Open-source Mex makes coding-agent markdown context files self-sustaining

DJIRNMAN · reddit · 2026-09-03

A developer shares Mex, an open-source project that lets coding agents maintain their own markdown context (CLAUDE.md, runbooks, decision logs) instead of letting it rot. The agent detects changes, updates affected canonical records, appends decision-log entries, and reports which context it used. Open questions: what deserves durable memory, preventing agents from reinforcing wrong assumptions, and resolving code-vs-docs contradictions.
