Adds a 5-level hierarchical memory store to Claude that persists across sessions and syncs across devices. You get 13 MCP tools for reading, writing, and searching a SQLite-backed knowledge tree where Level 1 loads one-line summaries (~5k tokens for 300+ entries) and deeper levels drill down on demand. Built for project-based AI work: automatic session capture, Haiku background checkpoints that extract decisions and write handoff notes, and a load_project() call that briefs the agent in ~3000 tokens on stack, bugs, roadmap, and where you left off yesterday. Ships with 21 versioned skills that define agent behavior patterns and a TypeScript SDK if you want to embed the store directly into your own tooling.
