Full Report
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.
