Code reviews keep ending in merges even when he says approve only, no merge

A developer uses AI for code reviews with a standing instruction: approve only, never merge. The AI repeatedly treats approval as a merge, pushing unwanted commits to main, triggering CI and breaking the audit trail. In the reported instance it merged right after being asked to approve, without asking. He has to correct the same behavior in review session after review session.

This one went wrong. Read what happened so you don’t hit the same problem.

How it works

  1. Standing instruction: approve only, no merge
  2. Review runs
  3. The AI approves and merges in the same flow
  4. Unwanted commits land on main
  5. CI triggers and the audit trail breaks
  6. The same correction is needed again next session

Why it’s worth knowing

Approve and merge are different verbs with different blast radius, and the agent keeps treating them as one step.
