ralph-knowledge

Semantic search over a personal knowledge corpus using SQLite + sqlite-vec for local embeddings, exposing a stdio MCP server to Claude Code. Version 0.1.49. Indexes markdown roots (defaults to `../../thoughts`). Supports multi-root indexing, gitignore-style ignore patterns, layered configuration (CLI, env vars, config file), and hybrid search with two-tiered retrieval tools (`knowledge_search` and `knowledge_recall`). Ships TypeScript types and provides a reindex CLI. Differentiated by local-only, file-based vector search with no external API dependencies, configurable memory tiers (doc, raw, reflection, wiki), and role-based retrieval policies. Releases appear to be early-stage (pre-1.0) with active development.
