Design for extending Claude agent system with semantic search:
- Two indexes: personal (state files) + external docs
- ChromaDB + sentence-transformers stack
- rag-search skill with search.py CLI
- Daily systemd timer for index refresh
- Ralph loop implementation with Haiku/Sonnet delegation
Added future considerations (fc-043 to fc-046):
- Auto-sync on tool version change
- Broad doc indexing
- K8s deployment
- Query caching
