# 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/`
|
||||
