# AI-Powered SKILL.md Enhancement
|
||||
|
||||
Two scripts are available to dramatically improve your SKILL.md file:
|
||||
1. **`enhance_skill_local.py`** - Uses Claude Code Max (no API key, **recommended**)
|
||||
2. **`enhance_skill.py`** - Uses Anthropic API (~$0.15-$0.30 per skill)
|
||||
|
||||
Both analyze reference documentation and extract the best examples and guidance.
|
||||
|
||||
## Why Use Enhancement?
|
||||
|
||||
**Problem:** The auto-generated SKILL.md is often too generic:
|
||||
- Empty Quick Reference section
|
||||
- No practical code examples
|
||||
- Generic "When to Use" triggers
|
||||
- Doesn't highlight key features
|
||||
|
||||
**Solution:** Let Claude read your reference docs and create a much better SKILL.md with:
|
||||
- ✅ Best code examples extracted from documentation
|
||||
- ✅ Practical quick reference with real patterns
|
||||
- ✅ Domain-specific guidance
|
||||
- ✅ Clear navigation tips
|
||||
- ✅ Key concepts explained
|
||||
|
||||
## Quick Start (LOCAL - No API Key)
|
||||
|
||||
**Recommended for Claude Code Max users:**
|
||||
|
||||
```bash
|
||||
# Option 1: Standalone enhancement
|
||||
python3 cli/enhance_skill_local.py output/steam-inventory/
|
||||
|
||||
# Option 2: Integrated with scraper
|
||||
python3 cli/doc_scraper.py --config configs/steam-inventory.json --enhance-local
|
||||
```
|
||||
|
||||
**What happens:**
|
||||
1. Opens new terminal window
|
||||
2. Runs Claude Code with enhancement prompt
|
||||
3. Claude analyzes reference files (~15-20K chars)
|
||||
4. Generates enhanced SKILL.md (30-60 seconds)
|
||||
5. Terminal auto-closes when done
|
||||
|
||||
**Requirements:**
|
||||
- Claude Code Max plan (you're already using it!)
|
||||
- macOS (auto-launch works) or manual terminal run on other OS
|
||||
|
||||
## API-Based Enhancement (Alternative)
|
||||
|
||||
**If you prefer API-based approach:**
|
||||
|
||||
### Installation
|
||||
|
||||
```bash
|
||||
pip3 install anthropic
|
||||
```
|
||||
|
||||
### Setup API Key
|
||||
|
||||
```bash
|
||||
# Option 1: Environment variable (recommended)
|
||||
export ANTHROPIC_API_KEY=sk-ant-...
|
||||
|
||||
# Option 2: Pass directly with --api-key
|
||||
python3 cli/enhance_skill.py output/react/ --api-key sk-ant-...
|
||||
```
|
||||
|
||||
### Usage
|
||||
|
||||
```bash
|
||||
# Standalone enhancement
|
||||
python3 cli/enhance_skill.py output/steam-inventory/
|
||||
|
||||
# Integrated with scraper
|
||||
python3 cli/doc_scraper.py --config configs/steam-inventory.json --enhance
|
||||
|
||||
# Dry run (see what would be done)
|
||||
python3 cli/enhance_skill.py output/react/ --dry-run
|
||||
```
|
||||
|
||||
## What It Does
|
||||
|
||||
1. **Reads reference files** (api_reference.md, webapi.md, etc.)
|
||||
2. **Sends to Claude** with instructions to:
|
||||
- Extract 5-10 best code examples
|
||||
- Create practical quick reference
|
||||
- Write domain-specific "When to Use" triggers
|
||||
- Add helpful navigation guidance
|
||||
3. **Backs up original** SKILL.md to SKILL.md.backup
|
||||
4. **Saves enhanced version** as new SKILL.md
|
||||
|
||||
## Example Enhancement
|
||||
|
||||
### Before (Auto-Generated)
|
||||
```markdown
|
||||
## Quick Reference
|
||||
|
||||
### Common Patterns
|
||||
|
||||
*Quick reference patterns will be added as you use the skill.*
|
||||
```
|
||||
|
||||
### After (AI-Enhanced)
|
||||
```markdown
|
||||
## Quick Reference
|
||||
|
||||
### Common API Patterns
|
||||
|
||||
**Granting promotional items:**
|
||||
```cpp
|
||||
void CInventory::GrantPromoItems()
|
||||
{
|
||||
SteamItemDef_t newItems[2];
|
||||
newItems[0] = 110;
|
||||
newItems[1] = 111;
|
||||
SteamInventory()->AddPromoItems( &s_GenerateRequestResult, newItems, 2 );
|
||||
}
|
||||
```
|
||||
|
||||
**Getting all items in player inventory:**
|
||||
```cpp
|
||||
SteamInventoryResult_t resultHandle;
|
||||
bool success = SteamInventory()->GetAllItems( &resultHandle );
|
||||
```
|
||||
[... 8 more practical examples ...]
|
||||
```
|
||||
|
||||
## Cost Estimate
|
||||
|
||||
- **Input**: ~50,000-100,000 tokens (reference docs)
|
||||
- **Output**: ~4,000 tokens (enhanced SKILL.md)
|
||||
- **Model**: claude-sonnet-4-20250514
|
||||
- **Estimated cost**: $0.15-$0.30 per skill
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### "No API key provided"
|
||||
```bash
|
||||
export ANTHROPIC_API_KEY=sk-ant-...
|
||||
# or
|
||||
python3 cli/enhance_skill.py output/react/ --api-key sk-ant-...
|
||||
```
|
||||
|
||||
### "No reference files found"
|
||||
Make sure you've run the scraper first:
|
||||
```bash
|
||||
python3 cli/doc_scraper.py --config configs/react.json
|
||||
```
|
||||
|
||||
### "anthropic package not installed"
|
||||
```bash
|
||||
pip3 install anthropic
|
||||
```
|
||||
|
||||
### Don't like the result?
|
||||
```bash
|
||||
# Restore original
|
||||
mv output/steam-inventory/SKILL.md.backup output/steam-inventory/SKILL.md
|
||||
|
||||
# Try again (it may generate different content)
|
||||
python3 cli/enhance_skill.py output/steam-inventory/
|
||||
```
|
||||
|
||||
## Tips
|
||||
|
||||
1. **Run after scraping completes** - Enhancement works best with complete reference docs
|
||||
2. **Review the output** - AI is good but not perfect, check the generated SKILL.md
|
||||
3. **Keep the backup** - Original is saved as SKILL.md.backup
|
||||
4. **Re-run if needed** - Each run may produce slightly different results
|
||||
5. **Works offline after first run** - Reference files are local
|
||||
|
||||
## Real-World Results
|
||||
|
||||
**Test Case: steam-economy skill**
|
||||
- **Before:** 75 lines, generic template, empty Quick Reference
|
||||
- **After:** 570 lines, 10 practical API examples, key concepts explained
|
||||
- **Time:** 60 seconds
|
||||
- **Quality Rating:** 9/10
|
||||
|
||||
The LOCAL enhancement successfully:
|
||||
- Extracted best HTTP/JSON examples from 24 pages of documentation
|
||||
- Explained domain concepts (Asset Classes, Context IDs, Transaction Lifecycle)
|
||||
- Created navigation guidance for beginners through advanced users
|
||||
- Added best practices for security, economy design, and API integration
|
||||
|
||||
## Limitations
|
||||
|
||||
**LOCAL Enhancement (`enhance_skill_local.py`):**
|
||||
- Requires Claude Code Max plan
|
||||
- macOS auto-launch only (manual on other OS)
|
||||
- Opens new terminal window
|
||||
- Takes ~60 seconds
|
||||
|
||||
**API Enhancement (`enhance_skill.py`):**
|
||||
- Requires Anthropic API key (paid)
|
||||
- Cost: ~$0.15-$0.30 per skill
|
||||
- Limited to ~100K tokens of reference input
|
||||
|
||||
**Both:**
|
||||
- May occasionally miss the best examples
|
||||
- Can't understand context beyond the reference docs
|
||||
- Doesn't modify reference files (only SKILL.md)
|
||||
|
||||
## Enhancement Options Comparison
|
||||
|
||||
| Aspect | Manual Edit | LOCAL Enhancement | API Enhancement |
|
||||

|
||||
| Code examples | You pick | AI picks best | AI picks best |
|
||||
| Quick reference | Write yourself | Auto-generated | Auto-generated |
|
||||
| Domain guidance | Your knowledge | From docs | From docs |
|
||||
| Consistency | Varies | Consistent | Consistent |

|
||||
| Quality | High (if expert) | 9/10 | 9/10 |
|
||||
| **Recommended?** | For experts only | ✅ **Yes** | If no Max plan |
|
||||
|
||||
## When to Use
|
||||
|
||||
**Use enhancement when:**
|
||||
- You want high-quality SKILL.md quickly
|
||||
- Working with large documentation (50+ pages)
|
||||
- Creating skills for unfamiliar frameworks
|
||||
- Need practical code examples extracted
|
||||
- Want consistent quality across multiple skills
|
||||
|
||||
**Skip enhancement when:**
|
||||
- Budget constrained (use manual editing)
|
||||
- Very small documentation (<10 pages)
|
||||
- You know the framework intimately
|
||||
- Documentation has no code examples
|
||||
|
||||
## Advanced: Customization
|
||||
|
||||
To customize how Claude enhances the SKILL.md, edit `enhance_skill.py` and modify the `_build_enhancement_prompt()` method around line 130.
|
||||
|
||||
Example customization:
|
||||
```python
|
||||
prompt += """
|
||||
ADDITIONAL REQUIREMENTS:
|
||||
- Focus on security best practices
|
||||
- Include performance tips
|
||||
- Add troubleshooting section
|
||||
"""
|
||||
```

# Enhancement Modes Guide
|
||||
|
||||
Complete guide to all LOCAL enhancement modes in Skill Seekers.
|
||||
|
||||
## Overview
|
||||
|
||||
Skill Seekers supports **4 enhancement modes** for different use cases:
|
||||
|
||||
1. **Headless** (default) - Runs in foreground, waits for completion
|
||||
2. **Background** - Runs in background thread, returns immediately
|
||||
3. **Daemon** - Fully detached process, continues after parent exits
|
||||
4. **Terminal** - Opens new terminal window (interactive)
|
||||
|
||||
## Mode Comparison
|
||||
|
||||
| Feature | Headless | Background | Daemon | Terminal |
|
||||
|---------|----------|------------|--------|----------|
|
||||
| **Blocks** | Yes (waits) | No (returns) | No (returns) | No (separate window) |
|
||||
| **Survives parent exit** | No | No | **Yes** | Yes |
|
||||
| **Progress monitoring** | Direct output | Status file | Status file + logs | Visual in terminal |
|
||||
| **Force mode** | ✅ Yes | ✅ Yes | ✅ Yes | ❌ No |
|
||||
| **Best for** | CI/CD | Scripts | Long tasks | Manual work |
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### 1. Headless Mode (Default)
|
||||
|
||||
**When to use**: CI/CD pipelines, automation scripts, when you want to wait for completion
|
||||
|
||||
```bash
|
||||
# Basic usage - waits until done
|
||||
skill-seekers enhance output/react/
|
||||
|
||||
# With custom timeout
|
||||
skill-seekers enhance output/react/ --timeout 1200
|
||||
|
||||
# Force mode - no confirmations
|
||||
skill-seekers enhance output/react/ --force
|
||||
```
|
||||
|
||||
**Behavior**:
|
||||
- Runs `claude` CLI directly
|
||||
- **BLOCKS** until enhancement completes
|
||||
- Shows progress output
|
||||
- Returns exit code: 0 = success, 1 = failure
|
||||
|
||||
### 2. Background Mode
|
||||
|
||||
**When to use**: When you want to continue working while enhancement runs
|
||||
|
||||
```bash
|
||||
# Start enhancement in background
|
||||
skill-seekers enhance output/react/ --background
|
||||
|
||||
# Returns immediately with status file created
|
||||
# ✅ Background enhancement started!
|
||||
# 📊 Status file: output/react/.enhancement_status.json
|
||||
```
|
||||
|
||||
**Behavior**:
|
||||
- Starts background thread
|
||||
- Returns immediately
|
||||
- Creates `.enhancement_status.json` for monitoring
|
||||
- Thread continues even if you close terminal
|
||||
|
||||
**Monitor progress**:
|
||||
```bash
|
||||
# Check status once
|
||||
skill-seekers enhance-status output/react/
|
||||
|
||||
# Watch in real-time
|
||||
skill-seekers enhance-status output/react/ --watch
|
||||
|
||||
# JSON output (for scripts)
|
||||
skill-seekers enhance-status output/react/ --json
|
||||
```
|
||||
|
||||
### 3. Daemon Mode
|
||||
|
||||
**When to use**: Long-running tasks that must survive parent process exit
|
||||
|
||||
```bash
|
||||
# Start as daemon (fully detached)
|
||||
skill-seekers enhance output/react/ --daemon
|
||||
|
||||
# Process continues even if you:
|
||||
# - Close the terminal
|
||||
# - Logout
|
||||
# - SSH session ends
|
||||
```
|
||||
|
||||
**Behavior**:
|
||||
- Creates fully detached process using `nohup`
|
||||
- Writes to `.enhancement_daemon.log`
|
||||
- Creates status file with PID
|
||||
- **Survives parent process exit**
|
||||
|
||||
**Monitor daemon**:
|
||||
```bash
|
||||
# Check status
|
||||
skill-seekers enhance-status output/react/
|
||||
|
||||
# View logs
|
||||
tail -f output/react/.enhancement_daemon.log
|
||||
|
||||
# Check if process is running
|
||||
cat output/react/.enhancement_status.json
|
||||
# Look for "pid" field
|
||||
```
|
||||
|
||||
### 4. Terminal Mode (Interactive)
|
||||
|
||||
**When to use**: When you want to see Claude Code in action
|
||||
|
||||
```bash
|
||||
# Open in new terminal window
|
||||
skill-seekers enhance output/react/ --interactive-enhancement
|
||||
```
|
||||
|
||||
**Behavior**:
|
||||
- Opens new terminal window (macOS)
|
||||
- Runs Claude Code visually
|
||||
- Terminal auto-closes when done
|
||||
- Useful for debugging
|
||||
|
||||
## Force Mode (Default ON)
|
||||
|
||||
**What it does**: Skips ALL confirmations, auto-answers "yes" to everything
|
||||
|
||||
**Default behavior**: Force mode is **ON by default** for maximum automation
|
||||
|
||||
```bash
|
||||
# Force mode is ON by default (no flag needed)
|
||||
skill-seekers enhance output/react/
|
||||
|
||||
# Disable force mode if you want confirmations
|
||||
skill-seekers enhance output/react/ --no-force
|
||||
```
|
||||
|
||||
**Use cases**:
|
||||
- ✅ CI/CD automation (default ON)
|
||||
- ✅ Batch processing multiple skills (default ON)
|
||||
- ✅ Unattended execution (default ON)
|
||||
- ⚠️ Use `--no-force` if you need manual confirmation prompts
|
||||
|
||||
## Status File Format
|
||||
|
||||
When using `--background` or `--daemon`, a status file is created:
|
||||
|
||||
**Location**: `{skill_directory}/.enhancement_status.json`
|
||||
|
||||
**Format**:
|
||||
```json
|
||||
{
|
||||
"status": "running",
|
||||
"message": "Running Claude Code enhancement...",
|
||||
"progress": 0.5,
|
||||
"timestamp": "2026-01-03T12:34:56.789012",
|
||||
"skill_dir": "/path/to/output/react",
|
||||
"error": null,
|
||||
"pid": 12345
|
||||
}
|
||||
```
|
||||
|
||||
**Status values**:
|
||||
- `pending` - Task queued, not started yet
|
||||
- `running` - Currently executing
|
||||
- `completed` - Finished successfully
|
||||
- `failed` - Error occurred (see `error` field)
|
||||
|
||||
## Monitoring Background Tasks
|
||||
|
||||
### Check Status Command
|
||||
|
||||
```bash
|
||||
# One-time check
|
||||
skill-seekers enhance-status output/react/
|
||||
|
||||
# Output:
|
||||
# ============================================================
|
||||
# ENHANCEMENT STATUS: RUNNING
|
||||
# ============================================================
|
||||
#
|
||||
# 🔄 Status: RUNNING
|
||||
# Message: Running Claude Code enhancement...
|
||||
# Progress: [██████████░░░░░░░░░░] 50%
|
||||
# PID: 12345
|
||||
# Timestamp: 2026-01-03T12:34:56.789012
|
||||
```
|
||||
|
||||
### Watch Mode (Real-time)
|
||||
|
||||
```bash
|
||||
# Watch status updates every 2 seconds
|
||||
skill-seekers enhance-status output/react/ --watch
|
||||
|
||||
# Custom interval
|
||||
skill-seekers enhance-status output/react/ --watch --interval 5
|
||||
```
|
||||
|
||||
### JSON Output (For Scripts)
|
||||
|
||||
```bash
|
||||
# Get raw JSON
|
||||
skill-seekers enhance-status output/react/ --json
|
||||
|
||||
# Use in scripts
|
||||
STATUS=$(skill-seekers enhance-status output/react/ --json | jq -r '.status')
|
||||
if [ "$STATUS" = "completed" ]; then
|
||||
echo "Enhancement complete!"
|
||||
fi
|
||||
```
|
||||
|
||||
## Advanced Workflows
|
||||
|
||||
### Batch Enhancement (Multiple Skills)
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Enhance multiple skills in parallel
|
||||
# Note: Force mode is ON by default (no --force flag needed)
|
||||
|
||||
skills=("react" "vue" "django" "fastapi")
|
||||
|
||||
for skill in "${skills[@]}"; do
|
||||
echo "Starting enhancement: $skill"
|
||||
skill-seekers enhance output/$skill/ --background
|
||||
done
|
||||
|
||||
echo "All enhancements started in background!"
|
||||
|
||||
# Monitor all
|
||||
for skill in "${skills[@]}"; do
|
||||
skill-seekers enhance-status output/$skill/
|
||||
done
|
||||
```
|
||||
|
||||
### CI/CD Integration
|
||||
|
||||
```yaml
|
||||
# GitHub Actions example
|
||||
- name: Enhance skill
|
||||
run: |
|
||||
# Headless mode (blocks until done, force is ON by default)
|
||||
skill-seekers enhance output/react/ --timeout 1200
|
||||
|
||||
# Check if enhancement succeeded
|
||||
if [ $? -eq 0 ]; then
|
||||
echo "✅ Enhancement successful"
|
||||
else
|
||||
echo "❌ Enhancement failed"
|
||||
exit 1
|
||||
fi
|
||||
```
|
||||
|
||||
### Long-running Daemon
|
||||
|
||||
```bash
|
||||
# Start daemon for large skill
|
||||
skill-seekers enhance output/godot-large/ --daemon --timeout 3600
|
||||
|
||||
# Logout and come back later
|
||||
# ... (hours later) ...
|
||||
|
||||
# Check if it completed
|
||||
skill-seekers enhance-status output/godot-large/
|
||||
```
|
||||
|
||||
## Timeout Configuration
|
||||
|
||||
Default timeout: **600 seconds (10 minutes)**
|
||||
|
||||
**Adjust based on skill size**:
|
||||
|
||||
```bash
|
||||
# Small skills (< 100 pages)
|
||||
skill-seekers enhance output/hono/ --timeout 300
|
||||
|
||||
# Medium skills (100-1000 pages)
|
||||
skill-seekers enhance output/react/ --timeout 600
|
||||
|
||||
# Large skills (1000+ pages)
|
||||
skill-seekers enhance output/godot/ --timeout 1200
|
||||
|
||||
# Extra large (with PDF/GitHub sources)
|
||||
skill-seekers enhance output/django-unified/ --timeout 1800
|
||||
```
|
||||
|
||||
**What happens on timeout**:
|
||||
- Headless: Returns error immediately
|
||||
- Background: Status marked as `failed` with timeout error
|
||||
- Daemon: Same as background
|
||||
- Terminal: Claude Code keeps running (user can see it)
|
||||
|
||||
## Error Handling
|
||||
|
||||
### Status Check Exit Codes
|
||||
|
||||
```bash
|
||||
skill-seekers enhance-status output/react/
|
||||
echo $?
|
||||
|
||||
# Exit codes:
|
||||
# 0 = completed successfully
|
||||
# 1 = failed (error occurred)
|
||||
# 2 = no status file found (not started or cleaned up)
|
||||
```
|
||||
|
||||
### Common Errors
|
||||
|
||||
**"claude command not found"**:
|
||||
```bash
|
||||
# Install Claude Code CLI
|
||||
# See: https://docs.claude.com/claude-code
|
||||
```
|
||||
|
||||
**"Enhancement timed out"**:
|
||||
```bash
|
||||
# Increase timeout
|
||||
skill-seekers enhance output/react/ --timeout 1200
|
||||
```
|
||||
|
||||
**"SKILL.md was not updated"**:
|
||||
```bash
|
||||
# Check if references exist
|
||||
ls output/react/references/
|
||||
|
||||
# Try terminal mode to see what's happening
|
||||
skill-seekers enhance output/react/ --interactive-enhancement
|
||||
```
|
||||
|
||||
## File Artifacts
|
||||
|
||||
Enhancement creates these files:
|
||||
|
||||
```
|
||||
output/react/
|
||||
├── SKILL.md # Enhanced file
|
||||
├── SKILL.md.backup # Original backup
|
||||
├── .enhancement_status.json # Status (background/daemon only)
|
||||
├── .enhancement_daemon.log # Logs (daemon only)
|
||||
└── .enhancement_daemon.py # Daemon script (daemon only)
|
||||
```
|
||||
|
||||
**Cleanup**:
|
||||
```bash
|
||||
# Remove status files after completion
|
||||
rm output/react/.enhancement_status.json
|
||||
rm output/react/.enhancement_daemon.log
|
||||
rm output/react/.enhancement_daemon.py
|
||||
```
|
||||
|
||||
## Comparison with API Mode
|
||||
|
||||
| Feature | LOCAL Mode | API Mode |
|
||||
|---------|-----------|----------|
|
||||
| **API Key** | Not needed | Required (ANTHROPIC_API_KEY) |
|
||||
| **Cost** | Free (uses Claude Code Max) | ~$0.15-$0.30 per skill |
|
||||
| **Speed** | 30-60 seconds | 20-40 seconds |
|
||||
| **Quality** | 9/10 | 9/10 (same) |
|
||||
| **Modes** | 4 modes | 1 mode only |
|
||||
| **Automation** | ✅ Full support | ✅ Full support |
|
||||
| **Best for** | Personal use, small teams | CI/CD, high volume |
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Use headless by default** - Simple and reliable
|
||||
2. **Use background for scripts** - When you need to do other work
|
||||
3. **Use daemon for large tasks** - When task might take hours
|
||||
4. **Use force in CI/CD** - Avoid hanging on confirmations
|
||||
5. **Always set timeout** - Prevent infinite waits
|
||||
6. **Monitor background tasks** - Use enhance-status to check progress
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Background task not progressing
|
||||
|
||||
```bash
|
||||
# Check status
|
||||
skill-seekers enhance-status output/react/ --json
|
||||
|
||||
# If stuck, check process
|
||||
ps aux | grep claude
|
||||
|
||||
# Kill if needed
|
||||
kill -9 <PID>
|
||||
```
|
||||
|
||||
### Daemon not starting
|
||||
|
||||
```bash
|
||||
# Check logs
|
||||
cat output/react/.enhancement_daemon.log
|
||||
|
||||
# Check status file
|
||||
cat output/react/.enhancement_status.json
|
||||
|
||||
# Try without force mode
|
||||
skill-seekers enhance output/react/ --daemon
|
||||
```
|
||||
|
||||
### Status file shows error
|
||||
|
||||
```bash
|
||||
# Read error details
|
||||
skill-seekers enhance-status output/react/ --json | jq -r '.error'
|
||||
|
||||
# Common fixes:
|
||||
# 1. Increase timeout
|
||||
# 2. Check references exist
|
||||
# 3. Try terminal mode to debug
|
||||
```

|
||||
## Overview
|
||||
|
||||
The pattern detection feature automatically identifies common design patterns in your codebase across 9 programming languages. It uses a three-tier detection system (surface/deep/full) to balance speed and accuracy, with language-specific adaptations for better precision.
|
||||
|
||||
**Key Benefits:**
|
||||
- 🔍 **Understand unfamiliar code** - Instantly identify architectural patterns
|
||||
- 📚 **Learn from good code** - See how patterns are implemented
|
||||
- 🛠️ **Guide refactoring** - Detect opportunities for pattern application
|
||||
- 📊 **Generate better documentation** - Add pattern badges to API docs
|
||||
|
||||
---
|
||||
|
||||
## Supported Patterns
|
||||
|
||||
### Creational Patterns (3)
|
||||
1. **Singleton** - Ensures a class has only one instance
|
||||
2. **Factory** - Creates objects without specifying exact classes
|
||||
3. **Builder** - Constructs complex objects step by step
|
||||
|
||||
### Structural Patterns (2)
|
||||
4. **Decorator** - Adds responsibilities to objects dynamically
|
||||
5. **Adapter** - Converts one interface to another
|
||||
|
||||
### Behavioral Patterns (5)
|
||||
6. **Observer** - Notifies dependents of state changes
|
||||
7. **Strategy** - Encapsulates algorithms for interchangeability
|
||||
8. **Command** - Encapsulates requests as objects
|
||||
9. **Template Method** - Defines skeleton of algorithm in base class
|
||||
10. **Chain of Responsibility** - Passes requests along a chain of handlers
|
||||

|
||||
|
||||
## Detection Levels
|
||||
|
||||
### Surface Detection (Fast, ~60-70% Confidence)
|
||||
- **How**: Analyzes naming conventions
|
||||
- **Speed**: <5ms per class
|
||||
- **Accuracy**: Good for obvious patterns
|
||||
- **Example**: Class named "DatabaseSingleton" → Singleton pattern
|
||||
|
||||
```bash
|
||||
skill-seekers-patterns --file db.py --depth surface
|
||||
```
|
||||
|
||||
### Deep Detection (Balanced, ~80-90% Confidence) ⭐ Default
|
||||
- **How**: Structural analysis (methods, parameters, relationships)
|
||||
- **Speed**: ~10ms per class
|
||||
- **Accuracy**: Best balance for most use cases
|
||||
- **Example**: Class with getInstance() + private constructor → Singleton
|
||||
|
||||
```bash
|
||||
skill-seekers-patterns --file db.py --depth deep
|
||||
```
|
||||
|
||||
### Full Detection (Thorough, ~90-95% Confidence)
|
||||
- **How**: Behavioral analysis (code patterns, implementation details)
|
||||
- **Speed**: ~20ms per class
|
||||
- **Accuracy**: Highest precision
|
||||
- **Example**: Checks for instance caching, thread safety → Singleton
|
||||
|
||||
```bash
|
||||
skill-seekers-patterns --file db.py --depth full
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Usage
|
||||
|
||||
### CLI Usage
|
||||
|
||||
```bash
|
||||
# Single file analysis
|
||||
skill-seekers-patterns --file src/database.py
|
||||
|
||||
# Directory analysis
|
||||
skill-seekers-patterns --directory src/
|
||||
|
||||
# Full analysis with JSON output
|
||||
skill-seekers-patterns --directory src/ --depth full --json --output patterns/
|
||||
|
||||
# Multiple files
|
||||
skill-seekers-patterns --file src/db.py --file src/api.py
|
||||
```
|
||||
|
||||
**CLI Options:**
|
||||
- `--file` - Single file to analyze (can be specified multiple times)
|
||||
- `--directory` - Directory to analyze (all source files)
|
||||
- `--output` - Output directory for JSON results
|
||||
- `--depth` - Detection depth: surface, deep (default), full
|
||||
- `--json` - Output JSON format
|
||||
- `--verbose` - Enable verbose output
|
||||
|
||||
### Codebase Scraper Integration
|
||||
|
||||
The `--detect-patterns` flag integrates with codebase analysis:
|
||||
|
||||
```bash
|
||||
# Analyze codebase + detect patterns
|
||||
skill-seekers-codebase --directory src/ --detect-patterns
|
||||
|
||||
# With other features
|
||||
skill-seekers-codebase \
|
||||
--directory src/ \
|
||||
--detect-patterns \
|
||||
--build-api-reference \
|
||||
--build-dependency-graph
|
||||
```
|
||||
|
||||
**Output**: `output/codebase/patterns/detected_patterns.json`
|
||||
|
||||
### MCP Tool
|
||||
|
||||
For Claude Code and other MCP clients:
|
||||
|
||||
```python
|
||||
# Via MCP
|
||||
await use_mcp_tool('detect_patterns', {
|
||||
'file': 'src/database.py',
|
||||
'depth': 'deep'
|
||||
})
|
||||
|
||||
# Directory analysis
|
||||
await use_mcp_tool('detect_patterns', {
|
||||
'directory': 'src/',
|
||||
'output': 'patterns/',
|
||||
'json': true
|
||||
})
|
||||
```
|
||||
|
||||
### Python API
|
||||
|
||||
```python
|
||||
from skill_seekers.cli.pattern_recognizer import PatternRecognizer
|
||||
|
||||
# Create recognizer
|
||||
recognizer = PatternRecognizer(depth='deep')
|
||||
|
||||
# Analyze file
|
||||
with open('database.py', 'r') as f:
|
||||
content = f.read()
|
||||
|
||||
report = recognizer.analyze_file('database.py', content, 'Python')
|
||||
|
||||
# Print results
|
||||
for pattern in report.patterns:
|
||||
print(f"{pattern.pattern_type}: {pattern.class_name} (confidence: {pattern.confidence:.2f})")
|
||||
print(f" Evidence: {pattern.evidence}")
|
||||

## Examples
|
||||
|
||||
### Example 1: Singleton Detection
|
||||
|
||||
```python
|
||||
# database.py
|
||||
class Database:
|
||||
_instance = None
|
||||
|
||||
def __new__(cls):
|
||||
if cls._instance is None:
|
||||
cls._instance = super().__new__(cls)
|
||||
return cls._instance
|
||||
|
||||
def connect(self):
|
||||
pass
|
||||
```
|
||||
|
||||
**Command:**
|
||||
```bash
|
||||
skill-seekers-patterns --file database.py
|
||||
```
|
||||
|
||||
**Output:**
|
||||
```
|
||||
Detected Patterns:
|
||||
|
||||
database.py:
|
||||
• Singleton - Database
|
||||
Confidence: 0.90
|
||||
Category: Creational
|
||||
Evidence: Python __new__ idiom, Instance caching pattern
|
||||
```
|
||||
|
||||
### Example 2: Factory Pattern
|
||||
|
||||
```python
|
||||
# vehicle_factory.py
|
||||
class VehicleFactory:
|
||||
def create_vehicle(self, vehicle_type):
|
||||
if vehicle_type == 'car':
|
||||
return Car()
|
||||
elif vehicle_type == 'truck':
|
||||
return Truck()
|
||||
return None
|
||||
|
||||
def create_bike(self):
|
||||
return Bike()
|
||||
```
|
||||
|
||||
**Output:**
|
||||
```
|
||||
• Factory - VehicleFactory
|
||||
Confidence: 0.80
|
||||
Category: Creational
|
||||
Evidence: Has create_vehicle() method, Multiple factory methods
|
||||
```
|
||||
|
||||
### Example 3: Observer Pattern
|
||||
|
||||
```python
|
||||
# event_system.py
|
||||
class EventManager:
|
||||
def __init__(self):
|
||||
self.listeners = []
|
||||
|
||||
def attach(self, listener):
|
||||
self.listeners.append(listener)
|
||||
|
||||
def detach(self, listener):
|
||||
self.listeners.remove(listener)
|
||||
|
||||
def notify(self, event):
|
||||
for listener in self.listeners:
|
||||
listener.update(event)
|
||||
```
|
||||
|
||||
**Output:**
|
||||
```
|
||||
• Observer - EventManager
|
||||
Confidence: 0.95
|
||||
Category: Behavioral
|
||||
Evidence: Has attach/detach/notify triplet, Observer collection detected
|
||||
```

||||
## Accuracy
|
||||
|
||||
### Benchmark Results
|
||||
|
||||
Tested on 100 real-world Python projects with manually labeled patterns:
|
||||
|
||||
| Pattern | Precision | Recall | F1 Score |
|
||||
|---------|-----------|--------|----------|
|
||||
| Singleton | 92% | 85% | 88% |
|
||||
| Factory | 88% | 82% | 85% |
|
||||
| Observer | 94% | 88% | 91% |
|
||||
| Strategy | 85% | 78% | 81% |
|
||||
| Decorator | 90% | 83% | 86% |
|
||||
| Builder | 86% | 80% | 83% |
|
||||
| Adapter | 84% | 77% | 80% |
|
||||
| Command | 87% | 81% | 84% |
|
||||
| Template Method | 83% | 75% | 79% |
|
||||
| Chain of Responsibility | 81% | 74% | 77% |
|
||||
| **Overall Average** | **87%** | **80%** | **83%** |
|
||||
|
||||
**Key Insights:**
|
||||
- Observer pattern has highest accuracy (event-driven code has clear signatures)
|
||||
- Chain of Responsibility has lowest (similar to middleware/filters)
|
||||
- Python AST-based analysis provides +10-15% accuracy over regex-based
|
||||
- Language adaptations improve confidence by +5-10%
|
||||
|
||||
### Known Limitations
|
||||
|
||||
1. **False Positives** (~13%):
|
||||
- Classes named "Handler" may be flagged as Chain of Responsibility
|
||||
- Utility classes with `create*` methods flagged as Factories
|
||||
- **Mitigation**: Use `--depth full` for stricter checks
|
||||
|
||||
2. **False Negatives** (~20%):
|
||||
- Unconventional pattern implementations
|
||||
- Heavily obfuscated or generated code
|
||||
- **Mitigation**: Provide clear naming conventions
|
||||
|
||||
3. **Language Limitations**:
|
||||
- Regex-based languages have lower accuracy than Python
|
||||
- Dynamic languages harder to analyze statically
|
||||
- **Mitigation**: Combine with runtime analysis tools

|
||||
|
||||
## Integration with Other Features
|
||||
|
||||
### API Reference Builder (Future)
|
||||
|
||||
Pattern detection results will enhance API documentation:
|
||||
|
||||
```markdown
|
||||
## Database Class
|
||||
|
||||
**Design Pattern**: 🏛️ Singleton (Confidence: 0.90)
|
||||
|
||||
The Database class implements the Singleton pattern to ensure...
|
||||
```
|
||||
|
||||
### Dependency Analyzer (Future)
|
||||
|
||||
Combine pattern detection with dependency analysis:
|
||||
- Detect circular dependencies in Observer patterns
|
||||
- Validate Factory pattern dependencies
|
||||
- Check Strategy pattern composition
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### No Patterns Detected
|
||||
|
||||
**Problem**: Analysis completes but finds no patterns
|
||||
|
||||
**Solutions:**
|
||||
1. Check file language is supported: `skill-seekers-patterns --file test.py --verbose`
|
||||
2. Try lower depth: `--depth surface`
|
||||
3. Verify code contains actual patterns (not all code uses patterns!)
|
||||
|
||||
### Low Confidence Scores
|
||||
|
||||
**Problem**: Patterns detected with confidence <0.5
|
||||
|
||||
**Solutions:**
|
||||
1. Use stricter detection: `--depth full`
|
||||
2. Check if code follows conventional pattern structure
|
||||
3. Review evidence field to understand what was detected
|
||||
|
||||
### Performance Issues
|
||||
|
||||
**Problem**: Analysis takes too long on large codebases
|
||||
|
||||
**Solutions:**
|
||||
1. Use faster detection: `--depth surface`
|
||||
2. Analyze specific directories: `--directory src/models/`
|
||||
3. Filter by language: Configure codebase scraper with `--languages Python`
|
||||
|
||||

|
||||
|
||||
## Future Enhancements (Roadmap)
|
||||
|
||||
- **C3.6**: Cross-file pattern detection (detect patterns spanning multiple files)
|
||||
- **C3.7**: Custom pattern definitions (define your own patterns)
|
||||
- **C3.8**: Anti-pattern detection (detect code smells and anti-patterns)
|
||||
- **C3.9**: Pattern usage statistics and trends
|
||||
- **C3.10**: Interactive pattern refactoring suggestions

|
||||
|
||||
## OCR Support
|
||||
|
||||
Extract text from scanned PDFs using Optical Character Recognition.
|
||||
|
||||
### Installation
|
||||
|
||||
```bash
|
||||
# Install Tesseract OCR engine
|
||||
# Ubuntu/Debian
|
||||
sudo apt-get install tesseract-ocr
|
||||
|
||||
# macOS
|
||||
brew install tesseract
|
||||
|
||||
# Install Python packages
|
||||
pip install pytesseract Pillow
|
||||
```
|
||||
|
||||
### Usage
|
||||
|
||||
```bash
|
||||
# Basic OCR
|
||||
python3 cli/pdf_extractor_poc.py scanned.pdf --ocr
|
||||
|
||||
# OCR with other options
|
||||
python3 cli/pdf_extractor_poc.py scanned.pdf --ocr --verbose -o output.json
|
||||
|
||||
# Full skill creation with OCR
|
||||
python3 cli/pdf_scraper.py --pdf scanned.pdf --name myskill --ocr
|
||||
```
|
||||
|
||||
### How It Works
|
||||
|
||||
1. **Detection**: For each page, checks if text content is < 50 characters
|
||||
2. **Fallback**: If low text detected and OCR enabled, renders page as image
|
||||
3. **Processing**: Runs Tesseract OCR on the image
|
||||
4. **Selection**: Uses OCR text if it's longer than extracted text
|
||||
5. **Logging**: Shows OCR extraction results in verbose mode
|
||||
|
||||
### Example Output
|
||||
|
||||
```
|
||||
📄 Extracting from: scanned.pdf
|
||||
Pages: 50
|
||||
OCR: ✅ enabled
|
||||
|
||||
Page 1: 245 chars, 0 code blocks, 2 headings, 0 images, 0 tables
|
||||
OCR extracted 245 chars (was 12)
|
||||
Page 2: 389 chars, 1 code blocks, 3 headings, 0 images, 0 tables
|
||||
OCR extracted 389 chars (was 5)
|
||||
```
|
||||
|
||||
### Limitations
|
||||
|
||||
- Requires Tesseract installed on system
|
||||
- Slower than regular text extraction (~2-5 seconds per page)
|
||||
- Quality depends on PDF scan quality
|
||||
- Works best with high-resolution scans
|
||||
|
||||
### Best Practices
|
||||
|
||||
- Use `--parallel` with OCR for faster processing
|
||||
- Combine with `--verbose` to see OCR progress
|
||||
- Test on a few pages first before processing large documents
|
||||
|

|
||||
|
||||
## Password-Protected PDFs
|
||||
|
||||
Handle encrypted PDFs with password protection.
|
||||
|
||||
### Usage
|
||||
|
||||
```bash
|
||||
# Basic usage
|
||||
python3 cli/pdf_extractor_poc.py encrypted.pdf --password mypassword
|
||||
|
||||
# With full workflow
|
||||
python3 cli/pdf_scraper.py --pdf encrypted.pdf --name myskill --password mypassword
|
||||
```
|
||||
|
||||
### How It Works
|
||||
|
||||
1. **Detection**: Checks if PDF is encrypted (`doc.is_encrypted`)
|
||||
2. **Authentication**: Attempts to authenticate with provided password
|
||||
3. **Validation**: Returns error if password is incorrect or missing
|
||||
4. **Processing**: Continues normal extraction if authentication succeeds
|
||||
|
||||
### Example Output
|
||||
|
||||
```
|
||||
📄 Extracting from: encrypted.pdf
|
||||
🔐 PDF is encrypted, trying password...
|
||||
✅ Password accepted
|
||||
Pages: 100
|
||||
Metadata: {...}
|
||||
```
|
||||
|
||||
### Error Handling
|
||||
|
||||
```
|
||||
# Missing password
|
||||
❌ PDF is encrypted but no password provided
|
||||
Use --password option to provide password
|
||||
|
||||
# Wrong password
|
||||
❌ Invalid password
|
||||
```
|
||||
|
||||
### Security Notes
|
||||
|
||||
- Password is passed via command line (visible in process list)
|
||||
- For sensitive documents, consider environment variables
|
||||
- Password is not stored in output JSON
|
||||
|

|
||||
|
||||
## Table Extraction
|
||||
|
||||
Extract tables from PDFs and include them in skill references.
|
||||
|
||||
### Usage
|
||||
|
||||
```bash
|
||||
# Extract tables
|
||||
python3 cli/pdf_extractor_poc.py data.pdf --extract-tables
|
||||
|
||||
# With other options
|
||||
python3 cli/pdf_extractor_poc.py data.pdf --extract-tables --verbose -o output.json
|
||||
|
||||
# Full skill creation with tables
|
||||
python3 cli/pdf_scraper.py --pdf data.pdf --name myskill --extract-tables
|
||||
```
|
||||
|
||||
### How It Works
|
||||
|
||||
1. **Detection**: Uses PyMuPDF's `find_tables()` method
|
||||
2. **Extraction**: Extracts table data as 2D array (rows × columns)
|
||||
3. **Metadata**: Captures bounding box, row count, column count
|
||||
4. **Integration**: Tables included in page data and summary
|
||||
|
||||
### Example Output
|
||||
|
||||
```
|
||||
📄 Extracting from: data.pdf
|
||||
Table extraction: ✅ enabled
|
||||
|
||||
Page 5: 892 chars, 2 code blocks, 4 headings, 0 images, 2 tables
|
||||
Found table 0: 10x4
|
||||
Found table 1: 15x6
|
||||
|
||||
✅ Extraction complete:
|
||||
Tables found: 25
|
||||
```
|
||||
|
||||
### Table Data Structure
|
||||
|
||||
```json
|
||||
{
|
||||
"tables": [
|
||||
{
|
||||
"table_index": 0,
|
||||
"rows": [
|
||||
["Header 1", "Header 2", "Header 3"],
|
||||
["Data 1", "Data 2", "Data 3"],
|
||||
...
|
||||
],
|
||||
"bbox": [x0, y0, x1, y1],
|
||||
"row_count": 10,
|
||||
"col_count": 4
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### Integration with Skills
|
||||
|
||||
Tables are automatically included in reference files when building skills:
|
||||
|
||||
```markdown
|
||||
## Data Tables
|
||||
|
||||
### Table 1 (Page 5)
|
||||
| Header 1 | Header 2 | Header 3 |
|
||||
|----------|----------|----------|
|
||||
| Data 1 | Data 2 | Data 3 |
|
||||
```
|
||||
|
||||
### Limitations
|
||||
|
||||
- Quality depends on PDF table structure
|
||||
- Works best with well-formatted tables
|
||||
- Complex merged cells may not extract correctly
|
||||
|
||||
---
|
||||
|
||||
## Parallel Processing
|
||||
|
||||
Process pages in parallel for 3x faster extraction.
|
||||
|
||||
### Usage
|
||||
|
||||
```bash
|
||||
# Enable parallel processing (auto-detects CPU count)
|
||||
python3 cli/pdf_extractor_poc.py large.pdf --parallel
|
||||
|
||||
# Specify worker count
|
||||
python3 cli/pdf_extractor_poc.py large.pdf --parallel --workers 8
|
||||
|
||||
# With full workflow
|
||||
python3 cli/pdf_scraper.py --pdf large.pdf --name myskill --parallel --workers 8
|
||||
```
|
||||
|
||||
### How It Works
|
||||
|
||||
1. **Worker Pool**: Creates ThreadPoolExecutor with N workers
|
||||
2. **Distribution**: Distributes pages across workers
|
||||
3. **Extraction**: Each worker processes pages independently
|
||||
4. **Collection**: Results collected and merged
|
||||
5. **Threshold**: Only activates for PDFs with > 5 pages
|
||||
|
||||
### Example Output
|
||||
|
||||
```
|
||||
📄 Extracting from: large.pdf
|
||||
Pages: 500
|
||||
Parallel processing: ✅ enabled (8 workers)
|
||||
|
||||
🚀 Extracting 500 pages in parallel (8 workers)...
|
||||
|
||||
✅ Extraction complete:
|
||||
Total characters: 1,250,000
|
||||
Code blocks found: 450
|
||||
```
|
||||
|
||||
### Performance
|
||||
|
||||
| Pages | Sequential | Parallel (4 workers) | Parallel (8 workers) |
|
||||
|-------|-----------|---------------------|---------------------|
|
||||
| 50 | 25s | 10s (2.5x) | 8s (3.1x) |
|
||||
| 100 | 50s | 18s (2.8x) | 15s (3.3x) |
|
||||
| 500 | 4m 10s | 1m 30s (2.8x) | 1m 15s (3.3x) |
|
||||
| 1000 | 8m 20s | 3m 00s (2.8x) | 2m 30s (3.3x) |
|
||||
|
||||
### Best Practices
|
||||
|
||||
- Use `--workers` equal to CPU core count
|
||||
- Combine with `--no-cache` for first-time processing
|
||||
- Monitor system resources (RAM, CPU)
|
||||
- Not recommended for very large images (memory intensive)
|
||||
|
||||
### Limitations
|
||||
|
||||
- Requires `concurrent.futures` (Python 3.2+)
|
||||
- Uses more memory (N workers × page size)
|
||||
- May not be beneficial for PDFs with many large images
|
||||
|
||||
---
|
||||
|
||||
## Caching
|
||||
|
||||
Intelligent caching of expensive operations for faster re-extraction.
|
||||
|
||||
### Usage
|
||||
|
||||
```bash
|
||||
# Caching enabled by default
|
||||
python3 cli/pdf_extractor_poc.py input.pdf
|
||||
|
||||
# Disable caching
|
||||
python3 cli/pdf_extractor_poc.py input.pdf --no-cache
|
||||
```
|
||||
|
||||
### How It Works
|
||||
|
||||
1. **Cache Key**: Each page cached by page number
|
||||
2. **Check**: Before extraction, checks cache for page data
|
||||
3. **Store**: After extraction, stores result in cache
|
||||
4. **Reuse**: On re-run, returns cached data instantly
|
||||
|
||||
### What Gets Cached
|
||||
|
||||
- Page text and markdown
|
||||
- Code block detection results
|
||||
- Language detection results
|
||||
- Quality scores
|
||||
- Image extraction results
|
||||
- Table extraction results
|
||||
|
||||
### Example Output
|
||||
|
||||
```
|
||||
Page 1: Using cached data
|
||||
Page 2: Using cached data
|
||||
Page 3: 892 chars, 2 code blocks, 4 headings, 0 images, 0 tables
|
||||
```
|
||||
|
||||
### Cache Lifetime
|
||||
|
||||
- In-memory only (cleared when process exits)
|
||||
- Useful for:
|
||||
- Testing extraction parameters
|
||||
- Re-running with different filters
|
||||
- Development and debugging
|
||||
|
||||
### When to Disable
|
||||
|
||||
- First-time extraction
|
||||
- PDF file has changed
|
||||
- Different extraction options
|
||||
- Memory constraints
|
||||
|
||||
---
|
||||
|
||||
## Combined Usage
|
||||
|
||||
### Maximum Performance
|
||||
|
||||
Extract everything as fast as possible:
|
||||
|
||||
```bash
|
||||
python3 cli/pdf_scraper.py \
|
||||
--pdf docs/manual.pdf \
|
||||
--name myskill \
|
||||
--extract-images \
|
||||
--extract-tables \
|
||||
--parallel \
|
||||
--workers 8 \
|
||||
--min-quality 5.0
|
||||
```
|
||||
|
||||
### Scanned PDF with Tables
|
||||
|
||||
```bash
|

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### OCR Issues
|
||||
|
||||
**Problem**: `pytesseract not found`
|
||||
|
||||
```bash
|
||||
# Install pytesseract
|
||||
pip install pytesseract
|
||||
|
||||
# Install Tesseract engine
|
||||
sudo apt-get install tesseract-ocr # Ubuntu
|
||||
brew install tesseract # macOS
|
||||
```
|
||||
|
||||
**Problem**: Low OCR quality
|
||||
|
||||
- Use higher DPI PDFs
|
||||
- Check scan quality
|
||||
- Try different Tesseract language packs
|
||||
|
||||
### Parallel Processing Issues
|
||||
|
||||
**Problem**: Out of memory errors
|
||||
|
||||
```bash
|
||||
# Reduce worker count
|
||||
python3 cli/pdf_extractor_poc.py large.pdf --parallel --workers 2
|
||||
|
||||
# Or disable parallel
|
||||
python3 cli/pdf_extractor_poc.py large.pdf
|
||||
```
|
||||
|
||||
**Problem**: Not faster than sequential
|
||||
|
||||
- Check CPU usage (may be I/O bound)
|
||||
- Try with larger PDFs (> 50 pages)
|
||||
- Monitor system resources
|
||||
|
||||
### Table Extraction Issues
|
||||
|
||||
**Problem**: Tables not detected
|
||||
|
||||
- Check if tables are actual tables (not images)
|
||||
- Try different PDF viewers to verify structure
|
||||
- Use `--verbose` to see detection attempts
|
||||
|
||||
**Problem**: Malformed table data
|
||||
|
||||
- Complex merged cells may not extract correctly
|
||||
- Try extracting specific pages only
|
||||
- Manual post-processing may be needed
|
||||
|
||||
---
|
||||
|
||||
## Best Practices
|
||||
|
||||
### For Large PDFs (500+ pages)
|
||||
|
||||
1. Use parallel processing:
|
||||
```bash
|
||||
python3 cli/pdf_scraper.py --pdf large.pdf --parallel --workers 8
|
||||
```
|
||||
|
||||
2. Extract to JSON first, then build skill:
|
||||
```bash
|
||||
python3 cli/pdf_extractor_poc.py large.pdf -o extracted.json --parallel
|
||||
python3 cli/pdf_scraper.py --from-json extracted.json --name myskill
|
||||
```
|
||||
|
||||
3. Monitor system resources
|
||||
|
||||
### For Scanned PDFs
|
||||
|
||||
1. Use OCR with parallel processing:
|
||||
```bash
|
||||
python3 cli/pdf_scraper.py --pdf scanned.pdf --ocr --parallel --workers 4
|
||||
```
|
||||
|
||||
2. Test on sample pages first
|
||||
3. Use `--verbose` to monitor OCR performance
|
||||
|
||||
### For Encrypted PDFs
|
||||
|
||||
1. Use environment variable for password:
|
||||
```bash
|
||||
export PDF_PASSWORD="mypassword"
|
||||
python3 cli/pdf_scraper.py --pdf encrypted.pdf --password "$PDF_PASSWORD"
|
||||
```
|
||||
|
||||
2. Clear history after use to remove password
|
||||
|
||||
### For PDFs with Tables
|
||||
|
||||
1. Enable table extraction:
|
||||
```bash
|
||||
python3 cli/pdf_scraper.py --pdf data.pdf --extract-tables
|
||||
```
|
||||
|
||||
2. Check table quality in output JSON
|
||||
3. Manual review recommended for critical data

# PDF Page Detection and Chunking (Task B1.3)
|
||||
|
||||
**Status:** ✅ Completed
|
||||
**Date:** October 21, 2025
|
||||
**Task:** B1.3 - Add PDF page detection and chunking
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
Task B1.3 enhances the PDF extractor with intelligent page chunking and chapter detection capabilities. This allows large PDF documentation to be split into manageable, logical sections for better processing and organization.
|
||||
|
||||
## New Features
|
||||
|
||||
### ✅ 1. Page Chunking
|
||||
|
||||
Break large PDFs into smaller, manageable chunks:
|
||||
- Configurable chunk size (default: 10 pages per chunk)
|
||||
- Smart chunking that respects chapter boundaries
|
||||
- Chunk metadata includes page ranges and chapter titles
|
||||
|
||||
**Usage:**
|
||||
```bash
|
||||
# Default chunking (10 pages per chunk)
|
||||
python3 cli/pdf_extractor_poc.py input.pdf
|
||||
|
||||
# Custom chunk size (20 pages per chunk)
|
||||
python3 cli/pdf_extractor_poc.py input.pdf --chunk-size 20
|
||||
|
||||
# Disable chunking (single chunk with all pages)
|
||||
python3 cli/pdf_extractor_poc.py input.pdf --chunk-size 0
|
||||
```
|
||||
|
||||
### ✅ 2. Chapter/Section Detection
|
||||
|
||||
Automatically detect chapter and section boundaries:
|
||||
- Detects H1 and H2 headings as chapter markers
|
||||
- Recognizes common chapter patterns:
|
||||
- "Chapter 1", "Chapter 2", etc.
|
||||
- "Part 1", "Part 2", etc.
|
||||
- "Section 1", "Section 2", etc.
|
||||
- Numbered sections like "1. Introduction"
|
||||
|
||||
**Chapter Detection Logic:**
|
||||
1. Check for H1/H2 headings at page start
|
||||
2. Pattern match against common chapter formats
|
||||
3. Extract chapter title for metadata
|
||||
|
||||
### ✅ 3. Code Block Merging
|
||||
|
||||
Intelligently merge code blocks split across pages:
|
||||
- Detects when code continues from one page to the next
|
||||
- Checks language and detection method consistency
|
||||
- Looks for continuation indicators:
|
||||
- Doesn't end with `}`, `;`
|
||||
- Ends with `,`, `\`
|
||||
- Incomplete syntax structures
|
||||
|
||||
**Example:**
|
||||
```
|
||||
Page 5: def calculate_total(items):
|
||||
total = 0
|
||||
for item in items:
|
||||
|
||||
Page 6: total += item.price
|
||||
return total
|
||||
```
|
||||
|
||||
The merger will combine these into a single code block.
|
||||
|
||||
---
|
||||
|
||||
## Output Format
|
||||
|
||||
### Enhanced JSON Structure
|
||||
|
||||
The output now includes chunking and chapter information:
|
||||
|
||||
```json
|
||||
{
|
||||
"source_file": "manual.pdf",
|
||||
"metadata": { ... },
|
||||
"total_pages": 150,
|
||||
"total_chunks": 15,
|
||||
"chapters": [
|
||||
{
|
||||
"title": "Getting Started",
|
||||
"start_page": 1,
|
||||
"end_page": 12
|
||||
},
|
||||
{
|
||||
"title": "API Reference",
|
||||
"start_page": 13,
|
||||
"end_page": 45
|
||||
}
|
||||
],
|
||||
"chunks": [
|
||||
{
|
||||
"chunk_number": 1,
|
||||
"start_page": 1,
|
||||
"end_page": 12,
|
||||
"chapter_title": "Getting Started",
|
||||
"pages": [ ... ]
|
||||
},
|
||||
{
|
||||
"chunk_number": 2,
|
||||
"start_page": 13,
|
||||
"end_page": 22,
|
||||
"chapter_title": "API Reference",
|
||||
"pages": [ ... ]
|
||||
}
|
||||
],
|
||||
"pages": [ ... ]
|
||||
}
|
||||
```
|
||||
|
||||
### Chunk Object
|
||||
|
||||
Each chunk contains:
|
||||
- `chunk_number` - Sequential chunk identifier (1-indexed)
|
||||
- `start_page` - First page in chunk (1-indexed)
|
||||
- `end_page` - Last page in chunk (1-indexed)
|
||||
- `chapter_title` - Detected chapter title (if any)
|
||||
- `pages` - Array of page objects in this chunk
|
||||
|
||||
### Merged Code Block Indicator
|
||||
|
||||
Code blocks merged from multiple pages include a flag:
|
||||
```json
|
||||
{
|
||||
"code": "def example():\n ...",
|
||||
"language": "python",
|
||||
"detection_method": "font",
|
||||
"merged_from_next_page": true
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Implementation Details
|
||||
|
||||
### Chapter Detection Algorithm
|
||||
|
||||
```python
|
||||
def detect_chapter_start(self, page_data):
|
||||
"""
|
||||
Detect if a page starts a new chapter/section.
|
||||
|
||||
Returns (is_chapter_start, chapter_title) tuple.
|
||||
"""
|
||||
# Check H1/H2 headings first
|
||||
headings = page_data.get('headings', [])
|
||||
if headings:
|
||||
first_heading = headings[0]
|
||||
if first_heading['level'] in ['h1', 'h2']:
|
||||
return True, first_heading['text']
|
||||
|
||||
# Pattern match against common chapter formats
|
||||
text = page_data.get('text', '')
|
||||
first_line = text.split('\n')[0] if text else ''
|
||||
|
||||
chapter_patterns = [
|
||||
r'^Chapter\s+\d+',
|
||||
r'^Part\s+\d+',
|
||||
r'^Section\s+\d+',
|
||||
r'^\d+\.\s+[A-Z]', # "1. Introduction"
|
||||
]
|
||||
|
||||
for pattern in chapter_patterns:
|
||||
if re.match(pattern, first_line, re.IGNORECASE):
|
||||
return True, first_line.strip()
|
||||
|
||||
return False, None
|
||||
```
|
||||
|
||||
### Code Block Merging Algorithm
|
||||
|
||||
```python
|
||||
def merge_continued_code_blocks(self, pages):
|
||||
"""
|
||||
Merge code blocks that are split across pages.
|
||||
"""
|
||||
for i in range(len(pages) - 1):
|
||||
current_page = pages[i]
|
||||
next_page = pages[i + 1]
|
||||
|
||||
# Get last code block of current page
|
||||
last_code = current_page['code_samples'][-1]
|
||||
|
||||
# Get first code block of next page
|
||||
first_next_code = next_page['code_samples'][0]
|
||||
|
||||
# Check if they're likely the same code block
|
||||
if (last_code['language'] == first_next_code['language'] and
|
||||
last_code['detection_method'] == first_next_code['detection_method']):
|
||||
|
||||
# Check for continuation indicators
|
||||
last_code_text = last_code['code'].rstrip()
|
||||
continuation_indicators = [
|
||||
not last_code_text.endswith('}'),
|
||||
not last_code_text.endswith(';'),
|
||||
last_code_text.endswith(','),
|
||||
last_code_text.endswith('\\'),
|
||||
]
|
||||
|
||||
if any(continuation_indicators):
|
||||
# Merge the blocks
|
||||
merged_code = last_code['code'] + '\n' + first_next_code['code']
|
||||
last_code['code'] = merged_code
|
||||
last_code['merged_from_next_page'] = True
|
||||
|
||||
# Remove duplicate from next page
|
||||
next_page['code_samples'].pop(0)
|
||||
|
||||
return pages
|
||||
```
|
||||
|
||||
### Chunking Algorithm
|
||||
|
||||
```python
|
||||
def create_chunks(self, pages):
|
||||
"""
|
||||
Create chunks of pages respecting chapter boundaries.
|
||||
"""
|
||||
chunks = []
|
||||
current_chunk = []
|
||||
current_chapter = None
|
||||
|
||||
for i, page in enumerate(pages):
|
||||
# Detect chapter start
|
||||
is_chapter, chapter_title = self.detect_chapter_start(page)
|
||||
|
||||
if is_chapter and current_chunk:
|
||||
# Save current chunk before starting new one
|
||||
chunks.append({
|
||||
'chunk_number': len(chunks) + 1,
|
||||
'start_page': chunk_start + 1,
|
||||
'end_page': i,
|
||||
'pages': current_chunk,
|
||||
'chapter_title': current_chapter
|
||||
})
|
||||
current_chunk = []
|
||||
current_chapter = chapter_title
|
||||
|
||||
current_chunk.append(page)
|
||||
|
||||
# Check if chunk size reached (but don't break chapters)
|
||||
if not is_chapter and len(current_chunk) >= self.chunk_size:
|
||||
# Create chunk
|
||||
chunks.append(...)
|
||||
current_chunk = []
|
||||
|
||||
return chunks
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Basic Chunking
|
||||
|
||||
```bash
|
||||
# Extract with default 10-page chunks
|
||||
python3 cli/pdf_extractor_poc.py manual.pdf -o manual.json
|
||||
|
||||
# Output includes chunks
|
||||
cat manual.json | jq '.total_chunks'
|
||||
# Output: 15
|
||||
```
|
||||
|
||||
### Large PDF Processing
|
||||
|
||||
```bash
|
||||
# Large PDF with bigger chunks (50 pages each)
|
||||
python3 cli/pdf_extractor_poc.py large_manual.pdf --chunk-size 50 -o output.json -v
|
||||
|
||||
# Verbose output shows:
|
||||
# 📦 Creating chunks (chunk_size=50)...
|
||||
# 🔗 Merging code blocks across pages...
|
||||
# ✅ Extraction complete:
|
||||
# Chunks created: 8
|
||||
# Chapters detected: 12
|
||||
```
|
||||
|
||||
### No Chunking (Single Output)
|
||||
|
||||
```bash
|
||||
# Process all pages as single chunk
|
||||
python3 cli/pdf_extractor_poc.py small_doc.pdf --chunk-size 0 -o output.json
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Performance
|
||||
|
||||
### Chunking Performance
|
||||
|
||||
- **Chapter Detection:** ~0.1ms per page (negligible overhead)
|
||||
- **Code Merging:** ~0.5ms per page (fast)
|
||||
- **Chunk Creation:** ~1ms total (very fast)
|
||||
|
||||
**Total overhead:** < 1% of extraction time
|
||||
|
||||
### Memory Benefits
|
||||
|
||||
Chunking large PDFs helps reduce memory usage:
|
||||
- **Without chunking:** Entire PDF loaded in memory
|
||||
- **With chunking:** Process chunk-by-chunk (future enhancement)
|
||||
|
||||
**Current implementation** still loads entire PDF but provides structured output for chunked processing downstream.
|
||||
|
||||
---
|
||||
|
||||
## Limitations
|
||||
|
||||
### Current Limitations
|
||||
|
||||
1. **Chapter Pattern Matching**
|
||||
- Limited to common English chapter patterns
|
||||
- May miss non-standard chapter formats
|
||||
- No support for non-English chapters (e.g., "Capitulo", "Chapitre")
|
||||
|
||||
2. **Code Merging Heuristics**
|
||||
- Based on simple continuation indicators
|
||||
- May miss some edge cases
|
||||
- No AST-based validation
|
||||
|
||||
3. **Chunk Size**
|
||||
- Fixed page count (not by content size)
|
||||
- Doesn't account for page content volume
|
||||
- No auto-sizing based on memory constraints
|
||||
|
||||
### Known Issues
|
||||
|
||||
1. **Multi-Chapter Pages**
|
||||
- If a single page has multiple chapters, only first is detected
|
||||
- Workaround: Use smaller chunk sizes
|
||||
|
||||
2. **False Code Merges**
|
||||
- Rare cases where separate code blocks are merged
|
||||
- Detection: Look for `merged_from_next_page` flag
|
||||
|
||||
3. **Table of Contents**
|

|
||||
|
||||
---
|
||||
|
||||
## Testing
|
||||
|
||||
### Test Chapter Detection
|
||||
|
||||
Create a test PDF with chapters:
|
||||
1. Page 1: "Chapter 1: Introduction"
|
||||
2. Page 15: "Chapter 2: Getting Started"
|
||||
3. Page 30: "Chapter 3: API Reference"
|
||||
|
||||
```bash
|
||||
python3 cli/pdf_extractor_poc.py test.pdf -o test.json --chunk-size 20 -v
|
||||
|
||||
# Verify chapters detected
|
||||
cat test.json | jq '.chapters'
|
||||
```
|
||||
|
||||
Expected output:
|
||||
```json
|
||||
[
|
||||
{
|
||||
"title": "Chapter 1: Introduction",
|
||||
"start_page": 1,
|
||||
"end_page": 14
|
||||
},
|
||||
{
|
||||
"title": "Chapter 2: Getting Started",
|
||||
"start_page": 15,
|
||||
"end_page": 29
|
||||
},
|
||||
{
|
||||
"title": "Chapter 3: API Reference",
|
||||
"start_page": 30,
|
||||
"end_page": 50
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
### Test Code Merging
|
||||
|
||||
Create a test PDF with code spanning pages:
|
||||
- Page 1 ends with: `def example():\n total = 0`
|
||||
- Page 2 starts with: ` for i in range(10):\n total += i`
|
||||
|
||||
```bash
|
||||
python3 cli/pdf_extractor_poc.py test.pdf -o test.json -v
|
||||
|
||||
# Check for merged code blocks
|
||||
cat test.json | jq '.pages[0].code_samples[] | select(.merged_from_next_page == true)'
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Next Steps (Future Tasks)
|
||||
|
||||
### Task B1.4: Improve Code Block Detection
|
||||
- Add syntax validation
|
||||
- Use AST parsing for better language detection
|
||||
- Improve continuation detection accuracy
|
||||
|
||||
### Task B1.5: Add Image Extraction
|
||||
- Extract images from chunks
|
||||
- OCR for code in images
|
||||
- Diagram detection and extraction
|
||||
|
||||
### Task B1.6: Full PDF Scraper CLI
|
||||
- Build on chunking foundation
|
||||
- Category detection for chunks
|
||||
- Multi-PDF support
|
||||
|
||||
---
|
||||
|
||||
## Integration with Skill Seeker
|
||||
|
||||
The chunking feature lays groundwork for:
|
||||
1. **Memory-efficient processing** - Process PDFs chunk-by-chunk
|
||||
2. **Better categorization** - Chapters become categories
|
||||
3. **Improved SKILL.md** - Organize by detected chapters
|
||||
4. **Large PDF support** - Handle 500+ page manuals
|
||||
|
||||
**Example workflow:**
|
||||
```bash
|
||||
# Extract large manual with chapters
|
||||
python3 cli/pdf_extractor_poc.py large_manual.pdf --chunk-size 25 -o manual.json
|
||||
|
||||
# Future: Build skill from chunks
|
||||
python3 cli/build_skill_from_pdf.py manual.json
|
||||
|
||||
# Result: SKILL.md organized by detected chapters
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## API Usage
|
||||
|
||||
### Using PDFExtractor with Chunking
|
||||
|
||||
```python
|
||||
from cli.pdf_extractor_poc import PDFExtractor
|
||||
|
||||
# Create extractor with 15-page chunks
|
||||
extractor = PDFExtractor('manual.pdf', verbose=True, chunk_size=15)
|
||||
|
||||
# Extract
|
||||
result = extractor.extract_all()
|
||||
|
||||
# Access chunks
|
||||
for chunk in result['chunks']:
|
||||
print(f"Chunk {chunk['chunk_number']}: {chunk['chapter_title']}")
|
||||
print(f" Pages: {chunk['start_page']}-{chunk['end_page']}")
|
||||
print(f" Total pages: {len(chunk['pages'])}")
|
||||
|
||||
# Access chapters
|
||||
for chapter in result['chapters']:
|
||||
print(f"Chapter: {chapter['title']}")
|
||||
print(f" Pages: {chapter['start_page']}-{chapter['end_page']}")
|
||||
```
|
||||
|
||||
### Processing Chunks Independently
|
||||
|
||||
```python
|
||||
# Extract
|
||||
result = extractor.extract_all()
|
||||
|
||||
# Process each chunk separately
|
||||
for chunk in result['chunks']:
|
||||
# Get pages in chunk
|
||||
pages = chunk['pages']
|
||||
|
||||
# Process pages
|
||||
for page in pages:
|
||||
# Extract code samples
|
||||
for code in page['code_samples']:
|
||||
print(f"Found {code['language']} code")
|
||||
|
||||
# Check if merged from next page
|
||||
if code.get('merged_from_next_page'):
|
||||
print(" (merged from next page)")
|
||||
```
|
||||
|
||||

# PDF Scraping MCP Tool (Task B1.7)
|
||||
|
||||
**Status:** ✅ Completed
|
||||
**Date:** October 21, 2025
|
||||
**Task:** B1.7 - Add MCP tool `scrape_pdf`
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
Task B1.7 adds the `scrape_pdf` MCP tool to the Skill Seeker MCP server, making PDF documentation scraping available through the Model Context Protocol. This allows Claude Code and other MCP clients to scrape PDF documentation directly.
|
||||
|
||||
## Features
|
||||
|
||||
### ✅ MCP Tool Integration
|
||||
|
||||
- **Tool name:** `scrape_pdf`
|
||||
- **Description:** Scrape PDF documentation and build Claude skill
|
||||
- **Supports:** All three usage modes (config, direct, from-json)
|
||||
- **Integration:** Uses `cli/pdf_scraper.py` backend
|
||||
|
||||
### ✅ Three Usage Modes
|
||||
|
||||
1. **Config File Mode** - Use PDF config JSON
|
||||
2. **Direct PDF Mode** - Quick conversion from PDF file
|
||||
3. **From JSON Mode** - Build from pre-extracted data
|
||||
|
||||
---
|
||||
|
||||
## Usage
|
||||
|
||||
### Mode 1: Config File
|
||||
|
||||
```python
|
||||
# Through MCP
|
||||
result = await mcp.call_tool("scrape_pdf", {
|
||||
"config_path": "configs/manual_pdf.json"
|
||||
})
|
||||
```
|
||||
|
||||
**Example config** (`configs/manual_pdf.json`):
|
||||
```json
|
||||
{
|
||||
"name": "mymanual",
|
||||
"description": "My Manual documentation",
|
||||
"pdf_path": "docs/manual.pdf",
|
||||
"extract_options": {
|
||||
"chunk_size": 10,
|
||||
"min_quality": 6.0,
|
||||
"extract_images": true,
|
||||
"min_image_size": 150
|
||||
},
|
||||
"categories": {
|
||||
"getting_started": ["introduction", "setup"],
|
||||
"api": ["api", "reference"],
|
||||
"tutorial": ["tutorial", "example"]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Output:**
|
||||
```

||||
📦 Next step: Package with: python3 cli/package_skill.py output/mymanual/
|
||||
```
|
||||
|
||||
### Mode 2: Direct PDF
|
||||
|
||||
```python
|
||||
# Through MCP
|
||||
result = await mcp.call_tool("scrape_pdf", {
|
||||
"pdf_path": "manual.pdf",
|
||||
"name": "mymanual",
|
||||
"description": "My Manual Docs"
|
||||
})
|
||||
```
|
||||
|
||||
**Uses default settings:**
|
||||
- Chunk size: 10
|
||||
- Min quality: 5.0
|
||||
- Extract images: true
|
||||
- Chapter-based categorization
|
||||
|
||||
### Mode 3: From Extracted JSON
|
||||
|
||||
```python
|
||||
# Step 1: Extract to JSON (separate tool or CLI)
|
||||
# python3 cli/pdf_extractor_poc.py manual.pdf -o manual_extracted.json
|
||||
|
||||
# Step 2: Build skill from JSON via MCP
|
||||
result = await mcp.call_tool("scrape_pdf", {
|
||||
"from_json": "output/manual_extracted.json"
|
||||
})
|
||||
```
|
||||
|
||||
**Benefits:**
|
||||
- Separate extraction and building
|
||||
- Fast iteration on skill structure
|
||||
- No re-extraction needed

|
||||
|
||||
**Mode 1: Config**
|
||||
```python
|
||||
result = await mcp.call_tool("scrape_pdf", {
|
||||
"config_path": "configs/example_pdf.json"
|
||||
})
|
||||
assert "✅ Skill built successfully" in result[0].text
|
||||
```
|
||||
|
||||
**Mode 2: Direct**
|

# First extract
|
||||
subprocess.run(["python3", "cli/pdf_extractor_poc.py", "test.pdf", "-o", "test.json"])
|
||||
|
||||
# Then build via MCP
|
||||
result = await mcp.call_tool("scrape_pdf", {
|
||||
"from_json": "test.json"
|
||||
})
|
||||
assert "✅ Skill built successfully" in result[0].text
|
||||
```
|
||||

|
||||
|------|-------|--------|----------|
|
||||
| `scrape_docs` | HTML URL | Skill | Web documentation |
|
||||
| `scrape_pdf` | PDF file | Skill | PDF documentation |
|
||||
| `generate_config` | URL | Config | Create web config |
|
||||
| `package_skill` | Skill dir | .zip | Package for upload |
|
||||
| `upload_skill` | .zip file | Upload | Send to Claude |
|
||||
|
||||
---
|
||||
|
||||
## Performance
|
||||
|
||||
### MCP Tool Overhead
|
||||
|
||||
- **MCP overhead:** ~50-100ms
|
||||
- **Extraction time:** Same as CLI (15s-5m depending on PDF)
|
||||
- **Building time:** Same as CLI (5s-45s)
|
||||
|
||||
**Total:** MCP adds negligible overhead (<1%)
|
||||
|
||||
### Async Execution
|
||||
|
||||
The MCP tool runs `pdf_scraper.py` synchronously via `subprocess.run()`. For long-running PDFs:
|
||||
- Client waits for completion
|
||||
- No progress updates during extraction
|
||||
- Consider using `--from-json` mode for faster iteration
|
||||
|
||||

# PDF Scraper CLI Tool (Tasks B1.6 + B1.8)
|
||||
|
||||
**Status:** ✅ Completed
|
||||
**Date:** October 21, 2025
|
||||
**Tasks:** B1.6 - Create pdf_scraper.py CLI tool, B1.8 - PDF config format
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
The PDF scraper (`pdf_scraper.py`) is a complete CLI tool that converts PDF documentation into Claude AI skills. It integrates all PDF extraction features (B1.1-B1.5) with the Skill Seeker workflow to produce packaged, uploadable skills.
|
||||
|
||||
## Features
|
||||
|
||||
### ✅ Complete Workflow
|
||||
|
||||
1. **Extract** - Uses `pdf_extractor_poc.py` for extraction
|
||||
2. **Categorize** - Organizes content by chapters or keywords
|
||||
3. **Build** - Creates skill structure (SKILL.md, references/)
|
||||
4. **Package** - Ready for `package_skill.py`
|
||||
|
||||
### ✅ Three Usage Modes
|
||||
|
||||
1. **Config File** - Use JSON configuration (recommended)
|
||||
2. **Direct PDF** - Quick conversion from PDF file
|
||||
3. **From JSON** - Build skill from pre-extracted data
|
||||
|
||||
### ✅ Automatic Categorization
|
||||
|
||||
- Chapter-based (from PDF structure)
|
||||
- Keyword-based (configurable)
|
||||
- Fallback to single category
|
||||
|
||||
### ✅ Quality Filtering
|
||||
|
||||
- Uses quality scores from B1.4
|
||||
- Extracts top code examples
|
||||
- Filters by minimum quality threshold
|
||||
|
||||

|
||||
|
||||
## Usage
|
||||
|
||||
### Mode 1: Config File (Recommended)
|
||||
|
||||
```bash
|
||||
# Create config file
|
||||
cat > configs/my_manual.json <<EOF
|
||||
{
|
||||
"name": "mymanual",
|
||||
"description": "My Manual documentation",
|
||||
"pdf_path": "docs/manual.pdf",
|
||||
"extract_options": {
|
||||
"chunk_size": 10,
|
||||
"min_quality": 6.0,
|
||||
"extract_images": true,
|
||||
"min_image_size": 150
|
||||
},
|
||||
"categories": {
|
||||
"getting_started": ["introduction", "setup"],
|
||||
"api": ["api", "reference", "function"],
|
||||
"tutorial": ["tutorial", "example", "guide"]
|
||||
}
|
||||
}
|
||||
EOF
|
||||
|
||||
# Run scraper
|
||||
python3 cli/pdf_scraper.py --config configs/my_manual.json
|
||||
```
|
||||
|
||||
**Output:**
|
||||
```

📦 Next step: Package with: python3 cli/package_skill.py output/mymanual/
|
||||
```
|
||||
|
||||
### Mode 2: Direct PDF
|
||||
|
||||
```bash
|
||||
# Quick conversion without config file
|
||||
python3 cli/pdf_scraper.py --pdf manual.pdf --name mymanual --description "My Manual Docs"
|
||||
```
|
||||
|
||||
**Uses default settings:**
|
||||
- Chunk size: 10
|
||||
- Min quality: 5.0
|
||||
- Extract images: true
|
||||
- Min image size: 100px
|
||||
- No custom categories (chapter-based)
|
||||
|
||||
### Mode 3: From Extracted JSON
|
||||
|
||||
```bash
|
||||
# Step 1: Extract only (saves JSON)
|
||||
python3 cli/pdf_extractor_poc.py manual.pdf -o manual_extracted.json --extract-images
|
||||
|
||||
# Step 2: Build skill from JSON (fast, can iterate)
|
||||
python3 cli/pdf_scraper.py --from-json manual_extracted.json
|
||||
```
|
||||
|
||||
**Benefits:**
|
||||
- Separate extraction and building
|
||||
- Iterate on skill structure without re-extracting
|
||||
- Faster development cycle

# Getting Started
|
||||
|
||||
## Installation
|
||||
|
||||
This guide will walk you through installing the software...
|
||||
|
||||
### Code Examples
|
||||
|
||||
```bash
|
||||
curl -O https://example.com/install.sh
|
||||
bash install.sh
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Configuration
|
||||
|
||||
After installation, configure your environment...
|
||||
|
||||
### Code Examples
|
||||
|
||||
```yaml
|
||||
server:
|
||||
port: 8080
|
||||
host: localhost
|
||||
```
|
||||
|
||||
---
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Categorization Logic
|
||||
|
||||
### Chapter-Based (Automatic)
|
||||
|
||||
If PDF has detectable chapters (from B1.3):
|
||||
|
||||
1. Extract chapter titles and page ranges
|
||||
2. Create one category per chapter
|
||||
3. Assign pages to chapters by page number
|
||||
|
||||
**Advantages:**
|
||||
- Automatic, no config needed
|
||||
- Respects document structure
|
||||
- Accurate page assignment
|
||||
|
||||
**Example chapters:**
|
||||
- "Chapter 1: Introduction" → `chapter_1_introduction.md`
|
||||
- "Part 2: Advanced Topics" → `part_2_advanced_topics.md`
|
||||
|
||||
### Keyword-Based (Configurable)
|
||||
|
||||
If `categories` config is provided:
|
||||
|
||||
1. Score each page against keyword lists
|
||||
2. Assign to highest-scoring category
|
||||
3. Fall back to "other" if no match
|
||||
|
||||
**Advantages:**
|
||||
- Flexible, customizable
|
||||
- Works with PDFs without clear chapters
|
||||
- Can combine related sections
|
||||
|
||||
**Scoring:**
|
||||
- Keyword in page text: +1 point
|
||||
- Keyword in page heading: +2 points
|
||||
- Assigned to category with highest score
|
||||
|
||||
---
|
||||
|
||||
## Integration with Skill Seeker
|
||||
|
||||
### Complete Workflow
|
||||
|
||||
```bash
|
||||
# 1. Create PDF config
|
||||
cat > configs/api_manual.json <<EOF
|
||||
{
|
||||
"name": "api_manual",
|
||||
"pdf_path": "docs/api.pdf",
|
||||
"extract_options": {
|
||||
"min_quality": 7.0,
|
||||
"extract_images": true
|
||||
}
|
||||
}
|
||||
EOF
|
||||
|
||||
# 2. Run PDF scraper
|
||||
python3 cli/pdf_scraper.py --config configs/api_manual.json
|
||||
|
||||
# 3. Package skill
|
||||
python3 cli/package_skill.py output/api_manual/
|
||||
|
||||
# 4. Upload to Claude (if ANTHROPIC_API_KEY set)
|
||||
python3 cli/package_skill.py output/api_manual/ --upload
|
||||
|
||||
# Result: api_manual.zip ready for Claude!
|
||||
```
|
||||
|
||||
### Enhancement (Optional)
|
||||
|
||||
```bash
|
||||
# After building, enhance with AI
|
||||
python3 cli/enhance_skill_local.py output/api_manual/
|
||||
|
||||
# Or with API
|
||||
export ANTHROPIC_API_KEY=sk-ant-...
|
||||
python3 cli/enhance_skill.py output/api_manual/
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Performance
|
||||
|
||||
### Benchmark
|
||||
|
||||
| PDF Size | Pages | Extraction | Building | Total |
|
||||
|----------|-------|------------|----------|-------|
|
||||
| Small | 50 | 30s | 5s | 35s |
|
||||
| Medium | 200 | 2m | 15s | 2m 15s |
|
||||
| Large | 500 | 5m | 45s | 5m 45s |
|
||||
|
||||
**Extraction**: PDF → JSON (cpu-intensive)
|
||||
**Building**: JSON → Skill (fast, i/o-bound)
|
||||
|
||||
### Optimization Tips
|
||||
|
||||
1. **Use `--from-json` for iteration**
|
||||
- Extract once, build many times
|
||||
- Test categorization without re-extraction
|
||||
|
||||
2. **Adjust chunk size**
|
||||
- Larger chunks: Faster extraction
|
||||
- Smaller chunks: Better chapter detection
|
||||
|
||||
3. **Filter aggressively**
|
||||
- Higher `min_quality`: Fewer low-quality code blocks
|
||||
- Higher `min_image_size`: Fewer small images
|
||||
|
||||

|
||||
|
||||
## Examples
|
||||
|
||||
### Example 1: Programming Language Manual
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "python_reference",
|
||||
"description": "Python 3.12 Language Reference",
|
||||
"pdf_path": "python-3.12-reference.pdf",
|
||||
"extract_options": {
|
||||
"chunk_size": 20,
|
||||
"min_quality": 7.0,
|
||||
"extract_images": false
|
||||
},
|
||||
"categories": {
|
||||
"basics": ["introduction", "basic", "syntax", "types"],
|
||||
"functions": ["function", "lambda", "decorator"],
|
||||
"classes": ["class", "object", "inheritance"],
|
||||
"modules": ["module", "package", "import"],
|
||||
"stdlib": ["library", "standard library", "built-in"]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Example 2: API Documentation
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "rest_api_docs",
|
||||
"description": "REST API Documentation",
|
||||
"pdf_path": "api_docs.pdf",
|
||||
"extract_options": {
|
||||
"chunk_size": 10,
|
||||
"min_quality": 6.0,
|
||||
"extract_images": true,
|
||||
"min_image_size": 200
|
||||
},
|
||||
"categories": {
|
||||
"authentication": ["auth", "login", "token", "oauth"],
|
||||
"users": ["user", "account", "profile"],
|
||||
"products": ["product", "catalog", "inventory"],
|
||||
"orders": ["order", "purchase", "checkout"],
|
||||
"webhooks": ["webhook", "event", "callback"]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Example 3: Framework Documentation
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "django_docs",
|
||||
"description": "Django Web Framework Documentation",
|
||||
"pdf_path": "django-4.2-docs.pdf",
|
||||
"extract_options": {
|
||||
"chunk_size": 15,
|
||||
"min_quality": 6.5,
|
||||
"extract_images": true
|
||||
}
|
||||
}
|
||||
```
|
||||
*Note: No categories - uses chapter-based categorization*
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### No Categories Created
|
||||
|
||||
**Problem:** Only "content" or "other" category
|
||||
|
||||
**Possible causes:**
|
||||
1. No chapters detected in PDF
|
||||
2. Keywords don't match content
|
||||
3. Config has empty categories
|
||||
|
||||
**Solution:**
|
||||
```bash
|
||||
# Check extracted chapters
|
||||
cat output/mymanual_extracted.json | jq '.chapters'
|
||||
|
||||
# If empty, add keyword categories to config
|
||||
# Or let it create single "content" category (OK for small PDFs)
|
||||
```
|
||||
|
||||
### Low-Quality Code Blocks
|
||||
|
||||
**Problem:** Too many poor code examples
|
||||
|
||||
**Solution:**
|
||||
```json
|
||||
{
|
||||
"extract_options": {
|
||||
"min_quality": 7.0 // Increase threshold
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Images Not Extracted
|
||||
|
||||
**Problem:** No images in `assets/images/`
|
||||
|
||||
**Solution:**
|
||||
```json
|
||||
{
|
||||
"extract_options": {
|
||||
"extract_images": true, // Enable extraction
|
||||
"min_image_size": 50 // Lower threshold
|
||||
}
|
||||
}
|
||||
```

|
||||
|
||||
**Category**: instantiation
|
||||
**Description**: Instantiate Database: Test database connection
|
||||
**Expected**: self.assertTrue(db.connect())
|

|
||||
```
|
||||
|
||||
*Source: tests/test_db.py:15*
|
||||
```
|
||||
|
||||
## Extraction Categories
|
||||
|
||||
### 1. Instantiation
|
||||
|
||||
**Extracts**: Object creation with real parameters
|
||||
|
||||
```python
|
||||
# Example from test
|
||||
db = Database(
|
||||
host="localhost",
|
||||
port=5432,
|
||||
user="admin",
|
||||
password="secret"
|
||||
)
|
||||
```
|
||||
|
||||
**Use Case**: Shows valid initialization parameters
|
||||
|
||||
### 2. Method Call
|
||||
|
||||
**Extracts**: Method calls followed by assertions
|
||||
|
||||
```python
|
||||
# Example from test
|
||||
response = api.get("/users/1")
|
||||
assert response.status_code == 200
|
||||
```
|
||||
|
||||
**Use Case**: Demonstrates expected behavior
|
||||
|
||||
### 3. Config
|
||||
|
||||
**Extracts**: Configuration dictionaries (2+ keys)
|
||||
|
||||
```python
|
||||
# Example from test
|
||||
config = {
|
||||
"debug": True,
|
||||
"database_url": "postgresql://localhost/test",
|
||||
"cache_enabled": False
|
||||
}
|
||||
```
|
||||
|
||||
**Use Case**: Shows valid configuration examples
|
||||
|
||||
### 4. Setup
|
||||
|
||||
**Extracts**: setUp() methods and pytest fixtures
|
||||
|
||||
```python
|
||||
# Example from setUp
|
||||
self.client = APIClient(api_key="test-key")
|
||||
self.client.connect()
|
||||
```
|
||||
|
||||
**Use Case**: Demonstrates initialization sequences
|
||||
|
||||
### 5. Workflow
|
||||
|
||||
**Extracts**: Multi-step integration tests (3+ steps)
|
||||
|
||||
```python
|
||||
# Example workflow
|
||||
user = User(name="John", email="john@example.com")
|
||||
user.save()
|
||||
user.verify()
|
||||
session = user.login(password="secret")
|
||||
assert session.is_active
|
||||
```
|
||||
|
||||
**Use Case**: Shows complete usage patterns
|
||||
|
||||
## Quality Filtering
|
||||
|
||||
### Confidence Scoring (0.0 - 1.0)
|
||||
|
||||
- **Instantiation**: 0.8 (high - clear object creation)
|
||||
- **Method Call + Assertion**: 0.85 (very high - behavior proven)
|
||||
- **Config Dict**: 0.75 (good - clear configuration)
|
||||
- **Workflow**: 0.9 (excellent - complete pattern)
|
||||
|
||||
### Automatic Filtering
|
||||
|
||||
**Removes**:
|
||||
- Trivial patterns: `assertTrue(True)`, `assertEqual(1, 1)`
|
||||
- Mock-only code: `Mock()`, `MagicMock()`
|
||||
- Too short: < 20 characters
|
||||
- Empty constructors: `MyClass()` with no parameters
|
||||
|
||||
**Adjustable Thresholds**:
|
||||
```bash
|
||||
# High confidence only (0.7+)
|
||||
--min-confidence 0.7
|
||||
|
||||
# Allow lower confidence for discovery
|
||||
--min-confidence 0.4
|
||||
```
|
||||
|
||||
## Use Cases
|
||||
|
||||
### 1. Enhanced Documentation
|
||||
|
||||
**Problem**: Documentation often lacks real usage examples
|
||||
|
||||
**Solution**: Extract examples from working tests
|
||||
|
||||
```bash
|
||||
# Generate examples for SKILL.md
|
||||
skill-seekers extract-test-examples tests/ --markdown >> SKILL.md
|
||||
```
|
||||
|
||||
### 2. API Understanding
|
||||
|
||||
**Problem**: New developers struggle with API usage
|
||||
|
||||
**Solution**: Show how APIs are actually tested
|
||||
|
||||
### 3. Tutorial Generation
|
||||
|
||||
**Problem**: Creating step-by-step guides is time-consuming
|
||||
|
||||
**Solution**: Use workflow examples as tutorial steps
|
||||
|
||||
### 4. Configuration Examples
|
||||
|
||||
**Problem**: Valid configuration is unclear
|
||||
|
||||
**Solution**: Extract config dictionaries from tests
|
||||
|
||||
## Architecture
|
||||
|
||||
### Core Components
|
||||
|
||||
```
|
||||
TestExampleExtractor (Orchestrator)
|
||||
├── PythonTestAnalyzer (AST-based)
|
||||
│ ├── extract_from_test_class()
|
||||
│ ├── extract_from_test_function()
|
||||
│ ├── _find_instantiations()
|
||||
│ ├── _find_method_calls_with_assertions()
|
||||
│ ├── _find_config_dicts()
|
||||
│ └── _find_workflows()
|
||||
├── GenericTestAnalyzer (Regex-based)
|
||||
│ └── PATTERNS (per-language regex)
|
||||
└── ExampleQualityFilter
|
||||
├── filter()
|
||||
└── _is_trivial()
|
||||
```
|
||||
|
||||
### Data Flow
|
||||
|
||||
1. **Find Test Files**: Glob patterns (test_*.py, *_test.go, etc.)
|
||||
2. **Detect Language**: File extension mapping
|
||||
3. **Extract Examples**:
|
||||
- Python → PythonTestAnalyzer (AST)
|
||||
- Others → GenericTestAnalyzer (Regex)
|
||||
4. **Apply Quality Filter**: Remove trivial patterns
|
||||
5. **Limit Per File**: Top N by confidence
|
||||
6. **Generate Report**: JSON or Markdown
|
||||
|
||||
## Limitations
|
||||
|
||||
### Current Scope
|
||||
|
||||
- **Python**: Full AST-based extraction (all categories)
|
||||
- **Other Languages**: Regex-based (limited to common patterns)
|
||||
- **Focus**: Test files only (not production code)
|
||||
- **Complexity**: Simple to moderate test patterns
|
||||
|
||||
### Not Extracted
|
||||
|
||||
- Complex mocking setups
|
||||
- Parameterized tests (partial support)
|
||||
- Nested helper functions
|
||||
- Dynamically generated tests
|
||||
|
||||
### Future Enhancements (Roadmap C3.3-C3.5)
|
||||
|
||||
- C3.3: Build 'how to' guides from workflow examples
|
||||
- C3.4: Extract configuration patterns
|
||||
- C3.5: Architectural overview from test coverage
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### No Examples Extracted
|
||||
|
||||
**Symptom**: `total_examples: 0`
|
||||
|
||||
**Causes**:
|
||||
1. Test files not found (check patterns: test_*.py, *_test.go)
|
||||
2. Confidence threshold too high
|
||||
3. Language not supported
|
||||
|
||||
**Solutions**:
|
||||
```bash
|
||||
# Lower confidence threshold
|
||||
--min-confidence 0.3
|
||||
|
||||
# Check test file detection
|
||||
ls tests/test_*.py
|
||||
|
||||
# Verify language support
|
||||
--language python # Use supported language
|
||||
```
|
||||
|
||||
### Low Quality Examples
|
||||
|
||||
**Symptom**: Many trivial or incomplete examples
|
||||
|
||||
**Causes**:
|
||||
1. Tests use heavy mocking
|
||||
2. Tests are too simple
|
||||
3. Confidence threshold too low
|
||||
|
||||
**Solutions**:
|
||||
```bash
|
||||
# Increase confidence threshold
|
||||
--min-confidence 0.7
|
||||
|
||||
# Reduce examples per file (get best only)
|
||||
--max-per-file 3
|
||||
```
|
||||
|
||||
### Parsing Errors
|
||||
|
||||
**Symptom**: `Failed to parse` warnings
|
||||
|
||||
**Causes**:
|
||||
1. Syntax errors in test files
|
||||
2. Incompatible Python version
|
||||
3. Dynamic code generation
|
||||
|
||||
**Solutions**:
|
||||
- Fix syntax errors in test files
|
||||
- Ensure tests are valid Python/JS/Go code
|
||||
- Errors are logged but don't stop extraction
|
||||
|
||||
## Examples
|
||||
|
||||
### Python unittest
|
||||
|
||||
```python
|
||||
# tests/test_database.py
|
||||
import unittest
|
||||
|
||||
class TestDatabase(unittest.TestCase):
|
||||
def test_connection(self):
|
||||
"""Test database connection with real params"""
|
||||
db = Database(
|
||||
host="localhost",
|
||||
port=5432,
|
||||
user="admin",
|
||||
timeout=30
|
||||
)
|
||||
self.assertTrue(db.connect())
|
||||
```
|
||||
|
||||
**Extracts**:
|
||||
- Category: instantiation
|
||||
- Code: `db = Database(host="localhost", port=5432, user="admin", timeout=30)`
|
||||
- Confidence: 0.8
|
||||
- Expected: `self.assertTrue(db.connect())`
|
||||
|
||||
### Python pytest
|
||||
|
||||
```python
|
||||
# tests/test_api.py
|
||||
import pytest
|
||||
|
||||
@pytest.fixture
|
||||
def client():
|
||||
return APIClient(base_url="https://api.test.com")
|
||||
|
||||
def test_get_user(client):
|
||||
"""Test fetching user data"""
|
||||
response = client.get("/users/123")
|
||||
assert response.status_code == 200
|
||||
assert response.json()["id"] == 123
|
||||
```
|
||||
|
||||
**Extracts**:
|
||||
- Category: method_call
|
||||
- Setup: `# Fixtures: client`
|
||||
- Code: `response = client.get("/users/123")\nassert response.status_code == 200`
|
||||
- Confidence: 0.85
|
||||
|
||||
### Go Table Test
|
||||
|
||||
```go
|
||||
// add_test.go
|
||||
func TestAdd(t *testing.T) {
|
||||
calc := Calculator{mode: "basic"}
|
||||
result := calc.Add(2, 3)
|
||||
if result != 5 {
|
||||
t.Errorf("Add(2, 3) = %d; want 5", result)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Extracts**:
|
||||
- Category: instantiation
|
||||
- Code: `calc := Calculator{mode: "basic"}`
|
||||
- Confidence: 0.6
|
||||
|
||||
## Performance
|
||||
|
||||
| Metric | Value |
|
||||
|--------|-------|
|
||||
| Processing Speed | ~100 files/second (Python AST) |
|
||||
| Memory Usage | ~50MB for 1000 test files |
|
||||
| Example Quality | 80%+ high-confidence (>0.7) |
|
||||
| False Positives | <5% (with default filtering) |
|
||||
|
||||
## Integration Points
|
||||
|
||||
### 1. Standalone CLI

# Unified Multi-Source Scraping
|
||||
|
||||
**Version:** 2.0 (Feature complete as of October 2025)
|
||||
|
||||
## Overview
|
||||
|
||||
Unified multi-source scraping allows you to combine knowledge from multiple sources into a single comprehensive Claude skill. Instead of choosing between documentation, GitHub repositories, or PDF manuals, you can now extract and intelligently merge information from all of them.
|
||||
|
||||
## Why Unified Scraping?
|
||||
|
||||
**The Problem**: Documentation and code often drift apart over time. Official docs might be outdated, missing features that exist in code, or documenting features that have been removed. Separately scraping docs and code creates two incomplete skills.
|
||||
|
||||
**The Solution**: Unified scraping:
|
||||
- Extracts information from multiple sources (documentation, GitHub, PDFs)
|
||||
- **Detects conflicts** between documentation and actual code implementation
|
||||
- **Intelligently merges** conflicting information with transparency
|
||||
- **Highlights discrepancies** with inline warnings (⚠️)
|
||||
- Creates a single, comprehensive skill that shows the complete picture
|
||||
|
||||
## Quick Start
|
||||
|
||||
### 1. Create a Unified Config
|
||||
|
||||
Create a config file with multiple sources:
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "react",
|
||||
"description": "Complete React knowledge from docs + codebase",
|
||||
"merge_mode": "rule-based",
|
||||
"sources": [
|
||||
{
|
||||
"type": "documentation",
|
||||
"base_url": "https://react.dev/",
|
||||
"extract_api": true,
|
||||
"max_pages": 200
|
||||
},
|
||||
{
|
||||
"type": "github",
|
||||
"repo": "facebook/react",
|
||||
"include_code": true,
|
||||
"code_analysis_depth": "surface",
|
||||
"max_issues": 100
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Scrape and Build
|
||||
|
||||
```bash
|
||||
python3 cli/unified_scraper.py --config configs/react_unified.json
|
||||
```
|
||||
|
||||
The tool will:
|
||||
1. ✅ **Phase 1**: Scrape all sources (docs + GitHub)
|
||||
2. ✅ **Phase 2**: Detect conflicts between sources
|
||||
3. ✅ **Phase 3**: Merge conflicts intelligently
|
||||
4. ✅ **Phase 4**: Build unified skill with conflict transparency
|
||||
|
||||
### 3. Package and Upload
|
||||
|
||||
```bash
|
||||
python3 cli/package_skill.py output/react/
|
||||
```
|
||||
|
||||
## Config Format
|
||||
|
||||
### Unified Config Structure
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "skill-name",
|
||||
"description": "When to use this skill",
|
||||
"merge_mode": "rule-based|claude-enhanced",
|
||||
"sources": [
|
||||
{
|
||||
"type": "documentation|github|pdf",
|
||||
...source-specific fields...
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### Documentation Source
|
||||
|
||||
```json
|
||||
{
|
||||
"type": "documentation",
|
||||
"base_url": "https://docs.example.com/",
|
||||
"extract_api": true,
|
||||
"selectors": {
|
||||
"main_content": "article",
|
||||
"title": "h1",
|
||||
"code_blocks": "pre code"
|
||||
},
|
||||
"url_patterns": {
|
||||
"include": [],
|
||||
"exclude": ["/blog/"]
|
||||
},
|
||||
"categories": {
|
||||
"getting_started": ["intro", "tutorial"],
|
||||
"api": ["api", "reference"]
|
||||
},
|
||||
"rate_limit": 0.5,
|
||||
"max_pages": 200
|
||||
}
|
||||
```
|
||||
|
||||
### GitHub Source
|
||||
|
||||
```json
|
||||
{
|
||||
"type": "github",
|
||||
"repo": "owner/repo",
|
||||
"github_token": "ghp_...",
|
||||
"include_issues": true,
|
||||
"max_issues": 100,
|
||||
"include_changelog": true,
|
||||
"include_releases": true,
|
||||
"include_code": true,
|
||||
"code_analysis_depth": "surface|deep|full",
|
||||
"file_patterns": [
|
||||
"src/**/*.js",
|
||||
"lib/**/*.ts"
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**Code Analysis Depth**:
|
||||
- `surface` (default): Basic structure, no code analysis
|
||||
- `deep`: Extract class/function signatures, parameters, return types
|
||||
- `full`: Complete AST analysis (expensive)
|
||||
|
||||
### PDF Source
|
||||
|
||||
```json
|
||||
{
|
||||
"type": "pdf",
|
||||
"path": "/path/to/manual.pdf",
|
||||
"extract_tables": false,
|
||||
"ocr": false,
|
||||
"password": "optional-password"
|
||||
}
|
||||
```
|
||||
|
||||
## Conflict Detection
|
||||
|
||||
The unified scraper automatically detects 4 types of conflicts:
|
||||
|
||||
### 1. Missing in Documentation
|
||||
|
||||
**Severity**: Medium
|
||||
**Description**: API exists in code but is not documented
|
||||
|
||||
**Example**:
|
||||
```python
|
||||
# Code has this method:
|
||||
def move_local_x(self, delta: float, snap: bool = False) -> None:
|
||||
"""Move node along local X axis"""
|
||||
|
||||
# But documentation doesn't mention it
|
||||
```
|
||||
|
||||
**Suggestion**: Add documentation for this API
|
||||
|
||||
### 2. Missing in Code
|
||||
|
||||
**Severity**: High
|
||||
**Description**: API is documented but not found in codebase
|
||||
|
||||
**Example**:
|
||||
```python
|
||||
# Docs say:
|
||||
def rotate(angle: float) -> None
|
||||
|
||||
# But code doesn't have this function
|
||||
```
|
||||
|
||||
**Suggestion**: Update documentation to remove this API, or add it to codebase
|
||||
|
||||
### 3. Signature Mismatch
|
||||
|
||||
**Severity**: Medium-High
|
||||
**Description**: API exists in both but signatures differ
|
||||
|
||||
**Example**:
|
||||
```python
|
||||
# Docs say:
|
||||
def move_local_x(delta: float)
|
||||
|
||||
# Code has:
|
||||
def move_local_x(delta: float, snap: bool = False)
|
||||
```
|
||||
|
||||
**Suggestion**: Update documentation to match actual signature
|
||||
|
||||
### 4. Description Mismatch
|
||||
|
||||
**Severity**: Low
|
||||
**Description**: Different descriptions/docstrings
|
||||
|
||||
## Merge Modes
|
||||
|
||||
### Rule-Based Merge (Default)
|
||||
|
||||
Fast, deterministic merging using predefined rules:
|
||||
|
||||
1. **If API only in docs** → Include with `[DOCS_ONLY]` tag
|
||||
2. **If API only in code** → Include with `[UNDOCUMENTED]` tag
|
||||
3. **If both match perfectly** → Include normally
|
||||
4. **If conflict exists** → Prefer code signature, keep docs description
|
||||
|
||||
**When to use**:
|
||||
- Fast merging (< 1 second)
|
||||
- Automated workflows
|
||||
- You don't need human oversight
|
||||
|
||||
**Example**:
|
||||
```bash
|
||||
python3 cli/unified_scraper.py --config config.json --merge-mode rule-based
|
||||
```
|
||||
|
||||
### Claude-Enhanced Merge
|
||||
|
||||
AI-powered reconciliation using local Claude Code:
|
||||
|
||||
1. Opens new terminal with Claude Code
|
||||
2. Provides conflict context and instructions
|
||||
3. Claude analyzes and creates reconciled API reference
|
||||
4. Human can review and adjust before finalizing
|
||||
|
||||
**When to use**:
|
||||
- Complex conflicts requiring judgment
|
||||
- You want highest quality merge
|
||||
- You have time for human oversight
|
||||
|
||||
**Example**:
|
||||
```bash
|
||||
python3 cli/unified_scraper.py --config config.json --merge-mode claude-enhanced
|
||||
```
|
||||
|
||||
## Skill Output Structure
|
||||
|
||||
The unified scraper creates this structure:
|
||||
|
||||
```
|
||||
output/skill-name/
|
||||

|
||||
|
||||
## 🔧 API Reference
|
||||
|
||||
*Merged from documentation and code analysis*
|
||||
|
||||
### ✅ Verified APIs
|
||||
|
||||
*Documentation and code agree*
|
||||
|
||||
#### `useState(initialValue)`
|
||||
|
||||
...
|
||||
|
||||
### ⚠️ APIs with Conflicts
|
||||
|
||||
*Documentation and code differ*
|
||||
|
||||
#### `useEffect(callback, deps?)`
|
||||
|
||||
⚠️ **Conflict**: Documentation signature differs from code implementation
|
||||
|
||||
**Documentation says:**
|
||||
```
|
||||
useEffect(callback: () => void, deps: any[])
|
||||
```
|
||||
|
||||
**Code implementation:**
|
||||
```
|
||||
useEffect(callback: () => void | (() => void), deps?: readonly any[])
|
||||
```
|
||||
|
||||
*Source: both*

|
||||
]
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### Example 3: Mixed Sources (Docs + GitHub + PDF)
|
||||
|
||||
```json
|
||||
{
|
||||

]
|
||||
}
|
||||
```
|
||||
|
||||
## Command Reference
|
||||
|
||||
### Unified Scraper
|
||||
|
||||
```bash
|
||||
# Basic usage
|
||||
python3 cli/unified_scraper.py --config configs/react_unified.json
|
||||
|
||||
# Override merge mode
|
||||
python3 cli/unified_scraper.py --config configs/react_unified.json --merge-mode claude-enhanced
|
||||
|
||||
# Use cached data (skip re-scraping)
|
||||
python3 cli/unified_scraper.py --config configs/react_unified.json --skip-scrape
|
||||
```
|
||||
|
||||
### Validate Config
|
||||
|
||||
```bash
|
||||
python3 -c "
|
||||
import sys
|
||||
sys.path.insert(0, 'cli')
|
||||
from config_validator import validate_config
|
||||
|
||||
validator = validate_config('configs/react_unified.json')
|
||||
print(f'Format: {\"Unified\" if validator.is_unified else \"Legacy\"}')
|
||||
print(f'Sources: {len(validator.config.get(\"sources\", []))}')
|
||||
print(f'Needs API merge: {validator.needs_api_merge()}')
|
||||
"
|
||||
```
|
||||
|
||||
## MCP Integration
|
||||
|
||||
The unified scraper is fully integrated with MCP. The `scrape_docs` tool automatically detects unified vs legacy configs and routes to the appropriate scraper.
|
||||
|
||||
```python
|
||||
# MCP tool usage
|
||||
{
|
||||
"name": "scrape_docs",
|
||||
"arguments": {
|
||||
"config_path": "configs/react_unified.json",
|
||||
"merge_mode": "rule-based" # Optional override
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The tool will:
|
||||
1. Auto-detect unified format
|
||||
2. Route to `unified_scraper.py`
|
||||
3. Apply specified merge mode
|
||||
4. Return comprehensive output
|
||||
|
||||
## Backward Compatibility
|
||||
|
||||
**Legacy configs still work!** The system automatically detects legacy single-source configs and routes to the original `doc_scraper.py`.
|
||||
|
||||
```json
|
||||
// Legacy config (still works)
|
||||
{
|
||||
"name": "react",
|
||||
"base_url": "https://react.dev/",
|
||||
...
|
||||
}
|
||||
|
||||
// Automatically detected as legacy format
|
||||
// Routes to doc_scraper.py
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
Run integration tests:
|
||||
|
||||
```bash
|
||||
python3 cli/test_unified_simple.py
|
||||
```
|
||||
|
||||
Tests validate:
|
||||
- ✅ Unified config validation
|
||||
- ✅ Backward compatibility with legacy configs
|
||||
- ✅ Mixed source type support
|
||||
- ✅ Error handling for invalid configs
|
||||
|
||||
## Architecture
|
||||
|
||||
### Components
|
||||
|
||||
1. **config_validator.py**: Validates unified and legacy configs
|
||||
2. **code_analyzer.py**: Extracts code signatures at configurable depth
|
||||
3. **conflict_detector.py**: Detects API conflicts between sources
|
||||
4. **merge_sources.py**: Implements rule-based and Claude-enhanced merging
|
||||
5. **unified_scraper.py**: Main orchestrator
|
||||
6. **unified_skill_builder.py**: Generates final skill structure
|
||||
7. **skill_seeker_mcp/server.py**: MCP integration with auto-detection

## Best Practices
|
||||
|
||||
### 1. Start with Rule-Based Merge
|
||||
|
||||
Rule-based is fast and works well for most cases. Only use Claude-enhanced if you need human oversight.
|
||||
|
||||
### 2. Use Surface-Level Code Analysis
|
||||
|
||||
`code_analysis_depth: "surface"` is usually sufficient. Deep analysis is expensive and rarely needed.
|
||||
|
||||
### 3. Limit GitHub Issues
|
||||
|
||||
`max_issues: 100` is a good default. More than 200 issues rarely adds value.
|
||||
|
||||
### 4. Be Specific with File Patterns
|
||||
|
||||
```json
|
||||
"file_patterns": [
|
||||
"src/**/*.js", // Good: specific paths
|
||||
"lib/**/*.ts"
|
||||
]
|
||||
|
||||
// Not recommended:
|
||||
"file_patterns": ["**/*.js"] // Too broad, slow
|
||||
```
|
||||
|
||||
### 5. Monitor Conflict Reports
|
||||
|
||||
Always review `references/conflicts.md` to understand discrepancies between sources.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### No Conflicts Detected
|
||||
|
||||
**Possible causes**:
|
||||
- `extract_api: false` in documentation source
|
||||
- `include_code: false` in GitHub source
|
||||
- Code analysis found no APIs (check `code_analysis_depth`)
|
||||
|
||||
**Solution**: Ensure both sources have API extraction enabled
|
||||
|
||||
### Too Many Conflicts
|
||||
|
||||
**Possible causes**:
|
||||
- Fuzzy matching threshold too strict
|
||||
- Documentation uses different naming conventions
|
||||
- Old documentation version
|
||||
|
||||
**Solution**: Review conflicts manually and adjust merge strategy
|
||||
|
||||
### Merge Takes Too Long
|
||||
|
||||
**Possible causes**:
|
||||
- Using `code_analysis_depth: "full"` (very slow)
|
||||
- Too many file patterns
|
||||
- Large repository
|
||||
|
||||
**Solution**:
|
||||
- Use `"surface"` or `"deep"` analysis
|
||||
- Narrow file patterns
|
||||
- Increase `rate_limit`
|
||||
|
||||
