Copilot Coding Agent

Body

I've noticed that when Copilot Coding Agent is posting replies/comments in PRs, or updating the PR description, it will post broken image URLs. You can see this on nwalters512/cookbook#195 (comment). Here's a screenshot for posterity:

The URLs it uses are like https://github.com/user-attachments/assets/fixed-light-mode.png and https://github.com/user-attachments/assets/fixed-dark-mode.png. A working URL looks like https://github.com/user-attachments/assets/55310844-d275-425f-b85e-426b23f6673d.

There seems to be another failure mode as well: sometimes it will post what look to be valid URLs (e.g. https://github.com/user-attachments/assets/8f3e5c7d-1f47-4e56-9a63-d1e5e8e2c7e0, but that 404s if I hit it directly, and the Markdown that's ultimately rendered doesn't use a https://private-user-images.githubusercontent.com/... src like working images do. An example of that can be seen in nwalters512/cookbook#195 (comment) (the PR description) at the time of writing. Again, a screenshot:

Is this an AI-generated slop response? That URL/repo doesn't exist, and I already included all that information in my discussion post here.

It's not helpful or productive. If you want to pass off AI writing as your own, at least verify it for correctness and make sure it adds something to the discussion.
