README.md
CTX — Cross-Session Memory for Claude Code
CTX gives Claude Code persistent memory across sessions. It injects relevant past decisions, docs, and context into every prompt automatically via three retrieval layers:
- G1 (time) — recent git commit decisions, ranked by BM25 relevance to the current prompt
- G2 (space) — BM25 search over project docs and code files
- CM (chat) — semantic search over past conversation summaries (optional vec-daemon)
Install
pip install ctx-retriever
ctx-install
Or via Claude Code plugin (this package):
/plugin install ctx@jaytoone
The Setup hook installs dependencies and wires hooks automatically. Restart Claude Code after install.
How it works
CTX runs as Claude Code hooks. On every prompt, it retrieves the top-k relevant memories and injects them as additionalContext so Claude sees your project history without you having to re-explain it.
