What they did
A developer building an add-on for the Chrome browser set up Claude Code to check its own work. After each change, the agent runs the automatic tests, loads the add-on in Chrome and takes a screenshot. It then fixes any failures before handing the work back.
How it went
The author says failed runs he used to watch over now fix themselves before he sees them. He estimates roughly 3 out of 4 of his "why is this broken" moments are gone.
Try it yourself with Claude Code
For every change you make to [project, e.g. my Chrome extension], verify it yourself before reporting back. First run the test suite with [test command]. Then load the extension in Chrome and take a screenshot of [the page or popup to check]. If a test fails or the screenshot looks wrong, fix the problem and repeat. Only report back once tests pass and the screenshot matches what I asked for. Include the final screenshot and a short list of what you fixed. Do not commit or push anything without my approval.
Swap the highlighted [parts] for your own details.
