rag

Complete RAG (Retrieval-Augmented Generation) system for OpenClaw. Indexes chat sessions, workspace code, documentation, and skills into a local ChromaDB for semantic search. Enables finding past solutions, code patterns, and decisions instantly. Uses local embeddings (all-MiniLM-L6-v2) with no API keys required. Automatically ingests and updates the knowledge base from ~/.openclaw/agents/main/sessions and workspace files.
