This is a local SQLite knowledge base that persists across Claude sessions. It exposes MCP tools for storing facts (atomic knowledge snippets), resources (cached file/URL content with staleness tracking), skills (markdown procedural docs), and execution logs (command history). The setup prompt analyzes your project and seeds initial context, then agents can submit_facts, search_facts, add_resources with refresh instructions, and create_skill documents that live in your IDE's prompt directory. Useful when you want Claude to remember project specifics, API patterns, or build procedures without re-explaining every conversation. Includes a file watcher that syncs skill markdown edits and a maintenance worker for keeping cached resources fresh.
