A note on a diff line gives ProPR the file and line too.

ProPR starts the follow-up

The agent runs in an isolated workspace with the PR conversation, diff and line context.

A follow-up run on the pull request: read the PR comment about the phone layout, move the summary below the form, run the checkout tests

One more commit on the PR

ProPR commits the change to the same branch, so reviewers see one more normal commit in the same thread, and replies with links to the task, the commit and an undo. Looks good? Merge it. Went the wrong way? Revert it.

✅ Follow-up complete. Extracted the database connection string into a utility file and added a 3-retry backoff for timeouts.

The undo link’s preview: the merge commit becomes the new head and the follow-up commit after it is removed
Revert previews exactly which commit leaves the branch.

What you get

Each comment becomes one more commit on the same PR branch, with a reply that links the task, the commit and an undo.
