CTX — Cross-session Memory for Claude Code

Adds CTX to the Developer Productivity section.

What it does:

• Injects G1 (git decision timeline), G2 (BM25 code/doc search), and CM (chat memory vault) before each Claude Code prompt
• Memory recall: 0.88 [0.762, 0.944] vs 0.00 baseline (MAB N=50, Wilson CI)
• Real-world utility: 39.6% of injected items cited by Claude (10,000+ turns measured)
• <1ms, no LLM calls, fully local

Install:

/plugin install ctx@jaytoone

or

pip install ctx-retriever && ctx-install
