Cortex Plugin Overview

This plugin provides Claude Code with persistent, self-evolving memory across sessions by mining durable lessons from conversation turns. It stores these lessons as human-readable markdown files in a local Obsidian vault and assembles relevant context briefings automatically at session start. It requires no cloud services or API keys, ensuring local-first operation and no vendor lock-in. Use it to maintain project knowledge, conventions, and fixes without re-explaining in each session.
