Claude Code App QA Checklist

1. Review everything the agent changed since your last read. Agents are confident about wrong things too — the final diff review is yours.
2. Hunt for invented content. Seeded demo data, sample testimonials, example.com links, lorem ipsum — agents fill gaps with plausible fiction, and shipping it is a trust problem.
3. Read the generated tests, then run them on a clean clone. Confirm they assert real behavior, and that the suite is green outside your working directory.
4. Grep for hardcoded secrets and localhost URLs. Both the working tree and git history; rotate anything that was ever committed.
5. Make one real purchase on the live app. Real card, then refund yourself — success page, receipt email, account state.
6. Fail a payment on purpose. A declined card needs a clear message and a retry path.
7. Verify webhooks against the live endpoint. Watch one fire in the payment dashboard, and know what happens when one is missed.
8. Run the full auth loop. Sign up, log in, log out, reset — with the reset email landing somewhere outside your own domain.
9. Check empty states as a brand-new user. Agents test the happy path with seeded data; your users start with nothing.
10. Break things and read the error states. Failed fetches, bad input, missing records — no stack traces, no dead ends.
11. Visit a bad URL and hard-refresh every route. A branded 404 and no blank screens on deep-link refresh.
12. Sweep the console on every page. Zero red errors shipped.
13. Test at 375px wide. Phones are where your first real users will be.
14. Set meta titles, descriptions, and the OG preview. Check the card by pasting your URL into a chat.
15. Make the trust pages true. Refund, contact, privacy — written by you, not autocompleted, and matching what you actually do.
16. Scan AI-drafted copy for claim risk. Generated marketing text trends confident; cut guarantees and numbers you cannot produce evidence for.
17. Rehearse the rollback and write the runbook. A one-command revert, a tested backup, and who watches errors and payments for the first 48 hours.

Checkboxes are for this visit only — nothing is stored, tracked, or sent anywhere.
