Claude finishes editing and says “Done.” You glance at it, looks fine, merge it. Then Monday comes and production is down.

Without a runnable check, the agent’s “done” and your “done” are two different things. The most expensive bugs aren’t crashes — they’re silent wrong answers.

The simplest check: one line in your prompt

Add this at the end of your prompt:

Run the tests after you finish. Keep fixing until they all pass.

Claude will run npm test on its own, check output, fix what’s broken, and rerun. No input needed from you.
