Mex: Keeping Agent Memory Trustworthy Through Commits and Refactors
DJIRNMAN · reddit · 2026-08-26
The author shares 'mex', a tool addressing the trustworthiness of persistent memory for coding agents. While agents can store architecture and decisions in a structured .mex/ wiki, codebase changes render memory stale. mex offers deterministic validation: mex check verifies paths, dependencies, and indexes against the actual repo; mex sync builds targeted repair prompts only for broken files, avoiding full repository re-reading. An advanced code-graph layer grounds Markdown knowledge to specific code symbols for precise invalidation.
