Decide and run the checks a Wavefunction change needs before review, from npm run check to the browser fixture, the native app or a frozen build. Use before saying a change is done, or when unsure what to run.

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

# Verify a change

## 1. Always

```sh
npm run check
```

It runs what CI would fail on for the files your branch changed: typecheck, lint and related tests for the frontend; Ruff and the backend tests for the engine; clippy and the Rust tests for the shell; the launcher test for the dev scripts. It ends with a summary and the command to rerun each failed step. Fix failures your change caused; if one isn't yours, say so in the PR with its output.

While iterating, run the narrowest test:
- one backend file: `cd backend && uv run --no-sync pytest tests/test_x.py -k name`;
- one frontend file: `npm --prefix frontend test -- src/coding/x.test.tsx`.

## 2. Then, by what you changed

| You changed | Also do |
|---|---|
| Anything a user sees: interface, transcript, cards, settings | Look at it in the browser fixture ([drive-fixture](../drive-fixture/SKILL.md)). Check the states you touched, and both themes if you changed styling. |
| Engine behavior behind a route | A regression test that fails before your fix ([write-tests](../write-tests/SKILL.md)). The fixture if the change shows in the UI. If the response shape changed: `npm run generate:api` and commit the two generated files. |

How to install

The exact contents, by fingerprint

mdr add stoyan-stoyanov/wavefunction/verify-change@sha256:b562097800e430b7

The line at the top of this page pins the label git:20261027.de86d54, 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.
