Let the PR run through review and fix cycles.

/ultrafix is ProPR's stronger correction loop for pull requests that need more than one small follow-up. It alternates AI review and implementation passes, waits for the branch to be ready between steps, and stops at the target score, the cycle limit, or a human stop signal.

Feature overview

One command. Every pass stays in the thread.

This run starts with a human command, turns review findings into a follow-up commit, checks the branch again, and leaves the final merge with the maintainer.

One PR command

Comment /ultrafix when the branch needs an automated cleanup loop. ProPR starts with review unless unprocessed AI review comments are already waiting, in which case it starts by fixing them.

Configurable target

Set the desired score, maximum cycles, pause, and review model with /ultrafix goal=8 max=5 pause=60 model=<model-id>, or use the configured defaults.

Visible stop control

The visible ultrafix PR label controls the loop. Remove it and the loop stops after the current cycle completes.

Review, fix, wait, repeat.

Review the current diff

ProPR runs the read-only /review path and posts structured AI review comments with findings and a Score: N/10.

Apply pending findings

The fix step gathers unprocessed AI review comments, applies the selected feedback in an isolated worktree, and marks those review comments as handled.

Wait for readiness

Before continuing, ProPR waits for required checks, the configured pause, and PR inactivity. The next cycle starts only after the branch is ready.

Stop at the boundary

The loop ends when the review score reaches the goal, the maximum cycle count is exhausted, or someone removes the ultrafix label.

  • Best for cleanup passes

    Reach for Ultrafix when the PR needs repeated review-fix pressure; a single direct change belongs in a normal PR comment.

  • Works with review scoring

    Ultrafix reads the latest valid Score: N/10 from AI review comments to decide whether the loop has hit its target.

  • Keeps branch history intact

    Fixes land as follow-up commits on the same PR branch, so reviewers can inspect each pass in normal GitHub history.

  • Records the loop

    Loop state, completed actions, review counts, fix counts, final score, and completion reason stay attached to the ProPR task history.

Review stops after the critique.

Review is read-only. It posts the findings, score, model details, and next-step guidance without changing the branch.

Ultrafix turns the critique into a loop.

/ultrafix chains review and fix until it reaches the configured stopping condition. It is the automated version of review, select feedback, fix, and review again.
