# Rabby Yarn v4 Commit Check

Use this workflow whenever a task in the Rabby repository will create a commit, amend a commit, create a merge commit, or push a branch that should already include committed work.

## Required Check

Before running `git commit`, `git commit --amend`, or completing a merge commit, run these commands from the repository root:

```bash
yarn
yarn check
```

Treat the sequence as `yarn && yarn check`: only run `yarn check` after `yarn` exits successfully.

## Commit Rules

- Do not commit if `yarn` or `yarn check` exits non-zero.
- If `yarn` changes tracked dependency files, inspect the diff and include only intentional changes.
- If the failure appears unrelated to the current edit, report the exact failing command and the relevant error output before deciding whether to proceed.
- Do not substitute `npm install`, `npm run check`, `yarn lint`, or `yarn typecheck` for the required sequence unless the user explicitly redirects the workflow.
- After committing or pushing, report the commit hash and the validation commands that passed.
