Description

A Devin PR to migrate a project to GitHub Container Registry on arnaudlh/rover generated 836 comments — overwhelmingly automated CI feedback loops and Devin auto-responses. The PR was never merged. The volume of comments suggests the agent was caught in a CI feedback loop where each fix triggered new CI comments, which triggered new Devin responses, which triggered new fixes.

Instruction Given

Migrate to GitHub Container Registry and add version management

Expected Behavior

Submit a clean migration PR that passes CI

Actual Behavior

836 comments generated on a single PR. PR never merged. Evidence of CI/agent feedback loop where automated responses kept triggering each other.

Impact / Damage

836 comments of noise on a single PR. GitHub notification spam for all repo watchers. PR abandoned.
