Team memory for engineers and their AI agents. Lives in your repo. Shared through Git.
mex is a repository-local knowledge system for AI coding agents that turns codebase discoveries into connected Markdown documentation and a code graph. It helps agents and developers retain architectural decisions, conventions, edge cases, and project context across coding sessions while detecting documentation affected by code changes. The catalogue skills and instructions are add-ons for using mex with coding agents.
