The AI that wrote your code shouldn't be the one that checks it.
A plain-English way to review what your AI builds before it reaches a customer. For founders and operators who ship real software with Claude Code and can't read every line.
FIX FIRSTReview of "add a cancel button"
- Cancel stops the subscription but the confirmation email is never sent.The send error is caught and ignored.
- Customers who signed up before this change can't cancel at all.Older accounts are missing the field the button checks.
- The new tests only check that the button exists.Nothing tests that billing actually stops.
SHIP
A fresh reviewer looked hard and found nothing serious.
FIX FIRST
Real problems a customer would hit. Send them back, then review again.
STOP
It could lose money, leak data, or destroy data. Don't merge it.
Why a second reviewer
By the end of a session, the AI that built a feature has written the plan, the code, the tests and the summary. Every signal it sees came from itself. A reviewer that starts from nothing, assumes the work is wrong, and is only allowed to report, catches what the builder can't.
The guide explains the whole approach in about ten minutes.
