Turns a correction or a repeated mistake into the strongest structure that prevents it, and proves it catches the mistake. Use when the owner says "don't do that again", "remember this", "you keep doing X", or a review finds the same problem twice.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Learn from a mistake

## 1. Name the mistake

Write the mistake as a check: "a list command prints the id before the name", not "be careful with list output". Done when a script could, in principle, detect it.

## 2. Pick the strongest structure that holds it

In this order, take the first that works:

1. **A type** the compiler rejects.
2. **A lint rule** in `.oxlintrc.json`.
3. **A test** that scans the code or the command tree, like `src/lib/root-options.test.ts`, which checks cli-core's argv scan agrees with commander.
4. **A script check** in `.agents/scripts/` (verify, a hook).
5. **A review check** in `.agents/checks/`, for judgment a script can't make.
6. **A line in `AGENTS.md` or a skill**, only if nothing above can hold it.

A rule already written down that still got broken skips straight to 1–4. Done when you can say why the stronger options don't fit.

## 3. Prove it catches the mistake

Make the mistake on purpose. The new structure must fail on it. Remove it: it passes. Run `npm run verify`. Done when you have seen both.

## 4. Delete what it replaces

How to install

The exact contents, by fingerprint

mdr add doist/todoist-cli/learn@sha256:f6c8a8b60800d239

The line at the top of this page pins the label git:20261105.4b96b9d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
