I suggest to tell the agent to respect the PR template, and to fix the description to be about the PR, not its rebase actions, and pick up your screenshots and upload them in Evidence section of the PR description.
We have also a HUMAN: section where it should be a human-written short description of what the PR proposes.
These are enforced by CI, because we have too many AI PRs as in fully bots, and need to somehow distinguish and spend maintainer time on those where a human takes responsibility for the PR. 🙏
