An open-source MCP server and Claude Code plugin that gives your agent a memory for your corrections. Approve, edit or reject a draft and it saves your one-line reason in a local Postgres + pgvector (PGlite). Before the next draft it recalls your rules and the closest past corrections, and the plugin's hooks add them to your prompts on their own, so the agent can't forget to check. Works in Cursor and Claude Desktop too. MIT, nothing to host, plus a browser demo.
