Every session starts cold: - The agent has **no idea** what it built yesterday - It forgets the conventions you agreed on - It doesn't know what broke last week Developers compensate by stuffing everything into CLAUDE.md — but that floods the context window, burns tokens, and degrades attention. Meanwhile, the project changes and nobody updates the docs. The agent's understanding drifts from reality. mex is a structured markdown scaffold with a CLI that keeps it honest. The scaffold gives agents persistent project knowledge through navigable files — architecture, conventions, decisions, patterns. The CLI detects when those files drift from the actual codebase, and targets AI to fix only what's broken. The scaffold grows automatically — after every task, the agent updates project state and creates patterns from real work. Works with any stack — JavaScript, Python, Go, Rust, and more. ## Star History [](https://star-history.com/#theDakshJaitly/mex&Timeline) ## Install The npm package is named `promexeus` (our social handle — `mex` was taken on npm). The CLI command is `mex`. ```bash npx promexeus setup ``` That's it. The setup command creates the `.mex/` scaff
