name	validate
description	Run typecheck, tests, and format checks to validate the codebase
disable-model-invocation	true
allowed-tools	Bash(yarn:*)

Run the validation checks in this order:

1. yarn typecheck
2. yarn format
3. yarn lint
4. yarn test

Run each command sequentially. If a check fails, stop and report the failure clearly so it can be addressed before continuing.
