Phase 3: Conflict Detection System ✅ - Created conflict_detector.py (500+ lines) - Detects 4 conflict types: * missing_in_docs - API in code but not documented * missing_in_code - Documented API doesn't exist * signature_mismatch - Different parameters/types * description_mismatch - Docs vs code comments differ - Fuzzy matching for similar names - Severity classification (low/medium/high) - Generates detailed conflict reports Phase 4: Rule-Based Merger ✅ - Fast, deterministic merging rules - 4 rules for handling conflicts: 1. Docs only → Include with [DOCS_ONLY] tag 2. Code only → Include with [UNDOCUMENTED] tag 3. Perfect match → Include normally 4. Conflict → Prefer code signature, keep docs description - Generates unified API reference - Summary statistics (matched, conflicts, etc.) Phase 5: Claude-Enhanced Merger ✅ - AI-powered conflict reconciliation - Opens Claude Code in new terminal - Provides merge context and instructions - Creates workspace with conflicts.json - Waits for human-supervised merge - Falls back to rule-based if needed Testing: ✅ Conflict detector finds 5 conflicts in test data ✅ Rule-based merger successfully merges 5 APIs ✅ Proper handling of docs_only vs code_only ✅ JSON serialization works correctly Next: Orchestrator to tie everything together 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Conflict Detector for Multi-Source Skills
|
|
|
|
Detects conflicts between documentation and code:
|
|
- missing_in_docs: API exists in code but not documented
|
|
- missing_in_code: API documented but doesn't exist in code
|
|
- signature_mismatch: Different parameters/types between docs and code
|
|
- description_mismatch: Docs say one thing, code comments say another
|
|
|
|
Used by unified scraper to identify discrepancies before merging.
