- find_path: BFS traversal to trace relationship chains between two files (max N hops)
- get_file_signatures: lightweight context mode returning just function/type names
- db.find_path(): bidirectional BFS with shortest-path tracking
- db.get_all_files(): list all files with docs and staleness
- db.get_file_signatures(): return functions list without full doc payload
Inspired by Octocode's GraphRAG path-finding pattern.
Addresses Mike/Dmitry feedback on usable roll-up summaries.
- SQLite backend with file/repo/relationship entities
- tree-sitter Go AST parser for deterministic import detection
- Ollama doc generation with concurrent batch processing
- MCP server (FastMCP) for Claude Code integration
- Merge simulation with staleness cascade
- Lazy refresh for stale relationship and repo docs
- CLAUDE.md for agent context
