Unified Multi-Source Scraping

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 Official docs might be outdated, missing features that exist in code, or documenting features that have been removed.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:

{
  "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

python3 cli/unified_scraper.py --config configs/react_unified.json

The tool will:

1. ✅ Phase 1: Scrape all sources (docs + GitHub + PDF + local)
2. ✅ Phase 2: Detect conflicts between sources
3. ✅ Phase 3: Merge conflicts intelligently
4. ✅ Phase 4: Build unified skill with conflict transparency
5. ✅ Phase 5: Apply enhancement workflows (optional)

3. Package and Upload

python3 cli/package_skill.py output/react/

Config Format

Unified Config Structure

{
  "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

{
  "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

{
  "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

{
  "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:

# 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:

# 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:

# 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:

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:

python3 cli/unified_scraper.py --config config.json --merge-mode claude-enhanced

Skill Output Structure

The unified scraper creates this structure:

output/skill-name/
├── SKILL.md                     # Main skill file with merged APIs

Workflow Configuration in JSON

Define workflows directly in your unified config:

{
  "name": "react-complete",
  "description": "React with security focus",
  "merge_mode": "claude-enhanced",
  "workflows": ["security-focus"],
  "workflow_stages": [
    {
      "name": "cleanup",
      "prompt": "Remove boilerplate and standardize formatting"
    }
  ],
  "workflow_vars": {
    "focus_area": "security",
    "detail_level": "comprehensive"
  },
  "sources": [
    {"type": "documentation", "base_url": "https://react.dev/"},
    {"type": "github", "repo": "facebook/react"}
  ]
}

Priority: CLI flags override config values.

Validate Config

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.

# 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.

// 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:

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

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

"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

Future Enhancements

Planned features:

• Automated conflict resolution strategies
• Conflict trend analysis across versions
• Multi-version comparison (docs v1 vs v2)
• Custom merge rules DSL
• Conflict confidence scores
