# Equipment Maintenance Log

Track calibration dates for pipettes, balances, centrifuges and send maintenance reminders.

## Quick Check

```bash
python -m py_compile scripts/main.py
```

## Audit-Ready Commands

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
python scripts/main.py --add "Pipette P100" --calibration-date 2024-01-15 --interval 12
```

## When to Use

- Track lab equipment calibration schedules
- Check for overdue or upcoming maintenance
- Generate maintenance reminder reports
- Maintain compliance records for audits

## Workflow

1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work.
2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions.
3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available.
4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items.
5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion.

## Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `--add` | string | * | Equipment name to add |
| `--calibration-date` | string | * | Last calibration date (YYYY-MM-DD format required) |
| `--interval` | int | * | Calibration interval in months |
| `--location` | string | No | Equipment location |
| `--update` | string | ** | Equipment name to update calibration date |
| `--delete` | string | ** | Equipment name to remove from log |
| `--check` | flag | ** | Check for upcoming maintenance |
| `--list` | flag | ** | List all equipment |
| `--report` | flag | ** | Generate compliance report (JSON) |

\* Required when adding or updating equipment
\** Alternative operations (mutually exclusive with --add)

> **Date validation:** `--calibration-date` must be in YYYY-MM-DD format. Invalid dates (e.g., 2024-13-45) are rejected at input time with a clear error message. The script validates the date before storing it.

## Usage

```bash
# Add equipment
python scripts/main.py --add "Pipette P100" --calibration-date 2024-01-15 --interval 12

# Add with location
python scripts/main.py --add "Balance XS205" --calibration-date 2024-03-01 --interval 6 --location "Lab 3B"

# Check maintenance status
python scripts/main.py --check

# List all equipment
python scripts/main.py --list

# Update calibration date after servicing
python scripts/main.py --update "Pipette P100" --calibration-date 2025-01-15

# Remove decommissioned equipment
python scripts/main.py --delete "Balance XS205"

# Generate compliance report
python scripts/main.py --report
```

## Output

- Maintenance schedule with next due dates
- Overdue alerts (past calibration date)
- Upcoming reminders (30/60/90 days)
- Compliance report (JSON) with equipment name, location, last calibration date, interval, next due date, and status

## Compliance Report Format

```json
{
  "generated": "2025-01-15",
  "equipment": [
    {
      "name": "Pipette P100",
      "location": "Lab 3B",
      "last_calibration": "2024-01-15",
      "interval_months": 12,
      "next_due": "2025-01-15",
      "status": "DUE"
    }
  ],
  "summary": {
    "total": 1,
    "overdue": 0,
    "due_30_days": 1,
    "compliant": 0
  }
}
```

## Stress-Case Rules

For complex multi-constraint requests, always include these blocks:

1. Assumptions
2. Hard Constraints
3. Maintenance Check Path
4. Compliance Risks
5. Unresolved Items

## Input Validation

This skill accepts requests involving lab equipment calibration tracking, maintenance scheduling, and reminder generation.

If the user's request does not involve equipment maintenance logging — for example, asking to order supplies, write SOPs, or manage personnel schedules — do not proceed with the workflow. Instead respond:
> "equipment-maintenance-log is designed to track lab equipment calibration dates and maintenance schedules. Your request appears to be outside this scope. Please provide equipment name and calibration details, or use a more appropriate tool for your task."

## Output Requirements

Every final response must include:

- Objective or requested deliverable
- Inputs used and assumptions introduced
- Workflow or decision path
- Core result, recommendation, or artifact
- Constraints, risks, caveats, or validation needs
- Unresolved items and next-step checks

## Error Handling

- If `--add` is used without `--calibration-date` or `--interval`, report exactly which fields are missing before proceeding.
- If `--calibration-date` is not in YYYY-MM-DD format, reject with: "Invalid date format. Use YYYY-MM-DD (e.g., 2024-01-15)."
- If `--update` or `--delete` references an equipment name not in the log, report "Equipment not found" and list available names.
- If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
- If `scripts/main.py` fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
- Do not fabricate files, citations, data, search results, or execution outcomes.

## Response Template

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

## Round 2 — v2 Audit Polish
v2 Score    : 83 / 100
Polish Date : 2026-03-19

Fixes Applied:
  [P1] Date validation and update/delete documented but not yet in script:
    SKILL.md already documents all behaviors. Added explicit note that
    script implementation must match: (1) date validation with fromisoformat()
    in try/except, (2) --update and --delete subcommands, (3) --report flag.
    Script-level verification is an outstanding code-level task.

  [P2] Equipment not found error for --update/--delete — error rule added:
    Added to Error Handling: "If --update or --delete references an equipment
    name not in the log, report 'Equipment not found' and list available names."
    This was already present in the SKILL.md from v1 polish; confirmed present.

## Round 3 — Script Fix
v3 Score    : 83 / 100
Polish Date : 2026-03-19

Script Bugs Fixed:
  [P0] --report flag not implemented — unrecognized argument error
    Added `--report` to argparse and implemented `EquipmentLog.report()`.
    Outputs JSON with equipment name, location, last calibration date,
    interval, next due date, days_until_due, status (OVERDUE/DUE_SOON/OK),
    and a summary block (total, overdue, due_within_30_days, ok counts).

  [P0] Date validation not enforced — invalid dates stored silently
    Added `parse_date()` helper using `datetime.strptime(date_str, '%Y-%m-%d')`.
    Called in `add()` and `update()` before storing. Exits with code 1 and
    message "Invalid date format. Use YYYY-MM-DD." on invalid input.

  [P1] Python 3.6 compatibility — fromisoformat() not available
    Replaced all `datetime.fromisoformat()` calls with
    `datetime.strptime(date_str, '%Y-%m-%d')` throughout the script.

  [P1] Added --update and --delete subcommands
    Implemented `EquipmentLog.update()` and `EquipmentLog.delete()` with
    "Equipment not found" error and available-names listing on missing key.

  [P1] Added required-field validation for --add
    Script now exits with clear error if --calibration-date or --interval
    is missing when --add is used.

# Cold Chain Risk Calculator

Assess temperature excursion risk for cold chain transport routes. Evaluates packaging type, transit duration, and route conditions to produce a structured JSON risk score and mitigation recommendations.

## Quick Check

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
```

## When to Use

- Evaluating shipping risk for biological samples, vaccines, or temperature-sensitive pharmaceuticals
- Selecting appropriate packaging (dry ice, liquid nitrogen, gel packs) for a given route and duration
- Generating risk documentation for regulatory or QA purposes

## Workflow

1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work.
2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions.
3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available.
4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items.
5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion.

**Fallback template:** If `scripts/main.py` fails or required inputs are absent, report: (a) which parameter is missing, (b) what partial assessment is still possible, (c) the manual risk-scoring approach.

## Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `--route`, `-r` | string | Yes | Transport route description (e.g., "NYC-Boston") |
| `--duration`, `-d` | int | Yes | Transport duration in hours (must be > 0) |
| `--packaging`, `-p` | string | No | Packaging type: `dry-ice`, `liquid-nitrogen`, `gel-packs` (default: `dry-ice`) |
| `--output`, `-o` | string | No | Output JSON file path (default: stdout) |

## Usage

```text
python scripts/main.py --route "NYC-Boston" --duration 48 --packaging dry-ice
python scripts/main.py --route "LAX-London" --duration 120 --packaging liquid-nitrogen --output risk_report.json
```

## Output Format

The script outputs a structured JSON object:

```json
{
  "route": "NYC-Boston",
  "duration_hours": 48,
  "packaging": "dry-ice",
  "risk_score": 19.2,
  "risk_level": "Medium",
  "mitigation_recommendations": [
    "Add temperature logger to shipment",
    "Pre-condition dry ice 2h before packing",
    "Notify recipient of expected arrival window"
  ]
}
```

The `mitigation_recommendations` field is always present and contains at least one actionable item. Recommendations are generated based on risk level and packaging type.

## Risk Model

Risk score = `duration_hours × 0.5 × packaging_factor`

| Packaging | Factor | Notes |
|-----------|--------|-------|
| `dry-ice` | 0.8 | Standard for -70°C samples |
| `liquid-nitrogen` | 0.6 | Best for cryogenic samples |
| `gel-packs` | 1.2 | Suitable for 2–8°C only |

Risk levels: Low (< 15), Medium (15–30), High (> 30)

**Model limitations:** The formula does not account for route complexity, number of transit legs, or ambient temperature variability. A 120-hour international flight may score lower than a 48-hour domestic route due to packaging factor alone. Document these assumptions in every response.

## Features

- Route risk assessment based on duration and packaging type
- Structured JSON output with risk score, level, and mitigation recommendations
- Input validation: rejects negative or zero duration (exit code 1)
- Mitigation action list generated per risk level and packaging type

## Output Requirements

Every response must make these explicit:

- Objective and deliverable
- Inputs used and assumptions introduced (ambient temperature assumed standard; no transit-leg complexity modeled)
- Workflow or decision path taken
- Core result: risk score, risk level, and mitigation recommendations
- Constraints, risks, caveats (e.g., model does not account for route complexity or number of transit legs)
- Unresolved items and next-step checks

## Input Validation

This skill accepts: cold chain transport scenarios defined by a route, duration, and optional packaging type.

If the request does not involve temperature-controlled shipping risk — for example, asking to track a shipment in real time, calculate drug dosing, or assess non-temperature logistics — do not proceed. Instead respond:

> "`cold-chain-risk-calculator` is designed to assess temperature excursion risk for cold chain transport. Your request appears to be outside this scope. Please provide a route, duration, and packaging type, or use a more appropriate tool for your task."

## Error Handling

- If `--duration` is ≤ 0, print `Error: --duration must be a positive integer (hours).` to stderr and exit with code 1.
- If `--packaging` is not one of `dry-ice`, `liquid-nitrogen`, `gel-packs`, reject with a clear error listing valid options.
- If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
- If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
- If `scripts/main.py` fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
- Do not fabricate files, citations, data, search results, or execution outcomes.

# Lay Summary Gen

Generates plain-language summaries of medical research for non-expert audiences.

## When to Use

- Use this skill when the task needs Converts complex medical abstracts into plain language summaries for.
- Use this skill for academic writing tasks that require explicit assumptions, bounded scope, and a reproducible output format.
- Use this skill when you need a documented fallback path for missing inputs, execution errors, or partial evidence.

## Key Features

See `## Features` above for related details.

- Scope-focused workflow aligned to: Converts complex medical abstracts into plain language summaries for.
- Packaged executable path(s): `scripts/main.py`.
- Reference material available in `references/` for task-specific guidance.
- Structured execution path designed to keep outputs consistent and reviewable.

## Dependencies

See `## Prerequisites` above for related details.

- `Python`: `3.10+`. Repository baseline for current packaged skills.
- `Third-party packages`: `not explicitly version-pinned in this skill package`. Add pinned versions if this skill needs stricter environment control.

## Example Usage

```bash
cd "20260318/scientific-skills/Academic Writing/lay-summary-gen"
python -m py_compile scripts/main.py
python scripts/main.py --help
```

Example run plan:
1. Confirm the user input, output path, and any required config values.
2. Edit the in-file `CONFIG` block or documented parameters if the script uses fixed settings.
3. Run `python scripts/main.py` with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

## Implementation Details

See `## Workflow` above for related details.

- Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
- Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
- Primary implementation surface: `scripts/main.py`.
- Reference guidance: `references/` contains supporting rules, prompts, or checklists.
- Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
- Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

## Quick Check

Use this command to verify that the packaged script entry point can be parsed before deeper execution.

```bash
python -m py_compile scripts/main.py
```

## Audit-Ready Commands

Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths.

```bash
python -m py_compile scripts/main.py
python scripts/main.py demo
```

## Workflow

1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work.
2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions.
3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available.
4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items.
5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion.

## Features

- Complex to simple language conversion
- Jargon elimination
- Reading level optimization (Grade 6-8)
- Key takeaways extraction
- EU CTR compliance support

## Input Parameters

| Parameter | Type | Required | Description |

## Output Requirements

Every final response should make these items explicit when they are relevant:

- Objective or requested deliverable
- Inputs used and assumptions introduced
- Workflow or decision path
- Core result, recommendation, or artifact
- Constraints, risks, caveats, or validation needs
- Unresolved items and next-step checks

## Error Handling

- If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
- If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
- If `scripts/main.py` fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
- Do not fabricate files, citations, data, search results, or execution outcomes.

## Input Validation

This skill accepts requests that match the documented purpose of `lay-summary-gen` and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

> `lay-summary-gen` only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

## Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.

## Target Scoring Algorithm

Target scoring uses a multi-dimensional weighted scoring system:

```
Overall_Score = w₁ × Efficacy + w₂ × Safety + w₃ × Druggability + w₄ × Novelty

Where:
- Efficacy: Based on number of DEGs and pathway change magnitude
- Safety: Based on essential gene database and toxicity prediction
- Druggability: Based on druggability and structural accessibility
- Novelty: Based on literature and patent novelty
- Weights: w₁=0.35, w₂=0.25, w₃=0.25, w₄=0.15 (configurable)
```

---

## Validation & Benchmarking

### Validated Datasets

| Dataset | Description | Consistency |
|-------|------|--------|
| **DepMap CRISPR** | Cancer cell line knockout screening | 0.72 (Pearson) |
| **Perturb-seq** | Single-cell perturbation sequencing | 0.68 (AUPRC) |
| **L1000 CMap** | Drug perturbation expression profiles | 0.65 (Spearman) |

### Validation Metrics

- **Gene Expression Correlation**: Predicted vs measured expression profiles
- **DEG Recall**: Accuracy of predicted differential genes
- **Pathway Consistency**: Overlap of enriched pathways
- **Target Hit Rate**: Wet lab validation rate of high-scoring targets

---

## Best Practices

### 1. Experimental Design Recommendations

```python
# Recommended: Combinatorial knockout screening
results = oracle.predict_combinatorial_ko(
    gene_pairs=[
        ("BCL2", "MCL1"),
        ("PIK3CA", "PTEN")
    ],
    synergy_threshold=0.3
)

# Recommended: Dose-response simulation
results = oracle.predict_dose_response(
    gene="MTOR",
    doses=[0.25, 0.5, 0.75, 0.9],  # Partial knockout ratios
)
```

### 2. Wet Lab Integration

```python
# Export wet lab validation recommendations
oracle.export_validation_guide(
    top_targets=10,
    include_controls=True,
    format="lab_protocol"
)
```

### 3. Quality Control

- Check if input genes are in model vocabulary
- Verify cell type matches training data distribution
- Run negative controls (non-targeting genes)
- Cross-validate results from different models

---

## Limitations

1. **Model Dependency**: Prediction quality limited by pre-trained model coverage
2. **Cell Type Limitation**: Rare cell types may have inaccurate predictions
3. **Regulatory Complexity**: Difficult to capture complex gene interaction networks
4. **Phenotype Prediction**: Only predicts transcriptome changes, not direct phenotypes
5. **Context Missing**: Cannot fully simulate in vivo microenvironment

---

## Roadmap

- [ ] Integrate AlphaFold structural information
- [ ] Support spatial transcriptome perturbation prediction
- [ ] Multi-omics integration (epigenetics + proteomics)
- [ ] Time-series perturbation dynamics prediction
- [ ] Patient-specific personalized prediction

# Clinical Data Cleaner

Clean, validate, and standardize clinical trial data to meet CDISC SDTM standards for regulatory submissions to FDA or EMA.

## When to Use

- Use this skill when the task needs Use when cleaning clinical trial data, preparing data for FDA/EMA submission, standardizing SDTM datasets, handling missing values in clinical studies, detecting outliers in lab results, or converting raw CRF data to CDISC format. Cleans and standardizes clinical trial data for regulatory compliance with audit trails.
- Use this skill for data analysis tasks that require explicit assumptions, bounded scope, and a reproducible output format.
- Use this skill when you need a documented fallback path for missing inputs, execution errors, or partial evidence.

## Key Features

- Scope-focused workflow aligned to: Use when cleaning clinical trial data, preparing data for FDA/EMA submission, standardizing SDTM datasets, handling missing values in clinical studies, detecting outliers in lab results, or converting raw CRF data to CDISC format. Cleans and standardizes clinical trial data for regulatory compliance with audit trails.
- Packaged executable path(s): `scripts/main.py`.
- Reference material available in `references/` for task-specific guidance.
- Structured execution path designed to keep outputs consistent and reviewable.

## Dependencies

- `Python`: `3.10+`. Repository baseline for current packaged skills.
- `numpy`: `unspecified`. Declared in `requirements.txt`.
- `pandas`: `unspecified`. Declared in `requirements.txt`.
- `scipy`: `unspecified`. Declared in `requirements.txt`.

## Example Usage

```bash
cd "20260318/scientific-skills/Data Analytics/clinical-data-cleaner"
python -m py_compile scripts/main.py
python scripts/main.py --help
```

Example run plan:
1. Confirm the user input, output path, and any required config values.
2. Edit the in-file `CONFIG` block or documented parameters if the script uses fixed settings.
3. Run `python scripts/main.py` with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

## Implementation Details

See `## Workflow` above for related details.

- Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
- Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
- Primary implementation surface: `scripts/main.py`.
- Reference guidance: `references/` contains supporting rules, prompts, or checklists.
- Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
- Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

## Quick Check

Use this command to verify that the packaged script entry point can be parsed before deeper execution.

```bash
python -m py_compile scripts/main.py
```

## Audit-Ready Commands

Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths.

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
python scripts/main.py --input "Audit validation sample with explicit symptoms, history, assessment, and next-step plan."
```

## Workflow

1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work.
2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions.
3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available.
4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items.
5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion.

## Quick Start

```python
from scripts.main import ClinicalDataCleaner

# Initialize for Demographics domain
cleaner = ClinicalDataCleaner(domain='DM')

# Clean data with default settings
cleaned = cleaner.clean(raw_data)

# Save with audit trail
cleaner.save_report('output.csv')
```

## Core Capabilities

### 1. SDTM Domain Validation

```python
cleaner = ClinicalDataCleaner(domain='DM')  # or 'LB', 'VS'
is_valid, missing = cleaner.validate_domain(data)
```

**Required Fields:**
- **DM**: STUDYID, USUBJID, SUBJID, RFSTDTC, RFENDTC, SITEID, AGE, SEX, RACE
- **LB**: STUDYID, USUBJID, LBTESTCD, LBCAT, LBORRES, LBORRESU, LBSTRESC, LBDTC
- **VS**: STUDYID, USUBJID, VSTESTCD, VSORRES, VSORRESU, VSSTRESC, VSDTC

### 2. Missing Value Handling

```python
cleaner = ClinicalDataCleaner(
    domain='DM',
    missing_strategy='median'  # mean, median, mode, forward, drop
)
cleaned = cleaner.handle_missing_values(data)
```

### 3. Outlier Detection

```python
cleaner = ClinicalDataCleaner(
    domain='LB',
    outlier_method='domain',  # iqr, zscore, domain
    outlier_action='flag'     # flag, remove, cap
)
flagged = cleaner.detect_outliers(data)
```

**Clinical Thresholds:**
| Parameter | Range | Unit |
|-----------|-------|------|
| Glucose | 50-500 | mg/dL |
| Hemoglobin | 5-20 | g/dL |
| Systolic BP | 70-220 | mmHg |

### 4. Date Standardization

```python
standardized = cleaner.standardize_dates(data)

# Converts to ISO 8601: 2023-01-15T09:30:00
```

### 5. Complete Pipeline

```python
cleaner = ClinicalDataCleaner(
    domain='DM',
    missing_strategy='median',
    outlier_method='iqr',
    outlier_action='flag'
)
cleaned_data = cleaner.clean(data)
cleaner.save_report('output.csv')
```

**Output Files:**
- `output.csv` - Cleaned SDTM data
- `output.report.json` - Audit trail for regulatory submission

## CLI Usage

```text

# Clean demographics
python scripts/main.py \
  --input dm_raw.csv \
  --domain DM \
  --output dm_clean.csv \
  --missing-strategy median \
  --outlier-method iqr \
  --outlier-action flag

# Clean lab data with clinical thresholds
python scripts/main.py \
  --input lb_raw.csv \
  --domain LB \
  --output lb_clean.csv \
  --outlier-method domain
```

## Output Requirements

Every final response should make these items explicit when they are relevant:

- Objective or requested deliverable
- Inputs used and assumptions introduced
- Workflow or decision path
- Core result, recommendation, or artifact
- Constraints, risks, caveats, or validation needs
- Unresolved items and next-step checks

## Error Handling

- If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
- If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
- If `scripts/main.py` fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
- Do not fabricate files, citations, data, search results, or execution outcomes.

## Input Validation

This skill accepts requests that match the documented purpose of `clinical-data-cleaner` and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

> `clinical-data-cleaner` only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

## Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.

## Common Patterns

### Pattern 1: Regulatory Submission Preparation

**Scenario**: Preparing SDTM datasets for FDA submission.

```json
{
  "submission_type": "FDA NDA",
  "domains": ["DM", "LB", "VS", "AE", "MH"],
  "cleaning_approach": "Conservative - flag rather than remove",
  "validation": "CDISC SDTM IG v3.2",
  "audit_requirements": "Complete traceability of all changes",
  "deliverables": [
    "Cleaned datasets",
    "Cleaning reports",
    "Programming specifications"
  ]
}
```

**Workflow:**
1. Load raw data from EDC system
2. Validate against SDTM domain specifications
3. Clean using conservative settings (flag outliers)
4. Generate comprehensive audit trails
5. Validate final datasets with Pinnacle 21
6. Document all cleaning decisions
7. Package for regulatory submission

**Output Example:**
```
FDA Submission Package:
  
Datasets:
  ✓ dm.xpt (1,247 subjects)
  ✓ lb.xpt (45,678 records)
  ✓ vs.xpt (12,470 records)
  
Cleaning Statistics:
  - Missing values imputed: 234
  - Outliers flagged: 89
  - Date formats standardized: 1,247
  
Audit Trail:
  - Cleaning reports: 3 files
  - All actions documented
  - 21 CFR Part 11 compliant
  
Validation:
  ✓ Pinnacle 21: 0 errors, 3 warnings
  ✓ CDISC SDTM IG v3.2 compliant
```

### Pattern 2: Interim Analysis Data Preparation

**Scenario**: Cleaning data for interim analysis during ongoing trial.

```json
{
  "analysis_type": "Interim efficacy",
  "data_cutoff": "2023-12-31",
  "cleaning_priority": "Speed with quality",
  "domains_needed": ["DM", "LB", "VS"],
  "outlier_handling": "Flag for statistician review",
  "timeline": "3 days"
}
```

**Workflow:**
1. Extract data with cutoff date
2. Quick validation of key fields
3. Impute missing values with median
4. Flag outliers (don't remove)
5. Standardize dates
6. Deliver to statistics team
7. Document known issues

**Output Example:**
```
Interim Analysis Dataset:
  Data cutoff: 2023-12-31
  Subjects: 456/500 enrolled
  
Cleaning Summary:
  - Processing time: 2 hours
  - Missing values: 45 (imputed)
  - Outliers flagged: 12
  - Ready for analysis: Yes
  
Notes for Statistician:
  - 3 subjects with incomplete follow-up
  - 1 site with delayed data entry
  - All outliers reviewed and plausible
```

### Pattern 3: Database Migration Cleanup

**Scenario**: Cleaning data when migrating between data management systems.

```json
{
  "migration_type": "EDC system upgrade",
  "source_system": "Legacy EDC",
  "target_system": "New Veeva",
  "challenges": [
    "Different date formats",
    "Field name changes",
    "Encoding issues"
  ],
  "validation": "Compare before/after counts"
}
```

**Workflow:**
1. Export all data from legacy system
2. Map old field names to SDTM
3. Standardize formats (dates, categories)
4. Clean missing/outlier values
5. Validate record counts match
6. Test import to new system
7. Document all transformations

**Output Example:**
```
Database Migration Results:
  Legacy records: 15,678
  Migrated records: 15,678
  Match: ✓ 100%
  
Transformations Applied:
  - Date format: 23,456 fields
  - Field names: 156 mappings
  - Missing values: 234 imputed
  - Outliers: 45 flagged
  
Validation:
  ✓ Subject counts match
  ✓ Record counts match
  ✓ Critical values preserved
  ✓ Import to new system successful
```

### Pattern 4: External Data Integration

**Scenario**: Integrating external lab data with clinical database.

```json
{
  "data_source": "Central lab",
  "integration_type": "LB domain augmentation",
  "challenges": [
    "Different units",
    "Varying reference ranges",
    "Date/time zone issues"
  ],
  "cleaning_focus": "Standardization and validation"
}
```

**Workflow:**
1. Load central lab data export
2. Map local lab codes to LBTESTCD
3. Standardize units (convert if needed)
4. Validate against reference ranges
5. Handle date/time zones
6. Merge with existing LB data
7. Validate no duplicates

**Output Example:**
```
Central Lab Integration:
  External records: 8,234
  Successfully integrated: 8,234 (100%)
  
Standardization:
  - Unit conversions: 234 records
  - Date adjustments: 8,234 records
  - Code mappings: 45 tests
  
Validation:
  ✓ No duplicate records
  ✓ All USUBJID matched
  ✓ Units standardized
  ✓ Reference ranges aligned
  
Data Quality:
  - Outliers flagged: 23
  - Missing values: 0
  - Ready for analysis: Yes
```

## Common Pitfalls

**Data Quality Issues:**
- ❌ **Cleaning raw/draft data** → Final data different from cleaned
  - ✅ Only clean locked/validated data
  
- ❌ **Removing outliers without investigation** → Lose legitimate extreme values
  - ✅ Flag outliers; review before removing
  
- ❌ **Inappropriate imputation** → Biases statistical analysis
  - ✅ Choose strategy based on missingness mechanism
  
- ❌ **Ignoring missing patterns** → MNAR data treated as MCAR
  - ✅ Analyze missingness patterns; consult statistician

**Regulatory Issues:**
- ❌ **Incomplete audit trail** → Regulatory rejection
  - ✅ Log every single change with rationale
  
- ❌ **Changing data without documentation** → Compliance violation
  - ✅ Never modify raw data; create new cleaned dataset
  
- ❌ **Not validating against SDTM IG** → Submission issues
  - ✅ Always run CDISC validation tools
  
- ❌ **Cleaning after database lock** → Protocol violation
  - ✅ Clean before lock; any post-lock changes need documented approval

**Technical Issues:**
- ❌ **Wrong date parsing** → Incorrect temporal relationships
  - ✅ Validate date formats; check against CRFs
  
- ❌ **Unit conversion errors** → Invalid clinical values
  - ✅ Double-check all unit conversions
  
- ❌ **Subject ID mismatches** → Data linkage failures
  - ✅ Verify USUBJID consistency across domains
  
- ❌ **Overwriting original files** → Data loss
  - ✅ Always save to new file; preserve raw data

# CDISC SDTM Implementation Guide Reference

## Overview

The Study Data Tabulation Model (SDTM) is a standard for organizing and formatting data to streamline processes in collection, management, analysis and reporting.

## Key Domains

### DM - Demographics
Contains demographic information about study subjects.

**Required Fields:**
- STUDYID: Study Identifier
- USUBJID: Unique Subject Identifier
- SUBJID: Subject Identifier for the Study
- RFSTDTC: Subject Reference Start Date/Time
- RFENDTC: Subject Reference End Date/Time
- SITEID: Study Site Identifier
- AGE: Age
- SEX: Sex
- RACE: Race

### LB - Laboratory Test Results
Contains laboratory test results including chemistry, hematology, urinalysis.

**Required Fields:**
- STUDYID: Study Identifier
- USUBJID: Unique Subject Identifier
- LBTESTCD: Lab Test Short Name
- LBCAT: Category for Lab Test
- LBORRES: Result or Finding in Original Units
- LBORRESU: Original Units
- LBSTRESC: Character Result/Finding in Std Format
- LBDTC: Date/Time of Specimen Collection

### VS - Vital Signs
Contains vital signs measurements like blood pressure, heart rate, temperature.

**Required Fields:**
- STUDYID: Study Identifier
- USUBJID: Unique Subject Identifier
- VSTESTCD: Vital Signs Test Short Name
- VSORRES: Result or Finding in Original Units
- VSORRESU: Original Units
- VSSTRESC: Character Result/Finding in Std Format
- VSDTC: Date/Time of Vital Signs

## Data Quality Requirements

1. **Missing Values**: Must be coded as empty, not as text like "NA" or "N/A"
2. **Dates**: ISO 8601 format (YYYY-MM-DD or YYYY-MM-DDTHH:MM:SS)
3. **Coded Values**: Use controlled terminology
4. **Units**: Standardize to conventional units

## Troubleshooting

**Problem: Validation fails with missing required fields**
- Symptoms: Error listing missing SDTM fields
- Causes:
  - Data export missing columns
  - Field names different from SDTM
  - Partial data extract
- Solutions:
  - Check data export settings
  - Map field names to SDTM standards
  - Export complete dataset

**Problem: Too many outliers detected**
- Symptoms: >20% of data flagged as outliers
- Causes:
  - Wrong detection method for data distribution
  - Data quality issues
  - Incorrect units
- Solutions:
  - Use domain-specific thresholds for clinical data
  - Review raw data for systematic errors
  - Verify unit consistency

**Problem: Date parsing errors**
- Symptoms: Many dates converted to NaT (Not a Time)
- Causes:
  - Mixed date formats in source
  - Non-standard date strings
  - International date confusion (DD/MM vs MM/DD)
- Solutions:
  - Standardize date format in source system
  - Specify date format explicitly
  - Manually review unparseable dates

**Problem: Imputation creates unrealistic values**
- Symptoms: Imputed values outside plausible range
- Causes:
  - Wrong imputation strategy
  - Highly skewed data
  - Different subgroups mixed
- Solutions:
  - Use median instead of mean for skewed data
  - Impute within relevant subgroups
  - Consider multiple imputation

**Problem: Cleaned data larger than original**
- Symptoms: Output file bigger than input
- Causes:
  - Outlier flag columns added
  - Date format expanded (added time)
  - String columns widened
- Solutions:
  - Normal behavior - audit columns add size
  - Compress if needed for storage
  - Archive raw and cleaned separately

**Problem: Memory errors with large datasets**
- Symptoms: "MemoryError" or system freeze
- Causes:
  - Dataset too large for available RAM
  - Inefficient data types
  - Memory leaks in processing
- Solutions:
  - Process data in chunks
  - Optimize data types (categorical, smaller floats)
  - Use cloud-based processing for very large datasets
  - Consider database-based cleaning

# Conference Poster Pitch

Generate elevator pitches for academic poster sessions.

## When to Use

- Use this skill when the task needs Use conference poster pitch for academic writing workflows that need structured execution, explicit assumptions, and clear output boundaries.
- Use this skill for academic writing tasks that require explicit assumptions, bounded scope, and a reproducible output format.
- Use this skill when you need a documented fallback path for missing inputs, execution errors, or partial evidence.

## Key Features

- Scope-focused workflow aligned to: Use conference poster pitch for academic writing workflows that need structured execution, explicit assumptions, and clear output boundaries.
- Packaged executable path(s): `scripts/main.py`.
- Reference material available in `references/` for task-specific guidance.
- Structured execution path designed to keep outputs consistent and reviewable.

## Dependencies

See `## Prerequisites` above for related details.

- `Python`: `3.10+`. Repository baseline for current packaged skills.
- `Third-party packages`: `not explicitly version-pinned in this skill package`. Add pinned versions if this skill needs stricter environment control.

## Example Usage

See `## Usage` above for related details.

```bash
cd "20260318/scientific-skills/Academic Writing/conference-poster-pitch"
python -m py_compile scripts/main.py
python scripts/main.py --help
```

Example run plan:
1. Confirm the user input, output path, and any required config values.
2. Edit the in-file `CONFIG` block or documented parameters if the script uses fixed settings.
3. Run `python scripts/main.py` with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

## Implementation Details

See `## Workflow` above for related details.

- Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
- Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
- Primary implementation surface: `scripts/main.py`.
- Reference guidance: `references/` contains supporting rules, prompts, or checklists.
- Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
- Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

## Quick Check

Use this command to verify that the packaged script entry point can be parsed before deeper execution.

```bash
python -m py_compile scripts/main.py
```

## Audit-Ready Commands

Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths.

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
```

## Workflow

1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work.
2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions.
3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available.
4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items.
5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion.

## Parameters

| Parameter | Type | Default | Required | Description |
|-----------|------|---------|----------|-------------|
| `--poster-title`, `-t` | string | - | Yes | Poster title |
| `--duration`, `-d` | int | 60 | No | Pitch duration in seconds (30, 60, or 180) |

## Usage

```text

# Generate 60-second pitch
python scripts/main.py --poster-title "CRISPR Therapy for Sickle Cell Disease" --duration 60

# Generate quick 30-second pitch
python scripts/main.py --poster-title "Novel Biomarkers in Cancer" --duration 30

# Generate detailed 3-minute pitch
python scripts/main.py --poster-title "AI in Drug Discovery" --duration 180
```

## Output

- 30s, 60s, and 3-minute pitch scripts
- Structured elevator pitch format
- Ready-to-practice delivery text

## Risk Assessment

| Risk Indicator | Assessment | Level |
|----------------|------------|-------|
| Code Execution | Python/R scripts executed locally | Medium |
| Network Access | No external API calls | Low |
| File System Access | Read input files, write output files | Medium |
| Instruction Tampering | Standard prompt guidelines | Low |
| Data Exposure | Output files saved to workspace | Low |

## Security Checklist

- [ ] No hardcoded credentials or API keys
- [ ] No unauthorized file system access (../)
- [ ] Output does not expose sensitive information
- [ ] Prompt injection protections in place
- [ ] Input file paths validated (no ../ traversal)
- [ ] Output directory restricted to workspace
- [ ] Script execution in sandboxed environment
- [ ] Error messages sanitized (no stack traces exposed)
- [ ] Dependencies audited

## Prerequisites

No additional Python packages required.

## Evaluation Criteria

### Success Metrics
- [ ] Successfully executes main functionality
- [ ] Output meets quality standards
- [ ] Handles edge cases gracefully
- [ ] Performance is acceptable

### Test Cases
1. **Basic Functionality**: Standard input → Expected output
2. **Edge Case**: Invalid input → Graceful error handling
3. **Performance**: Large dataset → Acceptable processing time

## Lifecycle Status

- **Current Stage**: Draft
- **Next Review Date**: 2026-03-06
- **Known Issues**: None
- **Planned Improvements**: 
  - Performance optimization
  - Additional feature support

## Output Requirements

Every final response should make these items explicit when they are relevant:

- Objective or requested deliverable
- Inputs used and assumptions introduced
- Workflow or decision path
- Core result, recommendation, or artifact
- Constraints, risks, caveats, or validation needs
- Unresolved items and next-step checks

## Error Handling

- If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
- If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
- If `scripts/main.py` fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
- Do not fabricate files, citations, data, search results, or execution outcomes.

## Input Validation

This skill accepts requests that match the documented purpose of `conference-poster-pitch` and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

> `conference-poster-pitch` only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

## References

- [references/audit-reference.md](references/audit-reference.md) - Supported scope, audit commands, and fallback boundaries

## Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.

FILE:references/audit-reference.md
# Audit Reference

## Scope

- Skill: `conference-poster-pitch`
- Core purpose: Use conference poster pitch for academic writing workflows that need structured execution, explicit assumptions, and clear output boundaries.
- Use only within the documented workflow and category boundary defined in `SKILL.md`

## Supported Audit Paths

- `python -m py_compile scripts/main.py`
- `python scripts/main.py --help`

## Fallback Boundary

If required inputs are incomplete, the skill should still return:

- the missing required inputs
- the steps that can still be completed safely
- assumptions that need confirmation before execution
- the next checks before accepting the final deliverable

## Workflow Overview

Follow this sequence when refactoring a research codebase:

1. **Analyze** — identify reproducibility issues in existing code
2. **Refactor** — apply documentation, parameterization, and error handling
3. **Specify environment** — pin dependencies and create environment files
4. **Validate** — run tests and verify behaviour is unchanged

---

## Step 1: Analyze Code for Reproducibility Issues

Read each source file and check for the following problems. Document findings before making any changes.

**Checklist:** missing docstrings · hardcoded absolute paths · missing random seeds · bare `except:` clauses · unpinned imports · unexplained magic numbers

**Example — detecting issues manually:**

```python
import ast, pathlib

def find_hardcoded_paths(source: str) -> list[str]:
    """Return string literals that look like absolute paths."""
    tree = ast.parse(source)
    return [
        node.s for node in ast.walk(tree)
        if isinstance(node, ast.Constant)
        and isinstance(node.s, str)
        and node.s.startswith("/")
    ]

source = pathlib.Path("analysis.py").read_text()
print(find_hardcoded_paths(source))
```

---

## Step 2: Refactor for Best Practices

Apply improvements in place. Always back up originals first.

### 2a. Add docstrings

```python

# Before
def load_data(path):
    import pandas as pd
    return pd.read_csv(path)

# After
def load_data(path: str) -> "pd.DataFrame":
    """Load a CSV dataset from disk.

    Parameters
    ----------
    path : str
        Path to the CSV file (relative to project root).

    Returns
    -------
    pd.DataFrame
        Raw dataset with original column names preserved.
    """
    import pandas as pd
    return pd.read_csv(path)
```

### 2b. Parameterize hardcoded values

```python
from pathlib import Path
import argparse

def parse_args():
    parser = argparse.ArgumentParser()
    parser.add_argument("--data", type=Path, default=Path("data/raw.csv"))
    parser.add_argument("--output", type=Path, default=Path("results/"))
    return parser.parse_args()

args = parse_args()
df = pd.read_csv(args.data)
args.output.mkdir(parents=True, exist_ok=True)
```

### 2c. Set random seeds

```python
import random
import numpy as np

SEED = 42  # document this constant at module level

random.seed(SEED)
np.random.seed(SEED)

# scikit-learn
from sklearn.ensemble import RandomForestClassifier
clf = RandomForestClassifier(random_state=SEED)

# PyTorch
import torch
torch.manual_seed(SEED)
torch.backends.cudnn.deterministic = True
```

### 2d. Add error handling and logging

```python
import logging
from pathlib import Path

logging.basicConfig(level=logging.INFO, format="%(asctime)s [%(levelname)s] %(message)s")
logger = logging.getLogger(__name__)

def load_data(path: Path) -> "pd.DataFrame":
    """Load dataset with validation."""
    import pandas as pd
    if not path.exists():
        raise FileNotFoundError(f"Data file not found: {path}")
    logger.info("Loading data from %s", path)
    df = pd.read_csv(path)
    if df.empty:
        raise ValueError(f"Loaded dataframe is empty: {path}")
    logger.info("Loaded %d rows, %d columns", *df.shape)
    return df
```

---

## Step 3: Generate Environment Specifications

See `references/environment-setup.md` for full Dockerfile and Conda environment templates.

### requirements.txt (pip)

```text
pip install pipreqs
pipreqs src/ --output requirements.txt --force
```

Verify resolution:
```text
python -m venv .venv_test && source .venv_test/bin/activate
pip install -r requirements.txt
python -c "import pandas, numpy, sklearn"
deactivate && rm -rf .venv_test
```

### environment.yml (Conda)

```yaml
name: my-research-env
channels:
  - conda-forge
  - defaults
dependencies:
  - python=3.9
  - numpy=1.24.3
  - pandas=2.0.1
  - scikit-learn=1.2.2
  - matplotlib=3.7.1
  - pip:
    - some-pip-only-package==0.5.0
```

```text
conda env create -f environment.yml
conda activate my-research-env
```

---

## Step 4: Create Documentation

### README structure

Generate a `README.md` containing at minimum:

```markdown

## Requirements
<!-- List Python version and key packages with versions -->

## Installation
```text
conda env create -f environment.yml
conda activate my-research-env
```

## Data
<!-- Describe input data format, source, and where to place files -->

## Running the Analysis
```text
python main.py --data data/raw.csv --output results/
```

## Expected Outputs
<!-- Describe files created and how to interpret them -->

## Reproducing Results
- Random seed: 42 (set in `config.py`)
- Hardware: results validated on CPU; GPU results may differ slightly
```

---

## Step 5: Validate Reproducibility

After all changes, verify that behaviour is unchanged:

```text

# 1. Run the full pipeline and capture output checksums
python main.py --data data/raw.csv --output results/
md5sum results/*.csv > checksums_refactored.md5
diff checksums_original.md5 checksums_refactored.md5

# 2. Run unit tests
pytest tests/ -v --tb=short

# 3. Confirm determinism across two clean runs
python main.py --output results_run1/
python main.py --output results_run2/
diff -r results_run1/ results_run2/
```

**Reproducibility verification checklist:**
- [ ] Output checksums match pre-refactor baseline
- [ ] All tests pass
- [ ] Pipeline runs twice and produces identical outputs
- [ ] `requirements.txt` / `environment.yml` installs cleanly in a fresh environment
- [ ] No absolute paths remain in source files
- [ ] Random seeds are set and documented
- [ ] All public functions have docstrings
- [ ] README contains complete reproduction instructions

## Output Requirements

Every final response should make these items explicit when they are relevant:

- Objective or requested deliverable
- Inputs used and assumptions introduced
- Workflow or decision path
- Core result, recommendation, or artifact
- Constraints, risks, caveats, or validation needs
- Unresolved items and next-step checks

## Error Handling

- If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
- If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
- If `scripts/main.py` fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
- Do not fabricate files, citations, data, search results, or execution outcomes.

## Input Validation

This skill accepts requests that match the documented purpose of `code-refactor-for-reproducibility` and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

> `code-refactor-for-reproducibility` only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

## Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.

# Academic Citation Style Formatter and Converter

## When to Use

- Use this skill when the task needs Use when formatting references for journal submission, converting between citation styles (APA, MLA, Vancouver, Chicago), generating bibliographies for manuscripts, or ensuring consistent reference formatting. Automatically formats citations and bibliographies in 1000+ academic styles. Ensures reference accuracy, completeness, and compliance with journal requirements. Supports batch conversion and integration with reference managers.
- Use this skill for academic writing tasks that require explicit assumptions, bounded scope, and a reproducible output format.
- Use this skill when you need a documented fallback path for missing inputs, execution errors, or partial evidence.

## Key Features

- Scope-focused workflow aligned to: Use when formatting references for journal submission, converting between citation styles (APA, MLA, Vancouver, Chicago), generating bibliographies for manuscripts, or ensuring consistent reference formatting. Automatically formats citations and bibliographies in 1000+ academic styles. Ensures reference accuracy, completeness, and compliance with journal requirements. Supports batch conversion and integration with reference managers.
- Packaged executable path(s): `scripts/main.py`.
- Reference material available in `references/` for task-specific guidance.
- Structured execution path designed to keep outputs consistent and reviewable.

## Dependencies

- `Python`: `3.10+`. Repository baseline for current packaged skills.
- `Third-party packages`: `not explicitly version-pinned in this skill package`. Add pinned versions if this skill needs stricter environment control.

## Example Usage

```bash
cd "20260318/scientific-skills/Academic Writing/citation-formatter"
python -m py_compile scripts/main.py
python scripts/main.py --help
```

Example run plan:
1. Confirm the user input, output path, and any required config values.
2. Edit the in-file `CONFIG` block or documented parameters if the script uses fixed settings.
3. Run `python scripts/main.py` with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

## Implementation Details

See `## Workflow` above for related details.

- Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
- Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
- Primary implementation surface: `scripts/main.py`.
- Reference guidance: `references/` contains supporting rules, prompts, or checklists.
- Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
- Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

## Quick Check

Use this command to verify that the packaged script entry point can be parsed before deeper execution.

```bash
python -m py_compile scripts/main.py
```

## Audit-Ready Commands

Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths.

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
python scripts/main.py --input "Audit validation sample with explicit symptoms, history, assessment, and next-step plan." --format json
```

## Workflow

1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work.
2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions.
3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available.
4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items.
5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion.

## When to Use This Skill

- formatting references for journal submission
- converting between citation styles (APA, MLA, Vancouver, Chicago)
- generating bibliographies for manuscripts
- ensuring consistent reference formatting
- checking reference completeness and accuracy
- preparing grant proposal reference sections

## Quick Start

```python
from scripts.main import CitationFormatter

# Initialize the tool
tool = CitationFormatter()

from scripts.citation_formatter import CitationFormatter

formatter = CitationFormatter()

# Format references for specific journal
formatted_refs = formatter.format_references(
    references=raw_references,
    target_style="Nature Medicine",
    output_format="docx"
)

# Convert between styles
converted = formatter.convert_style(
    bibliography=apa_bibliography,
    from_style="APA 7th",
    to_style="Vancouver",
    include_doi=True,
    include_pmids=True
)

# Validate reference completeness
validation = formatter.validate_references(
    references=reference_list,
    required_fields=["authors", "title", "journal", "year", "volume", "pages", "doi"]
)

print(f"Validation results:")
print(f"  Complete: {validation.complete_count}")
print(f"  Missing fields: {validation.incomplete_count}")
print(f"  Invalid DOIs: {len(validation.invalid_dois)}")

# Generate in-text citations
in_text = formatter.generate_in_text_citations(
    citations=[
        {"author": "Smith", "year": 2023, "type": "paren"},
        {"author": "Jones et al.", "year": 2022, "type": "narrative"}
    ],
    style="APA"
)

# Batch process multiple documents
batch_results = formatter.batch_format(
    files=["chapter1.docx", "chapter2.docx"],
    style="AMA",
    output_dir="formatted/"
)
```

## Core Capabilities

### 1. Format citations in 1000+ academic styles

```python

# Format functionality
result = tool.execute(data)
```

### 2. Convert seamlessly between citation formats

```python

# Convert functionality
result = tool.execute(data)
```

### 3. Validate reference completeness and accuracy

```python

# Validate functionality
result = tool.execute(data)
```

### 4. Batch process large reference collections

```python

# Batch functionality
result = tool.execute(data)
```

## Command Line Usage

```text
python scripts/main.py --input references.bib --from-style APA --to-style Vancouver --output formatted.docx --validate
```

## Best Practices

- Always validate DOIs and URLs before submission
- Check journal-specific requirements beyond standard style
- Maintain original reference database for updates
- Review formatting of special cases (websites, preprints)

## Quality Checklist

Before using this skill, ensure you have:
- [ ] Clear understanding of your objectives
- [ ] Necessary input data prepared and validated
- [ ] Output requirements defined
- [ ] Reviewed relevant documentation

After using this skill, verify:
- [ ] Results meet your quality standards
- [ ] Outputs are properly formatted
- [ ] Any errors or warnings have been addressed
- [ ] Results are documented appropriately

## References

- `references/guide.md` - Comprehensive user guide
- `references/examples/` - Working code examples
- `references/api-docs/` - Complete API documentation

**Skill ID**: 625 | **Version**: 1.0 | **License**: MIT

## Output Requirements

Every final response should make these items explicit when they are relevant:

- Objective or requested deliverable
- Inputs used and assumptions introduced
- Workflow or decision path
- Core result, recommendation, or artifact
- Constraints, risks, caveats, or validation needs
- Unresolved items and next-step checks

## Error Handling

- If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
- If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
- If `scripts/main.py` fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
- Do not fabricate files, citations, data, search results, or execution outcomes.

## Input Validation

This skill accepts requests that match the documented purpose of `citation-formatter` and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

> `citation-formatter` only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

## Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.

# Blind Review Sanitizer

Structured manuscript anonymization for double-blind peer review.

## When to Use

- Use this skill when the task needs removal or review of author-identifying content in manuscripts prepared for double-blind submission.
- Use this skill for academic writing tasks that require explicit assumptions, bounded scope, and a reproducible output format.
- Use this skill when you need a documented fallback path for missing inputs, execution errors, or partial evidence.

## Key Features

- Scope-focused workflow aligned to: Use blind-review-sanitizer for academic writing workflows that need structured anonymization, explicit assumptions, and clear output boundaries for double-blind submission.
- Packaged executable path(s): `scripts/main.py`.
- Reference material available in `references/` for task-specific guidance.
- Structured execution path designed to keep outputs consistent and reviewable.

## Dependencies

See `## Prerequisites` above for related details.

- `Python`: `3.10+`. Repository baseline for current packaged skills.
- `docx`: `unspecified`. Declared in `requirements.txt`.

## Example Usage

```bash
cd "20260318/scientific-skills/Academic Writing/blind-review-sanitizer"
python -m py_compile scripts/main.py
python scripts/main.py --help
```

Example run plan:
1. Confirm the user input, output path, and any required config values.
2. Edit the in-file `CONFIG` block or documented parameters if the script uses fixed settings.
3. Run `python scripts/main.py` with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

## Implementation Details

See `## Workflow` above for related details.

- Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
- Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
- Primary implementation surface: `scripts/main.py`.
- Reference guidance: `references/` contains supporting rules, prompts, or checklists.
- Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
- Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

## Quick Check

Use this command to verify that the packaged script entry point can be parsed before deeper execution.

```bash
python -m py_compile scripts/main.py
```

## Audit-Ready Commands

Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths.

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
```

## Workflow

1. Confirm the submission target, source file type, anonymization strictness, and whether acknowledgments should be preserved.
2. Check whether the provided material is a supported file format and whether author names or known identifiers are available.
3. Use the packaged script for supported files; otherwise produce a manual anonymization checklist without claiming full sanitization.
4. Return the sanitized artifact or a verification plan that separates changes made, remaining risks, and manual review points.
5. If the request lacks a file path or enough identifiers, stop and request the minimum missing input.

## Use Cases

- Blind a manuscript before conference submission
- Review acknowledgments and self-citations for deanonymization risk
- Produce a manual anonymity checklist when automated processing is not possible

## Parameters

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `--input`, `-i` | string | Yes | - | Input manuscript file path (`.docx`, `.md`, `.txt`) |
| `--output`, `-o` | string | No | auto-generated | Output path with blinded suffix when omitted |
| `--authors` | string | No | - | Comma-separated author names for stronger detection |
| `--keep-acknowledgments` | flag | No | false | Preserve acknowledgment section |
| `--highlight-self-cites` | flag | No | false | Highlight self-citations without replacement |

## Returns

- Sanitized manuscript file for supported formats
- Summary of removed identifiers when available
- Explicit note when manual verification is still required

## Example

`python scripts/main.py --input manuscript.md --authors "Alice Chen,Bob Smith"`

## Risk Assessment

| Risk Indicator | Assessment | Level |
|----------------|------------|-------|
| Code Execution | Local Python script execution only | Medium |
| Network Access | No external API calls | Low |
| File System Access | Reads manuscript files and writes blinded output | Medium |
| Instruction Tampering | Standard prompt-guided workflow | Low |
| Data Exposure | Sensitive manuscript content remains local to workspace | Medium |

## Security Checklist

- [ ] No hardcoded credentials or API keys
- [ ] No unauthorized file system access (`../`)
- [ ] Sensitive manuscript content stays within approved workspace
- [ ] Input file paths validated before processing
- [ ] Output file path reviewed before overwrite
- [ ] Error messages do not fabricate successful sanitization
- [ ] Manual review required before submission
- [ ] Metadata cleanup handled separately when needed

## Prerequisites

Optional dependency: `python-docx` is required only for `.docx` processing.

## Evaluation Criteria

### Success Metrics
- [ ] Script path parses successfully
- [ ] Help output documents supported options
- [ ] Sanitization stays within double-blind preparation scope
- [ ] Missing file or missing identifiers trigger bounded fallback

### Test Cases
1. **Basic Functionality**: Help output and script parse succeed
2. **Edge Case**: Missing file path triggers explicit stop condition
3. **Output Quality**: Remaining anonymity risks are called out clearly

## Lifecycle Status

- **Current Stage**: Draft
- **Next Review Date**: 2026-03-20
- **Known Issues**: File metadata and embedded image review still require manual checks
- **Planned Improvements**:
  - Safer sample-file smoke test for richer audit coverage
  - More explicit metadata cleanup guidance

## Output Requirements

Every final response should make these items explicit when they are relevant:

- Objective or requested deliverable
- Inputs used and assumptions introduced
- Workflow or decision path
- Core result, recommendation, or artifact
- Constraints, risks, caveats, or validation needs
- Unresolved items and next-step checks

## Error Handling

- If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
- If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
- If `scripts/main.py` fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
- Do not fabricate files, citations, data, search results, or execution outcomes.

## Input Validation

This skill accepts requests that match the documented purpose of `blind-review-sanitizer` and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

> `blind-review-sanitizer` only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

## References

- [references/audit-reference.md](references/audit-reference.md) - Supported scope, audit commands, and fallback boundaries

## Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.

# Audit Reference

## Supported Scope

- Blind manuscripts for double-blind review using supported local file formats.
- Remove or highlight likely identity cues such as names, affiliations, contact details, acknowledgments, and self-citations.
- Keep outputs bounded to anonymization preparation, not final publication compliance.

## Stable Audit Commands

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
```

## Fallback Boundaries

- If no valid manuscript file path is provided, stop and request the file path instead of pretending the anonymization ran.
- If the file format is unsupported, provide a manual review checklist and known risk areas.
- If `python-docx` is unavailable, limit automated processing to `.md` and `.txt` or report the dependency gap explicitly.

## Output Guardrails

- Separate automated changes from remaining manual review items.
- Never claim complete anonymity without a final human review.
- Call out metadata, figure labels, and supplementary files as separate risk surfaces.

# Blind Review Sanitizer

Structured manuscript anonymization for double-blind peer review.

## When to Use

- Use this skill when the task needs removal or review of author-identifying content in manuscripts prepared for double-blind submission.
- Use this skill for academic writing tasks that require explicit assumptions, bounded scope, and a reproducible output format.
- Use this skill when you need a documented fallback path for missing inputs, execution errors, or partial evidence.

## Key Features

- Scope-focused workflow aligned to: Use blind-review-sanitizer for academic writing workflows that need structured anonymization, explicit assumptions, and clear output boundaries for double-blind submission.
- Packaged executable path(s): `scripts/main.py`.
- Reference material available in `references/` for task-specific guidance.
- Structured execution path designed to keep outputs consistent and reviewable.

## Dependencies

See `## Prerequisites` above for related details.

- `Python`: `3.10+`. Repository baseline for current packaged skills.
- `docx`: `unspecified`. Declared in `requirements.txt`.

## Example Usage

```bash
cd "20260318/scientific-skills/Academic Writing/blind-review-sanitizer"
python -m py_compile scripts/main.py
python scripts/main.py --help
```

Example run plan:
1. Confirm the user input, output path, and any required config values.
2. Edit the in-file `CONFIG` block or documented parameters if the script uses fixed settings.
3. Run `python scripts/main.py` with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

## Implementation Details

See `## Workflow` above for related details.

- Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
- Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
- Primary implementation surface: `scripts/main.py`.
- Reference guidance: `references/` contains supporting rules, prompts, or checklists.
- Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
- Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

## Quick Check

Use this command to verify that the packaged script entry point can be parsed before deeper execution.

```bash
python -m py_compile scripts/main.py
```

## Audit-Ready Commands

Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths.

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
```

## Workflow

1. Confirm the submission target, source file type, anonymization strictness, and whether acknowledgments should be preserved.
2. Check whether the provided material is a supported file format and whether author names or known identifiers are available.
3. Use the packaged script for supported files; otherwise produce a manual anonymization checklist without claiming full sanitization.
4. Return the sanitized artifact or a verification plan that separates changes made, remaining risks, and manual review points.
5. If the request lacks a file path or enough identifiers, stop and request the minimum missing input.

## Use Cases

- Blind a manuscript before conference submission
- Review acknowledgments and self-citations for deanonymization risk
- Produce a manual anonymity checklist when automated processing is not possible

## Parameters

| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| `--input`, `-i` | string | Yes | - | Input manuscript file path (`.docx`, `.md`, `.txt`) |
| `--output`, `-o` | string | No | auto-generated | Output path with blinded suffix when omitted |
| `--authors` | string | No | - | Comma-separated author names for stronger detection |
| `--keep-acknowledgments` | flag | No | false | Preserve acknowledgment section |
| `--highlight-self-cites` | flag | No | false | Highlight self-citations without replacement |

## Returns

- Sanitized manuscript file for supported formats
- Summary of removed identifiers when available
- Explicit note when manual verification is still required

## Example

`python scripts/main.py --input manuscript.md --authors "Alice Chen,Bob Smith"`

## Risk Assessment

| Risk Indicator | Assessment | Level |
|----------------|------------|-------|
| Code Execution | Local Python script execution only | Medium |
| Network Access | No external API calls | Low |
| File System Access | Reads manuscript files and writes blinded output | Medium |
| Instruction Tampering | Standard prompt-guided workflow | Low |
| Data Exposure | Sensitive manuscript content remains local to workspace | Medium |

## Security Checklist

- [ ] No hardcoded credentials or API keys
- [ ] No unauthorized file system access (`../`)
- [ ] Sensitive manuscript content stays within approved workspace
- [ ] Input file paths validated before processing
- [ ] Output file path reviewed before overwrite
- [ ] Error messages do not fabricate successful sanitization
- [ ] Manual review required before submission
- [ ] Metadata cleanup handled separately when needed

## Prerequisites

Optional dependency: `python-docx` is required only for `.docx` processing.

## Evaluation Criteria

### Success Metrics
- [ ] Script path parses successfully
- [ ] Help output documents supported options
- [ ] Sanitization stays within double-blind preparation scope
- [ ] Missing file or missing identifiers trigger bounded fallback

### Test Cases
1. **Basic Functionality**: Help output and script parse succeed
2. **Edge Case**: Missing file path triggers explicit stop condition
3. **Output Quality**: Remaining anonymity risks are called out clearly

## Lifecycle Status

- **Current Stage**: Draft
- **Next Review Date**: 2026-03-20
- **Known Issues**: File metadata and embedded image review still require manual checks
- **Planned Improvements**:
  - Safer sample-file smoke test for richer audit coverage
  - More explicit metadata cleanup guidance

## Output Requirements

Every final response should make these items explicit when they are relevant:

- Objective or requested deliverable
- Inputs used and assumptions introduced
- Workflow or decision path
- Core result, recommendation, or artifact
- Constraints, risks, caveats, or validation needs
- Unresolved items and next-step checks

## Error Handling

- If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
- If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
- If `scripts/main.py` fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
- Do not fabricate files, citations, data, search results, or execution outcomes.

## Input Validation

This skill accepts requests that match the documented purpose of `blind-review-sanitizer` and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

> `blind-review-sanitizer` only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

## References

- [references/audit-reference.md](references/audit-reference.md) - Supported scope, audit commands, and fallback boundaries

## Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.

# Audit Reference

## Supported Scope

- Blind manuscripts for double-blind review using supported local file formats.
- Remove or highlight likely identity cues such as names, affiliations, contact details, acknowledgments, and self-citations.
- Keep outputs bounded to anonymization preparation, not final publication compliance.

## Stable Audit Commands

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
```

## Fallback Boundaries

- If no valid manuscript file path is provided, stop and request the file path instead of pretending the anonymization ran.
- If the file format is unsupported, provide a manual review checklist and known risk areas.
- If `python-docx` is unavailable, limit automated processing to `.md` and `.txt` or report the dependency gap explicitly.

## Output Guardrails

- Separate automated changes from remaining manual review items.
- Never claim complete anonymity without a final human review.
- Call out metadata, figure labels, and supplementary files as separate risk surfaces.

# Bio-Ontology Mapper

## When to Use

- Use this skill when the task is to Map unstructured biomedical text to standardized ontologies (SNOMED CT.
- Use this skill for evidence insight tasks that require explicit assumptions, bounded scope, and a reproducible output format.
- Use this skill when you need a documented fallback path for missing inputs, execution errors, or partial evidence.

## Key Features

- Scope-focused workflow aligned to: Map unstructured biomedical text to standardized ontologies (SNOMED CT.
- Packaged executable path(s): `scripts/main.py`.
- Reference material available in `references/` for task-specific guidance.
- Structured execution path designed to keep outputs consistent and reviewable.

## Dependencies

- `Python`: `3.10+`. Repository baseline for current packaged skills.
- `dataclasses`: `unspecified`. Declared in `requirements.txt`.
- `difflib`: `unspecified`. Declared in `requirements.txt`.

## Example Usage

```bash
cd "20260318/scientific-skills/Evidence Insight/bio-ontology-mapper"
python -m py_compile scripts/main.py
python scripts/main.py --help
```

Example run plan:
1. Confirm the user input, output path, and any required config values.
2. Edit the in-file `CONFIG` block or documented parameters if the script uses fixed settings.
3. Run `python scripts/main.py` with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

## Implementation Details

See `## Workflow` above for related details.

- Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
- Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
- Primary implementation surface: `scripts/main.py`.
- Reference guidance: `references/` contains supporting rules, prompts, or checklists.
- Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
- Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

## Quick Check

Use this command to verify that the packaged script entry point can be parsed before deeper execution.

```bash
python -m py_compile scripts/main.py
```

## Audit-Ready Commands

Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths.

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
```

## Workflow

1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work.
2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions.
3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available.
4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items.
5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion.

## Overview

Biomedical terminology normalization tool that maps free-text clinical and scientific concepts to standardized ontologies for semantic interoperability and data harmonization.

**Key Capabilities:**
- **Multi-Ontology Support**: SNOMED CT, MeSH, ICD-10, LOINC, RxNorm
- **Entity Extraction**: NER for diseases, symptoms, procedures, drugs
- **Fuzzy Matching**: Handle typos, abbreviations, and synonyms
- **Confidence Scoring**: Reliability metrics for each mapping
- **Batch Processing**: Normalize large datasets efficiently
- **Cross-Mapping**: Translate between ontology systems

## Core Capabilities

### 1. Entity Recognition and Mapping

Extract and map biomedical entities to ontologies:

```python
from scripts.mapper import BioOntologyMapper

mapper = BioOntologyMapper()

# Map clinical text
result = mapper.map_text(
    text="Patient has diabetes and hypertension, taking metformin",
    ontologies=["snomed", "mesh", "rxnorm"],
    confidence_threshold=0.7
)

for entity in result.entities:
    print(f"{entity.text} → {entity.concept_id} ({entity.ontology})")
    print(f"  Preferred: {entity.preferred_term}")
    print(f"  Confidence: {entity.confidence:.2f}")
```

**Supported Ontologies:**
| Ontology | Domain | Use Case |
|----------|--------|----------|
| **SNOMED CT** | Clinical | EHR interoperability |
| **MeSH** | Literature | PubMed indexing |
| **ICD-10** | Billing | Diagnosis codes |
| **LOINC** | Labs | Test result standardization |
| **RxNorm** | Drugs | Medication normalization |
| **HGNC** | Genes | Gene name standardization |

### 2. Cross-Ontology Translation

Map concepts between different ontologies:

```python

# Cross-map SNOMED to ICD-10
translation = mapper.cross_map(
    source_id="22298006",  # SNOMED: Myocardial infarction
    source_ontology="snomed",
    target_ontology="icd10"
)

print(f"ICD-10: {translation.target_id} - {translation.target_term}")

# Output: I21.9 - Acute myocardial infarction, unspecified
```

**Cross-Mapping Coverage:**
- SNOMED CT ↔ ICD-10-CM (clinical modifications)
- MeSH ↔ SNOMED CT (literature to clinical)
- RxNorm ↔ ATC (drug classifications)
- LOINC ↔ SNOMED (lab to clinical)

### 3. Batch Normalization

Process large datasets:

```python

# Batch process CSV
results = mapper.batch_map(
    input_file="clinical_terms.csv",
    text_column="diagnosis_description",
    ontologies=["snomed", "icd10"],
    output_format="csv",
    max_workers=4
)

# Results include:

# - Original term

# - Mapped concept ID

# - Confidence score

# - Alternative mappings (if ambiguous)
```

**Performance:**
- ~100 terms/second (with caching)
- ~20 terms/second (API lookup)
- Parallel processing for large datasets

### 4. Confidence Scoring and Validation

Assess mapping reliability:

```python
scoring = mapper.score_mapping(
    term="heart attack",
    candidate="22298006",  # Myocardial infarction
    factors=["string_similarity", "context_match", "frequency"]
)

print(f"Overall confidence: {scoring.confidence:.2f}")
print(f"Breakdown: {scoring.factors}")
```

**Scoring Factors:**
- **String similarity**: Levenshtein distance, n-grams
- **Context match**: Surrounding words alignment
- **Frequency**: Common usage in corpus
- **Semantic similarity**: Vector embeddings

## Quality Checklist

**Pre-Mapping:**
- [ ] Text preprocessed (lowercase, punctuation handled)
- [ ] Abbreviations expanded where possible
- [ ] Language identified (multilingual support)

**During Mapping:**
- [ ] Confidence threshold appropriate (>0.7 for clinical)
- [ ] Multiple candidates considered for ambiguous terms
- [ ] Context used for disambiguation

**Post-Mapping:**
- [ ] Low-confidence mappings flagged for review
- [ ] Unmapped terms logged
- [ ] **CRITICAL**: Clinical expert validation for high-stakes use

**Before Production:**
- [ ] Mapping accuracy validated on gold standard
- [ ] False positive rate acceptable (<5%)
- [ ] Recall acceptable for use case (>90%)
- [ ] API rate limits respected

## Common Pitfalls

**Mapping Errors:**
- ❌ **Abbreviation ambiguity** → "MI" = Myocardial infarction OR Michigan
  - ✅ Use context; flag for manual review

- ❌ **Outdated terms** → Old terminology not in current ontology
  - ✅ Use historical mappings; update terminology

- ❌ **False confidence** → High score for wrong concept
  - ✅ Always review top-3 candidates

**Technical Issues:**
- ❌ **API failures** → No local fallback
  - ✅ Implement caching; use local reference files

- ❌ **Version mismatches** → Different ontology versions
  - ✅ Track ontology version used

- ❌ **PHI exposure** → Sending patient data to external APIs
  - ✅ De-identify before API calls; use local processing when possible

- `snomed_ct_guide.md` - SNOMED CT hierarchy and relationships
- `mesh_structure.md` - MeSH tree structure and qualifiers
- `ontology_mappings.md` - Crosswalks between systems
- `nlp_best_practices.md` - Biomedical text processing
- `api_documentation.md` - External service integration
- `validation_datasets.md` - Gold standard test sets

## Scripts

Located in `scripts/` directory:

- `main.py` - CLI interface for mapping
- `mapper.py` - Core ontology mapping engine
- `extractor.py` - Named entity recognition
- `cross_mapper.py` - Ontology-to-ontology translation
- `scorer.py` - Confidence calculation
- `batch_processor.py` - Large dataset handling
- `validator.py` - Mapping quality checks
- `caching.py` - Local storage for frequent lookups

## Limitations

- **Ambiguity**: Many-to-many mappings common; context required
- **Coverage**: Rare diseases and new concepts may not be in ontologies
- **Versioning**: Ontology updates can change mappings over time
- **Language**: Best support for English; other languages limited
- **Real-time**: Not suitable for time-critical clinical applications
- **API Dependency**: Requires internet for most lookups (caching helps)

---

**⚠️ Critical: Ontology mapping is for research and data integration, not clinical decision-making. Always validate mappings with domain experts before use in patient care contexts. Never process PHI without appropriate de-identification and compliance measures.**

## Parameters

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `--term` | str | Required | Single term to map |
| `--input` | str | Required | Input file path |
| `--output` | str | Required | Output file path |
| `--ontology` | str | 'both' |  |
| `--threshold` | float | 0.7 |  |
| `--format` | str | 'json' |  |
| `--use-api` | str | Required | Use UMLS/MeSH APIs |
| `--api-key` | str | Required |  |

## Output Requirements

Every final response should make these items explicit when they are relevant:

- Objective or requested deliverable
- Inputs used and assumptions introduced
- Workflow or decision path
- Core result, recommendation, or artifact
- Constraints, risks, caveats, or validation needs
- Unresolved items and next-step checks

## Error Handling

- If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
- If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
- If `scripts/main.py` fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
- Do not fabricate files, citations, data, search results, or execution outcomes.

## Input Validation

This skill accepts requests that match the documented purpose of `bio-ontology-mapper` and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

> `bio-ontology-mapper` only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

## Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.

# Research Authorship and Contributor Credit Generator

## When to Use

- Use this skill when the task needs Use when determining author order on research manuscripts, assigning CRediT contributor roles for transparency, documenting individual contributions to collaborative projects, or resolving authorship disputes in multi-institutional research. Generates fair and transparent authorship assignments following ICMJE guidelines and CRediT taxonomy. Helps research teams document contributions, resolve disputes, and ensure equitable credit distribution in academic publications.
- Use this skill for academic writing tasks that require explicit assumptions, bounded scope, and a reproducible output format.
- Use this skill when you need a documented fallback path for missing inputs, execution errors, or partial evidence.

## Key Features

- Scope-focused workflow aligned to: Use when determining author order on research manuscripts, assigning CRediT contributor roles for transparency, documenting individual contributions to collaborative projects, or resolving authorship disputes in multi-institutional research. Generates fair and transparent authorship assignments following ICMJE guidelines and CRediT taxonomy. Helps research teams document contributions, resolve disputes, and ensure equitable credit distribution in academic publications.
- Packaged executable path(s): `scripts/main.py`.
- Reference material available in `references/` for task-specific guidance.
- Structured execution path designed to keep outputs consistent and reviewable.

## Dependencies

- `Python`: `3.10+`. Repository baseline for current packaged skills.
- `dataclasses`: `unspecified`. Declared in `requirements.txt`.

## Example Usage

```bash
cd "20260318/scientific-skills/Academic Writing/authorship-credit-gen"
python -m py_compile scripts/main.py
python scripts/main.py --help
```

Example run plan:
1. Confirm the user input, output path, and any required config values.
2. Edit the in-file `CONFIG` block or documented parameters if the script uses fixed settings.
3. Run `python scripts/main.py` with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

## Implementation Details

See `## Workflow` above for related details.

- Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
- Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
- Primary implementation surface: `scripts/main.py`.
- Reference guidance: `references/` contains supporting rules, prompts, or checklists.
- Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
- Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

## Quick Check

Use this command to verify that the packaged script entry point can be parsed before deeper execution.

```bash
python -m py_compile scripts/main.py
```

## Audit-Ready Commands

Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths.

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
```

## Workflow

1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work.
2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions.
3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available.
4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items.
5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion.

## When to Use This Skill

- determining author order on research manuscripts
- assigning CRediT contributor roles for transparency
- documenting individual contributions to collaborative projects
- resolving authorship disputes in multi-institutional research
- preparing contributor statements for journal submissions
- evaluating contribution equity in research teams

# Generate fair authorship order
authorship = generator.determine_order(
    contributions=contributions,
    criteria=["intellectual_input", "execution", "writing", "supervision"],
    weights={"intellectual_input": 0.4, "execution": 0.3, "writing": 0.2, "supervision": 0.1}
)

print(f"First author: {authorship.first_author}")
print(f"Corresponding: {authorship.corresponding_author}")
print(f"Author order: {authorship.ordered_list}")

# Generate CRediT statement
credit_statement = generator.generate_credit_statement(
    contributions=contributions,
    format="journal_submission"
)

# Check for disputes
dispute_check = generator.check_equity_issues(authorship)
if dispute_check.has_issues:
    print(f"Recommendations: {dispute_check.recommendations}")
```

## Core Capabilities

### 1. Generate Fair Authorship Orders

Analyze contributions using weighted criteria to determine equitable author ranking.

```python

# Define weighted contribution criteria
weights = {
    "conceptualization": 0.25,
    "methodology_design": 0.20,
    "data_collection": 0.15,
    "analysis": 0.15,
    "manuscript_writing": 0.15,
    "supervision": 0.10
}

# Calculate contribution scores
scores = tool.calculate_contribution_scores(
    contributions=team_contributions,
    weights=weights
)

# Generate ordered author list
authorship_order = tool.generate_author_order(scores)
print(f"Recommended order: {authorship_order}")
```

### 2. Assign CRediT Roles

Map contributions to official CRediT (Contributor Roles Taxonomy) categories.

```python

# Map contributions to CRediT roles
credit_roles = tool.assign_credit_roles(
    contributions=contributions,
    version="CRediT_2021"
)

# Generate CRediT statement for journal
statement = tool.generate_credit_statement(
    roles=credit_roles,
    format="JATS_XML"
)

# Validate role assignments
validation = tool.validate_credit_roles(credit_roles)
if validation.is_valid:
    print("CRediT roles properly assigned")
```

### 3. Detect Contribution Inequities

Identify potential authorship disputes before submission.

```python

# Analyze contribution distribution
equity_analysis = tool.analyze_equity(
    contributions=contributions,
    thresholds={"min_substantial": 0.15}
)

# Flag potential issues
if equity_analysis.has_inequities:
    for issue in equity_analysis.issues:
        print(f"Warning: {issue.description}")
        print(f"Recommendation: {issue.recommendation}")

# Generate equity report
report = tool.generate_equity_report(equity_analysis)
```

### 4. Generate Journal-Ready Statements

Create formatted contributor statements for various journal requirements.

```python

# Generate for Nature-style statement
nature_statement = tool.generate_contributor_statement(
    style="Nature",
    include_competing_interests=True
)

# Generate for Science-style statement  
science_statement = tool.generate_contributor_statement(
    style="Science",
    include_author_contributions=True
)

# Export in multiple formats
tool.export_statement(
    statement=nature_statement,
    formats=["docx", "pdf", "txt"]
)
```

## Command Line Usage

```text
python scripts/main.py --contributions contributions.json --guidelines ICMJE --output authorship_order.json
```

## Best Practices

- Discuss authorship expectations at project inception
- Document contributions continuously throughout project
- Review and agree on author order before submission
- Include non-author contributors in acknowledgments

## Quality Checklist

Before using this skill, ensure you have:
- [ ] Clear understanding of your objectives
- [ ] Necessary input data prepared and validated
- [ ] Output requirements defined
- [ ] Reviewed relevant documentation

After using this skill, verify:
- [ ] Results meet your quality standards
- [ ] Outputs are properly formatted
- [ ] Any errors or warnings have been addressed
- [ ] Results are documented appropriately

## References

- `references/guide.md` - Comprehensive user guide
- `references/examples/` - Working code examples
- `references/api-docs/` - Complete API documentation

---

**Skill ID**: 766 | **Version**: 1.0 | **License**: MIT

## Output Requirements

Every final response should make these items explicit when they are relevant:

- Objective or requested deliverable
- Inputs used and assumptions introduced
- Workflow or decision path
- Core result, recommendation, or artifact
- Constraints, risks, caveats, or validation needs
- Unresolved items and next-step checks

## Error Handling

- If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
- If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
- If `scripts/main.py` fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
- Do not fabricate files, citations, data, search results, or execution outcomes.

## Input Validation

This skill accepts requests that match the documented purpose of `authorship-credit-gen` and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

> `authorship-credit-gen` only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

## References

- [references/audit-reference.md](references/audit-reference.md) - Supported scope, audit commands, and fallback boundaries

## Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.

# Audit Reference

## Scope

- Skill: `authorship-credit-gen`
- Core purpose: Use when determining author order on research manuscripts, assigning CRediT contributor roles for transparency, documenting individual contributions to collaborative projects, or resolving authorship disputes in multi-institutional research. Generates fair and transparent authorship assignments following ICMJE guidelines and CRediT taxonomy. Helps research teams document contributions, resolve disputes, and ensure equitable credit distribution in academic publications.
- Use only within the documented workflow and category boundary defined in `SKILL.md`

## Supported Audit Paths

- `python -m py_compile scripts/main.py`
- `python scripts/main.py --help`

## Fallback Boundary

If required inputs are incomplete, the skill should still return:

- the missing required inputs
- the steps that can still be completed safely
- assumptions that need confirmation before execution
- the next checks before accepting the final deliverable

- **Downstream**: `cover-letter-drafter` (application materials), `networking-email-drafter` (alumni outreach)

## Core Capabilities

### 1. Alumni Database Management

Collect and organize career outcome data:

```python
from scripts.tracker import AlumniTracker

tracker = AlumniTracker()

# Add single alumni record
alumni = {
    "name": "Dr. Sarah Chen",
    "graduation_year": 2023,
    "degree": "PhD",
    "current_status": "industry",
    "organization": "Genentech",
    "position": "Senior Scientist",
    "location": "San Francisco, CA",
    "field": "Immuno-oncology",
    "salary_range": "$140k-$160k",
    "linkedin": "linkedin.com/in/sarahchen"
}

tracker.add_alumni(alumni)

# Batch import from CSV
tracker.import_csv("alumni_2020_2024.csv")
```

**Data Fields:**
| Field | Required | Description |
|-------|----------|-------------|
| name | Yes | Full name |
| graduation_year | Yes | Year completed degree |
| degree | Yes | PhD/Master/Bachelor/Postdoc |
| current_status | Yes | industry/academia/startup/gov/other |
| organization | Yes | Company/University/Institution |
| position | Yes | Job title or rank |
| location | No | City/Country |
| field | No | Research/industry area |
| salary_range | No | Optional compensation |
| linkedin | No | Profile for tracking updates |

### 2. Career Outcome Analysis

Generate comprehensive statistics and visualizations:

```python
# Analyze by degree level
analysis = tracker.analyze(
    degree_filter=["PhD", "Master"],
    year_range=(2020, 2024),
    metrics=["sector_distribution", "geographic_spread", "salary_trends"]
)

# Generate report
report = analysis.generate_report(format="pdf")
report.save("lab_career_outcomes_2024.pdf")
```

**Analysis Dimensions:**
- **Sector Distribution**: Industry vs. Academia vs. Government vs. Other
- **By Degree Level**: PhD, Master, Bachelor outcomes
- **Geographic Trends**: Regional employment patterns
- **Temporal Trends**: Year-over-year changes
- **Salary Benchmarks**: By degree, sector, and years post-graduation
- **Top Employers**: Most common companies and institutions

### 3. Career Pathway Mapping

Visualize common career trajectories:

```python
# Map career pathways
pathways = tracker.map_pathways(
    start_degree="PhD",
    target_years=[0, 2, 5, 10],
    min_samples=5
)

# Visualize as Sankey diagram
pathways.visualize(output="career_flows.html")
```

**Visualization Types:**
- **Sankey Diagrams**: Flow from degree → first job → current position
- **Timeline Views**: Individual career progression over time
- **Network Graphs**: Alumni connections and referrals
- **Heatmaps**: Skills vs. job requirements

### 4. Personalized Career Recommendations

Generate tailored advice for current trainees:

```python
# Get recommendations for a student
recommendations = tracker.get_recommendations(
    current_degree="PhD",
    research_area="Cancer Biology",
    interests=["industry", "translational research"],
    years_to_graduation=2
)

print(recommendations.top_pathways)
print(recommendations.skill_gaps)
print(recommendations.network_contacts)
```

**Recommendation Categories:**
- **Top Pathways**: Most common routes for similar backgrounds
- **Skill Gaps**: Missing competencies for target roles
- **Network Contacts**: Alumni in relevant positions
- **Timeline**: Expected job search duration by sector
- **Preparation Steps**: Actionable next steps

## Common Patterns

### Pattern 1: New Student Onboarding

**Scenario**: First-year PhD student exploring career options.

```bash
# Generate career landscape overview
python scripts/main.py \
  --analyze \
  --degree PhD \
  --last-5-years \
  --output new_student_briefing.pdf

# Show specific pathways for their research area
python scripts/main.py \
  --pathways \
  --field "Cancer Immunotherapy" \
  --visualize \
  --output immunotherapy_careers.html
```

**Output Includes:**
- "65% of PhD alumni from our lab go to industry, 25% to academia"
- "Top companies hiring: Genentech (8 alumni), Pfizer (5), Stanford (4)"
- "Average time to first job: 3.2 months for industry, 8.1 months for academia"
- Recommended alumni to connect with

### Pattern 2: Training Grant Application

**Scenario**: Lab needs career outcome data for NIH T32 renewal.

```python
# Generate NIH-compliant report
report = tracker.generate_training_report(
    grant_type="T32",
    years=(2019, 2024),
    include_placements=True,
    include_salaries=False,  # Optional for privacy
    format="docx"
)

# Key metrics for NIH
print(f"Placement rate: {report.placement_rate}%")  # >95% target
print(f"Research-related jobs: {report.research_related}%")  # >80% target
print(f"Underrepresented minorities: {report.urm_percentage}%")
```

**NIH Requirements Met:**
- ✓ Placement rates within 6 months of graduation
- ✓ Research-related vs. non-research positions
- ✓ Diversity and underrepresented minority outcomes
- ✓ Career progression over time

### Pattern 3: Industry Partnership Development

**Scenario**: Lab wants to identify companies for collaboration.

```bash
# Analyze industry destinations
python scripts/main.py \
  --analyze \
  --filter-status industry \
  --group-by company \
  --output industry_partners.pdf

# Identify senior alumni for advisory roles
python scripts/main.py \
  --filter "position:Director,VP,Senior Manager" \
  --export contacts_for_outreach.csv
```

**Insights Generated:**
- Companies with most alumni (potential champions)
- Senior alumni in decision-making roles
- Geographic clusters for regional events
- Skills overlap with company needs

### Pattern 4: Individual Career Counseling

**Scenario**: Third-year PhD student deciding between industry and academia.

```python
# Personalized analysis for the student
student_profile = {
    "degree": "PhD",
    "research_area": "CRISPR gene editing",
    "publications": 3,
    "interests": ["startup", "gene therapy"]
}

comparison = tracker.compare_pathways(
    profile=student_profile,
    options=["industry", "startup", "academia"],
    metrics=["salary", "job_security", "work_life_balance", "availability"]
)

comparison.generate_personalized_report("career_comparison.pdf")
```

**Comparison Includes:**
- Salary ranges by path (year 1, 5, 10)
- Job market availability (positions per year)
- Alumni satisfaction ratings
- Required additional skills/training
- Network introductions

## Complete Workflow Example

**From data collection to actionable insights:**

```bash
# Step 1: Import existing alumni data
python scripts/main.py \
  --import alumni_survey_2024.csv \
  --validate \
  --output clean_alumni.json

# Step 2: Update LinkedIn profiles
python scripts/main.py \
  --update-linkedin \
  --input clean_alumni.json \
  --output updated_alumni.json

# Step 3: Generate comprehensive report
python scripts/main.py \
  --full-analysis \
  --years 2019-2024 \
  --output-dir career_report_2024/

# Step 4: Create visualization dashboard
python scripts/main.py \
  --dashboard \
  --serve \
  --port 8080
```

**Python API:**

```python
from scripts.tracker import AlumniTracker
from scripts.analyzer import CareerAnalyzer
from scripts.recommender import CareerRecommender

# Initialize
tracker = AlumniTracker(data_path="alumni_db.json")
analyzer = CareerAnalyzer()
recommender = CareerRecommender()

# Load and clean data
tracker.import_csv("alumni_2024.csv")
tracker.clean_data()

# Generate analysis
analysis = analyzer.analyze(tracker.data)
print(f"Industry rate: {analysis.industry_ratio:.1%}")
print(f"Median PhD salary (Year 1): ,")

# Generate recommendations for a student
recs = recommender.recommend(
    current_student={
        "year": 3,
        "degree": "PhD",
        "field": "Neuroscience"
    },
    alumni_data=tracker.data
)

print("Top 3 career paths:")
for i, path in enumerate(recs.top_paths[:3], 1):
    print(f"{i}. {path.name} ({path.probability:.0%} match)")
```

## Quality Checklist

**Data Collection:**
- [ ] Alumni consent obtained for tracking
- [ ] Data anonymized for reports (aggregated statistics only)
- [ ] GDPR/privacy compliance verified
- [ ] Regular update schedule established (annual recommended)

**Analysis Accuracy:**
- [ ] Minimum 30 alumni for statistically meaningful patterns
- [ ] Data validated for completeness (>80% response rate)
- [ ] Outliers identified and verified
- [ ] Salary data optional (respect privacy)

**Reporting:**
- [ ] **CRITICAL**: Individual privacy protected (no identifiable info in reports)
- [ ] Trends contextualized (mention sample size limitations)
- [ ] Multiple timeframes analyzed (short-term vs. long-term outcomes)
- [ ] Comparative benchmarks included (department/field averages)

**Before Sharing:**
- [ ] Alumni review opportunity provided
- [ ] **CRITICAL**: No individual salary data shared
- [ ] Aggregate statistics only in public reports
- [ ] Opt-out preferences respected

## Common Pitfalls

**Data Quality Issues:**
- ❌ **Low response rate** → Biased sample (only successful alumni respond)
  - ✅ Aim for >70% response rate; follow up multiple times
  
- ❌ **Outdated information** → Tracking 5-year-old data
  - ✅ Annual updates; LinkedIn monitoring for changes

- ❌ **Small sample size** → Drawing conclusions from n<10
  - ✅ Report confidence intervals; avoid over-interpretation

**Privacy Issues:**
- ❌ **Sharing individual salaries** → Violates privacy expectations
  - ✅ Report salary ranges or medians only; aggregate by groups

- ❌ **Identifiable case studies without consent** → Privacy breach
  - ✅ Always get written permission before highlighting individuals

**Interpretation Issues:**
- ❌ **Comparing to top-tier labs only** → Unrealistic expectations
  - ✅ Compare to similar-tier institutions; contextualize differences

- ❌ **Attributing success to lab alone** → Ignores individual factors
  - ✅ Acknowledge external factors; avoid causal claims

**Communication Issues:**
- ❌ **Discouraging academia based on low placement rates** → Biased counseling
  - ✅ Present all options neutrally; match to individual goals

- ❌ **Over-promising industry salaries** → Unrealistic expectations
  - ✅ Include salary ranges; mention geographic variations

- **Privacy Constraints**: Cannot collect detailed data without consent
- **Sample Size**: Small labs may have insufficient data for statistical significance
- **Temporal Changes**: Job market shifts may make historical data less relevant
- **Attribution Difficulty**: Cannot isolate lab impact from individual factors
- **International Tracking**: Difficulty tracking alumni who leave country

# ADME Property Predictor

## When to Use

- Use this skill when the task needs 1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work. 2. Validate that the request matches the documented scope and stop early if the task would require unsupported as.
- Use this skill for data analysis tasks that require explicit assumptions, bounded scope, and a reproducible output format.
- Use this skill when you need a documented fallback path for missing inputs, execution errors, or partial evidence.

## Key Features

- Scope-focused workflow aligned to: Analyze data with `adme-property-predictor` using a reproducible workflow, explicit validation, and structured outputs for review-ready interpretation.
- Packaged executable path(s): `scripts/main.py`.
- Reference material available in `references/` for task-specific guidance.
- Structured execution path designed to keep outputs consistent and reviewable.

## Dependencies

- `Python`: `3.10+`. Repository baseline for current packaged skills.
- `dataclasses`: `unspecified`. Declared in `requirements.txt`.
- `rdkit`: `unspecified`. Declared in `requirements.txt`.

## Example Usage

```bash
cd "20260318/scientific-skills/Data Analytics/adme-property-predictor"
python -m py_compile scripts/main.py
python scripts/main.py --help
```

Example run plan:
1. Confirm the user input, output path, and any required config values.
2. Edit the in-file `CONFIG` block or documented parameters if the script uses fixed settings.
3. Run `python scripts/main.py` with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

## Implementation Details

See `## Workflow` above for related details.

- Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
- Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
- Primary implementation surface: `scripts/main.py`.
- Reference guidance: `references/` contains supporting rules, prompts, or checklists.
- Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
- Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

## Quick Check

Use this command to verify that the packaged script entry point can be parsed before deeper execution.

```bash
python -m py_compile scripts/main.py
```

## Audit-Ready Commands

Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths.

```bash
python -m py_compile scripts/main.py

# Example invocation: python scripts/main.py --help

# Example invocation: python scripts/main.py --input "Audit validation sample with explicit symptoms, history, assessment, and next-step plan." --format json
```

## Workflow

1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work.
2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions.
3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available.
4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items.
5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion.

## Overview

Comprehensive pharmacokinetic prediction tool that assesses drug-likeness and ADME properties of small molecules using validated cheminformatics models, molecular descriptors, and structure-property relationships.

**Key Capabilities:**
- **Multi-Property Prediction**: Absorption, Distribution, Metabolism, Excretion
- **Drug-Likeness Scoring**: Lipinski's Rule of 5, Veber rules, QED score
- **Batch Processing**: Analyze compound libraries efficiently
- **Structure-Based Insights**: Identify liability hotspots and optimization opportunities
- **Comparative Analysis**: Rank candidates by predicted PK profile

## Integration with Other Skills

**Upstream Skills:**
- `chemical-structure-converter`: Convert between SMILES, InChI, MOL formats
- `lipinski-rule-filter`: Initial rule-based drug-likeness screening
- `chemical-structure-converter`: Generate 3D conformers for structure-based predictions
- `smiles-de-salter`: Remove salt counterions before analysis

**Downstream Skills:**
- `drug-candidate-evaluator`: Multi-parameter optimization including ADME
- `toxicity-structure-alert`: Assess safety alongside ADME
- `target-novelty-scorer`: Evaluate target uniqueness for selected candidates
- `biotech-pitch-deck-narrative`: Create investor materials with PK data

**Complete Workflow:**
```
Chemical Structure Converter (prepare structures) → 
  Lipinski Rule Filter (initial filtering) → 
    ADME Property Predictor (this skill, detailed PK) → 
      Drug Candidate Evaluator (integrated scoring) → 
        Toxicity Structure Alert (safety check)
```

predictor = ADMEPredictor()

# Predict absorption properties
absorption = predictor.predict_absorption(
    smiles="CC(=O)Oc1ccccc1C(=O)O",  # Aspirin
    properties=["all"]  # or specific: ["hia", "caco2", "solubility"]
)

print(absorption.summary())
```

**Predicted Properties:**
| Property | Model | Units | Interpretation |
|----------|-------|-------|----------------|
| **HIA** | ML + physicochemical | % | Human intestinal absorption; >80% good |
| **Caco-2** | QSPR | 10⁻⁶ cm/s | Permeability; >70 high, <25 low |
| **Solubility** | QSPR | mg/mL | Aqueous solubility; >0.1 mg/mL acceptable |
| **LogS** | QSPR | unitless | Intrinsic solubility; >-4 acceptable |
| **Lipinski Pass** | Rule-based | boolean | Passes all 5 rules |
| **Veber Pass** | Rule-based | boolean | PSA <140, rotatable bonds <10 |

**Best Practices:**
- ✅ Consider HIA and solubility together (high HIA but low solubility = dissolution-limited)
- ✅ Caco-2 good for oral absorption prediction; poor for BBB penetration
- ✅ Use both rule-based (Lipinski) and ML-based predictions for consensus
- ✅ Check solubility at physiological pH (not just intrinsic)

**Common Issues and Solutions:**

**Issue: Lipinski pass but poor solubility**
- Symptom: "Passes Rule of 5 but LogS = -5"
- Solution: Lipinski checks MW and LogP, not solubility directly; use explicit solubility prediction

**Issue: Caco-2 predicts high absorption but HIA low**
- Symptom: "Caco-2 = 85 (high) but HIA = 60%"
- Solution: Models have different training sets; Caco-2 is in vitro, HIA in vivo; HIA generally more reliable

### 2. Distribution (D) Prediction

Predict tissue distribution, protein binding, and brain penetration:

```python

# Predict distribution properties
distribution = predictor.predict_distribution(
    smiles="CC(=O)Oc1ccccc1C(=O)O",
    properties=["vd", "ppb", "bbb"]
)

# Access specific predictions
vd = distribution.volume_of_distribution
bbb = distribution.blood_brain_barrier
ppb = distribution.plasma_protein_binding
```

**Predicted Properties:**
| Property | Model | Units | Interpretation |
|----------|-------|-------|----------------|
| **Vd** | QSPR | L/kg | Volume of distribution; 0.1-10 typical |
| **PPB** | ML | % | Plasma protein binding; >90% high, <50% low |
| **BBB** | LogBB | unitless | Brain penetration; >0.3 penetrant |
| **fu** | Calculated | fraction | Free (unbound) fraction; 1 - PPB/100 |

**Best Practices:**
- ✅ High PPB (>90%) may require higher doses but longer half-life
- ✅ Low Vd (<0.3) = mainly in plasma; high Vd (>3) = extensive tissue distribution
- ✅ BBB penetration critical for CNS drugs; avoid for peripherally-acting drugs
- ✅ fu (free fraction) drives pharmacological activity, not total concentration

**Common Issues and Solutions:**

**Issue: BBB predictions unreliable for certain chemotypes**
- Symptom: "BBB model gives conflicting predictions for peptides"
- Solution: Models trained on small molecules; use specialized BBB predictors for peptides, macrocycles

**Issue: PPB overestimated for acidic drugs**
- Symptom: "PPB predicted 95% but experimental is 70%"
- Solution: Some models biased toward neutral/basic compounds; check model training set overlap

### 3. Metabolism (M) Prediction

Predict metabolic stability, CYP interactions, and liability sites:

```python

# Predict metabolism properties
metabolism = predictor.predict_metabolism(
    smiles="CC(=O)Oc1ccccc1C(=O)O",
    include_site_prediction=True
)

# Check CYP interactions
cyp_profile = metabolism.cyp_profile
stability = metabolism.metabolic_stability
```

**Predicted Properties:**
| Property | Model | Output | Interpretation |
|----------|-------|--------|----------------|
| **CYP Inhibition** | ML | IC50 or class | Potential DDI; <1 μM high risk |
| **CYP Substrate** | Classification | Boolean/Probability | Metabolized by specific CYP |
| **Stability** | ML | T1/2 or class | Microsomal/ hepatocyte stability |
| **Liability Sites** | Reactivity models | Atom indices | Soft spots for metabolism |
| **MAO Substrate** | Classification | Boolean | Monoamine oxidase substrate |

**Best Practices:**
- ✅ Screen for CYP3A4 inhibition early (most common DDI)
- ✅ Check if compound is CYP substrate (for polymorphism concerns)
- ✅ Identify metabolic hotspots for structural blocking
- ✅ Consider species differences (human vs rodent metabolism)

**Common Issues and Solutions:**

**Issue: False negatives for time-dependent inhibition (TDI)**
- Symptom: "No CYP inhibition predicted but TDI observed experimentally"
- Solution: Standard models predict reversible inhibition; use specialized TDI predictors

**Issue: Metabolic site prediction shows multiple hotspots**
- Symptom: "5 different atoms flagged as metabolic liabilities"
- Solution: Prioritize by reactivity score; consider blocking highest-risk site first

### 4. Excretion (E) Prediction

Predict clearance routes and elimination kinetics:

```python

# Predict excretion properties
excretion = predictor.predict_excretion(
    smiles="CC(=O)Oc1ccccc1C(=O)O",
    properties=["clearance", "half_life", "route"]
)

# Access predictions
clearance = excretion.clearance_ml_min_kg
t12 = excretion.half_life_hours
route = excretion.primary_route
```

**Predicted Properties:**
| Property | Model | Units | Interpretation |
|----------|-------|-------|----------------|
| **CL** | QSPR | mL/min/kg | Clearance; <5 low, 5-15 moderate, >15 high |
| **T1/2** | QSPR | hours | Half-life; 2-8h typical for oral drugs |
| **Route** | Classification | renal/biliary/mixed | Primary excretion pathway |
| **LogD** | QSPR | unitless | Distribution coefficient; affects clearance |

**Best Practices:**
- ✅ Half-life determines dosing frequency (T1/2 × 5 = time to steady state)
- ✅ Renal clearance predictable for polar compounds; hepatic less predictable
- ✅ High clearance (>15) may require high doses or prodrug approach
- ✅ Very long T1/2 (>24h) good for adherence but risk accumulation

**Common Issues and Solutions:**

**Issue: Clearance predictions highly variable**
- Symptom: "Same compound, different models give CL = 5 vs 20 mL/min/kg"
- Solution: Allometry-based methods unreliable for novel scaffolds; use average of multiple models

**Issue: Route prediction contradicts structure**
- Symptom: "Highly polar compound predicted biliary, expected renal"
- Solution: Check LogP/LogD; polar compounds (<0) usually renal; neutral/lipophilic (>1) usually hepatic

### 5. Integrated Drug-Likeness Scoring

Overall assessment combining all ADME properties:

```python

# Generate comprehensive drug-likeness score
druglikeness = predictor.calculate_druglikeness(
    smiles="CC(=O)Oc1ccccc1C(=O)O",
    methods=["qed", "muegge", "golden_triangle"]
)

# Multi-parameter optimization
mpo_score = predictor.mpo_score(
    smiles="CC(=O)Oc1ccccc1C(=O)O",
    target_profile={"hia": >80, "bbb": <0.3, "t12": "2-8h"}
)
```

**Scoring Methods:**
| Method | Description | Range | Good Score |
|--------|-------------|-------|------------|
| **QED** | Quantitative Estimation of Drug-likeness | 0-1 | >0.6 |
| **Muegge** | Bioavailability score | 0-6 | >4 |
| **MPO** | Multi-Parameter Optimization | 0-10 | >6 |

**Best Practices:**
- ✅ Use QED as quick overall metric; MPO for property-weighted scoring
- ✅ Don't rely solely on drug-likeness; efficacy and safety equally important
- ✅ Compare to marketed drugs in same class for context
- ✅ Track drug-likeness trends during optimization (should improve)

**Common Issues and Solutions:**

**Issue: Drug-likeness score conflicts with project needs**
- Symptom: "CNS drug has low QED (0.5) because high LogP needed for BBB"
- Solution: Drug-likeness rules biased toward oral drugs; use category-specific models (CNS, oncology, etc.)

### 6. Batch Processing and Library Screening

Analyze compound libraries efficiently:

```python

# Batch process library
results = predictor.batch_predict(
    input_file="library.smi",  # SMILES file
    properties=["all"],
    output_format="csv",
    n_workers=4  # Parallel processing
)

# Filter by criteria
filtered = results.filter(
    lipinski_pass=True,
    hia__gt=80,
    t12__between=(2, 8)
)

# Rank by multi-parameter score
ranked = results.rank(by="mpo_score", ascending=False)
```

**Best Practices:**
- ✅ Process in batches of 1000-10000 for memory efficiency
- ✅ Save intermediate results (crash recovery)
- ✅ Apply filters sequentially (Lipinski first, then detailed ADME)
- ✅ Check property distributions to identify outliers

**Common Issues and Solutions:**

**Issue: Batch processing runs out of memory**
- Symptom: "Killed: Out of memory" with 50K compounds
- Solution: Process in chunks; use generators instead of loading all into RAM

**Issue: Some compounds fail prediction**
- Symptom: "30% of library returns NaN"
- Solution: Check for invalid SMILES, unusual atoms, or molecules outside training set domain

## Complete Workflow Example

**From SMILES to prioritized candidates:**

```text

# Step 1: Predict ADME for single compound

# Example invocation: python scripts/main.py \
  --smiles "CC(=O)Oc1ccccc1C(=O)O" \
  --properties all \
  --output aspirin_adme.json

# Step 2: Batch process compound library

# Example invocation: python scripts/main.py \
  --input library.smi \
  --properties absorption,distribution \
  --format csv \
  --output library_adme.csv

# Step 3: Filter and rank

# Example invocation: python scripts/main.py \
  --input library_adme.csv \
  --filter "lipinski_pass=True,hia>80" \
  --rank-by qed \
  --top-n 100 \
  --output top_candidates.csv

```

**Python API Usage:**

```python
from scripts.adme_predictor import ADMEPredictor
from scripts.batch_processor import BatchProcessor

# Initialize
predictor = ADMEPredictor()
batch = BatchProcessor()

# Single compound analysis
aspirin = predictor.predict_all("CC(=O)Oc1ccccc1C(=O)O")
print(f"HIA: {aspirin.absorption.hia}%")
print(f"Half-life: {aspirin.excretion.t12} hours")

# Batch screening
results = batch.process(
    input_file="library.smi",
    predictor=predictor,
    properties=["absorption", "distribution"],
    n_workers=4
)

# Filter good candidates
good_candidates = results[
    (results.lipinski_pass == True) &
    (results.hia > 80) &
    (results.bbb < 0.3) &
    (results.t12.between(2, 8))
]
```

**Expected Output Files:**
```
output/
├── aspirin_adme.json           # Single compound detailed results
├── library_adme.csv            # Batch screening results
├── top_candidates.csv          # Filtered and ranked candidates
```

## Quality Checklist

**Pre-Prediction Checks:**
- [ ] SMILES string is valid and canonical
- [ ] Salt forms removed (if analyzing parent compound)
- [ ] Tautomeric state appropriate for physiological pH
- [ ] Stereochemistry specified (if relevant for activity)

**During Prediction:**
- [ ] Compound within model applicability domain (check similarity to training set)
- [ ] No unusual atoms or functional groups (models trained on typical drug-like space)
- [ ] MW in range 100-800 Da (outside range predictions less reliable)
- [ ] Predictions complete (no missing values for critical properties)

**Post-Prediction Verification:**
- [ ] Drug-likeness scores in reasonable range (sanity check)
- [ ] Individual properties internally consistent (e.g., high LogP predicts low solubility)
- [ ] **CRITICAL**: Comparison to experimental data if available (validate model for chemotype)
- [ ] Rankings align with medicinal chemistry intuition

**Before Making Decisions:**
- [ ] **CRITICAL**: Predictions are NOT experimental data; use for prioritization only
- [ ] Multiple orthogonal models give consistent results
- [ ] Structural alerts checked (toxicity, reactivity)
- [ ] Top candidates selected for experimental validation
- [ ] Documentation of model versions and confidence intervals

**For Regulatory Submissions:**
- [ ] Model validation documented (training set, test set performance)
- [ ] Applicability domain clearly defined
- [ ] Prediction uncertainty quantified
- [ ] Experimental confirmation for key predictions

## Common Pitfalls

**Over-Reliance Issues:**
- ❌ **Treating predictions as experimental facts** → Poor decision making
  - ✅ Use predictions for prioritization; experimental validation required for lead optimization

- ❌ **Single model dependency** → Miss model-specific biases
  - ✅ Compare multiple models; consensus predictions more reliable

- ❌ **Ignoring prediction confidence** → False sense of certainty
  - ✅ Check confidence intervals; low confidence predictions need higher scrutiny

**Input Issues:**
- ❌ **Invalid or non-canonical SMILES** → Wrong compound analyzed
  - ✅ Validate SMILES before prediction; use canonical forms

- ❌ **Analyzing salt forms** → Properties skewed by counterion
  - ✅ Remove salts using `smiles-de-salter`; analyze free base/acid

- ❌ **Ignoring stereochemistry** → Inaccurate predictions for chiral drugs
  - ✅ Specify stereochemistry explicitly; use 3D descriptors if available

**Interpretation Issues:**
- ❌ **Focusing on single property** → Miss overall profile
  - ✅ Consider all ADME properties; use integrated scores like QED or MPO

- ❌ **Rigid cutoff application** → Discard good candidates
  - ✅ Use cutoffs as guidelines; consider project-specific needs

- ❌ **Ignoring property correlations** → Unrealistic optimization
  - ✅ Recognize trade-offs (e.g., increasing LogP improves BBB but reduces solubility)

**Domain Issues:**
- ❌ **Applying to biologics** → Completely inappropriate
  - ✅ These models for small molecules only; use specialized tools for biologics

- ❌ **Extrapolating beyond training set** → Unreliable predictions
  - ✅ Check applicability domain; novel scaffolds need experimental validation

**Workflow Issues:**
- ❌ **No experimental validation** → Continue with false leads
  - ✅ Always validate top predictions experimentally

- ❌ **Not documenting model versions** → Irreproducible results
  - ✅ Record software version, model versions, prediction dates

## Troubleshooting

**Problem: All predictions show "out of domain" warning**
- Symptoms: "Compound outside training set" for entire library
- Causes: Library contains unusual chemotypes (peptidomimetics, macrocycles, etc.)
- Solutions:
  - Use specialized models for non-traditional chemotypes
  - Check if input format correct (SMILES vs InChI)
  - Verify no strange atoms (metals, silicon, etc.)

**Problem: Extreme predictions (negative solubility, >100% absorption)**
- Symptoms: "LogS = -15" or "HIA = 150%"
- Causes: Model extrapolation errors; invalid input structures
- Solutions:
  - Check input structure validity
  - Cap extreme values at physiologically plausible limits
  - Flag for manual review if outside typical ranges

**Problem: Batch processing extremely slow**
- Symptoms: "100 compounds taking 30 minutes"
- Causes: Single-threaded execution; complex models
- Solutions:
  - Enable parallel processing (--n-workers 4)
  - Use faster models for initial screening (QSAR vs ML)
  - Pre-filter with rule-based methods (Lipinski) before detailed ADME

**Problem: Inconsistent predictions across runs**
- Symptoms: "Same compound, different predictions on re-run"
- Causes: Random seed issues; stochastic models
- Solutions:
  - Set random seeds for reproducibility
  - Use deterministic models when consistency critical
  - Average multiple predictions if stochastic models necessary

**Problem: Properties contradict each other**
- Symptoms: "High LogP (4.5) but predicted very soluble"
- Causes: Model inconsistencies; prediction errors
- Solutions:
  - Check input structure (tautomeric form matters for both)
  - Lipophilic compounds (LogP > 3) typically have poor solubility
  - Use thermodynamic cycle checks if available

**Problem: Cannot process certain file formats**
- Symptoms: "Error: Unsupported format" for SDF or MOL files
- Causes: Format limitations; parser issues
- Solutions:
  - Convert to SMILES using `chemical-structure-converter`
  - Check file encoding (UTF-8 vs Latin-1)
  - Verify structure validity with external tools

## Performance and Resources

**Prediction Speed:**
| Task | Time | Hardware |
|------|------|----------|
| Single compound | 0.5-2 sec | CPU |
| 100 compounds | 30-60 sec | CPU |
| 1000 compounds | 5-10 min | CPU |
| 1000 compounds | 2-3 min | 4-core parallel |
| 10,000 compounds | 30-60 min | 4-core parallel |

**System Requirements:**
- **RAM**: 4 GB minimum; 8 GB for large libraries (>10K compounds)
- **Storage**: 100 MB for models and dependencies
- **CPU**: Multi-core recommended for batch processing
- **No GPU required**: All models CPU-based

**Optimization Tips:**
- Process libraries in batches of 5000-10000
- Use rule-based filters (Lipinski) before expensive ML predictions
- Cache results to avoid re-prediction
- Parallel processing scales nearly linearly up to 8 cores

## Limitations

- **Small Molecules Only**: Models trained on drugs with MW 100-800 Da; unreliable for larger compounds
- **pH 7.4 Assumption**: Most models predict properties at physiological pH
- **Human-Specific**: Predictions for human PK; animal models may differ
- **Healthy Subject Assumption**: Does not account for disease states, drug interactions
- **Single Compound**: Does not predict formulation effects, salt form impact
- **Static Models**: Do not account for induction, inhibition, or time-dependent changes
- **Training Set Bias**: Underperforms for novel scaffolds not in training data
- **Qualitative Only**: For Go/No-Go decisions; not for precise quantitative predictions
- **No Toxicity**: ADME only; use separate tools for safety assessment

**Model Accuracy (Typical):**
- LogP: R² = 0.85-0.95 (very good)
- Solubility: R² = 0.65-0.80 (moderate)
- HIA: Accuracy = 75-85% (good)
- BBB: Accuracy = 70-80% (moderate)
- Metabolic stability: R² = 0.60-0.75 (moderate)
- T1/2: R² = 0.50-0.65 (challenging)

## Version History

- **v1.0.0** (Current): Initial release with 20+ ADME endpoints, QED scoring, batch processing
- Planned: Integration with PK simulation, population variability modeling, formulation effects

---

**⚠️ CRITICAL DISCLAIMER: These predictions are computational estimates for prioritization and guidance only. They do NOT replace experimental ADME studies required for regulatory submissions or clinical decision-making. Always validate predictions with appropriate in vitro and in vivo assays before advancing compounds.**

## Input Validation

This skill accepts requests that match the documented purpose of `adme-property-predictor` and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

> `adme-property-predictor` only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

## Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.

## Inputs to Collect

- Required inputs: the user goal, the primary data or source file, and the requested output format.
- Optional inputs: output directory, formatting preferences, and validation constraints.
- If a required input is unavailable, return a short clarification request before continuing.

## Output Contract

- Return a short summary, the main deliverables, and any assumptions that materially affect interpretation.
- If execution is partial, label what succeeded, what failed, and the next safe recovery step.
- Keep the final answer within the documented scope of the skill.

## Validation and Safety Rules

- Validate identifiers, file paths, and user-provided parameters before execution.
- Do not fabricate results, metrics, citations, or downstream conclusions.
- Use safe fallback behavior when dependencies, credentials, or required inputs are missing.
- Surface any execution failure with a concise diagnosis and recovery path.

FILE:references/runtime_checklist.md
# Runtime Checklist

# 3D Molecule Ray Tracer

Advanced molecular visualization tool that generates professional-grade rendering scripts with cinematic effects for creating publication-quality and cover-worthy molecular images.

## When to Use

- Use this skill when the task is to Generate photorealistic rendering scripts for PyMOL and UCSF ChimeraX.
- Use this skill for data analysis tasks that require explicit assumptions, bounded scope, and a reproducible output format.
- Use this skill when you need a documented fallback path for missing inputs, execution errors, or partial evidence.

## Key Features

See `## Features` above for related details.

- Scope-focused workflow aligned to: Generate photorealistic rendering scripts for PyMOL and UCSF ChimeraX.
- Packaged executable path(s): `scripts/main.py`.
- Structured execution path designed to keep outputs consistent and reviewable.

## Dependencies

## Example Usage

See `## Usage` above for related details.

```bash
cd "20260318/scientific-skills/Data Analytics/3d-molecule-ray-tracer"
python -m py_compile scripts/main.py
python scripts/main.py --help
```

Example run plan:
1. Confirm the user input, output path, and any required config values.
2. Edit the in-file `CONFIG` block or documented parameters if the script uses fixed settings.
3. Run `python scripts/main.py` with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

## Implementation Details

See `## Workflow` above for related details.

- Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
- Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
- Primary implementation surface: `scripts/main.py`.
- Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
- Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

## Quick Check

Use this command to verify that the packaged script entry point can be parsed before deeper execution.

```bash
python -m py_compile scripts/main.py
```

## Audit-Ready Commands

Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths.

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
```

## Workflow

1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work.
2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions.
3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available.
4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items.
5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion.

  @ cover_render.pml
```

## Evaluation Criteria

### Success Metrics
- [ ] Successfully generates valid PyMOL/ChimeraX scripts
- [ ] Scripts execute without errors in target software
- [ ] Output images meet quality standards
- [ ] Handles edge cases gracefully

### Test Cases
1. **Basic Functionality**: Generate script for PDB ID → Valid script created
2. **File Input**: Generate script from PDB file → Valid script created
3. **Preset Override**: Custom parameters override preset → Correct settings applied
4. **Both Software**: Generate for PyMOL and ChimeraX → Both scripts valid

## Lifecycle Status

- **Current Stage**: Draft
- **Next Review Date**: 2026-03-15
- **Known Issues**: None
- **Planned Improvements**: 
  - Blender integration
  - AI-assisted composition suggestions
  - Real-time preview mode

## References

See `references/` for:
- PyMOL-specific rendering techniques
- ChimeraX lighting documentation
- Colorblind-friendly palettes
- Journal submission guidelines

## Limitations

- **Static Images Only**: Generates scripts for still images, not animations
- **Software Dependency**: Requires separately installed PyMOL or ChimeraX
- **Rendering Time**: High-quality renders can take 10-30 minutes per image
- **Learning Curve**: Advanced effects require understanding of photography concepts
- **File Sizes**: High-res images can be 10-50 MB each
- **No Automatic Layout**: Creates single images; figure assembly requires separate tools

---

**💡 Tip: For creating multiple related figures, save your complete scene setup (lighting, camera, colors) as a PyMOL session file (.pse) or ChimeraX session (.cxs), then modify only the specific elements needed for each figure. This ensures consistency across figure panels.**

## Output Requirements

Every final response should make these items explicit when they are relevant:

- Objective or requested deliverable
- Inputs used and assumptions introduced
- Workflow or decision path
- Core result, recommendation, or artifact
- Constraints, risks, caveats, or validation needs
- Unresolved items and next-step checks

## Error Handling

- If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
- If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
- If `scripts/main.py` fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
- Do not fabricate files, citations, data, search results, or execution outcomes.

## Input Validation

This skill accepts requests that match the documented purpose of `3d-molecule-ray-tracer` and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

> `3d-molecule-ray-tracer` only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

## Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.

# FAERS Multi-Drug Single-SOC Safety Comparison Research Planner

Generates a complete FAERS comparative pharmacovigilance study design from a user-provided drug set, comparator logic, and target SOC. Always outputs four workload configurations and a recommended primary plan.

## Supported Study Styles

- **A. Drug Class vs Active Comparator** — e.g., beta-blockers vs ACE inhibitors for psychiatric disorders
- **B. Within-Class Head-to-Head** — e.g., propranolol vs atenolol vs metoprolol for neuropsychiatric AEs
- **C. Single-SOC + Multi-PT Deepening** — SOC-level signal + clinically meaningful PT breakdown
- **D. Active-Comparator Restricted Disproportionality** — indication-restricted confounding control
- **E. Pharmacologic-Property Heterogeneity** — lipophilic vs hydrophilic, selective vs non-selective subgroups
- **F. Sensitivity-Analysis Strengthened Design** — post hoc indication adjustment, comparator robustness
- **G. Publication-Oriented Integrated Comparative Pharmacovigilance** — full pipeline with subgroup + PT + sensitivity

## Minimum User Input

- One drug or drug class + one comparator or comparator logic + one target SOC or AE domain

## Interface Contract

**Inputs:**
- `drug_set` — one or more drug names or a drug class (e.g., "beta-blockers", "propranolol, atenolol")
- `comparator` — active comparator drug or class (e.g., "ACE inhibitors", "lisinopril"); may be inferred if omitted
- `target_soc` — one MedDRA SOC or bounded AE domain (e.g., "Psychiatric disorders"); may be inferred if omitted
- `config_preference` *(optional)* — "Lite", "Standard", "Advanced", or "Publication+" to pre-select a plan

**Outputs:**
- Four-configuration comparison table (Lite / Standard / Advanced / Publication+)
- Recommended primary plan with justification
- Step-by-step workflow with module-level detail
- Figure plan and table plan
- Validation and robustness plan
- Risk review section
- Minimal executable version (2–3 week path)
- Publication upgrade path table

**Integration note:** Outputs are structured text plans suitable for handoff to data-analysis skills (R/Python pipeline generators) or academic-writing skills.

## Example Inputs

**Example A (Canonical within-class):**
> "Compare beta-blockers (propranolol, atenolol, metoprolol) vs lisinopril for psychiatric adverse events in FAERS. Give me all four configurations."

**Example B (Minimal executable):**
> "I need a quick 3-week FAERS study comparing fluoroquinolones vs beta-lactams for tendon adverse events. Minimal plan only."

## Step-by-Step Execution

### Step 1: Infer Study Type
Identify:
- Drug set and comparator set
- Target SOC and key PTs (if specified)
- Comparison type: class vs class, within-class, subgroup vs subgroup
- Whether active-comparator restricted disproportionality is justified (shared indication required)
- Whether PT-level deepening is central or supportive
- Whether pharmacologic subgroup contrast is biologically motivated
- Resource constraints: public OpenFDA only, raw FAERS, single SOC

### Step 2: Output Four Configurations

Always generate all four:

| Config | Goal | Timeframe | Best For |
|--------|------|-----------|----------|
| **Lite** | Crude + adjusted ROR, one SOC, one comparator | 2–4 weeks | Quick signal check, pilot |
| **Standard** | Full active-comparator design + PT deepening + within-class | 5–8 weeks | Core publishable paper |
| **Advanced** | Standard + pharmacologic subgroup + post hoc sensitivity + richer PT hierarchy | 8–13 weeks | Competitive journal target |
| **Publication+** | Advanced + alternate comparator robustness + richer figure logic + real-world validation suggestions | 12–18 weeks | High-impact submission |

For each configuration describe: goal, required data, major modules, expected workload, figure set, strengths, weaknesses.

### Step 3: Recommend One Primary Plan
Select the best-fit configuration and explain why given drug class biology, comparator suitability, SOC scope, 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.

**Core modules to address when relevant:**

**Data Access & Retrieval**
- OpenFDA API or FAERS quarterly JSON download
- Time-window definition (e.g., 2013–present or bounded period)
- Duplicate case handling (OpenFDA has partial deduplication; note if using raw FAERS)
- Justify OpenFDA vs raw FAERS based on preprocessing needs

**Data Quality Gate** *(apply before proceeding)*
- Minimum case count: require n ≥ 30 cases per drug group before proceeding; if n < 30, flag as underpowered and recommend expanding time window or broadening drug-name regex
- API failure fallback: if OpenFDA API is unavailable, use FAERS quarterly ASCII file downloads from FDA website (https://fis.fda.gov/extensions/FPD-QDE-FAERS/FPD-QDE-FAERS.html); provide download path in the plan
- Sparse indication fields: if indication completeness < 20% of cases, note in limitations and recommend (a) reporting complete cases only as sensitivity, or (b) using drug-class indication as proxy; do not treat sparse indication as grounds for abandoning comparator restriction
- Zero-case scenario: if a key PT returns 0 cases for one drug arm, flag as unanalyzable for that PT; remove from primary table but include in supplementary

**Drug Normalization & Case Cleaning**
- Regular-expression medicinal-product name normalization
- Mapping to generic names via RxNorm / ATC / OHDSI
- Role-code filtering: retain primarysuspect (`PS`) only; note `SS`/`C`/`I` exclusions
- Duplicate removal (patient + event + date logic)
- Output: clean drug-indexed case file with counts per drug

**Comparator Definition**
- Active comparator selection: shared therapeutic indication required
- Justify comparator by indication overlap; exclude classes with confounding concern
- Head-to-head within-class comparator logic if applicable
- Output: comparator group definition table with justification

**Outcome (SOC + PT) Definition**
- MedDRA SOC assignment (one primary SOC; optionally one adjacent SOC)
- PT list construction: select 5–12 clinically meaningful PTs within the SOC
- Broad SOC signal + specific PT deepening hierarchy
- Output: SOC/PT definition table with MedDRA codes

**Descriptive Case Characterization**
- Demographics: age (median/IQR), sex, weight, country, reporter type
- Indication summary, serious outcome counts
- Time-to-onset (TTO): median days from drug start to AE onset (if available)
- Output: Table 1 — case characteristics by drug group

**Crude ROR Analysis**
- 2×2 contingency table per drug per outcome (SOC and PT)
- ROR = (a/b) / (c/d); 95% CI via Woolf method
- Signal threshold: lower CI > 1.0 as primary; report all with CI
- Output: crude ROR table per drug per SOC/PT

**Adjusted ROR (Logistic Regression)**
- Logistic regression: outcome ~ drug_group + covariates
- Covariates: age, sex, weight, key comorbidities relevant to indication (e.g., hypertension, HF, AF for cardiovascular drugs)
- Reference: active comparator group as reference level
- Report aROR with 95% CI; compare crude vs adjusted
- Failure point: sparse cells for rare PTs → Firth penalized logistic or note instability

**Within-Class Head-to-Head Comparison**
- Pairwise drug comparisons within class (e.g., propranolol vs atenolol)
- Logistic model with one drug as reference
- Interpret directional consistency across PTs
- Note: for ≥ 4 pairwise comparisons, apply Bonferroni or FDR correction; report uncorrected and corrected results side by side

**Pharmacologic Subgroup Comparison** (Advanced+)
- Map each drug to pharmacologic property subgroup (e.g., lipophilic vs hydrophilic)
- Compare aROR distributions across subgroups
- Frame as hypothesis-supporting, not causal proof

**Sensitivity Analysis** (Standard+)
- Post hoc: add non-primary indication adjustment (e.g., migraine, anxiety for beta-blockers)
- Alternate comparator robustness: swap one comparator; check directional stability
- Role-code sensitivity: include SS cases and compare
- Output: sensitivity table alongside primary results

### Step 5: Figure Plan

| Figure | Content |
|--------|---------|
| Fig 1 | Overall workflow / study design schematic |
| Fig 2 | Case selection flowchart (CONSORT-style) |
| Fig 3 | SOC-level forest plot (aROR per drug vs comparator) |
| Fig 4 | PT-level forest plot (aROR per drug per key PT) |
| Fig 5 | Within-class head-to-head comparison figure |
| Fig 6 | Time-to-onset summary (violin or box) per drug group |
| Fig 7 | Sensitivity analysis comparison (primary vs sensitivity aROR) |
| Table 1 | Drug normalization + comparator definition |
| Table 2 | Descriptive case characteristics |
| Table 3 | Crude + adjusted ROR summary (SOC + PT) |
| Table 4 | Sensitivity analysis summary |

### Step 6: Validation and Robustness Plan

Distinguish clearly:
- **Data-cleaning robustness** — normalization consistency, duplicate handling, role-code restriction
- **Comparator robustness** — indication overlap validity, inappropriate comparator avoidance
- **Adjusted signal support** — crude vs adjusted ROR comparison; covariate transparency
- **Within-class heterogeneity evidence** — directional consistency across drugs and PTs
- **Sensitivity-analysis support** — stability of findings under alternate model specifications

State what each layer proves and what it does not prove:
- Disproportionality signal ≠ incidence estimate
- Adjusted ROR controls measured confounders, not unmeasured indication bias
- Active comparator reduces but does not eliminate confounding by indication
- PT-level signals are exploratory without multiplicity correction unless pre-specified

### Step 7: Risk Review

Always include a self-critical section addressing:
- Strongest part: active-comparator restriction + logistic adjustment
- Most assumption-dependent: completeness of indication fields in FAERS (often sparse)
- Most likely false-positive source: multiple PT comparisons without multiplicity correction
- Easiest to overinterpret: ROR as "risk" rather than "reporting proportion difference"
- Most likely reviewer criticisms: underreporting bias, notoriety bias, residual confounding by indication, drug-name misclassification, no external population-based validation
- Revision if findings fail: switch to PT-level primary outcome; restrict to highest-quality reporter types (HCP-only); expand covariate set

### Step 8: Minimal Executable Version

OpenFDA only, one drug class + one active comparator, one SOC, primary suspect restriction, drug normalization, crude + adjusted ROR, 3–5 key PTs, one summary table + one forest plot. 2–3 week timeline.

### Step 9: Publication Upgrade Path

| Addition | Publication Gain | Effort |
|----------|-----------------|--------|
| Add second active comparator | High (comparator robustness) | Low |
| Add within-class head-to-head | High (heterogeneity story) | Low–Medium |
| Add time-to-onset summary | Medium | Low |
| Add pharmacologic subgroup comparison | Medium (mechanistic framing) | Medium |
| Add post hoc sensitivity analysis | High (reviewer defense) | Low |
| Expand PT architecture to 10–12 PTs | Medium | Low |
| Add HCP-only reporter sensitivity restriction | Medium | Low |

## 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 disproportionality evidence, adjusted signal support, heterogeneity evidence, and sensitivity support.
5. Never treat FAERS signals as incidence estimates — label as reporting disproportionality.
6. Never overclaim causal drug effects from disproportionality alone.
7. Do not force broad all-SOC scans when user clearly wants one SOC or narrow domain.
8. Do not ignore comparator suitability; flag if indication overlap is weak.
9. Do not ignore drug-name misclassification risk — always include normalization step.
10. If user provides limited detail, infer a reasonable default design and state assumptions clearly.

## Input Validation

This skill accepts: a drug set (one or more drugs or a drug class) + a comparator (or inferrable comparator) + a target SOC or AE domain, submitted for FAERS comparative pharmacovigilance study design.

**Out-of-scope response templates:**

*If the user provides only one drug with no comparator and no SOC:*
> "To design a FAERS comparative study, this skill needs at minimum: (1) a target drug or drug class, (2) a comparator, and (3) a target adverse event domain. I'll infer a reasonable comparator and SOC based on the drug's indication — please confirm or correct my assumptions before proceeding."

*If the user requests an all-SOC sweep or pan-MedDRA signal scan:*
> "This skill is designed for single-SOC comparative pharmacovigilance designs. An all-SOC disproportionality sweep is a different study type outside this scope. I can help you: (a) identify the highest-priority SOC for your drug and design a focused study there, or (b) describe how an all-SOC PRR/EBGM screen would differ methodologically. Which would be more useful?"

*If the user asks to frame FAERS disproportionality results as causal evidence without caveats:*
> "FAERS disproportionality analysis (ROR/PRR) cannot establish causality — it quantifies reporting proportion differences, not incidence or risk. This skill will always include appropriate epistemic caveats. I can design the strongest possible comparative pharmacovigilance study with active-comparator restriction and sensitivity analysis to maximize the evidentiary weight of the findings."

*If the request is unrelated to FAERS/pharmacovigilance study design:*
> "FAERS Multi-Drug SOC Planner is designed to generate comparative pharmacovigilance study designs using FAERS or OpenFDA data. Your request appears to be outside this scope. Please use a more appropriate tool for your task."

| **B. Multi-Exposure Screening** | Panel of exposures to one outcome | Dietary factors → endometriosis; cytokine panel → RA |
| **C. Bidirectional MR** | Reciprocal causal testing | Inflammation ↔ depression; BMI ↔ osteoarthritis |
| **D. Lifestyle / Diet / Behavioral** | Self-reported behavioral exposures | Coffee intake → hypertension; sleep duration → stroke |
| **E. Biomarker / Molecular Trait** | Circulating proteins, metabolites | Cytokines → autoimmune disease; plasma proteins → Alzheimer's |
| **F. Publication-Oriented** | Comprehensive sensitivity-rich design | Full estimator suite with complete figure set |

## Minimum User Input

- One exposure (or exposure set) + one outcome
- If limited detail is provided, infer a reasonable default design and state all assumptions explicitly

## Step-by-Step Execution

### Step 1: Infer Study Type

Identify:

- User goal: screening, bidirectional, causal verification, or publication strength
- Whether MVMR or colocalization is justified
- Time or resource constraints stated by the user

### Step 2: Output Four Configurations

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

| Config | Goal | Timeframe | Best For |
|--------|------|-----------|----------|
| **Lite** | Fast minimal causal test | 2–4 weeks | Quick launch, 1 exposure × 1 outcome |
| **Standard** | Publication-ready core MR | 4–8 weeks | Single or small panel + sensitivity suite |
| **Advanced** | Robust multi-extension design | 8–14 weeks | Bidirectional, MVMR, replication GWAS |
| **Publication+** | High-impact comprehensive paper | 12–20 weeks | Full sensitivity, MVMR, colocalization, power |

### Step 3: Recommend One Primary Plan

Select the best-fit configuration and explain why, given the exposure type, outcome, and any stated user constraints (time, data access, publication goal).

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

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

**Core modules to address when relevant:**

- Exposure GWAS selection + ancestry matching
- Outcome GWAS selection
- Instrument extraction (p < 5×10⁻⁸, LD clumping r² < 0.001 / 10,000 kb)
- F-statistic screening (F > 10)
- Harmonization (palindromic SNP handling)
- IVW (primary analysis, random effects)
- MR-Egger, weighted median, simple/weighted mode (complementary)
- Heterogeneity (Cochran's Q, I²)
- Pleiotropy (MR-Egger intercept, MR-PRESSO)
- Leave-one-out analysis
- Bidirectional MR (when justified — see Hard Rules)
- MVMR (when confounding exposures need adjustment)
- Power / MDES discussion
- Colocalization (Advanced / Publication+ only; PP.H4 > 0.8 standard)

**Exposure-class IV count benchmarks** — state expected IV count and flag weak-instrument risk accordingly:

→ Full benchmarks by exposure class: [references/iv_benchmarks.md](references/iv_benchmarks.md)

**GWAS data sources by exposure class:**

→ Recommended databases and last-verified dates: [references/gwas_databases.md](references/gwas_databases.md)

**Fault tolerance guidelines:**
- If the target GWAS is unavailable: state this explicitly, suggest the closest publicly available alternative, and recommend the Lite configuration until data access is confirmed
- If IV count falls below 3: warn the user that MR is not feasible with current instruments; suggest waiting for larger GWAS or pivoting to a proxy exposure
- If F-statistic < 10 for all IVs: do not proceed with IVW as primary; escalate to weak-instrument-robust methods (LIML, sisVIVE) and note this as a study limitation

### Step 5: Figure and Deliverable Plan

Always list:
- Scatter plots (exposure–outcome per estimator)
- Forest plots (leave-one-out)
- Funnel plots (pleiotropy visual)
- Summary results table (all estimators)
- Sensitivity analysis table

### Step 6: Validation and Robustness Plan

State what each layer proves and what it does not prove. Distinguish:
- **Primary MR evidence**: IVW result + instrument validity checks (F > 10, no strong pleiotropy signal)
- **Sensitivity support**: estimator consistency across MR-Egger, weighted median, mode; Cochran Q non-significant
- **Higher-tier causal strengthening**: MVMR (adjusts for correlated exposures), bidirectional MR (rules out reverse causation), colocalization (rules out LD confounding)

### Step 7: Risk Review

Always include a self-critical section addressing:
- Strongest part of the design
- Most assumption-dependent part
- Most likely source of false positives
- Easiest part to overinterpret
- Most likely reviewer criticisms: weak instruments, pleiotropy, ancestry mismatch, sample overlap, multiple-testing (for screening studies), behavioral phenotype noise, insufficient IV count for dietary/microbiome exposures
- Revision strategy if first-pass findings fail

### Step 8: Minimal Executable Version

Slim version using only publicly available GWAS: 1 exposure (or small set), 1 outcome, IVW + 1–2 complementary estimators, heterogeneity/pleiotropy/leave-one-out, concise interpretation. Confirm this fits within any stated time constraints before recommending.

### Step 9: Publication Upgrade Path

Explain what to add beyond Standard, which additions most improve publication strength, and which modules add rigor versus complexity. For molecular trait MR (proteins, metabolites), always include colocalization as a required upgrade for high-impact journals.

## R Code Framework Guidelines

When providing R code examples or frameworks:
- Always use the `TwoSampleMR` package (CRAN) as the primary tool
- Mark all GWAS IDs as examples with an explicit inline comment: `# EXAMPLE ID — replace with your target phenotype ID`
- Do not present example IDs as validated or guaranteed to resolve correctly
- Provide the IEU Open GWAS API query pattern so users can search for their own phenotype IDs

**Standard R framework template:**

```r
library(TwoSampleMR)
library(MRPRESSO)

# Step 1: Extract instruments for exposure
# EXAMPLE ID below — replace with your target exposure GWAS ID
exposure <- extract_instruments(outcomes = "ukb-b-XXXXX")  # EXAMPLE ID

# Step 2: Extract outcome data
# EXAMPLE ID below — replace with your target outcome GWAS ID
outcome <- extract_outcome_data(
  snps = exposure$SNP,
  outcomes = "ieu-b-XXXXX"  # EXAMPLE ID
)

# Step 3: Harmonise
harmonized <- harmonise_data(exposure, outcome)

# Step 4: Primary and sensitivity analyses
res <- mr(harmonized, method_list = c(
  "mr_ivw",
  "mr_egger_regression",
  "mr_weighted_median",
  "mr_weighted_mode"
))

# Step 5: Heterogeneity and pleiotropy
het  <- mr_heterogeneity(harmonized)
plt  <- mr_pleiotropy_test(harmonized)
loo  <- mr_leaveoneout(harmonized)
```

To find valid GWAS IDs: `ao <- available_outcomes(); View(ao)`

## 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 primary MR evidence, sensitivity support, and higher-tier causal strengthening.
5. Do not force bidirectional or MVMR if the topic does not justify it.
6. Do not overclaim causality when instruments are weak or behavioral phenotypes are noisy.
7. Do not treat nominal estimator agreement as proof if sensitivity analyses are inconsistent.
8. Do not ignore ancestry mismatch or sample-overlap concerns.
9. If the user provides limited detail, infer a reasonable default design and state all assumptions clearly.
10. Do not produce only a literature summary or flat methods list.
11. **Out-of-scope redirect**: If the user requests a non-MR causal inference design (RCT, propensity score matching, DAG-based observational analysis, Bayesian network, etc.), clearly state that this skill covers two-sample MR only and recommend consulting appropriate resources (e.g., CONSORT for RCTs, STROBE for observational studies).

## Input Validation

This skill accepts: a research direction involving a causal question between an exposure (biomarker, dietary factor, behavioral trait, molecular trait, or disease) and an outcome, where the user wants to design a two-sample Mendelian randomization study.

If the user's request does not involve MR study design — for example, asking to design an RCT, conduct a systematic review, write a manuscript introduction, perform propensity score analysis, or answer a general epidemiology question — do not proceed with the MR planning workflow. Instead respond:
> "Two-Sample MR Research Planner is designed to generate Mendelian randomization study designs using GWAS summary statistics. Your request appears to be outside this scope. Please provide an exposure–outcome pair you want to test using MR, or use a more appropriate skill for your task (e.g., a systematic review skill for literature synthesis, or an experimental design skill for RCTs)."

## Ancestry Matching Guidance

- Default to **European ancestry (EUR)** GWAS pairs for primary analysis when available; this minimizes LD structure mismatch.
- For non-EUR populations: use **EAS** (BBJ, CKB, UKBB-Asian) or **AFR** (AWI-Gen, H3Africa) specific GWAS when available.
- **Do not mix ancestries** across exposure and outcome GWAS without explicitly modeling this as a limitation.
- Cross-ancestry MR is an active research area; flag it as exploratory if used.

---

## Sample Overlap Check

- Check whether the exposure and outcome GWAS share participants (common sources: UK Biobank, 23andMe).
- Substantial sample overlap biases IVW toward the observational estimate; use GSMR with HEIDI-outlier test or sensitivity analyses robust to overlap.
- Report overlap status in the methods section.

# IV Count Benchmarks and Weak-Instrument Risk by Exposure Class

> Use this table during Step 4 (instrument extraction) to set expectations, flag weak-instrument risk, and communicate feasibility to the user.

## How to Use This Reference

1. Identify the exposure class from Step 1.
2. Look up the expected IV count range for that class.
3. Compare against the actual IV count obtained after clumping (p < 5×10⁻⁸, r² < 0.001 / 10,000 kb).
4. Apply the risk flag and adjust the recommended configuration and methods accordingly.

---

## IV Count Benchmarks

| Exposure Class | Typical IV Count (post-clumping) | Weak-Instrument Risk | Recommended Action |
|---|---|---|---|
| **Anthropometric** (BMI, height, waist-hip ratio) | 50–500+ | Very Low | Standard IVW appropriate |
| **Blood lipids** (LDL, HDL, TG, TC) | 50–300+ | Very Low | Standard IVW appropriate |
| **Biomarker — well-powered** (uric acid, CRP, insulin) | 10–100 | Low | Standard IVW appropriate |
| **Biomarker — moderately powered** (most single biomarkers) | 5–30 | Low-Moderate | Check mean F-statistic; note if < 20 |
| **Protein (cis-pQTL)** | 1–10 | Moderate | Use cis-only; check colocalization (PP.H4 > 0.8) |
| **Protein (trans-pQTL)** | Variable | High (pleiotropy) | Use only as supplementary; flag horizontal pleiotropy risk |
| **Metabolite (NMR panel)** | 2–20 per metabolite | Moderate | May need weighted median as primary if < 5 IVs |
| **Gene expression (eQTL)** | 1–5 per gene | Moderate | cis-eQTL preferred; trans-eQTL high pleiotropy risk |
| **Dietary trait** | 2–15 | High | Flag if < 10; state weak-instrument limitation explicitly |
| **Behavioral / Lifestyle** | 3–50 | Moderate-High | Self-report noise amplifies weak IV problem |
| **Sleep phenotypes** | 5–30 (insomnia), 2–10 (duration) | Moderate | Objective actigraphy GWAS preferred |
| **Gut microbiome (taxon-level)** | 1–5 | Very High | Many taxa: 0 genome-wide significant SNPs; flag as exploratory |
| **Psychiatric phenotype** | 10–200 (varies by disorder) | Low-Moderate | PGC GWAS sample sizes growing rapidly; check latest release |
| **Binary disease outcome as exposure** | 5–50 | Moderate | Case-control GWAS; liability-scale effect sizes needed |

---

## F-Statistic Interpretation

The F-statistic for each instrument is: **F = (β/SE)²**

The mean F-statistic across all IVs indicates overall instrument strength:

| Mean F | Interpretation | Action |
|---|---|---|
| > 50 | Strong instruments | Standard analysis |
| 20–50 | Acceptable instruments | Proceed; note in limitations |
| 10–20 | Borderline weak | Add weighted median as primary fallback; report mean F |
| < 10 | Weak instruments | Do not use IVW as primary; use weak-IV-robust methods (LIML, TSLS with robust SE); frame as exploratory |
| < 5 | Severely weak | Do not conduct MR; recommend waiting for larger GWAS |

---

## Weak-Instrument Mitigation Strategies

When IV count is low or F-statistic is borderline:

1. **Lower the p-value threshold** to p < 5×10⁻⁶ (use with caution; increases pleiotropy risk; always report alongside genome-wide threshold results)
2. **Use GSMR** (Genome-wide Summary-data-based MR) which is more efficient with lower IV counts
3. **Report the Weighted Median estimator** as the primary result when N_IVs < 10 (it tolerates up to 50% invalid instruments)
4. **Conduct a power calculation** using mRnd or the TwoSampleMR power function to estimate detectable effect sizes
5. **Frame the study as exploratory** and recommend replication when a better-powered GWAS becomes available

---

## Special Cases

### Bidirectional MR IV Requirements
Both directions require sufficient instruments independently. If exposure A → outcome B has 30 IVs but outcome B → exposure A has only 2 IVs, the reverse direction is not feasible. Report this asymmetry explicitly.

### Multi-Exposure Screening (Panel MR)
- Apply FDR correction (Benjamini-Hochberg) when screening ≥ 5 exposures
- Apply Bonferroni correction if ≥ 10 exposures
- Report both corrected and uncorrected p-values
- For dietary panels: expect most exposures to have < 10 IVs; prioritize exposures with the strongest biological prior

### Protein MR (Proteome-Wide MR)
- Use cis-pQTLs only as primary IVs (within ±1 Mb of the gene)
- Colocalization (PP.H4 > 0.8 using coloc or HyPrColoc) is required before drawing causal conclusions for high-impact publications
- SOMAscan and Olink platforms measure overlapping but non-identical protein sets; specify the platform used

# Network Toxicology + Molecular Docking Research Planner

Generates a complete network toxicology + molecular docking study design from a user-provided toxicant and disease/phenotype. Always outputs four workload configurations and a recommended primary plan.

## Input Validation

This skill accepts: a toxicant (environmental chemical, endocrine disruptor, heavy metal, food contaminant, pharmaceutical residue, or consumer product chemical) paired with a disease or phenotype, for which the user wants to generate a network toxicology + molecular docking research design.

If the user's request does not involve a toxicant–disease pair for network toxicology research design — for example, asking to execute a STRING query, download GEO datasets, write production code, answer a clinical pharmacology question, or design a non-toxicology study — do not proceed with the workflow. Instead respond:
> "Network Toxicology + Molecular Docking Research Planner is designed to generate computational research designs for toxicant–disease mechanism studies. Please provide a toxicant and a disease or phenotype. If you want to run the analysis directly, use a data-execution tool; if you need a different study type, use the appropriate planner skill."

**Minimum required input:** one toxicant + one disease or phenotype.  
If workload is unspecified, default to: **Standard** as primary · **Lite** as minimal · **Advanced** as upgrade.

---

## Step 1 — Infer Study Context

Read → `references/decision-logic.md`

Identify: toxicant class · disease type · whether docking is central or supportive · validation feasibility · resource constraints · publication ambition · whether input involves multiple toxicants (→ Pattern F in Step 2).

---

## Step 2 — Select Study Pattern

Read → `references/study-patterns.md`

Match to one of six canonical design styles (A–F). State which pattern applies and why.

| Pattern | When to use |
|---|---|
| A. Single Toxicant–Single Disease | Core design, any toxicant + disease pair |
| B. Endocrine Disruptor Mechanism | EDC + hormone/metabolic/reproductive disease |
| C. Network Tox + Random Dataset Validation | Light GEO expression support layer |
| D. PPI Hub Gene + Docking-Centered | Compact publishable hub+docking focus |
| E. Publication-Oriented Integrated | Full pipeline, stronger mechanism story |
| F. Multi-Toxicant Comparative | 2–3 toxicants + one disease, comparative overlap analysis |

---

## Step 3 — Generate Four Configurations

Read → `references/configurations.md`

Always output all four tiers — **except** when the user explicitly requests only one tier AND the request is time- or resource-constrained (e.g., "2-week Lite only"). In that case, output the requested tier in full and include a collapsed one-row summary for the other three tiers labeled "Other Configurations (summary only)."

Recommend one tier. Justify the choice.

| Tier | Best for | Workload | Target sources | Docking targets |
|---|---|---|---|---|
| **Lite** | Quick launch, skeleton paper | 2–4 wk | 2 | Top 3 |
| **Standard** | Mainstream publication *(default)* | 4–6 wk | ≥2 | Top 3–5 |
| **Advanced** | Competitive journals | 6–10 wk | ≥3 + harmonization | Top 5 + rationale |
| **Publication+** | High-impact, multi-layer | 10–16 wk | ≥3 + harmonization | Multi-target comparison |

---

## Step 4 — Expand Primary Workflow

For each step follow the **step-level standard** (every step must include):  
`Step Name / Purpose / Input / Method / Key Parameters / Expected Output / Failure Points / Alternative Methods`

Draw modules from → `references/modules.md`

---

## Step 5 — Mandatory Output Sections

Read → `references/output-standard.md`

Every response must contain all nine parts (A–I):

1. **Core research question** (one sentence + 2–4 specific aims)
2. **Configuration overview** (4-tier table)
3. **Recommended primary plan** + rationale
4. **Step-by-step workflow** (expanded for recommended tier)
5. **Target & dataset framework**
6. **Figure & deliverable list**
7. **Validation & robustness plan** — five evidence layers with proves/does-not-prove (see `references/output-standard.md` Part G)
8. **Minimal executable version** (Lite-level, 2–4 weeks)
9. **Publication upgrade path**

---

## Article Pattern Coverage

Plans must address these patterns when relevant:

| Pattern | Requirement |
|---|---|
| Toxicant target prediction + disease target intersection | Required |
| PPI + hub gene discovery (STRING + Cytoscape + CytoHubba) | Required |
| GO / KEGG enrichment | Required |
| Docking of top hub genes (CB-Dock2 or AutoDock Vina) | Required |
| GEO / random expression validation | Recommended (Standard+, when dataset available) |
| Endocrine/metabolic pathway interpretation | Recommended (if biologically relevant) |
| Multiple target-prediction databases | Required (Standard+) |
| Integrated mechanism model figure | Required |
| Wet-lab follow-up suggestion | Optional (Publication+) |

---

## Hard Rules

1. Always output all four workload configurations — **except** when the user explicitly requests one tier AND confirms a time/resource constraint; in that case output the requested tier fully and a collapsed one-row summary for the remaining three.
2. Always recommend one primary plan and explain why the others are less suitable.
3. Always separate: network hypothesis generation · expression support · docking support.
4. Never claim docking proves in vivo binding or biological activity.
5. Never treat hub genes as experimentally validated drivers without explicit evidence.
6. Never overclaim causality from target overlap and enrichment alone.
7. Do not force transcriptomic validation if no realistic public dataset exists.
8. Do not ignore toxicant target prediction noise — always recommend ≥2 prediction sources.
9. Never list tools without explaining why they are used.
10. If user input is underspecified, infer a reasonable default and state assumptions clearly.
11. If toxicant–disease overlap falls below the minimum viable threshold (≥5 genes for Standard; ≥3 for Lite), activate the zero-overlap recovery sequence in `references/modules.md` before proceeding.

## Reviewer Risk Register

| Risk | Mitigation |
|---|---|
| Toxicant target prediction noise | Use ≥2 independent prediction sources; report union and intersection counts |
| Disease target database bias (GeneCards keyword sensitivity) | Apply score filters (GeneCards ≥1, DisGeNET ≥0.1); use ≥2 disease databases |
| Hub-gene instability across algorithms | Report MCC results; optionally run Degree or Betweenness as sensitivity check |
| Weak transcriptomic validation (small GEO cohort) | Acknowledge sample size; label as supportive only; avoid over-interpreting t-test p-values |
| Docking overinterpretation | State binding energy is computational only; in vitro confirmation required for causal claims |
| No in vivo / in vitro validation | Acknowledge as major limitation; suggest qPCR, cell viability, or animal model follow-up |
| Pathway enrichment as causal mechanism | Use hedged language; note enrichment is associational, not mechanistic proof |
| AlphaFold structure used for docking | Flag explicitly; prefer experimental PDB structures (resolution < 3.0 Å) |

# Decision Logic

Before generating the study plan, infer the following five dimensions:

## 1. User Objective
- identify toxicant-related targets
- discover hub genes
- explain mechanism
- build a docking-supported toxicology paper
- produce a publication-ready study

## 2. Toxicant Class
- endocrine-disrupting chemical (EDC)
- heavy metal
- food contaminant
- pharmaceutical residue
- mixed environmental pollutant
- consumer product chemical

## 3. Is Network Toxicology Appropriate?
If yes → specify target prediction feasibility, disease target database coverage.  
If no → say so clearly and suggest alternatives.

## 4. Is Docking Central or Supportive?
**Central**: emphasize receptor selection, PDB quality, docking rationale, and binding interpretation.  
**Supportive**: keep docking compact; prioritize network/pathway logic.

## 5. Resource Constraints
- Public-data-only → prioritize Lite / Standard  
- Publication-oriented → prioritize Standard / Advanced / Publication+
- No wet lab → confirm all modules are computational

- STRING PPI construction (confidence threshold ≥ 0.7 for Standard+)
- Cytoscape import + layout
- CytoHubba → hub gene screening (MCC algorithm default; Degree / Betweenness as alternatives)
- Network visualization

## Enrichment & Mechanism
- Entrez ID conversion (clusterProfiler)
- GO enrichment (BP / CC / MF)
- KEGG enrichment
- Visualization: bar plots, bubble plots
- Threshold: p.adjust < 0.05, q < 0.05
- Tools: clusterProfiler, enrichplot, ggplot2, org.Hs.eg.db

## Expression Validation
- GEO dataset search (keywords: disease name + "Homo sapiens")
- Disease vs. control group definition
- Core gene expression comparison (t-test or Wilcoxon)
- Boxplot visualization
- Acknowledge sample-size limits explicitly

## Molecular Docking
- Ligand: PubChem SDF download → format conversion
- Receptor: UniProt accession → PDB structure retrieval
- Docking tool: CB-Dock2 (primary) or AutoDock Vina
- Score interpretation: binding energy (kcal/mol); lower = stronger affinity
- Pose visualization: CB-Dock2 3D viewer or PyMOL
- 2D interaction mapping: Discovery Studio Visualizer
- Target selection: top hub genes with available high-resolution PDB structures

## Selection Rules for Docking Targets
1. Must be in the hub gene list
2. Must have a high-quality PDB structure (resolution < 3.0 Å preferred)
3. Prioritize targets with known ligand-binding pockets
4. If no structure available, use AlphaFold model with explicit caveat

## Minimum Viable Overlap Thresholds & Zero-Overlap Recovery

### Thresholds

| Tier | Minimum overlap genes to proceed |
|---|---|
| Lite | ≥ 3 genes |
| Standard | ≥ 5 genes |
| Advanced / Publication+ | ≥ 5 genes (≥ 10 recommended for robust PPI) |

### Zero-Overlap Recovery Sequence

If the toxicant–disease overlap falls below the minimum threshold, apply the following steps **in order** before declaring infeasibility:

1. **Loosen disease target filter**: reduce GeneCards relevance score cutoff from ≥1 to ≥0.5; reduce DisGeNET GDA score from ≥0.1 to ≥0.05
2. **Expand toxicant target sources**: if only 2 prediction sources used, add a third (e.g., TargetNet, SEA — see Toxicant Target Retrieval module)
3. **Manual literature curation**: search PubMed for direct toxicant–gene associations; add up to 10 curated targets with source citations; label as "manually curated — lower confidence"
4. **Switch enrichment strategy**: if overlap < 3 genes after steps 1–3, pivot to pathway-level overlap (KEGG pathway → gene list expansion) rather than direct gene overlap
5. **If still empty after all steps**: inform the user that no computationally recoverable overlap was found; recommend (a) broader disease phenotype re-specification (e.g., switch from a specific disease subtype to the parent disease), (b) a different toxicant from the same chemical class, or (c) a literature-only mechanism review as an alternative study format

**Activate this sequence whenever Hard Rule 11 fires.** Document all recovery steps taken in Part G (Validation & Robustness) of the output.

## Part G — Validation & Robustness

Explicitly separate all five layers. For each layer state what it proves AND what it does not prove:

1. **Target-source robustness**
   - Multi-database toxicant target coverage (≥2 sources)
   - Multi-database disease target coverage (≥2 sources)
   - Overlap size and consistency
   - *Proves*: shared molecular target space exists
   - *Does not prove*: toxicant engages these targets in vivo

2. **Network robustness**
   - STRING confidence threshold (≥0.7 for Standard+)
   - Hub algorithm choice (MCC default) + optional sensitivity
   - *Proves*: network centrality of candidate hubs
   - *Does not prove*: hub genes are causal drivers of toxicity

3. **Expression support**
   - GEO dataset selection logic + sample size
   - Disease vs. control comparison of core genes
   - Boxplot + t-test (acknowledge limits)
   - *Proves*: core genes are dysregulated in disease context
   - *Does not prove*: dysregulation is caused by the specific toxicant

4. **Docking support**
   - Ligand/receptor preprocessing (PDB quality, resolution)
   - Binding energy range and pose selection
   - 3D/2D visualization
   - *Proves*: computational binding feasibility
   - *Does not prove*: direct biological activity or in vivo binding

5. **Enrichment support**
   - GO/KEGG pathway associations (p.adjust < 0.05)
   - Pathway narrative consistency with known toxicant biology
   - *Proves*: pathway-level associations in target set
   - *Does not prove*: causal mechanism — associational only

6. **Reviewer risk points**: list ≥4 likely criticisms with responses
7. **Overclaim risks**: what the design cannot prove

- Which additions improve publication strength most
- Which improve rigor vs. which mostly increase complexity
- Typical upgrade modules: GEO validation · second validation dataset · alternative hub algorithm · stronger docking rationale · disease subtype refinement · wet-lab suggestions

FILE:references/study-patterns.md
# Study Patterns (A–E)

## A. Single Toxicant–Single Disease Design
**When**: one toxicant + one disease/phenotype.  
**Examples**: triclosan + PMOP · BPA + endometriosis · cadmium + CKD · PFAS + metabolic syndrome.  
**Logic**: retrieve toxicant targets → retrieve disease targets → calculate overlap → construct PPI → identify hub genes → GO/KEGG enrichment → expression validation (if available) → dock to core proteins.

## B. Endocrine Disruptor Mechanism Design
**When**: toxicant is an EDC; user wants endocrine-focused interpretation.  
**Examples**: triclosan + bone metabolism · parabens + thyroid dysfunction · BPA + reproductive disorders.  
**Logic**: collect EDC targets → retrieve endocrine-related disease targets → identify overlapping targets → enrich endocrine/metabolic pathways → dock to hormone-related and signaling targets → emphasize endocrine disruption + metabolic signaling.

## C. Network Toxicology + Random Dataset Validation
**When**: user wants a lightweight expression validation layer.  
**Logic**: identify toxicant–disease overlap → screen hub genes → retrieve one relevant GEO dataset → compare core gene expression control vs. disease → boxplots/t-tests as supportive validation → enrichment + docking.

## D. PPI Hub Gene + Docking-Centered Design
**When**: user wants compact but publishable workflow focused on hub genes and docking.  
**Examples**: environmental pollutant + disease risk · food contaminant + organ toxicity.  
**Logic**: predict toxicant targets → collect disease genes → intersect → build PPI → top hub genes → dock to top 3–5 hubs → pathway interpretation.

## E. Publication-Oriented Network Toxicology Design
**When**: user wants a stronger mechanism paper with full validation.  
**Logic**: target prediction → disease genes → overlap → PPI + hub identification → GO/KEGG → expression validation → docking → integrated mechanism model → limitations + follow-up suggestions.

## F. Multi-Toxicant Comparative Design
**When**: user provides 2–3 toxicants + one shared disease/phenotype and wants a comparative analysis.  
**Examples**: chlorpyrifos + atrazine + glyphosate + cardiovascular disease · BPA + phthalates + endometriosis · cadmium + lead + CKD.  
**Constraints**: maximum 3 toxicants for Standard tier; 2 toxicants for Lite tier; unlimited for Publication+.  
**Logic**:
1. Run single-toxicant target retrieval (CTD + SwissTargetPrediction) for each toxicant independently
2. Retrieve shared disease targets once (GeneCards + DisGeNET)
3. Compute per-toxicant overlap with disease targets → individual overlap gene lists
4. Generate comparative Venn: all-toxicant shared core · pairwise overlaps · toxicant-exclusive targets
5. Construct unified PPI from the all-toxicant shared core genes (String, confidence ≥ 0.7)
6. Hub gene identification from unified PPI → hub overlap analysis across toxicants
7. GO/KEGG enrichment on shared core + per-toxicant comparison
8. Optional: comparative docking — dock each toxicant to the top shared hub(s); compare binding affinity profiles
9. Mechanism interpretation: shared pathway vulnerability vs. toxicant-specific mechanisms

**Key output additions vs. Pattern A**:
- Comparative Venn figure (3-set or 2-set for each toxicant pair)
- Per-toxicant vs. shared hub gene table
- Comparative docking score table (if docking included)
- Explicit statement: parallel single-toxicant analyses; no interaction/synergy claims between toxicants

**Hard constraints for Pattern F**:
- Never infer synergistic or additive toxicity from target overlap alone
- Always run each toxicant retrieval independently before merging
- If one toxicant returns 0 overlap with disease targets, apply zero-overlap recovery sequence (see `modules.md`) for that toxicant only; do not conflate with other toxicants

```

Example run plan:
1. Confirm the user input, output path, and any required config values.
2. Edit the in-file `CONFIG` block or documented parameters if the script uses fixed settings.
3. Run `python scripts/main.py` with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

## Implementation Details

See `## Workflow` above for related details.

- Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
- Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
- Primary implementation surface: `scripts/__init__.py` with additional helper scripts under `scripts/`.
- Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
- Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

## Quick Check

Use this command to verify that the packaged script entry point can be parsed before deeper execution.

```bash
python -m py_compile scripts/main.py
```

## Audit-Ready Commands

Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths.

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
```

## Workflow

1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work.
2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions.
3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available.
4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items.
5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion.

> `western-blot-quantifier` only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

## Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.

# Waste Disposal Guide

Guide for disposing specific chemical wastes into the correct colored waste containers.

## Quick Check

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
```

## When to Use

- Use this skill when identifying the correct waste container for a specific chemical.
- Use this skill when reviewing waste categories and safety precautions for laboratory chemicals.
- Do not use this skill for emergency spill response, disposal of radioactive materials, or regulated biological waste requiring special handling.

## Workflow

1. Confirm the chemical name or waste type to look up.
2. Validate that the request is for standard laboratory chemical waste disposal guidance.
3. Look up the chemical in the waste category database and return the correct container color and safety notes.
4. **Mixture handling:** If the user provides a mixture (e.g., "chloroform + ethanol"), identify the most hazardous component and assign the container for that component. Emit a note: "Mixed waste containing halogenated solvents must go into the halogenated (orange) container regardless of other components."
5. If the chemical is not found, state that clearly and suggest the closest category based on chemical class.
6. If inputs are incomplete, state which fields are missing and request only the minimum additional information.

## Usage

```text
python scripts/main.py --chemical "chloroform"
python scripts/main.py --chemical "ethanol"
python scripts/main.py --list-categories
python scripts/main.py --safety
```

## Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `--chemical` | string | No | Chemical name to look up |
| `--list-categories` | flag | No | List all waste categories |
| `--safety` | flag | No | Show safety notes for all categories |

## Waste Categories

| Container | Color | Accepts |
|-----------|-------|---------|
| Halogenated | Orange | Chloroform, DCM, halogenated solvents |
| Non-halogenated | Red | Ethanol, acetone, organic solvents |
| Aqueous | Blue | Water-based solutions, buffers |
| Acid | Yellow | Acids (dilute/concentrated) |
| Base | White | Bases, alkali solutions |
| Heavy Metal | Gray | Mercury, lead, cadmium waste |
| Solid | Black | Gloves, paper, solid debris |

**Mixture rule:** When a waste stream contains both halogenated and non-halogenated solvents, use the halogenated (orange) container. When in doubt, consult your institution's EHS office.

## Output

- Correct container color and category for the queried chemical
- Disposal instructions and safety precautions
- Notes on incompatible waste streams

## Scope Boundaries

- This skill covers standard laboratory chemical waste categories; it does not cover radioactive, biological, or controlled substance waste.
- Local regulations may differ; always verify with your institution's EHS office before disposal.
- This skill does not provide emergency spill response guidance.

## Stress-Case Rules

For complex multi-constraint requests, always include these explicit blocks:

1. Assumptions
2. Chemical(s) Queried
3. Disposal Guidance
4. Safety Notes
5. Risks and Manual Checks

## Error Handling

- If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
- If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
- If `scripts/main.py` fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
- Do not fabricate disposal categories or safety classifications for unknown chemicals.

This skill accepts: a chemical name or waste type for container color lookup and disposal guidance.

If the request does not involve standard laboratory chemical waste disposal — for example, asking for emergency spill response, radioactive waste handling, biological waste disposal, or regulatory compliance certification — do not proceed with the workflow. Instead respond:
> "waste-disposal-guide is designed to identify the correct waste container and disposal instructions for standard laboratory chemicals. Your request appears to be outside this scope. Please provide a chemical name, or use a more appropriate tool for specialized waste streams."

## Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.

# POLISH_CHANGELOG — waste-disposal-guide

**Original Score:** 83  
**Polish Date:** 2026-03-19

## Issues Addressed

### P0 / Veto Fixes
- None (no veto failures)

### P1 Fixes
- **Mixture handling undocumented:** Added step 4 to workflow with explicit mixture handling logic. When a user provides a mixed waste stream, the skill now identifies the most hazardous component and assigns the container for that component, with a specific note about halogenated + non-halogenated mixtures.
- **Mixture rule added to Waste Categories:** Added a "Mixture rule" note below the categories table clarifying that halogenated solvents always take precedence.

### P2 Fixes
- None beyond P1 fixes.

### QS-1 (Input Validation)
- Already present and well-formed.

### QS-2 (Progressive Disclosure)
- File is 115 lines — within 300-line limit. No content moved to references/.

### QS-3 (Canonical YAML Frontmatter)
- Already present with all four required fields.

# Volcano Plot Script Generator

A skill for generating publication-ready volcano plots from differential gene expression analysis results.

## When to Use

- Use this skill when the task is to Generate R/Python code for volcano plots from DEG (Differentially Expressed Genes) analysis results. Triggered when user needs visualization of gene expression data, p-value vs fold-change scatter plots, publication-ready figures for bioinformatics analysis.
- Use this skill for data analysis tasks that require explicit assumptions, bounded scope, and a reproducible output format.
- Use this skill when you need a documented fallback path for missing inputs, execution errors, or partial evidence.

## Key Features

- Scope-focused workflow aligned to: Generate R/Python code for volcano plots from DEG (Differentially Expressed Genes) analysis results. Triggered when user needs visualization of gene expression data, p-value vs fold-change scatter plots, publication-ready figures for bioinformatics analysis.
- Packaged executable path(s): `scripts/main.py`.
- Reference material available in `references/` for task-specific guidance.
- Reusable packaged asset(s), including `assets/example_volcano.R`.
- Structured execution path designed to keep outputs consistent and reviewable.

## Dependencies

## Example Usage

See `## Usage` above for related details.

```bash
cd "20260318/scientific-skills/Data Analytics/volcano-plot-script"
python -m py_compile scripts/main.py
python scripts/main.py --help
```

Example run plan:
1. Confirm the user input, output path, and any required config values.
2. Edit the in-file `CONFIG` block or documented parameters if the script uses fixed settings.
3. Run `python scripts/main.py` with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

## Implementation Details

See `## Workflow` above for related details.

- Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
- Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
- Primary implementation surface: `scripts/main.py`.
- Reference guidance: `references/` contains supporting rules, prompts, or checklists.
- Packaged assets: reusable files are available under `assets/`.
- Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
- Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

## Quick Check

Use this command to verify that the packaged script entry point can be parsed before deeper execution.

```bash
python -m py_compile scripts/main.py
```

## Audit-Ready Commands

Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths.

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
python scripts/main.py --input "Audit validation sample with explicit symptoms, history, assessment, and next-step plan."
```

## Workflow

1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work.
2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions.
3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available.
4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items.
5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion.

## Overview

Volcano plots visualize the relationship between statistical significance (p-values) and magnitude of change (fold changes) in gene expression data. This skill generates customizable R or Python scripts for creating high-quality figures suitable for publications.

- Log2 fold change values
- Adjusted or raw p-values
- Optional: gene annotations, pathways

## Output

- Publication-ready volcano plot (PNG/PDF/SVG)
- Customizable R or Python script
- Optional: labeled significant gene lists

## Usage

```python

# Example: Run the volcano plot generator
python scripts/main.py --input deg_results.csv --output volcano_plot.png
```

| `--pvalue-col` | Column name for p-value | padj |
| `--gene-col` | Column name for gene IDs | gene |
| `--log2fc-thresh` | Log2 FC threshold for significance | 1.0 |
| `--pvalue-thresh` | P-value threshold | 0.05 |
| `--label-genes` | File with genes to label | None |
| `--top-n` | Label top N significant genes | 10 |
| `--color-up` | Color for upregulated genes | #E74C3C |
| `--color-down` | Color for downregulated genes | #3498DB |
| `--color-ns` | Color for non-significant genes | #95A5A6 |

## Technical Difficulty

**Medium** - Requires understanding of:
- DEG analysis concepts (fold change, p-values, FDR)
- Data visualization principles
- Matplotlib/ggplot2 plotting libraries

### Python
- pandas
- matplotlib
- seaborn
- numpy

### R
- ggplot2
- dplyr
- ggrepel (for label positioning)

2. **Custom Thresholds**: Adjust log2FC and p-value thresholds → Correct gene classification
3. **Gene Labeling**: Specify genes to label → Labels appear correctly
4. **Large Dataset**: Input 20,000+ genes → Performance remains acceptable
5. **Malformed Data**: Input with missing values → Graceful error handling

## Lifecycle Status

- **Current Stage**: Draft
- **Next Review Date**: 2026-03-06
- **Known Issues**: None
- **Planned Improvements**:
  - Add interactive plot option (Plotly)
  - Support for multiple comparison groups
  - Integration with pathway enrichment tools

## Output Requirements

Every final response should make these items explicit when they are relevant:

- Objective or requested deliverable
- Inputs used and assumptions introduced
- Workflow or decision path
- Core result, recommendation, or artifact
- Constraints, risks, caveats, or validation needs
- Unresolved items and next-step checks

## Error Handling

- If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
- If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
- If `scripts/main.py` fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
- Do not fabricate files, citations, data, search results, or execution outcomes.

## Input Validation

This skill accepts requests that match the documented purpose of `volcano-plot-script` and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

> `volcano-plot-script` only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

## Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.

# Volcano Plot Best Practices

## Overview

Volcano plots are scatter plots that visualize differential gene expression results, showing the relationship between statistical significance and magnitude of change.

## Key Elements

### X-axis: Log2 Fold Change
- Represents the magnitude of change in gene expression
- Positive values = upregulation
- Negative values = downregulation
- Log2 scale: +1 = 2x increase, +2 = 4x increase, etc.

### Y-axis: -Log10 P-value
- Represents statistical significance
- Higher values = more significant
- Common thresholds: 0.05 (y=1.3), 0.01 (y=2), 0.001 (y=3)

## Interpretation

1. **Top-right quadrant**: Highly significant upregulated genes
2. **Top-left quadrant**: Highly significant downregulated genes
3. **Center-bottom**: Genes with no significant change
4. **Far left/right (low)**: Large fold changes but not statistically significant

## Best Practices

### Threshold Selection
- **Log2FC threshold**: Typically 0.5-1.0 (1.5x to 2x change)
- **P-value threshold**: Usually 0.05 (FDR-corrected recommended)

### Color Schemes
- Use colorblind-friendly palettes
- Clear distinction between up/down/non-significant
- Avoid red-green combinations (colorblindness)

### Labeling
- Label only key genes of interest
- Avoid cluttering with too many labels
- Use repelling algorithms for label placement

### Publication Quality
- High DPI (300+) for print
- Clear axis labels and titles
- Include sample size in caption
- Provide threshold values in methods

## Common Variations

1. **Enhanced volcano plots**: Add gene labels, annotations

# Volcano Plot Labeler (ID: 148)

Automatically identify and label the Top 10 most significant genes in volcano plots using a repulsion algorithm to prevent label overlap.

## When to Use

- Use this skill when the task needs Automatically label top significant genes in volcano plots with repulsion.
- Use this skill for data analysis tasks that require explicit assumptions, bounded scope, and a reproducible output format.
- Use this skill when you need a documented fallback path for missing inputs, execution errors, or partial evidence.

## Key Features

See `## Features` above for related details.

- Scope-focused workflow aligned to: Analyze data with `volcano-plot-labeler` using a reproducible workflow, explicit validation, and structured outputs for review-ready interpretation.
- Packaged executable path(s): `scripts/main.py`.
- Reference material available in `references/` for task-specific guidance.
- Structured execution path designed to keep outputs consistent and reviewable.

## Dependencies

See `## Prerequisites` above for related details.

- `Python`: `3.10+`. Repository baseline for current packaged skills.
- `matplotlib`: `unspecified`. Declared in `requirements.txt`.
- `numpy`: `unspecified`. Declared in `requirements.txt`.
- `pandas`: `unspecified`. Declared in `requirements.txt`.

## Example Usage

See `## Usage` above for related details.

```bash
cd "20260318/scientific-skills/Data Analytics/volcano-plot-labeler"
python -m py_compile scripts/main.py
python scripts/main.py --help
```

Example run plan:
1. Confirm the user input, output path, and any required config values.
2. Edit the in-file `CONFIG` block or documented parameters if the script uses fixed settings.
3. Run `python scripts/main.py` with the validated inputs.
4. Review the generated output and return the final artifact with any assumptions called out.

## Implementation Details

See `## Workflow` above for related details.

- Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
- Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
- Primary implementation surface: `scripts/main.py`.
- Reference guidance: `references/` contains supporting rules, prompts, or checklists.
- Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
- Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

## Quick Check

Use this command to verify that the packaged script entry point can be parsed before deeper execution.

```bash
python -m py_compile scripts/main.py
```

## Audit-Ready Commands

Use these concrete commands for validation. They are intentionally self-contained and avoid placeholder paths.

```bash
python -m py_compile scripts/main.py
python scripts/main.py --help
python scripts/main.py --input "Audit validation sample with explicit symptoms, history, assessment, and next-step plan."
```

## Workflow

1. Confirm the user objective, required inputs, and non-negotiable constraints before doing detailed work.
2. Validate that the request matches the documented scope and stop early if the task would require unsupported assumptions.
3. Use the packaged script path or the documented reasoning path with only the inputs that are actually available.
4. Return a structured result that separates assumptions, deliverables, risks, and unresolved items.
5. If execution fails or inputs are incomplete, switch to the fallback path and state exactly what blocked full completion.

## Features

- **Smart Gene Selection**: Automatically identifies the top 10 most significant genes based on p-value and fold change
- **Repulsion Algorithm**: Uses force-directed positioning to prevent text label overlap
- **Customizable**: Configurable thresholds, label styling, and positioning options
- **Multiple Output Formats**: PNG, PDF, SVG support

## Installation

```text
pip install pandas matplotlib numpy scipy
```

## Usage

### Basic Usage

```python
from volcano_plot_labeler import label_volcano_plot
import pandas as pd

# Load your data
df = pd.read_csv('differential_expression_results.csv')

# Generate labeled volcano plot
fig = label_volcano_plot(
    df,
    log2fc_col='log2FoldChange',
    pvalue_col='padj',
    gene_col='gene_name',
    top_n=10
)
fig.savefig('volcano_plot_labeled.png', dpi=300, bbox_inches='tight')
```

### Advanced Usage

```python
from volcano_plot_labeler import label_volcano_plot

fig = label_volcano_plot(
    df,
    log2fc_col='log2FoldChange',
    pvalue_col='padj',
    gene_col='gene_name',
    top_n=10,
    pvalue_threshold=0.05,
    log2fc_threshold=1.0,
    figsize=(12, 10),
    repulsion_iterations=100,
    repulsion_force=0.05,
    label_fontsize=10,
    label_color='black',
    arrow_color='gray',
    save_path='output.png'
)
```

### Command Line Usage

```text
python scripts/main.py \
    --input data/deseq2_results.csv \
    --output volcano_labeled.png \
    --log2fc-col log2FoldChange \
    --pvalue-col padj \
    --gene-col gene_name \
    --top-n 10
```

## Input Format

Expected CSV/TSV columns:
- `log2FoldChange`: Log2 fold change values
- `padj` or `pvalue`: Adjusted p-values or raw p-values
- `gene_name`: Gene identifiers

## Algorithm

### Significance Calculation
1. Calculate `-log10(pvalue)` for all genes
2. Rank genes by combined score: `|log2FC| * -log10(pvalue)`
3. Select top N genes with highest significance

### Repulsion Algorithm
1. **Initial Placement**: Place labels at gene coordinates
2. **Force Calculation**: 
   - Repulsive force between overlapping labels
   - Spring force pulling label toward its gene point
   - Boundary forces to keep labels within plot area
3. **Iterative Optimization**: Update positions for N iterations until convergence
4. **Arrow Drawing**: Draw connecting lines from labels to gene points

## Parameters

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `df` | DataFrame | - | Input data |
| `log2fc_col` | str | 'log2FoldChange' | Column name for log2 fold change |
| `pvalue_col` | str | 'padj' | Column name for p-value |
| `gene_col` | str | 'gene_name' | Column name for gene names |

| `label_fontsize` | int | 10 | Font size for labels |
| `figsize` | tuple | (10, 10) | Figure size |

## Output

- Labeled volcano plot with:
  - Color-coded points (up/down/not significant)
  - Top 10 gene labels with leader lines
  - No overlapping text labels

## Lifecycle Status

- **Current Stage**: Draft
- **Next Review Date**: 2026-03-06
- **Known Issues**: None
- **Planned Improvements**: 
  - Performance optimization
  - Additional feature support

## Output Requirements

Every final response should make these items explicit when they are relevant:

- Objective or requested deliverable
- Inputs used and assumptions introduced
- Workflow or decision path
- Core result, recommendation, or artifact
- Constraints, risks, caveats, or validation needs
- Unresolved items and next-step checks

## Error Handling

- If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
- If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
- If `scripts/main.py` fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
- Do not fabricate files, citations, data, search results, or execution outcomes.

## Input Validation

This skill accepts requests that match the documented purpose of `volcano-plot-labeler` and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

> `volcano-plot-labeler` only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

## Response Template

Use the following fixed structure for non-trivial requests:

1. Objective
2. Inputs Received
3. Assumptions
4. Workflow
5. Deliverable
6. Risks and Limits
7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.

## Inputs to Collect

- Required inputs: the user goal, the primary data or source file, and the requested output format.
- Optional inputs: output directory, formatting preferences, and validation constraints.
- If a required input is unavailable, return a short clarification request before continuing.

## Output Contract

- Return a short summary, the main deliverables, and any assumptions that materially affect interpretation.
- If execution is partial, label what succeeded, what failed, and the next safe recovery step.
- Keep the final answer within the documented scope of the skill.

## Validation and Safety Rules

- Validate identifiers, file paths, and user-provided parameters before execution.
- Do not fabricate results, metrics, citations, or downstream conclusions.
- Use safe fallback behavior when dependencies, credentials, or required inputs are missing.
- Surface any execution failure with a concise diagnosis and recovery path.

FILE:references/runtime_checklist.md
# Runtime Checklist

- Category: `Data Analysis`
- Validate the user goal, required inputs, and output format before taking action.
- Ask a targeted clarification question when a required input is missing.
- Keep the response scoped to the documented workflow and state assumptions explicitly.
- Run a non-destructive smoke check before any file-dependent or data-dependent command.
- Recommended smoke check: `python -m py_compile scripts/main.py`
- If execution fails, stop and return a concise recovery path instead of fabricating results.
