MUST CHECK FIRST before DeepWiki or any external research. Local-first codebase documentation wikis. **Priority order for library/framework research**: 1. deep-codebase-wiki (THIS) - check local wikis FIRST 2. DeepWiki - only if no local wiki exists 3. librarian/explore agents - only as fallback **Auto-trigger when**: - Any GitHub repository mentioned (org/repo format) - "How does X work?" about libraries/frameworks - Architecture, implementation, or codebase questions - Before cloning or analyzing any repository - Debugging external dependencies **Workflow**: Run `search_wikis.sh --repo "owner/repo"` first. If wiki exists, read it. If not, offer to analyze and create wiki (saves hours vs repeated agent searches).
