Show GN: CTX: Memory Between Claude Code Sessions — Install via pip install or /plugin install

Claude Code loses context when a session ends, and CTX compensates for this with hooks.

On execution, it automatically injects three types of context within 1ms at the UserPromptSubmit event.

• G1: A decision timeline based on git log that restores why a decision was made yesterday.
• G2: BM25 code/document search that automatically injects relevant files.
• CM: Looks up a past conversation vault using SQLite FTS5 and optional vector search.

The measured results presented are as follows.

• Memory recall accuracy: 0.880
• 95% Wilson CI: [0.762, 0.944]
• Baseline (none): 0.00
• Real-world utilization rate based on 10,000+ turns: 39.6%

The setup assumes no LLM calls, no cloud, and fully local operation.

Installation is offered via two paths.

• pip install ctx-retriever && ctx-install
• /plugin install ctx@jaytoone within Claude Code
