Iterate on a PR without leaving GitHub. A plain comment requests another implementation pass. /review gets an AI critique, and /fix applies the findings you keep. Branch updates and model switches run from the same thread.
ProPR applies the request on the same branch
Plain comments request follow-up work. Slash commands trigger specific actions. ProPR posts every result on the same pull request, with task links and commit details.
Plain commentDescribe what's wrong and what you expect. ProPR turns it into a focused task on the same branch. Line-level review comments and screenshots travel with it. The issue-to-pull-request guide shows where this comment loop starts, from the first label on the issue.
/reviewProPR posts numbered merge blockers (F1), optional suggestions (S1), and a score without touching the code. Name several models, /review <model-a> <model-b>, for independent reviews side by side.
/fixApplies the pending merge blockers in one follow-up pass; /fix all takes every suggestion too. Each review ends with a copyable line such as /fix F20 S3 S5: delete the IDs you don't want and post.
/ultrafixAlternates review and fix until the PR hits the target score or the cycle limit.
/mergeMerges the base branch into the PR branch and resolves conflicts in an isolated task. You merge the PR in GitHub.
/switchSwitch the model for future follow-ups, with optional instructions in the same comment.
A concrete change request gets another commit on the same PR. Update a stale or conflicted branch from the same conversation. For repeated cleanup, Ultrafix chains review and fix cycles inside the GitHub PR loop.
