index1

AI memory system for coding agents with BM25 + vector hybrid search. Provides 6 MCP tools for intelligent code/doc search and cognitive fact recording.

What it does

• Dual memory: corpus (code index) + cognition (episodic facts)
• Hybrid search: BM25 full-text + vector semantic search with RRF fusion
• Structure-aware chunking: Markdown, Python, Rust, JavaScript, plain text
• MCP Server: 6 tools (recall, learn, read, status, reindex, config)
• CJK optimized: Chinese/Japanese/Korean query detection with dynamic weight tuning
• Built-in ONNX embedding: Vector search works out of the box, no Ollama required
• Graceful degradation: Works without any embedding service (BM25-only mode)
