Cortex Plugin

Knowledge & Memory

Persistent, self-evolving memory plugin for Claude Code. Background miner extracts durable lessons (decisions, conventions, bug fixes) from completed sessions via Claude Haiku, stores them as human-readable markdown in an Obsidian vault, and assembles query-tailored context briefings at session start. Local-first, no cloud, no API keys. Self-healing install via uv bootstrap shim, /cortex-doctor preflight, graceful FTS-only degraded mode when claude CLI missing. MIT.
