bus factor = how many people it takes to cover more than half the commits (6 months). 1 is a solo project; higher means the work is spread across a team. top-author share is the single busiest author's slice of those commits.

why it's a big deal

  • It gives coding agents persistent memory across sessions, so context from past work is captured and injected into new sessions instead of being lost when a session ends.
  • It targets developers using Claude Code and similar agent harnesses, and also claims support for OpenCode, Claude Desktop, and other gateways.
  • Its progressive-disclosure retrieval returns compact search indexes first and fetches full observation details only for filtered IDs, cutting the tokens spent on recall.

under the hood

  • Written in JavaScript, it hooks into five Claude Code lifecycle events (SessionStart, UserPromptSubmit, PostToolUse, Stop, SessionEnd) to capture tool usage and generate semantic summaries automatically.
  • A local worker service on port 37777 exposes an HTTP API and web viewer, backed by SQLite with FTS5 full-text search and a Chroma vector store for hybrid semantic and keyword search.
  • It installs via npx or a plugin marketplace, requires Node 20 plus auto-installed Bun and uv, ships four MCP search tools, and is licensed Apache-2.0 to allow embedding in other tools.
