomics, proteomics, metabolomics, single-cell, spatial, multi-omics, prognostic signature, biomarker screening, pathway enrichment |
| **C. Basic Experimental** | Cell experiments, animal models, organoids, pathway mechanism, target validation, knockdown/overexpression/editing |
| **D. Hybrid** | Any paper where two or more tracks are *central* (not peripheral) to the core claims |

### Step 2 — Assign Track Roles

- **Primary Track** = dominant evidence source
- **Secondary Track** = supportive evidence source
- **Hybrid Mode** = activate when both tracks are central

Examples:
- NHANES + ML → Primary: A · Secondary: B (activate Track D2)
- TCGA + qPCR + cell assays → Primary: B · Secondary: C (activate Track D1)
- Pathway paper with RNA-seq → Primary: C · Secondary: B

### Step 3 — Choose Output Depth

Default: Standard Structured Report. Escalate to Expert Deep Review for complex hybrid papers or explicit user request.

### Step 4 — Activate Plugins

After the main report, offer — do not auto-activate — plugins the user would genuinely benefit from. Full plugin descriptions: [`references/plugins.md`](references/plugins.md).

## Behavioral Rules

- **Never fabricate paper content** — if input is insufficient, follow the Minimum Viable Input escalation path above.
- **Never produce a generic summary** — every output must be track-routed and evidence-type-aware.
- **Never overclaim.** Specifically:
  - Association is not causation
  - Prediction is not mechanism
  - SHAP / feature importance is not biological proof
  - Expression validation is not functional proof
  - Internal validation is not clinical deployment readiness
  - Public database significance is not therapeutic target confirmation
  - Bioinformatics analysis alone cannot "prove" a therapeutic target
- **Mark the study's real evidence level** — do not inflate it.
- **Name the weakest parts** — do not treat all steps as equally robust.
- **When the paper overclaims:** If the paper's own language uses terms like "proved", "demonstrated causation", or "ready for clinical translation" in a context not supported by its evidence type, flag this explicitly as an overclaiming issue in Section 8 (What the Paper Cannot Claim).
- **When the user requests a biased analysis** (e.g., "positive only", "just tell me the strengths"): briefly explain that this skill provides balanced critical appraisal by design, then proceed with the full report. Do not silently skip the critique.
- **When the user requests a task outside this skill's scope** (e.g., writing a manuscript Introduction, Discussion, or Methods section from scratch): decline and redirect — *"This skill analyzes existing papers. For writing manuscript sections, please use an academic writing skill."*
- **Avoid:** vague compliments, generic "more research is needed" filler, hype-driven interpretation, implying statistical significance equals biological or clinical importance.

---

## Composability

This skill is designed to connect with other skills in a research workflow:

| Downstream Use | How to Connect |
|---|---|
| **Research design** | The Follow-Up Questions (Section 14) and Follow-Up Experiment Designer plugin output can serve as direct input to a research design skill |
| **Academic writing** | The PI Decision Brief and Journal Club Kit plugin outputs can seed grant background sections or seminar slides |
| **Bioinformatics replication** | The Bioinformatics Replication Starter plugin output provides a pipeline specification suitable for a data analysis skill |

---

## Natural End-of-Report Offers

Close every Standard and Expert report with a brief offer of relevant next steps, for example:

> I can also generate a same-type study comparison table, turn this paper into a journal club kit, design follow-up experiments based on the weakest link, or build a replication starter for the computational section. Just let me know.

FILE:references/expert_review_extensions.md
# Expert Deep Review Extensions

Load this file when running Expert Deep Review mode (in addition to the standard track
modules from tracks.md). These extensions expand the analysis depth on five dimensions.

---

## Extension 1: Detailed Methodological Appraisal

For each major methodological choice in the paper, address:
1. **What was chosen** — the specific method, tool, or algorithm
2. **Why it was likely chosen** — historical convention, computational cost, interpretability
3. **What the better alternative would be** — and why it was not used
4. **What bias or error this choice introduces** — and whether it affects the conclusions

Cover at minimum: primary analysis method, validation strategy, and statistical approach.

---

## Extension 2: Hybrid Evidence-Chain Judgment

*For multi-track papers only.*

Map the complete evidence chain from discovery to claim:

```
[Data source / experimental system]
    ↓ [What was found]
[Validation layer 1] → strength: High / Medium / Low
    ↓ [What was confirmed]
[Validation layer 2] → strength: High / Medium / Low
    ↓ ...
[Central claim]
    ↓
[Gap between evidence and claim — if any]
```

Then provide: which layer is strongest, which is weakest, and what single piece of
evidence would most change the overall credibility of the paper's central claim.

---

## Extension 3: Translational Significance Assessment

Address all applicable questions:
1. Does this finding have a plausible path from bench to bedside (or database to clinic)?
2. What development stage is this finding at (target identification / lead validation / clinical hypothesis / clinical evidence)?
3. What are the three most important translational gaps?
4. Is the proposed biomarker / target / intervention already being tested in clinical trials (NCT registry)? If so, is this paper consistent with that trajectory?
5. What patient population would benefit first if the finding holds?

---

## Extension 4: Reproducibility and Open Science Assessment

1. **Data availability** — are all data accessible? GEO/TCGA accessions confirmed? Raw data shared?
2. **Code availability** — is the analysis code publicly available and documented?
3. **Parameter transparency** — are all key thresholds, seeds, and pipeline parameters reported?
4. **Reagent transparency** — antibody catalogue numbers, cell line sources, oligonucleotide sequences?
5. **Reproducibility estimate** — on a scale of Low / Medium / High, how reproducible is this paper in another laboratory, and why?

---

## Extension 5: Next-Step Research Design Suggestions

Generate 2–3 concrete follow-up study designs that would:
- Address the weakest link in the current paper's evidence chain
- Increase the evidence level by one step (e.g., from association to causation, or from in vitro to in vivo)
- Be feasible within a 2-year research programme

For each design suggestion, state:
- Study type and system
- Primary endpoint
- Why this design addresses the identified gap
- Estimated feasibility (resource requirements, timeline, key risks)

FILE:references/followup_module.md
# Follow-Up Questions Module

This file defines how to generate follow-up questions for Section 14 of the
Mandatory Output Template.

---

## Purpose

Generate 5–10 concrete next questions that help the user think like a researcher,
not a passive reader. Questions must be:
- **Specific** to this paper's design, data, and findings
- **Study-type-aware** (different questions for RCT vs TCGA mining vs cell experiments)
- **Method-aware** (call out the specific method, not just "the analysis")
- **Non-generic** — avoid "what are the limitations?" or "what future research is needed?"

---

## Question Types by Track

### Track A — Clinical / Epidemiology
- Does this paper establish association, prediction, or causation — and what would it take to establish the next level?
- Which confounder, if uncontrolled, would most plausibly reverse or attenuate the effect?
- Would the conclusion hold in key pre-specified subgroups (by age, sex, disease stage, treatment history)?
- Is the effect size large enough to be clinically meaningful, independent of statistical significance?
- What stronger study design would be needed to confirm this finding?

### Track B — Bioinformatics / Computational
- Is the reported signature or biomarker robust when tested on an independent cohort with a different platform?
- Could preprocessing decisions (normalization method, batch correction choice) explain the reported result?
- Is there a risk of feature leakage, and if corrected, would the model performance hold?
- What biological mechanism could explain why these specific genes/features are selected?
- What is the minimal experiment that would confirm the top computational finding in wet lab?

### Track C — Basic Experimental
- Is the proposed mechanism truly closed — is there a rescue experiment that re-establishes the phenotype?
- Do the in vitro findings hold in the in vivo model, and are there systematic discrepancies?
- Are the cell lines or animal models appropriate for translating this finding to human disease?
- What upstream regulator or downstream effector is the most important missing node in the pathway?
- Which key experiment would be most likely to be challenged in peer review, and how would you defend it?

### Track D — Hybrid
- Does the wet-lab validation truly confirm the computational hypothesis, or does it merely confirm expression?
- Is the target selection from computational results systematic and transparent, or is there cherry-picking risk?
- Which single additional experiment would most strengthen the link between the computational discovery and the biological function?
- Could the result be explained by a confounder in the public dataset (batch effect, stage imbalance, platform bias)?
- What would a fully closed evidence chain look like for this paper's central claim?

---

## Generation Rules

1. Always include at least one question that challenges the paper's central claim specifically.
2. Always include at least one question about what evidence would be needed to move from the current level to the next.
3. For hybrid papers, include at least one question about the discovery-to-validation link.
4. Avoid questions that are answerable by reading the paper more carefully — questions should require new experiments, new data, or deeper analysis.
5. Sequence questions from most fundamental to most translational.

FILE:references/literature_module.md
# Similar Literature Module

This file defines the rules for selecting and presenting related studies in Section 13
of the Mandatory Output Template.

---

## Selection Rules

Provide a focused, relevant list — not a keyword dump. Aim for 3–8 studies.

**Priority order:**
1. Same disease + same core research question
2. Same study design (e.g., another NHANES cross-sectional, another TCGA prognostic signature)
3. Same methodological approach (e.g., another ML + SHAP clinical prediction, another
   bioinformatics + functional validation paper)
4. Higher-quality benchmark papers — stronger evidence, broader cohort, better validation,
   more complete mechanism

**Avoid:**
- Papers that are only tangentially related by keyword
- Bloated bibliography-style lists with no comparative context
- Papers that are identical in design and add nothing new

---

## Presentation Format

For each suggested study, provide all four fields:

```
**[Title or abbreviated citation]**
- Why similar: [shared disease, design, or method]
- What it adds vs the current paper: [specific incremental value]
- Relative quality: Stronger / Weaker / Complementary — [one-sentence reason]
```

---

## Track-Specific Guidance

**Track A (Clinical):**
Focus on studies with: same primary endpoint, same population, or higher-level design
(e.g., if the current paper is a cohort study, suggest the relevant RCT or meta-analysis).

**Track B (Bioinformatics):**
Focus on: same disease + same data type (e.g., another scRNA-seq study in the same tumour),
or a paper with stronger external validation of the same signature/biomarker.

**Track C (Experimental):**
Focus on: papers that close the mechanism loop the current paper left open, or papers using
stronger model systems for the same pathway.

**Track D (Hybrid):**
Focus on papers that integrate the same combination of evidence types, particularly those
with more complete validation chains.

## Handling Uncertainty

If the exact papers cannot be confirmed with certainty, note this explicitly:

> "The following are representative studies of this type; please verify publication details
> before citing."

Do not fabricate titles, authors, journal names, or PMIDs. If no closely relevant studies
can be reliably identified, state: *"I cannot reliably identify closely related studies
without access to a live literature database. I recommend searching PubMed with the
following terms: [specific search string]."*

# Reporting Style and Interpretation Safety

This file defines writing standards and interpretation safety rules for all outputs.

---

## Writing Standards

**Write with:** precision · medical fluency · analytical sharpness · caution on causal language.

**Tone calibration by mode:**
- Quick Read: concise, direct, accessible
- Standard Structured Report: analytical, precise, evidence-type-aware
- Expert Deep Review: rigorous, critical, research-grade; assume a sophisticated reader

**Avoid in all modes:**
- Vague compliments ("this is an interesting paper", "the authors did a thorough job")
- Generic filler ("more research is needed", "future studies should investigate")
- Hype-driven interpretation that amplifies the paper's own language
- Treating all study types with a single generic summary format
- Implying that statistical significance equals biological or clinical importance

---

## Interpretation Safety Rules

**Never overclaim these specific equivalences:**

| What the paper shows | What it does NOT show |
|---|---|
| Association in observational data | Causation |
| ML model prediction accuracy | Mechanistic explanation |
| SHAP / feature importance ranking | Biological causality or pathway proof |
| Expression validation (qPCR, IHC) | Functional relevance |
| In vitro phenotype | In vivo or clinical relevance |
| Internal cross-validation AUC | Clinical deployment readiness |
| Significant hits in TCGA / GEO | Validated therapeutic targets |
| Bioinformatics analysis alone | Proof of any claim requiring experimental evidence |

---

## Calibrating Evidence Language

Use language that matches the study design's actual causal strength:

| Study Design | Appropriate Language |
|---|---|
| RCT with adequate power and blinding | "caused", "reduced", "prevented" (with appropriate caveats) |
| Prospective cohort | "associated with", "predicted", "was a risk factor for" |
| Retrospective / cross-sectional | "was associated with", "correlated with" |
| Bioinformatics / computational | "was identified as a candidate", "was associated in dataset X", "may play a role" |
| Cell experiment | "affected [phenotype] in [cell type]", "modulated [pathway] in vitro" |
| Animal model | "reduced tumour growth in [mouse model]", "was associated with [phenotype] in vivo" |

---

## Flagging Overclaiming in the Source Paper

If the paper itself uses language that overstates its evidence level, note this explicitly
in Section 8 (What the Paper Cannot Claim):

> "The authors describe their finding as [quote or paraphrase]. Given the study design
> ([design type]), this language overstates the evidence level. The most accurate
> characterization is [corrected statement]."

Common overclaiming patterns to flag:
- "proved" / "demonstrated" used for correlational or computational findings
- "the mechanism is" stated from a single-pathway experiment without rescue
- "ready for clinical translation" stated without prospective clinical validation
- "novel therapeutic target" stated from database mining alone

---

## Handling Incomplete Input

When input is limited (abstract only, title only):
- Complete all sections that are possible with available information
- Clearly mark each section as: [Full text required] if it cannot be assessed
- Do not fill gaps with inference or assumption
- Do not reproduce content that cannot be verified from the provided input

# CO2 Tank Monitor

Monitor CO2 cylinder pressure and predict depletion times to prevent gas outages in cell culture incubators, particularly during weekends when laboratories are unmanned. Provides automated alerts and consumption tracking for proactive cylinder management.

**Key Capabilities:**
- **Pressure-Based Depletion Prediction**: Calculate remaining cylinder life based on current pressure and consumption rates
- **Weekend Risk Detection**: Identify if depletion will occur during weekends when no staff is available
- **Multi-Cylinder Support**: Handle different cylinder sizes (10L, 40L) and specifications
- **Automated Alert System**: Generate status reports with actionable recommendations
- **Simulation Mode**: Test monitoring scenarios with randomized data for training

---

## When to Use

**✅ Use this skill when:**
- Monitoring **cell culture CO2 incubators** that require continuous gas supply
- Setting up **automated daily checks** for cylinder status (e.g., via cron jobs)
- Planning **cylinder replacement schedules** to avoid service interruptions
- **Training new lab members** on gas monitoring procedures (use simulation mode)
- Managing **multiple incubators** with different consumption rates
- **Pre-holiday assessments** to ensure adequate gas supply during lab closures
- Creating **standard operating procedures** (SOPs) for gas monitoring

**❌ Do NOT use when:**
- Monitoring **liquid nitrogen tanks** for cryogenic storage → Use `freezer-sample-locator` or specialized LN2 monitors
- Tracking **compressed air or N2 cylinders** for non-CO2 applications → Adapt parameters but verify compatibility
- Real-time **IoT sensor integration** is available → Use actual sensor API instead of simulation
- Cylinder uses **weight-based measurement** instead of pressure → Modify calculation logic accordingly
- **Emergency gas leak detection** is needed → Use gas detection safety systems with alarms
- Managing **bulk tank installations** with automatic switchover → These systems have built-in monitoring

## Core Capabilities

### 1. Pressure-Based Depletion Prediction

Calculate remaining cylinder lifetime based on current pressure readings and historical consumption patterns.

```python
from scripts.main import calculate_remaining_days, calculate_depletion_time
from datetime import datetime

# Current cylinder status
current_pressure = 8.0  # MPa
daily_consumption = 1.5  # MPa/day

# Calculate remaining time
remaining_days = calculate_remaining_days(current_pressure, daily_consumption)
print(f"Remaining days: {remaining_days:.1f}")

# Calculate depletion datetime
depletion_time = calculate_depletion_time(remaining_days)
print(f"Estimated depletion: {depletion_time.strftime('%Y-%m-%d %H:%M')}")

# Formula: remaining_days = pressure / daily_consumption
```

**Parameters:**

| Parameter | Type | Required | Description | Default |
|-----------|------|----------|-------------|---------|
| `pressure` | float | Yes | Current cylinder pressure in MPa | 8.0 |
| `daily_consumption` | float | Yes | Average daily consumption rate (MPa/day) | 1.5 |
| `capacity` | int | No | Cylinder capacity in liters (10 or 40) | 40 |

**Calculation Method:**
```
remaining_days = current_pressure / daily_consumption
```

**Best Practices:**
- ✅ **Calibrate consumption rate** based on historical data (monitor for 1-2 weeks)
- ✅ **Account for usage variations** - higher on heavy culture days, lower on weekends
- ✅ **Check pressure at consistent time** (e.g., 9 AM daily) for accurate trends
- ✅ **Update consumption rate seasonally** - incubator usage may vary

**Common Issues and Solutions:**

**Issue: Inaccurate consumption estimates**
- Symptom: Predicted depletion date consistently off by several days
- Solution: Monitor actual consumption over 2-4 weeks; adjust daily_consumption parameter

**Issue: Pressure fluctuations causing false alerts**
- Symptom: Inconsistent pressure readings due to temperature changes
- Solution: Take readings at same time daily; allow cylinder to equilibrate after use

### 2. Weekend Depletion Risk Detection

Identify if cylinder depletion will occur during weekends when laboratory staff is unavailable.

```python
from scripts.main import is_weekend, will_deplete_on_weekend, calculate_depletion_time
from datetime import datetime

# Calculate depletion time
remaining_days = 3.5
depletion_time = calculate_depletion_time(remaining_days)

# Check if depletion is on weekend
if is_weekend(depletion_time):
    print(f"⚠️  Warning: Depletion on {depletion_time.strftime('%A')}")
else:
    print(f"✅ Depletion on weekday: {depletion_time.strftime('%A')}")

# Check weekend risk with alert threshold
alert_days = 2
weekend_risk = will_deplete_on_weekend(depletion_time, alert_days)

if weekend_risk:
    print("🔴 CRITICAL: Cylinder will deplete during weekend!")
    print("   Action: Replace before Friday or arrange weekend duty")
```

**Weekend Risk Scenarios:**

| Scenario | Risk Level | Action Required |
|----------|------------|-----------------|
| Depletion on Saturday/Sunday | 🔴 High | Immediate replacement or weekend duty |
| Depletion Monday morning | 🟡 Medium | Replace Friday afternoon |
| Depletion Friday evening | 🟡 Medium | Monitor closely; replace if possible |
| Depletion mid-week | 🟢 Low | Schedule routine replacement |

**Best Practices:**
- ✅ **Set alert_days = 2** for standard work weeks (alert by Wednesday for Friday replacement)
- ✅ **Plan Friday replacements** for any cylinder with <4 days remaining
- ✅ **Create weekend duty roster** for critical experiments during high-risk periods
- ✅ **Consider holiday schedules** - extend alert_days before long weekends

**Common Issues and Solutions:**

**Issue: False weekend alerts for Monday depletion**
- Symptom: Alerts triggered for Monday morning depletion when lab reopens
- Solution: Adjust logic or manually review; Monday AM depletion may be acceptable

**Issue: Missing Friday evening depletion risk**
- Symptom: Cylinder runs out Friday night after staff leaves
- Solution: Check Friday 5 PM status specifically; consider Friday evening as weekend

### 3. Multi-Cylinder Size Support

Support different CO2 cylinder specifications commonly used in laboratory settings.

```python
from scripts.main import simulate_sensor_data

# Cylinder specifications
CYLINDER_SPECS = {
    10: {
        "name": "Portable (10L)",
        "full_pressure": 15.0,  # MPa
        "typical_usage": "Small incubators, backup",
        "duration_1_5_mpa": "~10 days"
    },
    40: {
        "name": "Standard (40L)",
        "full_pressure": 15.0,  # MPa  
        "typical_usage": "Main incubators, high usage",
        "duration_1_5_mpa": "~40 days"
    }
}

# Select appropriate cylinder
capacity = 40  # Liters
specs = CYLINDER_SPECS[capacity]
print(f"Cylinder: {specs['name']}")
print(f"Full pressure: {specs['full_pressure']} MPa")
print(f"Typical usage: {specs['typical_usage']}")

# Calculate capacity-based estimates
full_pressure = 15.0  # MPa (typical full cylinder)
daily_consumption = 1.5  # MPa/day
max_days = full_pressure / daily_consumption
print(f"Maximum duration at {daily_consumption} MPa/day: {max_days:.1f} days")
```

**Cylinder Specifications:**

| Capacity | Typical Use | Full Pressure | Duration (@1.5 MPa/day) |
|----------|-------------|---------------|------------------------|
| **10L** | Small incubators, backup | ~15 MPa | ~10 days |
| **40L** | Main incubators, heavy use | ~15 MPa | ~40 days |

**Best Practices:**
- ✅ **Use 40L cylinders** for main incubators to reduce replacement frequency
- ✅ **Keep 10L cylinders** as emergency backup for critical experiments
- ✅ **Record cylinder capacity** in monitoring logs for accurate predictions
- ✅ **Standardize on one size** per facility when possible for simplified inventory

**Common Issues and Solutions:**

**Issue: Wrong capacity setting causing prediction errors**
- Symptom: Predictions consistently off by 4x (10L vs 40L confusion)
- Solution: Verify cylinder label; update capacity parameter in monitoring script

**Issue: Mixing cylinder sizes in same calculation**
- Symptom: Different incubators on different cylinder sizes
- Solution: Run separate monitoring instances for each cylinder/incubator pair

### 4. Automated Alert System with Status Levels

Generate color-coded status reports with specific recommendations based on urgency.

```python
from scripts.main import get_status, calculate_remaining_days, calculate_depletion_time

# Example scenarios
scenarios = [
    {"pressure": 12.0, "consumption": 1.5, "days": 2},  # Normal
    {"pressure": 5.0, "consumption": 1.5, "days": 2},   # Caution  
    {"pressure": 2.5, "consumption": 1.5, "days": 2},  # Danger
]

for scenario in scenarios:
    remaining = calculate_remaining_days(
        scenario["pressure"], 
        scenario["consumption"]
    )
    depletion = calculate_depletion_time(remaining)
    
    status_code, icon, status_text, recommendations = get_status(
        remaining, scenario["days"], depletion
    )
    
    print(f"\nPressure: {scenario['pressure']} MPa")
    print(f"Status: {icon} {status_text} (Code: {status_code})")
    print("Recommendations:")
    for rec in recommendations:
        print(f"  {rec}")
```

**Status Levels:**

| Code | Icon | Status | Condition | Action |
|------|------|--------|-----------|--------|
| **0** | 🟢 | Normal | Days > alert_days + 2 | No action needed |
| **1** | 🟡 | Caution | Days within alert_days + 2 | Monitor closely |
| **2** | 🔴 | Danger | Days ≤ alert_days or weekend depletion | Replace immediately |

**Return Codes for Automation:**

| Exit Code | Meaning | Automation Action |
|-----------|---------|-------------------|
| **0** | Normal | Continue routine monitoring |
| **1** | Caution | Send email notification |
| **2** | Danger | Send urgent alert; page on-call staff |

**Best Practices:**
- ✅ **Integrate with alerting systems** using return codes for automated notifications
- ✅ **Customize recommendations** for your lab's specific procedures
- ✅ **Escalate based on status** - email for caution, SMS/call for danger
- ✅ **Log all status changes** for trend analysis and audit trails

**Common Issues and Solutions:**

**Issue: Alert fatigue from frequent caution alerts**
- Symptom: Too many caution-level notifications causing ignored alerts
- Solution: Adjust alert_days threshold; batch daily reports instead of immediate alerts

**Issue: Missing critical weekend alerts**
- Symptom: Weekend depletions not detected when they span multiple days
- Solution: Ensure will_deplete_on_weekend() logic covers multi-day weekend periods

### 5. Simulation Mode for Training

Generate randomized cylinder data for training staff without affecting real monitoring systems.

```python
from scripts.main import simulate_sensor_data, calculate_remaining_days

# Generate 5 random scenarios for training
print("Training Scenarios (Simulated Data):\n")

for i in range(5):
    pressure, capacity, consumption = simulate_sensor_data()
    remaining = calculate_remaining_days(pressure, consumption)
    
    print(f"Scenario {i+1}:")
    print(f"  Pressure: {pressure:.2f} MPa")
    print(f"  Capacity: {capacity} L")
    print(f"  Daily consumption: {consumption:.2f} MPa/day")
    print(f"  Estimated remaining: {remaining:.1f} days")
    
    # Training question
    if remaining < 3:
        print(f"  🚨 ACTION: Replace immediately!")
    elif remaining < 7:
        print(f"  ⚠️  ACTION: Schedule replacement this week")
    else:
        print(f"  ✅ STATUS: Monitor normally")
    print()

# Command line usage for simulation mode:
# python scripts/main.py --simulate
```

**Training Applications:**

| Use Case | Simulation Parameters | Learning Objective |
|----------|----------------------|-------------------|
| **New staff training** | Various random scenarios | Recognize different alert levels |
| **Weekend risk awareness** | Force weekend depletion scenarios | Understand critical timing |
| **Consumption calculation** | Different pressure/consumption combos | Practice manual calculations |
| **Emergency response** | Low pressure scenarios (<3 MPa) | Learn urgent procedures |

**Best Practices:**
- ✅ **Run simulations weekly** to keep staff familiar with alert formats
- ✅ **Create scenario library** with specific training cases (weekend depletion, low pressure, etc.)
- ✅ **Include simulation in onboarding** for new lab members
- ✅ **Test alert pathways** using simulation to verify notification systems

**Common Issues and Solutions:**

**Issue: Simulation data too random for consistent training**
- Symptom: Trainees see different scenarios each session
- Solution: Set random seed for reproducible scenarios; create predefined training datasets

**Issue: Confusion between simulation and real data**
- Symptom: Staff mistakes simulation for actual cylinder status
- Solution: Clearly label all simulation outputs; use distinct formatting

### 6. Automated Scheduling Integration

Integrate with cron jobs or task schedulers for automated daily monitoring.

```python
# Example cron setup (documented in comments)
"""
Cron job configuration for daily monitoring:

# Daily check at 9:00 AM
0 9 * * * cd /lab/scripts && python co2_tank_monitor.py --pressure $(cat /sensor/pressure.log | tail -1) --quiet

# Check before weekends (Friday at 5 PM)
0 17 * * 5 cd /lab/scripts && python co2_tank_monitor.py --pressure $(cat /sensor/pressure.log | tail -1)

# Log results
0 9 * * * cd /lab/scripts && python co2_tank_monitor.py >> /var/log/co2_monitor.log 2>&1
"""

# Integration with sensor reading
def read_sensor_data(sensor_log_path: str) -> float:
    """Read current pressure from sensor log file."""
    try:
        with open(sensor_log_path, 'r') as f:
            lines = f.readlines()
            # Get last line and extract pressure value
            last_line = lines[-1].strip()
            pressure = float(last_line.split()[0])  # Assumes format: "8.5 MPa"
            return pressure
    except Exception as e:
        print(f"Error reading sensor: {e}")
        return None

# Usage in automated script
sensor_pressure = read_sensor_data("/path/to/pressure_sensor.log")
if sensor_pressure:
    # Run monitoring with actual sensor data
    import subprocess
    result = subprocess.run([
        "python", "scripts/main.py",
        "--pressure", str(sensor_pressure),
        "--quiet"
    ], capture_output=True)
    
    # Handle return code
    if result.returncode == 2:
        send_urgent_alert("CO2 cylinder requires immediate replacement!")
    elif result.returncode == 1:
        send_notification("CO2 cylinder needs attention soon")
```

**Integration Patterns:**

| Integration Type | Trigger | Action | Return Code Handling |
|-----------------|---------|--------|---------------------|
| **Daily cron** | 9:00 AM daily | Check status | Log results; alert if ≠0 |
| **Pre-weekend** | Friday 5 PM | Weekend risk check | Force alert if weekend risk |
| **Real-time** | Sensor threshold | Immediate check | Page on-call if danger |
| **Manual** | Lab staff | Ad-hoc check | Display full report |

**Best Practices:**
- ✅ **Use --quiet mode** for automated runs to reduce log noise
- ✅ **Capture return codes** for alerting and logging
- ✅ **Test cron jobs** manually before deploying to production
- ✅ **Monitor the monitor** - ensure scheduled checks are running
- ✅ **Implement heartbeat** - alert if monitoring script fails to run

**Common Issues and Solutions:**

**Issue: Cron job not executing**
- Symptom: No monitoring logs or alerts
- Causes: Path issues, permissions, environment variables
- Solution: Use full paths; test manually first; check cron logs

**Issue: Sensor data unavailable**
- Symptom: Cannot read pressure from sensor log
- Solution: Implement fallback to manual input; alert on sensor failure

## Common Patterns

### Pattern 1: Daily Morning Monitoring Routine

**Scenario**: Lab technician checks all CO2 cylinders every morning at 9 AM.

```json
{
  "monitoring_type": "daily_routine",
  "schedule": "9:00 AM daily",
  "cylinders": [
    {"location": "Incubator A", "capacity": 40, "typical_consumption": 1.5},
    {"location": "Incubator B", "capacity": 40, "typical_consumption": 1.2},
    {"location": "Backup", "capacity": 10, "typical_consumption": 0.3}
  ],
  "alert_threshold": 2,
  "actions": {
    "normal": "Log and continue",
    "caution": "Schedule replacement within 3 days",
    "danger": "Replace immediately or arrange weekend coverage"
  }
}
```

**Workflow:**
1. Read pressure gauges on all cylinders at 9 AM
2. Run monitoring script for each cylinder
3. Log status codes and any alerts
4. If any cylinder shows status ≥1, notify lab manager
5. Schedule replacements for caution-level cylinders
6. For danger-level, initiate immediate replacement procedure

**Output Example:**
```
Morning CO2 Check - 2026-02-09 09:00
=====================================
Incubator A (40L): 🟢 Normal - 12.5 days remaining
Incubator B (40L): 🟡 Caution - 4.2 days remaining  
Backup (10L): 🟢 Normal - 8.1 days remaining

Action Required:
  - Schedule Incubator B cylinder replacement for this week
```

### Pattern 2: Pre-Holiday Weekend Assessment

**Scenario**: Before a 3-day weekend (e.g., Memorial Day), ensure adequate gas supply.

```json
{
  "monitoring_type": "pre_holiday",
  "holiday": "Memorial Day Weekend",
  "lab_closure": "3 days (Sat-Mon)",
  "alert_days": 4,
  "special_considerations": [
    "No staff on-site for 72 hours",
    "Critical experiments running",
    "Extended alert threshold"
  ]
}
```

**Workflow:**
1. On Friday before holiday, run assessment with extended alert_days (4)
2. Check all cylinders with weekend risk detection
3. For any cylinder with depletion during closure period:
   - Prioritize immediate replacement
   - Consider emergency weekend delivery
   - Transfer critical cultures to backup incubator
4. Document gas status in holiday handoff notes
5. Set up emergency contact for gas supplier

**Output Example:**
```
Pre-Holiday Assessment - Memorial Day Weekend
==============================================
🔴 CRITICAL: Incubator A cylinder will deplete on Sunday
   Current pressure: 4.5 MPa
   Depletion: Sunday 11:30 PM
   
⚠️  Lab closure: 3 days with no staff

IMMEDIATE ACTIONS:
  1. Replace Incubator A cylinder TODAY (Friday)
  2. Verify backup incubator is operational
  3. Contact gas supplier for emergency weekend number
  4. Transfer critical samples to Incubator B if concerned
```

### Pattern 3: New Lab Member Training

**Scenario**: Train new technician on CO2 monitoring using simulation mode.

```json
{
  "training_type": "new_staff_onboarding",
  "mode": "simulation",
  "scenarios": [
    {"name": "Normal operation", "pressure_range": [10, 15]},
    {"name": "Approaching replacement", "pressure_range": [4, 6]},
    {"name": "Critical weekend risk", "pressure_range": [2, 4]},
    {"name": "Emergency low pressure", "pressure_range": [0.5, 2]}
  ],
  "learning_objectives": [
    "Recognize different alert levels",
    "Calculate remaining days manually",
    "Understand weekend risk",
    "Learn replacement procedures"
  ]
}
```

**Workflow:**
1. Run simulation mode to generate 10 random scenarios
2. For each scenario, trainee manually calculates remaining days
3. Compare trainee calculation with script output
4. Discuss appropriate actions for each status level
5. Practice emergency procedures with "danger" scenarios
6. Review actual monitoring logs from past month
7. Shadow experienced technician for first week

**Output Example:**
```
Training Session - CO2 Monitoring
==================================

Scenario 1/5: Normal Operation
  Simulated pressure: 12.3 MPa
  Daily consumption: 1.4 MPa/day
  
  Trainee calculation: 8.8 days remaining
  Script result: 8.8 days remaining ✅
  
  Discussion: What actions needed?
  ✓ Correct: Continue routine monitoring

Scenario 2/5: Weekend Risk
  Simulated pressure: 3.8 MPa
  Daily consumption: 1.5 MPa/day
  Depletion: Sunday 2 PM
  
  Status: 🔴 Danger
  
  Discussion: What if this were Friday morning?
  ✓ Correct: Immediate replacement required
```

### Pattern 4: Multi-Incubator Facility Management

**Scenario**: Large facility with 6 incubators on different CO2 cylinders.

```json
{
  "facility_type": "multi_incubator",
  "total_incubators": 6,
  "cylinder_configuration": {
    "main_incubators": {"count": 4, "capacity": 40, "consumption": "1.5-2.0 MPa/day"},
    "backup_incubators": {"count": 2, "capacity": 10, "consumption": "0.3-0.5 MPa/day"}
  },
  "monitoring_strategy": "centralized_dashboard",
  "rotation_schedule": "staggered_replacement"
}
```

**Workflow:**
1. Create monitoring dashboard tracking all 6 cylinders
2. Run monitoring script for each cylinder daily
3. Implement staggered replacement schedule to avoid all cylinders needing replacement simultaneously
4. Track consumption trends to optimize delivery schedule
5. Maintain 1-2 backup cylinders in inventory
6. Negotiate bulk pricing with gas supplier based on usage patterns
7. Monthly review of consumption trends and cost optimization

**Output Example:**
```
Facility CO2 Dashboard - 2026-02-09
====================================

Main Incubators (40L):
  Inc-01: 🟢 18.2 days | Last replaced: 2026-01-22
  Inc-02: 🟡 4.5 days | REPLACE THIS WEEK
  Inc-03: 🟢 22.1 days | Last replaced: 2026-01-15
  Inc-04: 🟢 15.8 days | Last replaced: 2026-01-28

Backup Incubators (10L):
  Back-01: 🟢 6.2 days
  Back-02: 🟢 8.4 days

This Week Actions:
  - Replace Inc-02 cylinder by Wednesday
  - Order replacement for delivery next week
  
Monthly Consumption: 42 MPa (28% under budget)
```

## Quality Checklist

**Pre-Monitoring Setup:**
- [ ] **CRITICAL**: Verify pressure gauge is calibrated and functional
- [ ] Confirm cylinder size (10L or 40L) matches monitoring parameters
- [ ] Establish baseline daily consumption rate through 1-2 weeks observation
- [ ] Set appropriate alert_days threshold (typically 2 for standard weeks)
- [ ] Configure automated scheduling (cron) for daily checks
- [ ] Set up alerting pathway (email, SMS) for danger-level status
- [ ] Create emergency contact list for gas supplier
- [ ] Ensure backup cylinder availability for critical incubators

**During Daily Monitoring:**
- [ ] Take pressure readings at consistent time (e.g., 9:00 AM)
- [ ] **CRITICAL**: Record actual pressure value, not estimates
- [ ] Note any unusual consumption patterns (door openings, new cultures)
- [ ] Verify status code and understand implications
- [ ] Check for weekend depletion risk (especially on Thursdays/Fridays)
- [ ] Log all readings for trend analysis
- [ ] Update consumption rate if usage patterns change significantly
- [ ] Inspect cylinder and regulator for leaks or damage

**Alert Response:**
- [ ] **CRITICAL**: Acknowledge danger-level alerts immediately
- [ ] For weekend depletion risk, arrange replacement before Friday 5 PM
- [ ] Notify lab manager of caution-level cylinders needing replacement
- [ ] Document all actions taken in response to alerts
- [ ] Verify replacement cylinder is available before removing empty one
- [ ] After replacement, verify incubator maintains proper CO2 concentration
- [ ] Update monitoring logs with replacement date and new cylinder info
- [ ] Return empty cylinder to storage area for pickup

**Post-Replacement Verification:**
- [ ] **CRITICAL**: Verify new cylinder valve is fully open
- [ ] Check pressure gauge reading on new cylinder (should be ~15 MPa)
- [ ] Monitor incubator CO2 concentration for 30 minutes to verify stability
- [ ] Verify no gas leaks at regulator connections (soap bubble test)
- [ ] Update monitoring parameters with new cylinder start pressure
- [ ] Log replacement in inventory management system
- [ ] Notify relevant lab members of cylinder change
- [ ] Schedule next replacement based on predicted depletion date

## Common Pitfalls

**Monitoring Setup Issues:**
- ❌ **Inconsistent reading times** → Daily variations affect trend accuracy
  - ✅ Take readings at same time each day (e.g., 9:00 AM ± 30 min)
  
- ❌ **Wrong consumption estimates** → Inaccurate depletion predictions
  - ✅ Calculate from actual usage over 2+ weeks; update seasonally
  
- ❌ **Ignoring temperature effects** → Pressure varies with ambient temperature
  - ✅ Allow cylinder to equilibrate to room temperature before reading
  
- ❌ **Not accounting for usage variations** → Weekend vs weekday consumption differs
  - ✅ Monitor separately for different usage patterns; use average

**Alert and Response Issues:**
- ❌ **Alert fatigue** → Too many notifications cause important alerts to be missed
  - ✅ Batch daily reports; only escalate urgent alerts immediately
  
- ❌ **Missing weekend alerts** → Friday check doesn't catch Saturday depletion
  - ✅ Always check weekend risk explicitly; use Friday 5 PM check
  
- ❌ **Delayed replacement** → Waiting too long leads to actual depletion
  - ✅ Replace when caution status triggered; don't wait for danger
  
- ❌ **No backup plan** → Cylinder fails with no replacement available
  - ✅ Maintain 1-2 backup cylinders; know emergency supplier contacts

**Calculation and Data Issues:**
- ❌ **Wrong cylinder capacity** → 10L vs 40L confusion causes 4x error
  - ✅ Always verify cylinder label; double-check capacity parameter
  
- ❌ **Pressure unit confusion** → PSI vs MPa or Bar mixing
  - ✅ Standardize on MPa; convert if gauge shows different units
  
- ❌ **Not tracking multiple cylinders** → Mixing readings from different tanks
  - ✅ Label cylinders clearly; use location-specific monitoring
  
- ❌ **Ignoring cumulative error** → Small daily errors compound over weeks
  - ✅ Verify predictions against actual depletion; calibrate regularly

**Operational Issues:**
- ❌ **Gauges not calibrated** → Inaccurate readings lead to wrong predictions
  - ✅ Calibrate pressure gauges annually or per manufacturer recommendation
  
- ❌ **Leaks undetected** → Higher consumption than predicted
  - ✅ Regular leak checks; sudden consumption increases indicate leaks
  
- ❌ **Regulator problems** → Pressure drops even with adequate gas
  - ✅ Replace regulators per schedule; check for ice buildup in flow
  
- ❌ **No documentation** → Cannot track trends or troubleshoot issues
  - ✅ Maintain detailed logs; review monthly for optimization

## Troubleshooting

**Problem: Predicted depletion date consistently wrong**
- Symptoms: Actual depletion 3-5 days earlier or later than predicted
- Causes:
  - Incorrect consumption rate estimate
  - Changing usage patterns (more/fewer cultures)
  - Temperature variations affecting pressure readings
  - Leaks in system
- Solutions:
  - Recalculate consumption rate from recent actual usage
  - Monitor for 2+ weeks to establish accurate baseline
  - Take readings at consistent temperature conditions
  - Check for leaks using soapy water at connections

**Problem: Frequent false alerts (alert fatigue)**
- Symptoms: Receiving caution/danger alerts that don't require action
- Causes:
  - Alert threshold too sensitive
  - Normal fluctuations triggering alerts
  - Multiple notifications for same cylinder
- Solutions:
  - Adjust alert_days parameter (increase from 2 to 3)
  - Implement alert aggregation (daily summary vs immediate)
  - Use quiet mode for automated checks; manual for full reports

**Problem: Weekend depletion not detected**
- Symptoms: Cylinder runs out Saturday/Sunday despite monitoring
- Causes:
  - Friday check missed weekend risk
  - Depletion spans multiple days
  - Holiday weekends not considered
- Solutions:
  - Add explicit Friday 5 PM check for weekend risk
  - Extend alert_days before long weekends
  - Use will_deplete_on_weekend() logic that checks multi-day periods

**Problem: Cannot read pressure gauge accurately**
- Symptoms: Inconsistent or unclear pressure readings
- Causes:
  - Gauge needle stuck or damaged
  - Condensation or dirt on gauge face
  - Parallax error reading needle position
- Solutions:
  - Replace faulty gauges immediately
  - Clean gauge face regularly
  - View needle straight-on to avoid parallax
  - Consider digital pressure sensors for better accuracy

**Problem: Cylinder depletes faster than expected**
- Symptoms: Predicted 10 days, actually depleted in 6 days
- Causes:
  - Increased incubator usage (more cultures, frequent door openings)
  - Gas leak in system
  - Regulator malfunction
  - Temperature increase (higher consumption)
- Solutions:
  - Check for leaks at all connections
  - Verify incubator door seals
  - Inspect regulator for proper function
  - Update consumption rate to reflect actual usage

**Problem: Monitoring script not running automatically**
- Symptoms: No daily logs or alerts despite cron setup
- Causes:
  - Cron job misconfigured
  - Path issues in script
  - Permissions problems
  - Script errors not logged
- Solutions:
  - Test cron job manually first
  - Use full absolute paths in cron and script
  - Check cron logs: `grep CRON /var/log/syslog`
  - Redirect stderr to log file for debugging

# Chemical Storage Sorter

Organize laboratory chemicals into safe storage groups based on chemical compatibility and hazard classification. Prevents dangerous reactions by identifying incompatible pairs and providing segregation guidelines compliant with OSHA, NFPA, and institutional safety standards.

**Key Capabilities:**
- **Automatic Chemical Classification**: Categorize chemicals into hazard groups (acids, bases, oxidizers, flammables, toxics)
- **Compatibility Checking**: Identify incompatible chemical pairs that could react dangerously if stored together
- **Storage Grouping**: Automatically sort chemical inventories into safe storage arrangements
- **Safety Warnings**: Generate warnings for incompatible storage combinations and hazardous interactions
- **Regulatory Compliance**: Follow standard chemical segregation rules per OSHA and NFPA guidelines

---

## When to Use

**✅ Use this skill when:**
- Setting up **new laboratory storage** systems and need to organize chemical inventory
- Preparing for **EHS (Environmental Health & Safety) inspections** or compliance audits
- **Relocating or reorganizing** an existing chemical storage area
- **Inventorying** chemicals and checking current storage arrangements for safety issues
- **Onboarding new lab members** and training them on chemical storage safety
- **Investigating chemical incidents** involving improper storage or reactions
- Creating **standard operating procedures** (SOPs) for chemical handling and storage

**❌ Do NOT use when:**
- Dealing with **unknown chemical compositions** or unlabeled containers → Contact EHS for proper identification first
- Needing **specific temperature requirements** for storage → Use specialized temperature monitoring tools
- Handling **radioactive materials** or biohazards → Follow specialized protocols for these materials
- Seeking **disposal instructions** for chemicals → Use `waste-disposal-guide` for disposal procedures
- Requiring **SDS (Safety Data Sheet) lookup** → Use `safety-data-sheet-reader` for detailed chemical information
- Planning **chemical inventory tracking** → Use `lab-inventory-tracker` for quantity and location tracking

**Related Skills:**
- **上游 (Upstream)**: `safety-data-sheet-reader`, `chemical-structure-converter`
- **下游 (Downstream)**: `lab-inventory-tracker`, `waste-disposal-guide`

---

## Integration with Other Skills

**Upstream Skills:**
- `safety-data-sheet-reader`: Retrieve chemical properties and hazard classifications from SDS
- `chemical-structure-converter`: Identify chemical class from structure or name for accurate categorization

**Downstream Skills:**
- `lab-inventory-tracker`: Record storage locations after chemicals are sorted and assigned
- `waste-disposal-guide`: Identify disposal requirements for incompatible chemicals that need to be removed
- `equipment-maintenance-log`: Track safety cabinet inspections and maintenance

**Complete Workflow:**
```
Chemical Inventory → safety-data-sheet-reader → chemical-storage-sorter → lab-inventory-tracker → Safe Storage
```

## Core Capabilities

### 1. Chemical Classification by Hazard Group

Automatically classify chemicals into standard hazard categories based on chemical name, formula, or keywords.

```python
from scripts.main import ChemicalStorageSorter

sorter = ChemicalStorageSorter()

# Classify individual chemicals
chemicals = [
    "Hydrochloric acid",
    "Sodium hydroxide",
    "Hydrogen peroxide 30%",
    "Ethanol",
    "Sodium chloride"
]

for chem in chemicals:
    group = sorter.classify_chemical(chem)
    print(f"{chem}: {group}")

# Output:
# Hydrochloric acid: acids
# Sodium hydroxide: bases
# Hydrogen peroxide 30%: oxidizers
# Ethanol: flammables
# Sodium chloride: general
```

**Hazard Groups:**

| Group | Examples | Key Hazards | Storage Requirements |
|-------|----------|-------------|---------------------|
| **Acids** | HCl, H₂SO₄, HNO₃, acetic acid | Corrosive, reactive | Acid cabinet, secondary containment |
| **Bases** | NaOH, KOH, ammonia, amines | Corrosive, caustic | Base cabinet, separate from acids |
| **Oxidizers** | H₂O₂, KMnO₄, nitrates, hypochlorites | Fire/explosion risk | Cool, dry, away from organics |
| **Flammables** | Ethanol, methanol, acetone, hexane | Fire hazard | Flammable storage cabinet |
| **Toxics** | Cyanides, mercury, arsenic compounds | Poison, bioaccumulation | Locked cabinet, limited access |
| **General** | NaCl, PBS, sucrose, glycerol | Low hazard | General storage |

**Classification Keywords:**

| Group | Keywords Triggers |
|-------|------------------|
| **Acids** | acid, hcl, sulfuric, nitric, acetic, citric, formic |
| **Bases** | hydroxide, naoh, koh, ammonia, amine, carbonate |
| **Flammables** | ethanol, methanol, acetone, ether, hexane, toluene, benzene |
| **Oxidizers** | peroxide, permanganate, hypochlorite, nitrate, chlorate, perchlorate |
| **Toxics** | cyanide, mercury, arsenic, lead, cadmium, thallium |

**Best Practices:**
- ✅ **Use full chemical names** for most accurate classification
- ✅ **Include concentration** when relevant (e.g., "hydrogen peroxide 30%" vs "3%")
- ✅ **Check ambiguous chemicals** manually if classification seems incorrect
- ✅ **Update keyword lists** for lab-specific chemicals not in default database

**Common Issues and Solutions:**

**Issue: Chemical not recognized**
- Symptom: Classified as "general" despite being hazardous
- Solution: Use more specific chemical name; add custom keywords for lab-specific compounds

**Issue: Misclassification of similar names**
- Symptom: "Sodium acetate" classified as acid due to "acet" keyword
- Solution: Check classification results; manually override if needed

### 2. Compatibility Checking Between Chemicals

Determine if two chemicals can be safely stored together without risk of dangerous reactions.

```python
from scripts.main import ChemicalStorageSorter

sorter = ChemicalStorageSorter()

# Check specific chemical pairs
pairs_to_check = [
    ("Hydrochloric acid", "Sodium hydroxide"),
    ("Ethanol", "Hydrogen peroxide"),
    ("Sodium chloride", "Potassium chloride"),
    ("Nitric acid", "Acetone")
]

for chem1, chem2 in pairs_to_check:
    compatible, message = sorter.check_compatibility(chem1, chem2)
    status = "✅ Compatible" if compatible else "❌ INCOMPATIBLE"
    print(f"{chem1} + {chem2}: {status}")
    if not compatible:
        print(f"   Warning: {message}")

# Output:
# Hydrochloric acid + Sodium hydroxide: ❌ INCOMPATIBLE
#    Warning: INCOMPATIBLE: acids cannot be stored with bases
# Ethanol + Hydrogen peroxide: ❌ INCOMPATIBLE
#    Warning: INCOMPATIBLE: flammables cannot be stored with oxidizers
# Sodium chloride + Potassium chloride: ✅ Compatible
# Nitric acid + Acetone: ❌ INCOMPATIBLE
```

**Incompatibility Matrix:**

| Chemical Group | Incompatible With | Reaction Risk |
|----------------|------------------|---------------|
| **Acids** | Bases, oxidizers, cyanides, sulfides | Violent neutralization, toxic gas generation |
| **Bases** | Acids, oxidizers, halogenated compounds | Heat generation, decomposition |
| **Oxidizers** | Flammables, acids, bases, reducing agents | Fire, explosion, violent reactions |
| **Flammables** | Oxidizers, acids | Fire, combustion enhancement |
| **Toxics** | Acids, oxidizers | Toxic gas release, increased hazard |

**Best Practices:**
- ✅ **Check all new chemicals** against existing storage before placement
- ✅ **Use minimum 3-foot separation** for incompatible groups
- ✅ **Consider secondary containment** for highly reactive pairs
- ✅ **Document exceptions** with engineering controls in place

**Common Issues and Solutions:**

**Issue: False positive compatibility**
- Symptom: Tool says compatible but chemicals actually react
- Causes: Missing specific incompatibility not in general rules
- Solution: Always consult SDS for specific incompatibilities; use this as first check only

**Issue: Ambiguous compatibility**
- Symptom: "Compatible with precautions" message for borderline cases
- Solution: Err on side of caution; store separately or consult EHS

### 3. Automated Storage Grouping

Sort an entire chemical inventory into safe storage groups based on hazard classifications.

```python
from scripts.main import ChemicalStorageSorter

sorter = ChemicalStorageSorter()

# Example lab inventory
inventory = [
    "Hydrochloric acid (conc.)",
    "Sodium hydroxide pellets",
    "Ethanol 95%",
    "Acetone",
    "Hydrogen peroxide 30%",
    "Potassium permanganate",
    "Sodium chloride",
    "PBS buffer",
    "Glycerol",
    "Sulfuric acid",
    "Ammonium hydroxide",
    "Methanol",
    "Hexane",
    "Mercury(II) chloride"
]

# Sort into storage groups
groups = sorter.sort_chemicals(inventory)

# Display results
for group, chemicals in groups.items():
    if chemicals:
        print(f"\n{group.upper()} STORAGE:")
        for chem in chemicals:
            print(f"  • {chem}")
```

**Storage Group Output:**
```
ACIDS STORAGE:
  • Hydrochloric acid (conc.)
  • Sulfuric acid

BASES STORAGE:
  • Sodium hydroxide pellets
  • Ammonium hydroxide

OXIDIZERS STORAGE:
  • Hydrogen peroxide 30%
  • Potassium permanganate

FLAMMABLES STORAGE:
  • Ethanol 95%
  • Acetone
  • Methanol
  • Hexane

TOXICS STORAGE:
  • Mercury(II) chloride

GENERAL STORAGE:
  • Sodium chloride
  • PBS buffer
  • Glycerol
```

**Best Practices:**
- ✅ **Sort alphabetically within groups** for easier location
- ✅ **Include concentration** in labels for diluted vs concentrated chemicals
- ✅ **Group by frequency of use** - most used chemicals most accessible
- ✅ **Reserve general storage** for the bulk of inventory (typically 60-70%)

**Common Issues and Solutions:**

**Issue: Chemical fits multiple categories**
- Symptom: Chemical has multiple hazards (e.g., concentrated HNO₃ is both acid and oxidizer)
- Solution: Store in most restrictive group (oxidizer cabinet for this example); check all incompatibilities

**Issue: Large inventory processing**
- Symptom: Hundreds of chemicals to sort
- Solution: Process in batches by lab area; export to spreadsheet for manual review

### 4. Storage Plan Generation with Safety Warnings

Generate a complete storage plan with specific warnings and segregation requirements.

```python
from scripts.main import ChemicalStorageSorter

sorter = ChemicalStorageSorter()

# Generate full storage plan
demo_inventory = [
    "HCl (concentrated)",
    "NaOH pellets",
    "Ethanol",
    "Hydrogen peroxide",
    "Sodium cyanide",
    "PBS",
    "Acetone"
]

groups = sorter.sort_chemicals(demo_inventory)
sorter.print_storage_plan(groups)
```

**Sample Output:**
```
============================================================
CHEMICAL STORAGE PLAN
============================================================

ACIDS STORAGE:
----------------------------------------
  • HCl (concentrated)
  ⚠️  Keep away from: bases, oxidizers, cyanides, sulfides

BASES STORAGE:
----------------------------------------
  • NaOH pellets
  ⚠️  Keep away from: acids, oxidizers, halogenated

OXIDIZERS STORAGE:
----------------------------------------
  • Hydrogen peroxide
  ⚠️  Keep away from: flammables, acids, bases, reducing

FLAMMABLES STORAGE:
----------------------------------------
  • Ethanol
  • Acetone
  ⚠️  Keep away from: oxidizers, acids

TOXICS STORAGE:
----------------------------------------
  • Sodium cyanide
  ⚠️  Keep away from: acids, oxidizers

GENERAL STORAGE:
----------------------------------------
  • PBS

============================================================
```

**Storage Requirements by Group:**

| Group | Cabinet Type | Ventilation | Special Requirements |
|-------|-------------|-------------|---------------------|
| **Acids** | Acid cabinet | Fume hood access | Secondary containment, corrosion-resistant |
| **Bases** | Base cabinet | Standard | Keep separate from acids (minimum 3 feet) |
| **Oxidizers** | Standard/oxidizer | Cool, dry location | Away from ignition sources |
| **Flammables** | Flammable cabinet | Explosion-proof | Bonding/grounding for dispensing |
| **Toxics** | Locked cabinet | Standard | Access log, limited quantities |
| **General** | Standard shelving | Standard | Standard lab storage |

**Best Practices:**
- ✅ **Post plan visibly** near storage areas
- ✅ **Update when chemicals are added/removed**
- ✅ **Include emergency contact info** on storage plan
- ✅ **Review quarterly** for accuracy

**Common Issues and Solutions:**

**Issue: Insufficient storage space**
- Symptom: Multiple groups needing same cabinet type
- Solution: Prioritize by hazard level; obtain additional cabinets if needed

**Issue: Chemicals with multiple incompatibilities**
- Symptom: One chemical incompatible with many others
- Solution: Isolate in separate location; consider reducing inventory

### 5. Batch Inventory Processing

Process large chemical inventories from files for comprehensive storage organization.

```python
from scripts.main import ChemicalStorageSorter
import json

def process_inventory_file(file_path: str) -> dict:
    """
    Process chemical inventory from text file.
    
    Expected format: One chemical per line
    """
    sorter = ChemicalStorageSorter()
    
    # Read inventory
    with open(file_path, 'r') as f:
        chemicals = [line.strip() for line in f if line.strip()]
    
    # Sort into groups
    groups = sorter.sort_chemicals(chemicals)
    
    # Calculate statistics
    stats = {
        'total_chemicals': len(chemicals),
        'groups': {group: len(items) for group, items in groups.items() if items},
        'hazardous_chemicals': sum(len(items) for group, items in groups.items() 
                                   if group != 'general' and items)
    }
    
    # Check for incompatibilities within current storage
    incompatibilities = []
    all_groups = list(groups.keys())
    
    for i, group1 in enumerate(all_groups):
        for group2 in all_groups[i+1:]:
            if group2 in sorter.COMPATIBILITY_GROUPS[group1]['incompatible']:
                if groups[group1] and groups[group2]:
                    incompatibilities.append({
                        'group1': group1,
                        'chemicals1': groups[group1],
                        'group2': group2,
                        'chemicals2': groups[group2]
                    })
    
    return {
        'groups': groups,
        'statistics': stats,
        'incompatibilities': incompatibilities
    }

# Example usage
# results = process_inventory_file('lab_inventory.txt')
# print(json.dumps(results, indent=2))
```

**Input File Format:**
```
# lab_inventory.txt
Hydrochloric acid (37%)
Sodium hydroxide
Ethanol (95%)
Acetone
Hydrogen peroxide (30%)
Potassium permanganate
Sodium chloride
Phosphate buffered saline
Glycerol
Sulfuric acid (conc.)
```

**Best Practices:**
- ✅ **Use standardized naming** in inventory files
- ✅ **Include concentrations** for diluted chemicals
- ✅ **Date the inventory** for tracking changes
- ✅ **Archive old versions** for historical reference

**Common Issues and Solutions:**

**Issue: Typos and inconsistent naming**
- Symptom: Same chemical listed multiple ways
- Solution: Standardize naming convention; use CAS numbers for ambiguous cases

**Issue: Concentration variations**
- Symptom: Multiple entries for "ethanol" at different concentrations
- Solution: Include concentration in name; store according to most hazardous concentration

### 6. Custom Classification Rules

Extend the classification system with lab-specific chemicals and custom rules.

```python
from scripts.main import ChemicalStorageSorter

class CustomChemicalSorter(ChemicalStorageSorter):
    """Extended sorter with lab-specific chemicals."""
    
    def __init__(self):
        super().__init__()
        # Add custom chemicals to groups
        self.COMPATIBILITY_GROUPS['acids']['examples'].extend([
            'trifluoroacetic acid',
            'trichloroacetic acid'
        ])
        
        self.COMPATIBILITY_GROUPS['flammables']['examples'].extend([
            'isopropanol',
            'isopropyl alcohol',
            '2-propanol'
        ])
        
        # Add custom keyword mappings
        self.custom_keywords = {
            'acids': ['tfa', 'tca'],
            'flammables': ['ipa', 'propanol']
        }
    
    def classify_chemical(self, name):
        """Override with custom keyword checking."""
        name_lower = name.lower()
        
        # Check custom keywords first
        for group, keywords in self.custom_keywords.items():
            if any(kw in name_lower for kw in keywords):
                return group
        
        # Fall back to parent classification
        return super().classify_chemical(name)

# Use custom sorter
custom_sorter = CustomChemicalSorter()
print(custom_sorter.classify_chemical("TFA"))  # Will classify as acid
print(custom_sorter.classify_chemical("IPA"))  # Will classify as flammable
```

**Best Practices:**
- ✅ **Document custom rules** in lab SOP
- ✅ **Share with all lab members** for consistency
- ✅ **Review periodically** for completeness
- ✅ **Update when new chemicals** are introduced

**Common Issues and Solutions:**

**Issue: Custom rules conflict with defaults**
- Symptom: Chemical classified differently than expected
- Solution: Check rule priority; custom rules should typically override defaults

**Issue: Too many custom chemicals**
- Symptom: Most chemicals need custom classification
- Solution: Update default database instead; contribute improvements upstream

## Common Patterns

### Pattern 1: New Lab Setup

**Scenario**: Setting up chemical storage for a new laboratory from scratch.

```json
{
  "setup_type": "new_lab",
  "space": "2 fume hoods, 3 acid cabinets, 2 flammable cabinets",
  "inventory_size": "~200 chemicals expected",
  "special_requirements": [
    "Cell culture focus - many biological buffers",
    "Molecular biology - EtBr, acrylamide",
    "Some organic synthesis - various solvents"
  ],
  "compliance": "OSHA, university EHS"
}
```

**Workflow:**
1. Inventory all chemicals before they arrive
2. Classify each chemical using this tool
3. Assign storage locations based on groups
4. Purchase appropriate cabinets (acid, flammable, etc.)
5. Label all storage areas clearly
6. Train all lab members on the system
7. Post emergency procedures and contact numbers

**Output Example:**
```
New Lab Storage Plan:

CABINET ASSIGNMENTS:
  Acid Cabinet #1: 12 acids
  Acid Cabinet #2: 8 oxidizers (also acids)
  Base Cabinet: 6 bases
  Flammable Cabinet #1: 15 solvents (ethanol, methanol, etc.)
  Flammable Cabinet #2: 8 other flammables
  Toxic Cabinet: 3 chemicals (EtBr, acrylamide, mercury salts)
  General Storage: 148 buffers, salts, reagents

SPACE UTILIZATION:
  Acid cabinets: 20/30 capacity (67%)
  Flammable: 23/40 capacity (58%)
  General: 148/200 capacity (74%)

RECOMMENDATION: Current space adequate for planned inventory
```

### Pattern 2: Safety Inspection Preparation

**Scenario**: Preparing for annual EHS safety inspection.

```json
{
  "inspection_type": "annual_ehs",
  "focus_areas": [
    "Chemical segregation compliance",
    "Incompatible storage checks",
    "Labeling and signage",
    "Secondary containment"
  ],
  "documentation_required": [
    "Chemical inventory",
    "Storage plan",
    "Incompatibility records"
  ]
}
```

**Workflow:**
1. Run full inventory through storage sorter
2. Check current storage against recommendations

Pre-Inspection Report:

✅ COMPLIANT STORAGE: 187/195 chemicals (95.9%)

⚠️  ISSUES IDENTIFIED:
  1. Acetic acid (glacial) stored with general chemicals
     → Move to acid cabinet
  2. Hydrogen peroxide near ethanol shelf
     → Move to oxidizer section
  3. Missing secondary containment for HCl
     → Add acid tray

📋 DOCUMENTATION READY:
  ✓ Chemical inventory (195 items)
  ✓ Storage plan (updated 2026-02-09)
  ✓ Incompatibility matrix (posted)
  ✓ Emergency contacts (current)

INSPECTION READINESS: 95% (2 chemicals need moving)
```

### Pattern 3: Chemical Relocation

**Scenario**: Moving chemicals to a new location or different lab.

```json
{
  "relocation_type": "lab_move",
  "from": "Building A, Room 301",
  "to": "Building B, Room 205",
  "chemicals_to_move": 150,
  "special_considerations": [
    "Some chemicals expire soon",
    "Unknown origin of 5 chemicals",
    "Need to dispose of 20 chemicals"
  ]
}
```

**Workflow:**
1. Inventory all chemicals at current location
2. Classify and sort all chemicals
3. Identify chemicals for disposal (expired, unknown, unneeded)
4. Plan packing by storage groups (pack together)
5. Ensure proper segregation during transport
6. Design storage layout at new location
7. Unpack directly into appropriate storage
8. Update inventory with new locations

**Output Example:**
```
Relocation Plan:

CHEMICALS TO MOVE: 130 items
  - Acids: 8 (pack together, upright)
  - Bases: 5 (pack together, separate from acids)
  - Flammables: 22 (DOT-approved containers)
  - Oxidizers: 6 (separate transport)
  - Toxics: 2 (locked container, manifest required)
  - General: 87 (standard boxes)

CHEMICALS TO DISPOSE: 20 items
  - Expired: 12
  - Unknown: 5
  - Unneeded: 3
  → Schedule waste pickup before move

PACKING SEQUENCE:
  Day 1: Dispose of waste chemicals
  Day 2: Pack general chemicals
  Day 3: Pack flammables and toxics
  Day 4: Transport and unpack
  Day 5: Final inventory at new location
```

### Pattern 4: Training New Lab Members

**Scenario**: Training new graduate students or technicians on chemical safety.

```json
{
  "training_type": "new_member_safety",
  "trainees": 3,
  "duration": "2 hours",
  "topics": [
    "Chemical hazard recognition",
    "Storage segregation rules",
    "Emergency procedures",
    "Finding chemicals in lab"
  ]
}
```

**Workflow:**
1. Introduce chemical hazard groups using this tool
2. Show real examples from lab inventory
3. Demonstrate compatibility checking
4. Practice classifying unknown chemicals
5. Tour actual storage areas
6. Quiz on incompatible pairs
7. Provide storage plan as reference
8. Document training completion

**Output Example:**
```
Training Session: Chemical Storage Safety

DEMONSTRATION EXAMPLES:
  1. Show classification: "ethanol" → flammable
  2. Show incompatibility: HCl + NaOH → violent reaction
  3. Show safe storage: PBS + NaCl → general storage together

INTERACTIVE QUIZ:
  Q: Can you store acetone near hydrogen peroxide?
  A: No - flammable + oxidizer = fire risk ✅
  
  Q: Where should concentrated HCl go?
  A: Acid cabinet with secondary containment ✅

HANDOUTS PROVIDED:
  ✓ Storage plan (current)
  ✓ Incompatibility matrix
  ✓ Emergency contact card
  ✓ SDS access instructions

TRAINING COMPLETE: 3/3 trainees passed quiz (100%)
```

## Common Pitfalls

**Classification Errors:**
- ❌ **Assuming dilute = safe** → Even dilute acids/bases need proper storage
  - ✅ Classify by chemical identity, not just concentration
  
- ❌ **Ignoring chemical name keywords** → Missing hazards in complex names
  - ✅ Check for multiple hazard indicators in chemical names
  
- ❌ **Not considering mixtures** → Commercial reagents may have multiple components
  - ✅ Check SDS for mixture compositions and store by most hazardous component
  
- ❌ **Classifying by use rather than hazard** → Storing buffer salts with acids
  - ✅ Always use hazard-based classification for storage

**Storage Arrangement Errors:**
- ❌ **Inadequate separation** → 6-inch gap instead of 3-foot minimum
  - ✅ Use physical barriers (cabinets) for incompatible groups
  
- ❌ **Storing by alphabetical order** → Acetic acid next to acetone
  - ✅ Always prioritize chemical compatibility over alphabetical order
  
- ❌ **Ignoring spill containment** → No secondary containment for liquids
  - ✅ Use trays or bunds for liquid chemicals, especially corrosives
  
- ❌ **Overcrowding cabinets** → Blocking access to emergency equipment
  - ✅ Maintain clear access to all chemicals and safety equipment

**Documentation Errors:**
- ❌ **Outdated storage plans** → Chemicals moved but map not updated
  - ✅ Update storage documentation whenever chemicals are relocated
  
- ❌ **Missing hazard warnings** → No incompatibility matrix posted
  - ✅ Post storage plan with clear hazard warnings
  
- ❌ **No training records** → Cannot prove safety training occurred
  - ✅ Document all safety training with signatures
  
- ❌ **Incomplete inventories** → Missing chemicals from tracking system
  - ✅ Maintain complete, up-to-date chemical inventory

**Operational Errors:**
- ❌ **Using food containers** → Chemicals stored in drink bottles
  - ✅ Use only appropriate chemical storage containers
  
- ❌ **No expiration monitoring** → Old peroxides or other degradables
  - ✅ Track expiration dates; dispose of expired chemicals promptly
  
- ❌ **Improper labeling** → Abbreviations or formulas only
  - ✅ Use full chemical names plus hazard symbols
  
- ❌ **Blocking access** → Storage in front of eyewash or shower
  - ✅ Maintain 3-foot clearance around all safety equipment

## Troubleshooting

**Problem: Chemical cannot be classified**
- Symptoms: Tool returns "general" for obviously hazardous chemical
- Causes:
  - Chemical name not in keyword database
  - Unusual or proprietary chemical name
  - Mixture with complex name
- Solutions:
  - Check SDS for proper chemical name and hazards
  - Use CAS number to look up chemical class
  - Consult with EHS for unusual chemicals
  - Add custom classification rule for lab-specific chemicals

**Problem: Too many "incompatible" pairs identified**
- Symptoms: Hundreds of incompatibilities in a small lab
- Causes:
  - Overly broad incompatibility rules
  - Chemicals already properly separated but flagged
  - Concentration not considered (dilute vs concentrated)
- Solutions:
  - Focus on actual storage arrangements, not theoretical incompatibilities
  - Check if chemicals are already properly segregated
  - Consider concentration exemptions (very dilute solutions)
  - Prioritize by hazard severity

**Problem: Storage space insufficient**
- Symptoms: More chemicals than available cabinet space
- Causes:
  - Inventory has grown over time
  - Improper disposal of old chemicals
  - Over-purchasing of chemicals
- Solutions:
  - Dispose of expired or unneeded chemicals
  - Share chemicals between labs when possible
  - Request additional storage equipment from EHS
  - Implement "just-in-time" purchasing for expensive chemicals
  - Consider chemical inventory reduction program

**Problem: Lab members resist new storage system**
- Symptoms: Chemicals found in wrong locations after reorganization
- Causes:
  - Inadequate training
  - System too complex
  - Old habits hard to break
- Solutions:
  - Provide clear, hands-on training
  - Make storage locations intuitive and convenient
  - Post visible storage maps at point of use
  - Gentle reminders and positive reinforcement
  - Regular audits with feedback

**Problem: Chemical reactions in storage**
- Symptoms: Evidence of reaction (discoloration, gas, heat, fumes)
- Causes:
  - Incompatible chemicals stored together
  - Degradation of unstable chemicals
  - Contamination during storage
- Solutions:
  - **Immediately evacuate area if fumes or heat**
  - Contact EHS for safe cleanup
  - Review storage arrangements to prevent recurrence
  - Check for other potentially affected chemicals
  - Document incident and lessons learned

**Problem: Cannot find chemical when needed**
- Symptoms: Chemical in inventory but not in expected location
- Causes:
  - Chemical moved but inventory not updated
  - Mislabeling or unclear labels
  - Inconsistent naming (acetic acid vs ethanoic acid)
- Solutions:
  - Update inventory immediately when chemicals are moved
  - Use standardized, full chemical names
  - Implement barcode or QR code tracking
  - Keep storage plan current and accessible
  - Regular inventory reconciliation
