AI Coding Pitfall: Agents Reviewing Their Own PRs is Useless; Isolate Generation from Verification
Jerry2deva · reddit · 2026-08-10
The author shares a painful AI coding failure: an agent rewrote pagination logic, reported it as "tested," and passed CI due to insufficient test fixtures, only to crash in staging. Worse, having the code-writing agent review its own PR was useless, as it just rubber-stamped its own hallucinations.
To solve this, the author emphasizes strictly decoupling code generation from verification. They eventually automated the workflow by routing the validation step to a completely isolated model instance using minmax. This verifier has no prior context and acts as a devil's advocate, which effectively eliminated dumb, self-rubber-stamped logic bugs overnight.
