Auth, libraries, documentation, rate limiting all working 3. **Crawler Engine** - Job queue, GitHub crawler, docs scraper, parsers ready 4. **Database** - Schema with full-text search ready 5. **Docker Compose** - Full dev environment in one command 6. **Rate Limiting** - Redis-backed, tiered limits active globally ### Testing Scenarios - User registration and login ✅ - Library search (no data yet, returns empty) - Documentation retrieval (no data yet, returns empty) - MCP tools callable (return proper errors for missing data) - API rate limiting working with headers ✅ - Job queue accepting and processing crawl jobs ✅ - Crawling real repositories from GitHub ✅ - Parsing markdown and extracting code examples ✅ ## 🔧 Next Immediate Steps ### For Testing (Today) 1. Run: `docker-compose -f docker-compose.dev.yml up` 2. Follow TESTING.md for verification procedures 3. Test all API endpoints 4. Verify MCP server communication ### For Development (Next Session) 1. **Phase 5**: Dashboard & authentication pages 2. **Phase 6**: Initial data seeding & testing 3. **Phase 7+**: Production deployment & launch ## 📊 Code Metrics ### Lines of Code -
