# PR Fixer

> Use the PR Fixer Expert to repair review findings, CI failures, and merge conflicts on a pull request or merge request.

## PR Fixer

PR Fixer owns the mechanical follow-up after a pull request or merge request is opened. It responds to review findings, diagnoses and fixes CI failures, resolves unambiguous merge conflicts, and explains the changes it makes. It never merges the change; a human owns the final merge decision.

PR Fixer is for existing changes created without PR Author—for example, changes opened by a human or another coding tool. It gives teams a repair loop for those changes without requiring PR Author to have created them.

* **Best for**: Changes created without PR Author that need review feedback addressed, CI repaired, or merge conflicts resolved.
* **How to use**: Start a session with PR Fixer and provide a pull request or merge request URL, or comment `cosmos fix` when configured. It monitors the change, applies safe fixes, and asks for human judgment when intent is ambiguous.
