Scraping Guide

Skill Seekers v3.1.0
Complete guide to all scraping options

---

Overview

Skill Seekers can extract knowledge from four types of sources:

Source	Command	Best For
Documentation	create <url>	Web docs, tutorials, API refs
GitHub	create <repo>	Source code, issues, releases
PDF	create <file.pdf>	Manuals, papers, reports
Local	create <./path>	Your projects, internal code

---

Documentation Scraping

Basic Usage

# Auto-detect and scrape
skill-seekers create https://docs.react.dev/

# With custom name
skill-seekers create https://docs.react.dev/ --name react-docs

# With description
skill-seekers create https://docs.react.dev/ \
  --description "React JavaScript library documentation"

Using Preset Configs

# List available presets
skill-seekers estimate --all

# Use preset
skill-seekers create --config react
skill-seekers create --config django
skill-seekers create --config fastapi

Available presets: See configs/ directory in repository.

Custom Configuration

# Create config file
cat > configs/my-docs.json << 'EOF'
{
  "name": "my-framework",
  "base_url": "https://docs.example.com/",
  "description": "My framework documentation",
  "max_pages": 200,
  "rate_limit": 0.5,
  "selectors": {
    "main_content": "article",
    "title": "h1"
  },
  "url_patterns": {
    "include": ["/docs/", "/api/"],
    "exclude": ["/blog/", "/search"]
  }
}
EOF

# Use config
skill-seekers create --config configs/my-docs.json

See Config Format for all options.

Advanced Options

# Limit pages (for testing)
skill-seekers create <url> --max-pages 50

# Adjust rate limit
skill-seekers create <url> --rate-limit 1.0

# Parallel workers (faster)
skill-seekers create <url> --workers 5 --async

# Dry run (preview)
skill-seekers create <url> --dry-run

# Resume interrupted
skill-seekers create <url> --resume

# Fresh start (ignore cache)
skill-seekers create <url> --fresh

---

GitHub Repository Scraping

Basic Usage

# By repo name
skill-seekers create facebook/react

# With explicit flag
skill-seekers github --repo facebook/react

# With custom name
skill-seekers github --repo facebook/react --name react-source

With GitHub Token

# Set token for higher rate limits
export GITHUB_TOKEN=ghp_...

# Use token
skill-seekers github --repo facebook/react

Benefits of token:

• 5000 requests/hour vs 60
• Access to private repos
• Higher GraphQL limits

What Gets Extracted

Data	Default	Flag to Disable
Source code	✅	--scrape-only
README	✅	-
Issues	✅	--no-issues
Releases	✅	--no-releases
Changelog	✅	--no-changelog

Control What to Fetch

# Skip issues (faster)
skill-seekers github --repo facebook/react --no-issues

# Limit issues
skill-seekers github --repo facebook/react --max-issues 50

# Scrape only (no build)
skill-seekers github --repo facebook/react --scrape-only

# Non-interactive (CI/CD)
skill-seekers github --repo facebook/react --non-interactive

---

PDF Extraction

Basic Usage

# Direct file
skill-seekers create manual.pdf --name product-manual

# With explicit command
skill-seekers pdf --pdf manual.pdf --name docs

OCR for Scanned PDFs

# Enable OCR
skill-seekers pdf --pdf scanned.pdf --enable-ocr

Requirements:

pip install skill-seekers[pdf-ocr]
# Also requires: tesseract-ocr (system package)

Password-Protected PDFs

# In config file
{
  "name": "secure-docs",
  "pdf_path": "protected.pdf",
  "password": "secret123"
}

Page Range

# Extract specific pages (via config)
{
  "pdf_path": "manual.pdf",
  "page_range": [1, 100]
}

---

Local Codebase Analysis

Basic Usage

# Current directory
skill-seekers create .

# Specific directory
skill-seekers create ./my-project

# With explicit command
skill-seekers analyze --directory ./my-project

Analysis Presets

# Quick analysis (1-2 min)
skill-seekers analyze --directory ./my-project --preset quick

# Standard analysis (5-10 min) - default
skill-seekers analyze --directory ./my-project --preset standard

# Comprehensive (20-60 min)
skill-seekers analyze --directory ./my-project --preset comprehensive

Common Scraping Patterns

Pattern 1: Test First

# Dry run to preview
skill-seekers create <source> --dry-run

# Small test scrape
skill-seekers create <source> --max-pages 10

# Full scrape
skill-seekers create <source>

Pattern 2: Iterative Development

# Scrape without enhancement (fast)
skill-seekers create <source> --enhance-level 0

# Review output
ls output/my-skill/
cat output/my-skill/SKILL.md

# Enhance later
skill-seekers enhance output/my-skill/

Pattern 3: Parallel Processing

# Fast async scraping
skill-seekers create <url> --async --workers 5

# Even faster (be careful with rate limits)
skill-seekers create <url> --async --workers 10 --rate-limit 0.2

Pattern 4: Resume Capability

# Start scraping
skill-seekers create <source>
# ...interrupted...

# Resume later
skill-seekers resume --list
skill-seekers resume <job-id>

Troubleshooting Scraping

"No content extracted"

Problem: Wrong CSS selectors

Solution:

# Find correct selectors
curl -s <url> | grep -i 'article\|main\|content'

# Update config
{
  "selectors": {
    "main_content": "div.content"  // or "article", "main", etc.
  }
}

"Rate limit exceeded"

Problem: Too many requests

Solution:

# Slow down
skill-seekers create <url> --rate-limit 2.0

# Or use GitHub token for GitHub repos
export GITHUB_TOKEN=ghp_...

"Too many pages"

Problem: Site is larger than expected

Solution:

# Estimate first
skill-seekers estimate configs/my-config.json

# Limit pages
skill-seekers create <url> --max-pages 100

# Adjust URL patterns
{
  "url_patterns": {
    "exclude": ["/blog/", "/archive/", "/search"]
  }
}

"Memory error"

Problem: Site too large for memory

Solution:

# Use streaming mode
skill-seekers create <url> --streaming

# Or smaller chunks
skill-seekers create <url> --chunk-tokens 500

Performance Tips

Tip	Command	Impact
Use presets	--config react	Faster setup
Async mode	--async --workers 5	3-5x faster
Skip enhancement	--enhance-level 0	Skip 60 sec
Use cache	--skip-scrape	Instant rebuild
Resume	--resume	Continue interrupted
