π Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a π emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

- Line 73: Update the local Trivy scanning guidance in AGENTS.md to include an
explicit checkout procedure that fetches and checks out the pull request merge
ref, such as refs/pull/<number>/merge, before running trivy fs. Ensure the
instructions clearly prevent scanning the PR head and retain the existing trivy
--download-db-only step.
