# Trend

Content creation and management toolkit. Draft posts, edit content, optimize for engagement, schedule publications, generate hashtags, write hooks and CTAs, rewrite text, translate content, adjust tone, craft headlines, and build outlines. All entries are timestamped and stored locally for full traceability.

## Commands

### Content Creation

| Command | Description |
|---------|-------------|
| `trend draft [input]` | Draft new content (no args = show recent drafts) |
| `trend edit [input]` | Edit/refine content (no args = show recent edits) |
| `trend rewrite [input]` | Rewrite existing content (no args = show recent rewrites) |
| `trend headline [input]` | Craft headlines (no args = show recent headlines) |
| `trend outline [input]` | Build content outlines (no args = show recent outlines) |

### Content Optimization

| Command | Description |
|---------|-------------|
| `trend optimize [input]` | Optimize content for engagement (no args = show recent) |
| `trend hashtags [input]` | Generate hashtags (no args = show recent) |
| `trend hooks [input]` | Write attention-grabbing hooks (no args = show recent) |
| `trend cta [input]` | Create calls-to-action (no args = show recent) |
| `trend tone [input]` | Adjust content tone (no args = show recent) |

### Publishing

| Command | Description |
|---------|-------------|
| `trend schedule [input]` | Schedule content for publication (no args = show recent) |
| `trend translate [input]` | Translate content (no args = show recent translations) |

### Data & Reporting

| Command | Description |
|---------|-------------|
| `trend stats` | Summary statistics across all entry types |
| `trend export <fmt>` | Export all data (json, csv, or txt) |
| `trend search <term>` | Search across all entries |
| `trend recent` | Show last 20 activity log entries |
| `trend status` | Health check: version, entry count, disk usage, last activity |

### Utility

| Command | Description |
|---------|-------------|
| `trend help` | Show help with all commands |
| `trend version` | Show version number |

## Data Storage

All data is stored locally at `~/.local/share/trend/` by default:

- `draft.log`, `edit.log`, `optimize.log`, etc. — One log file per command type, entries are `timestamp|input` format
- `history.log` — Unified activity history with timestamps for every command run
- `export.json`, `export.csv`, `export.txt` — Generated export files

Each command supports two modes:
- **With arguments:** Saves the input with a timestamp and confirms
- **Without arguments:** Shows the 20 most recent entries for that command type

## Requirements

- bash 4+
- Standard UNIX utilities (`date`, `wc`, `du`, `grep`, `tail`, `head`, `sed`, `cut`)
- No external dependencies or API keys required

## When to Use

1. **Content drafting workflow** — Use `draft` to capture ideas, `outline` to structure them, `headline` to title them, then `edit` to refine
2. **Social media optimization** — Run `hashtags` for tags, `hooks` for attention-grabbing openers, `cta` for calls-to-action, and `tone` to match platform voice
3. **Content scheduling** — Use `schedule` to log publication timelines and `translate` to prepare multi-language versions
4. **Content audit** — Run `stats` to see activity across all content types, `search` to find specific entries, and `recent` to review the latest work
5. **Data export and backup** — Use `export json` for structured data, `export csv` for spreadsheet import, or `export txt` for readable dumps

## Examples

```bash
# Draft a new blog post idea
trend draft "10 tips for better remote work productivity"

# View all recent drafts
trend draft

# Create an outline for the post
trend outline "Intro, 10 tips with examples, conclusion with CTA"

# Craft a headline
trend headline "Remote Work Productivity: 10 Tips That Actually Work"

# Generate hashtags for social media
trend hashtags "#remotework #productivity #wfh #tipsandtricks"

# Write a hook for the post
trend hooks "Most remote workers waste 3 hours a day. Here's how to fix that."

# Create a call-to-action
trend cta "Download our free remote work checklist"

# Optimize the content
trend optimize "Added power words, shortened paragraphs, added bullet points"

# Adjust tone for LinkedIn
trend tone "Professional but approachable, data-driven"

# Schedule for publication
trend schedule "Publish Monday 9am EST on blog, noon on LinkedIn"

# Translate to another language
trend translate "Spanish version for LATAM audience"

# Rewrite an existing section
trend rewrite "Simplified the introduction, removed jargon"

# Edit the final draft
trend edit "Final proofread, fixed typos, added links"

# Check overall stats
trend stats

# Export all data as JSON
trend export json

# Search for a specific topic
trend search "productivity"

# View recent activity
trend recent

# Health check
trend status
```

## Tips

- Every command with input is automatically timestamped and logged — nothing is lost
- Run commands without arguments to review your recent entries (shows last 20)
- Use `stats` to see entry counts per command type for a bird's-eye view
- Export supports three formats: `json` (structured), `csv` (spreadsheets), `txt` (human-readable)
- All log files are plain text and can be edited or grepped directly

3. **Resilient Pattern**: For fault-tolerant implementations

## Best Practices
- Follow the principle of least privilege
- Use version control for all configurations
- Implement comprehensive logging
- Test changes in staging before production
- Document all custom configurations

## Anti-Patterns to Avoid
- Hardcoding credentials or configuration
- Skipping validation and error handling
- Ignoring monitoring and alerting
- Making changes without documentation
- Over-engineering simple solutions

cmd_debugging() {
    cat << 'EOF'
# Hashtag — Debugging Guide

## Common Errors
1. **Connection refused**: Check service status and network
2. **Permission denied**: Verify credentials and access rights
3. **Timeout**: Check network, increase limits, optimize queries
4. **Invalid input**: Validate data format and encoding

## Debugging Tools
- Built-in logging and diagnostics
- Network analysis tools (tcpdump, wireshark)
- System monitoring (top, htop, iostat)
- Application-specific debug modes

## Debug Workflow
1. Reproduce the issue consistently
2. Check logs for error messages
3. Isolate the failing component
4. Test with minimal configuration
5. Apply fix and verify

# Lint

Lint is a developer-focused toolkit for recording and tracking code quality operations from the terminal. It provides 13 core action commands for managing checks, validations, formatting, linting, code generation, conversions, templates, diffs, previews, fixes, reports, and explanations — all with timestamped local logging for full traceability. Additional utility commands let you view statistics, export data, search history, and monitor health status.

## Commands

### Core Action Commands

Each action command works in two modes: run without arguments to view the 20 most recent entries, or pass input text to record a new timestamped entry.

| Command | Description |
|---------|-------------|
| `lint check <input>` | Record a syntax/code check entry |
| `lint validate <input>` | Record a validation result |
| `lint generate <input>` | Record a code generation action |
| `lint format <input>` | Record a formatting operation |
| `lint lint <input>` | Record a linting pass |
| `lint explain <input>` | Record an explanation or annotation |
| `lint convert <input>` | Record a conversion operation |
| `lint template <input>` | Record a template action |
| `lint diff <input>` | Record a diff comparison |
| `lint preview <input>` | Record a preview action |
| `lint fix <input>` | Record an auto-fix action |
| `lint report <input>` | Record a report generation |

### Utility Commands

| Command | Description |
|---------|-------------|
| `lint stats` | Show summary statistics — entry counts per category, total entries, data size, and earliest activity timestamp |
| `lint export <fmt>` | Export all data to JSON, CSV, or TXT format. Output file saved to `~/.local/share/lint/export.<fmt>` |
| `lint search <term>` | Full-text search across all log files (case-insensitive) |
| `lint recent` | Show the 20 most recent entries from the history log |
| `lint status` | Health check — version, data directory, total entries, disk usage, last activity |
| `lint help` | Show help with all available commands |
| `lint version` | Print version string (`lint v2.0.0`) |

## Data Storage

All data is stored locally in `~/.local/share/lint/`. Each action command writes to its own log file (e.g., `check.log`, `validate.log`, `fix.log`). A unified `history.log` records every action with timestamps. No external services, databases, or network connections are used.

**Directory structure:**
```
~/.local/share/lint/
├── check.log        # Check entries
├── validate.log     # Validation entries
├── generate.log     # Generation entries
├── format.log       # Formatting entries
├── lint.log         # Lint pass entries
├── explain.log      # Explanation entries
├── convert.log      # Conversion entries
├── template.log     # Template entries
├── diff.log         # Diff entries
├── preview.log      # Preview entries
├── fix.log          # Fix entries
├── report.log       # Report entries
├── history.log      # Unified activity log
└── export.*         # Export output files
```

## Requirements

- Bash (with `set -euo pipefail`)
- Standard Unix utilities: `date`, `wc`, `du`, `head`, `tail`, `grep`, `basename`, `cut`
- No external dependencies or API keys required

## When to Use

1. **Tracking linting sessions** — Record which files you linted, what issues you found, and what fixes you applied, all with timestamps for audit trails.
2. **Code review workflows** — Log check and validate results during PR reviews so you can refer back to what was inspected and when.
3. **Template and diff management** — Keep a running record of template operations and diff comparisons across project iterations.
4. **Exporting quality reports** — Use `lint export json` to generate machine-readable reports of all recorded lint activity for CI dashboards or team reviews.
5. **Searching past actions** — Quickly find previous lint results, fixes, or explanations with `lint search <term>` across all categories.

## Examples

```bash
# Record a check on a Python file
lint check "src/main.py — 3 unused imports found"

# Record a fix applied
lint fix "Removed unused imports in src/main.py"

# View recent formatting actions
lint format

# Search for all entries mentioning "import"
lint search import

# Export everything to JSON
lint export json

# View overall statistics
lint stats

# Health check
lint status
```

# vision

Image processing toolkit powered by ImageMagick. 

## Quick Start / 快速开始
Just ask your AI assistant: / 直接告诉 AI 助手：
- "Resize photo.jpg to 800px width" (帮我把 photo.jpg 缩小到 800 宽)
- "Convert this PNG to WebP format" (把这张 PNG 图片转换成 WebP 格式)
- "Add watermark: © 2025 BytesAgain" (给这张图加个水印)

## Commands

### resize
Resize an image.
```bash
bash scripts/script.sh resize --input photo.jpg --width 800
bash scripts/script.sh resize --input photo.jpg --percent 50
```

### convert
Change image formats.
```bash
bash scripts/script.sh convert --input photo.png --to webp
bash scripts/script.sh convert --input photo.jpg --to png
```

### optimize
Compress file size without losing quality.
```bash
bash scripts/script.sh optimize --input photo.jpg --quality 80
```

### watermark
Add text watermark to images.
```bash
bash scripts/script.sh watermark --input photo.jpg --text "© 2025" --position southeast
```

## Requirements
- bash 4+
- ImageMagick (convert, identify)

# NLP — Natural Language Processing Toolbox

A pure-bash NLP toolkit for text analysis. Tokenize text, analyze sentiment, extract named entities, summarize documents, compute text similarity, and classify text into categories — all from the command line with no external dependencies.

## Commands

### tokenize

Split text into words and sentences. Returns word count, sentence count, individual tokens, and the top 10 most frequent words.

```bash
bash scripts/script.sh tokenize --input "The quick brown fox jumps over the lazy dog."
bash scripts/script.sh tokenize --file document.txt
bash scripts/script.sh tokenize --file document.txt --json
cat essay.txt | bash scripts/script.sh tokenize
```

### sentiment

Analyze text sentiment using built-in positive/negative word lists. Returns polarity (positive/negative/neutral), a score from -1.0 to 1.0, confidence level, and matched word counts. Handles negators (e.g., "not good" flips sentiment) and intensifiers.

```bash
bash scripts/script.sh sentiment --input "I absolutely love this product! It's amazing."
bash scripts/script.sh sentiment --file reviews.txt
bash scripts/script.sh sentiment --input "This was not good at all" --json
```

### extract

Extract named entities from text: names/people (consecutive capitalized words), organizations (with suffixes like Inc, Corp, Ltd, LLC), dates (multiple formats), numbers with units, email addresses, and URLs.

```bash
bash scripts/script.sh extract --input "John Smith works at Google Inc in Mountain View since 2020-01-15. Contact [email protected]"
bash scripts/script.sh extract --file article.txt --json
```

### summarize

Generate a summary by extracting the most important sentences. Scores sentences by word frequency with position bonuses (first/last sentences weighted higher). Control output length with `--sentences N` or `--ratio 0.3`.

```bash
bash scripts/script.sh summarize --file long_article.txt --sentences 3
bash scripts/script.sh summarize --input "Long text here..." --ratio 0.3
cat report.txt | bash scripts/script.sh summarize --sentences 5
bash scripts/script.sh summarize --file paper.txt --json
```

### similarity

Compute similarity between two texts using Jaccard index (word set overlap) and cosine similarity (word frequency vectors). Returns an overall score (average of both), shared word count, and unique word count. Scale: 0.0 = completely different, 1.0 = identical.

```bash
bash scripts/script.sh similarity --text1 "The cat sat on the mat" --text2 "A cat was sitting on a mat"
bash scripts/script.sh similarity --file1 doc1.txt --file2 doc2.txt
bash scripts/script.sh similarity --text1 "hello world" --text2 "hello world" --json
```

### classify

Classify text into user-provided categories using keyword matching. Has built-in keyword dictionaries for common categories: finance, sports, tech, politics, science, health, positive, negative, neutral. Returns the predicted category with confidence scores and hit counts for each category.

```bash
bash scripts/script.sh classify --input "The stock market rallied today on strong earnings" --categories "finance,sports,tech,politics"
bash scripts/script.sh classify --file article.txt --categories "positive,negative,neutral"
bash scripts/script.sh classify --input "New treatment shows promise in clinical trials" --categories "health,science,tech" --json
```

## Global Flags

| Flag | Description |
|------|-------------|
| `--json` | Output results in JSON format instead of plain text |

## Input Methods

All commands accept input via three methods:

1. **`--input "text"`** — inline text string
2. **`--file path.txt`** — read from a file
3. **Pipe via stdin** — `cat file.txt | bash scripts/script.sh <command>`

## Data Storage

This tool is stateless — it does not write to disk. All processing happens in memory and output goes to stdout/stderr.

## Requirements

- Bash 4+ (uses associative arrays)
- `grep` with `-P` (Perl regex) for entity extraction
- `awk` for floating-point calculations
- No Python, no external NLP libraries — pure shell

## When to Use

1. **Quick text analysis** — tokenize a document to get word counts and frequency distributions without leaving the terminal
2. **Sentiment checking** — analyze customer reviews, social media posts, or feedback files for positive/negative polarity
3. **Entity extraction** — pull out names, organizations, dates, emails, and URLs from unstructured text
4. **Document summarization** — distill long articles or reports into key sentences at a chosen ratio
5. **Text comparison** — measure how similar two documents are using Jaccard and cosine metrics for deduplication or plagiarism detection

## Examples

```bash
# Tokenize and get word frequency from a file
bash scripts/script.sh tokenize --file essay.txt

# Sentiment analysis with JSON output
bash scripts/script.sh sentiment --input "The movie was terrible and boring" --json

# Extract entities from an article
bash scripts/script.sh extract --file news_article.txt

# Summarize a long document to 5 key sentences
bash scripts/script.sh summarize --file report.txt --sentences 5

# Compare two documents for similarity
bash scripts/script.sh similarity --file1 original.txt --file2 revised.txt --json

# Classify text into categories
bash scripts/script.sh classify --input "Scientists discovered a new particle at CERN" --categories "science,tech,politics,sports"
```

## Output

Plain text by default with clear section headers. Use `--json` flag for machine-readable JSON output suitable for piping into `jq` or other tools. Sentiment returns polarity and score. Extract returns categorized entity lists. Similarity returns a 0.0–1.0 score.

# gpt

GPT API calling assistant. Build chat completion requests, generate embedding payloads, prepare fine-tuning data, estimate costs, batch requests, and convert between formats.

## Commands

### chat

Build a chat completion request JSON payload from messages.

```bash
bash scripts/script.sh chat --system "You are a translator" --user "Translate: hello"
bash scripts/script.sh chat --system "Helper" --user "Hi" --model gpt-4o --temperature 0.7
```

### embed

Generate an embedding API request payload.

```bash
bash scripts/script.sh embed --input "Text to embed"
bash scripts/script.sh embed --file texts.txt --model text-embedding-3-small
```

### finetune

Prepare and validate fine-tuning JSONL data from source files.

```bash
bash scripts/script.sh finetune --input pairs.csv --output training.jsonl
bash scripts/script.sh finetune --validate training.jsonl
```

### cost

Estimate API costs based on token count and model pricing.

```bash
bash scripts/script.sh cost --tokens 5000 --model gpt-4o
bash scripts/script.sh cost --file input.txt --model gpt-4-turbo
```

### batch

Generate multiple API request payloads from a list of inputs.

```bash
bash scripts/script.sh batch --file prompts.txt --model gpt-4o --output batch_requests.jsonl
```

### convert

Convert between JSONL and CSV data formats.

```bash
bash scripts/script.sh convert --input data.csv --to jsonl --output data.jsonl
bash scripts/script.sh convert --input data.jsonl --to csv --output data.csv
```

## Output

All commands output JSON request bodies or JSONL to stdout by default. Use `--output` to write to a file. Cost estimates print a breakdown table with per-model pricing.


## Requirements
- bash 4+

# Leads — Sales Lead CRM

Manage sales leads through their lifecycle: add, score, follow up, convert, and report on your pipeline.

## Commands

### add — Add a new lead

```bash
bash scripts/script.sh add "<name>" "<email>" "<company>" "[source]"
```

Creates a new lead with status `new`. Source defaults to `direct`.

### list — View leads

```bash
bash scripts/script.sh list [status] [--sort score|date]
```

Lists all leads, optionally filtered by status (`new`, `contacted`, `qualified`, `converted`, `lost`). Sort by score or date.

### score — Score a lead

```bash
bash scripts/script.sh score "<lead_id>" <points> "[reason]"
```

Assigns or adds score points to a lead. Score range: 0–100. Higher = more likely to convert.

### follow-up — Set follow-up reminder

```bash
bash scripts/script.sh follow-up "<lead_id>" "<YYYY-MM-DD>" "<note>"
```

Schedules a follow-up action for a lead on the specified date with a note.

### convert — Mark lead as converted

```bash
bash scripts/script.sh convert "<lead_id>" "[deal_value]"
```

Changes lead status to `converted` and optionally records deal value.

### pipeline — Sales funnel report

```bash
bash scripts/script.sh pipeline [YYYY-MM]
```

Shows a funnel breakdown of leads by status with counts and conversion rates. Defaults to current month.

## Output

All commands print plain text to stdout. Data is stored in `~/.leads/leads.json`.


## Requirements
- bash 4+
- python3 (standard library only)

# Orders Skill

Create, track, update, cancel, and report on orders.

## Commands

### create

Create a new order.

```bash
bash scripts/script.sh create <customer> <item> <quantity> <unit_price> [--note <text>]
```

### list

List all orders or filter by status.

```bash
bash scripts/script.sh list [--status pending|shipped|delivered|cancelled] [--format table|json|csv]
```

### status

Query the status of a specific order.

```bash
bash scripts/script.sh status <order_id>
```

### update

Update an existing order (status, quantity, or note).

```bash
bash scripts/script.sh update <order_id> [--status <new_status>] [--quantity <num>] [--note <text>]
```

### cancel

Cancel an order by ID.

```bash
bash scripts/script.sh cancel <order_id> [--reason <text>]
```

### report

Generate a summary report of all orders.

```bash
bash scripts/script.sh report [--period today|week|month|all] [--format table|json]
```

## Output

All commands print to stdout. Order data is stored in `~/.orders/orders.json`. Order IDs are auto-generated. Use `--format json` for machine-readable output where supported.


## Requirements
- bash 4+
- python3 (standard library only)

# RegexPal

A real regex tester and toolkit for the terminal. Test patterns against text, find matches in files with highlighted output, perform replacements, extract capturing groups, and get human-readable explanations of regex syntax.

## Commands

| Command | Description |
|---------|-------------|
| `regexpal test <pattern> <text>` | Test if a regex matches text — reports full match, partial match, groups, and named groups |
| `regexpal match <pattern> <file>` | Find all matches in a file — highlights matches in red, shows line numbers and match count |
| `regexpal replace <pattern> <replacement> <file>` | Replace all matches in a file and output to stdout. Supports backreferences (`\1`, `\2`) |
| `regexpal extract <pattern> <file>` | Extract capturing groups from all matches in a file — shows each group value per match |
| `regexpal explain <pattern>` | Break down a regex pattern — lists character classes, groups, tokens, and quantifiers |

## Requirements

- `python3` (uses `re` stdlib module)

## Examples

```bash
# Test a pattern
regexpal test '^\d{3}-\d{4}$' '123-4567'

# Find emails in a file
regexpal match '\w+@[\w.-]+' contacts.txt

# Replace version numbers
regexpal replace 'v(\d+)\.(\d+)' 'v\1.$((\\2+1))' changelog.md

# Extract domain parts from emails
regexpal extract '(\w+)@(\w+\.\w+)' emails.txt

# Understand a complex pattern
regexpal explain '(?<=@)[\w.-]+'
```

# CronJob

A comprehensive sysops toolkit for scanning, monitoring, reporting, and maintaining scheduled job operations. CronJob provides 18+ commands for tracking job events, performing health checks, managing backups, benchmarking performance, and exporting operational data in multiple formats.

## Commands

| Command | Description |
|---------|-------------|
| `cronjob scan <input>` | Record a scan entry — run without args to view recent scan entries |
| `cronjob monitor <input>` | Record a monitoring observation — run without args to view recent entries |
| `cronjob report <input>` | Log a report entry — run without args to view recent reports |
| `cronjob alert <input>` | Record an alert — run without args to view recent alerts |
| `cronjob top <input>` | Log a top-level event — run without args to view recent entries |
| `cronjob usage <input>` | Track usage data — run without args to view recent usage entries |
| `cronjob check <input>` | Record a check result — run without args to view recent checks |
| `cronjob fix <input>` | Log a fix action — run without args to view recent fixes |
| `cronjob cleanup <input>` | Record a cleanup operation — run without args to view recent cleanups |
| `cronjob backup <input>` | Log a backup event — run without args to view recent backups |
| `cronjob restore <input>` | Record a restore operation — run without args to view recent restores |
| `cronjob log <input>` | Add a general log entry — run without args to view recent log entries |
| `cronjob benchmark <input>` | Record a benchmark result — run without args to view recent benchmarks |
| `cronjob compare <input>` | Log a comparison — run without args to view recent comparisons |
| `cronjob stats` | Display summary statistics across all log categories |
| `cronjob export <fmt>` | Export all data to a file (formats: `json`, `csv`, `txt`) |
| `cronjob search <term>` | Search across all log files for a keyword |
| `cronjob recent` | Show the 20 most recent activity entries from the history log |
| `cronjob status` | Health check — shows version, data directory, entry count, disk usage |
| `cronjob help` | Display available commands and usage information |
| `cronjob version` | Print current version (v2.0.0) |

Each data command (scan, monitor, report, etc.) works in two modes:
- **With arguments**: Records the input with a timestamp into its dedicated log file
- **Without arguments**: Displays the 20 most recent entries from that category

## Data Storage

All data is stored locally in plain-text log files:

- **Location**: `~/.local/share/cronjob/`
- **Format**: Each entry is saved as `YYYY-MM-DD HH:MM|<value>` in per-category `.log` files
- **History**: All operations are additionally logged to `history.log` with timestamps
- **Export**: The `export` command can generate JSON, CSV, or TXT files from all log data
- **No cloud sync** — everything stays on your machine

## Requirements

- Bash 4.0+ (uses `set -euo pipefail`)
- Standard Unix utilities: `date`, `wc`, `du`, `head`, `tail`, `grep`, `basename`, `cat`
- No external dependencies, no API keys, no network access required
- Works on Linux and macOS

## When to Use

1. **Cron job monitoring** — Track the execution status of scheduled jobs, log failures, and set up alerts for review
2. **Job audit trail** — Record scan, check, and report entries to maintain a complete history of job operations
3. **Backup & restore logging** — Log backup and restore events with timestamps so you always know what happened and when
4. **Performance benchmarking** — Record benchmark results for scheduled tasks and compare them over time to spot regressions
5. **Operational data export** — Export all collected logs in JSON, CSV, or TXT format for dashboards, compliance, or further analysis

## Examples

```bash
# Record a scan of cron job health
cronjob scan "all 12 scheduled jobs ran successfully today"

# Log a monitoring observation
cronjob monitor "backup-job took 45min, 3x longer than usual"

# Record an alert for a failed job
cronjob alert "daily-report cron failed at 03:00 — exit code 1"

# Log a fix action taken
cronjob fix "increased timeout for backup-job from 30m to 90m"

# View summary statistics across all categories
cronjob stats

# Export all data to CSV for spreadsheet analysis
cronjob export csv

# Search for entries related to a specific job
cronjob search "backup-job"

# Quick health check
cronjob status

# View the 20 most recent activity entries
cronjob recent
```

## Configuration

Set `CRONJOB_DIR` to change the data directory. Default: `~/.local/share/cronjob/`

## Design Patterns
1. **Standard Pattern**: The most common approach for fakerjs
2. **Scalable Pattern**: For high-volume or distributed scenarios
3. **Resilient Pattern**: For fault-tolerant implementations

## Best Practices
- Follow the principle of least privilege
- Use version control for all configurations
- Implement comprehensive logging
- Test changes in staging before production
- Document all custom configurations

## Anti-Patterns to Avoid
- Hardcoding credentials or configuration
- Skipping validation and error handling
- Ignoring monitoring and alerting
- Making changes without documentation
- Over-engineering simple solutions
EOF
}

cmd_debugging() {
    cat << 'EOF'
# Fakerjs — Debugging Guide

## Common Errors
1. **Connection refused**: Check service status and network
2. **Permission denied**: Verify credentials and access rights
3. **Timeout**: Check network, increase limits, optimize queries
4. **Invalid input**: Validate data format and encoding

## Debugging Tools
- Built-in logging and diagnostics
- Network analysis tools (tcpdump, wireshark)
- System monitoring (top, htop, iostat)
- Application-specific debug modes

## Debug Workflow
1. Reproduce the issue consistently
2. Check logs for error messages
3. Isolate the failing component
4. Test with minimal configuration
5. Apply fix and verify

    cat << 'EOF'
# Fakerjs — Performance Optimization

## Key Metrics
- Response time / latency
- Throughput / operations per second
- Resource utilization (CPU, memory, I/O)
- Error rate and retry frequency

## Optimization Strategies
1. **Caching**: Reduce redundant operations
2. **Batching**: Group small operations
3. **Indexing**: Speed up data lookups
4. **Compression**: Reduce data transfer size
5. **Parallel Processing**: Utilize multiple cores

## Monitoring
- Set up baseline performance metrics
- Configure alerts for anomalies
- Track trends over time
- Regular capacity planning reviews

- Implement role-based access control
- Enable multi-factor authentication where possible
- Regularly review and rotate credentials

## Data Protection
- Encrypt data at rest and in transit
- Implement proper backup procedures
- Follow data retention policies
- Sanitize inputs to prevent injection

## Network Security
- Use firewalls and network segmentation
- Monitor for suspicious activity
- Keep all software patched and updated
- Disable unnecessary services and ports

# FontPick

Pick the right fonts. Every time. FontPick gives you selectd pairings and type scales.

## Why FontPick?

- **selectd pairings**: Tested heading + body combinations
- **Multiple styles**: Modern, classic, minimal, bold, and code fonts
- **Font stacks**: Ready-to-use CSS font-family declarations
- **Type scales**: Calculate harmonious size systems
- **Typography tips**: Principles for better font choices

## Commands

- `pair [style]` — Get font pairings (modern/classic/minimal/bold/code)
- `stack [use]` — CSS font stacks (web/email/print)
- `size [base_px]` — Generate type scale from base size (default: 16px)
- `contrast` — Typography contrast and pairing principles
- `info` — Version info
- `help` — Show commands

## Usage Examples

```bash
fontpick pair modern
fontpick pair code
fontpick stack web
fontpick size 18
fontpick contrast
```

## Style Guide

| Style | Best For |
|-------|----------|
| Modern | SaaS, tech, startups |
| Classic | Publishing, editorial |
| Minimal | Portfolio, luxury brands |
| Bold | Marketing, headlines |
| Code | Developer tools, IDEs |

# CodePal

A full-featured devtools toolkit for checking, validating, generating, formatting, linting, explaining, converting, diffing, previewing, and fixing code — with built-in logging, search, statistics, and data export.

## Commands

| Command | Description |
|---------|-------------|
| `check <input>` | Check code and log the result; without args shows recent check entries |
| `validate <input>` | Validate code input; without args shows recent validate entries |
| `generate <input>` | Generate code from a description; without args shows recent entries |
| `format <input>` | Format code; without args shows recent format entries |
| `lint <input>` | Lint code for potential issues; without args shows recent lint entries |
| `explain <input>` | Explain a code snippet or concept; without args shows recent entries |
| `convert <input>` | Convert code between languages or formats; without args shows recent entries |
| `template <input>` | Create or apply code templates; without args shows recent entries |
| `diff <input>` | Log code differences; without args shows recent diff entries |
| `preview <input>` | Preview code output; without args shows recent preview entries |
| `fix <input>` | Record a code fix; without args shows recent fix entries |
| `report <input>` | Generate a code report; without args shows recent report entries |
| `stats` | Show summary statistics across all log categories |
| `export <fmt>` | Export all data (json, csv, or txt) |
| `search <term>` | Search across all logged entries for a keyword |
| `recent` | Show the 20 most recent entries from the activity log |
| `status` | Health check — version, data dir, total entries, disk usage, last activity |
| `help` | Show all available commands |
| `version` | Print version (v2.0.0) |

## Usage

```bash
codepal <command> [args]
```

Each command with arguments logs the input with a timestamp to a category-specific log file. Running a command with no arguments shows the most recent entries for that category.

## Data Storage

- **Default location**: `~/.local/share/codepal`
- **Log files**: Each command has its own log file (e.g., `check.log`, `lint.log`, `generate.log`)
- **History**: All actions are also recorded in `history.log` with timestamps
- **Export formats**: JSON (structured array of objects), CSV (type/time/value columns), plain text (grouped by category)

## Requirements

- Bash 4+ (strict mode: `set -euo pipefail`)
- No external dependencies or API keys required
- Standard Unix tools (`date`, `wc`, `grep`, `du`, `head`, `tail`)

## When to Use

1. **Code review tracking** — Use `check`, `lint`, and `validate` to log issues discovered during code review sessions, then `search` to find them later
2. **Learning unfamiliar codebases** — Use `explain` to document your understanding of code patterns, then `report` to create summaries
3. **Code generation and templating** — Use `generate` to log code generation prompts and `template` to track template usage
4. **Diffing and debugging** — Use `diff` to record code changes and `fix` to document bug fixes, creating an audit trail
5. **Team metrics and reporting** — Use `stats` for activity summaries, `export json` to feed into dashboards, and `recent` for quick status checks

## Examples

```bash
# Check a function
codepal check "validateEmail() is missing null check"

# Generate a code snippet description
codepal generate "React hook for debounced search"

# Lint a file
codepal lint "server.js:42 — unused variable 'config'"

# Explain a concept
codepal explain "JavaScript closure in event handler"

# Record a diff
codepal diff "Refactored auth middleware to use async/await"

# Fix a bug
codepal fix "Off-by-one error in pagination logic"

# View aggregate statistics
codepal stats

# Export all logged data as CSV
codepal export csv

# Search for entries about authentication
codepal search "auth"

# Show recent activity
codepal recent

# Health check
codepal status
```

## Output

- Command results print to stdout
- Entries are timestamped (`YYYY-MM-DD HH:MM`) and persisted to `~/.local/share/codepal/<category>.log`
- Export files are written to `~/.local/share/codepal/export.<fmt>` with a byte count confirmation

# Core — Common Patterns & Best Practices

## Design Patterns
1. **Standard Pattern**: The most common approach for core
2. **Scalable Pattern**: For high-volume or distributed scenarios
3. **Resilient Pattern**: For fault-tolerant implementations

## Best Practices
- Follow the principle of least privilege
- Use version control for all configurations
- Implement comprehensive logging
- Test changes in staging before production
- Document all custom configurations

## Anti-Patterns to Avoid
- Hardcoding credentials or configuration
- Skipping validation and error handling
- Ignoring monitoring and alerting
- Making changes without documentation
- Over-engineering simple solutions
EOF
}

cmd_debugging() {
    cat << 'EOF'
# Core — Debugging Guide

## Common Errors
1. **Connection refused**: Check service status and network
2. **Permission denied**: Verify credentials and access rights
3. **Timeout**: Check network, increase limits, optimize queries
4. **Invalid input**: Validate data format and encoding

## Debugging Tools
- Built-in logging and diagnostics
- Network analysis tools (tcpdump, wireshark)
- System monitoring (top, htop, iostat)
- Application-specific debug modes

## Debug Workflow
1. Reproduce the issue consistently
2. Check logs for error messages
3. Isolate the failing component
4. Test with minimal configuration
5. Apply fix and verify
EOF
}

cmd_performance() {
    cat << 'EOF'
# Core — Performance Optimization

## Key Metrics
- Response time / latency
- Throughput / operations per second
- Resource utilization (CPU, memory, I/O)
- Error rate and retry frequency

## Optimization Strategies
1. **Caching**: Reduce redundant operations
2. **Batching**: Group small operations
3. **Indexing**: Speed up data lookups
4. **Compression**: Reduce data transfer size
5. **Parallel Processing**: Utilize multiple cores

## Monitoring
- Set up baseline performance metrics
- Configure alerts for anomalies
- Track trends over time
- Regular capacity planning reviews
EOF
}

cmd_security() {
    cat << 'EOF'
# Core — Security Considerations

## Authentication & Authorization
- Use strong, unique credentials
- Implement role-based access control
- Enable multi-factor authentication where possible
- Regularly review and rotate credentials

## Data Protection
- Encrypt data at rest and in transit
- Implement proper backup procedures
- Follow data retention policies
- Sanitize inputs to prevent injection

## Network Security
- Use firewalls and network segmentation
- Monitor for suspicious activity
- Keep all software patched and updated
- Disable unnecessary services and ports
EOF
}

cmd_migration() {
    cat << 'EOF'
# Core — Migration & Upgrade Guide

## Pre-Migration Checklist
- [ ] Current system fully documented
- [ ] Complete backup taken and verified
- [ ] Target environment prepared
- [ ] Rollback plan documented
- [ ] Stakeholders notified

## Migration Steps
1. Prepare target environment
2. Export data from source
3. Transform data if needed
4. Import to target
5. Verify data integrity
6. Update configurations
7. Test all functionality
8. Switch traffic / go live

## Post-Migration
- Monitor for errors and performance
- Verify all integrations working
- Update documentation
- Decommission old system after confirmation

# Core — Quick Reference

## Essential Commands
| Command | Description |
|---------|-------------|
| help | Show available commands |
| version | Display version info |
| intro | Overview and fundamentals |
| troubleshooting | Common problems and fixes |

## Common Workflows
1. **Setup**: install → configure → verify → test
2. **Daily**: check → monitor → report → review
3. **Issue**: diagnose → isolate → fix → verify → document

## Key Shortcuts
- Use tab completion for commands
- Check logs first when troubleshooting
- Always backup before making changes
- Document everything you change

# Cloud SDK

Developer workflow automation tool for project lifecycle management. Provides commands for initializing projects, running checks, building, testing, deploying, managing configuration, generating templates, producing documentation, and cleaning build artifacts — all from a single CLI interface.

## Commands

| Command | Description |
|---------|-------------|
| `cloud-sdk init` | Initialize a new project in the current working directory |
| `cloud-sdk check` | Run lint, type-check, and test passes against the project |
| `cloud-sdk build` | Build the project artifacts |
| `cloud-sdk test` | Execute the full test suite |
| `cloud-sdk deploy` | Show the deployment pipeline guide (build → test → stage → prod) |
| `cloud-sdk config` | Display or manage project configuration (`config.json`) |
| `cloud-sdk status` | Check overall project health and status |
| `cloud-sdk template <name>` | Generate a code template for the given component name |
| `cloud-sdk docs` | Generate project documentation |
| `cloud-sdk clean` | Remove build artifacts and temporary files |
| `cloud-sdk help` | Show the built-in help message with all commands |
| `cloud-sdk version` | Print the current version (v2.0.0) |

## Data Storage

All operational data is stored in `~/.local/share/cloud-sdk/` by default. You can override this by setting the `CLOUD_SDK_DIR` environment variable. Key files inside the data directory:

- `history.log` — timestamped log of every command executed
- `config.json` — project-level configuration (managed via `config` command)

The tool respects `XDG_DATA_HOME` if set, falling back to `$HOME/.local/share`.

## Requirements

- **Bash** 4.0+ (uses `set -euo pipefail` for strict error handling)
- **coreutils** (standard `date`, `mkdir`, `echo`)
- No external dependencies or API keys required
- Works on Linux and macOS out of the box

## When to Use

1. **Bootstrapping a new project** — run `cloud-sdk init` to set up project scaffolding quickly from the terminal without remembering per-tool init commands
2. **Pre-commit quality gates** — use `cloud-sdk check` as part of a Git pre-commit hook to run lint + type-check + tests before every commit
3. **CI/CD pipeline steps** — chain `cloud-sdk build` and `cloud-sdk test` inside your continuous integration scripts for a consistent, tool-agnostic interface
4. **Deployment checklists** — run `cloud-sdk deploy` to get a guided walkthrough of the build → test → stage → prod pipeline so nothing gets skipped
5. **Housekeeping and cleanup** — execute `cloud-sdk clean` to wipe build artifacts after releases, freeing disk space and resetting state

## Examples

```bash
# Initialize a new project in the current directory
cloud-sdk init

# Run all quality checks (lint + type-check + tests)
cloud-sdk check

# Build the project
cloud-sdk build

# Run the test suite
cloud-sdk test

# View the deployment guide
cloud-sdk deploy

# Generate a code template for a component called "service"
cloud-sdk template service

# Generate project documentation
cloud-sdk docs

# Check project health
cloud-sdk status

# Clean up build artifacts
cloud-sdk clean

# Show version
cloud-sdk version
```

## Configuration

Set the `CLOUD_SDK_DIR` environment variable to change the data directory:

```bash
export CLOUD_SDK_DIR="$HOME/my-project/.cloud-sdk"
```

Default location: `~/.local/share/cloud-sdk/`

## Output

All command output goes to stdout. Redirect to a file if needed:

```bash
cloud-sdk status > project-health.txt
```

History is automatically logged to `$DATA_DIR/history.log` with timestamps.
