Ask for the check and the evidence together: "Write and run a Playwright check in Agent Browser that saves the display name, reloads, and asserts it persisted. Record the run with captions and show me the script and results."

Teach a Common Loop about your repository: "Update this PR review Loop to check CSV imports for duplicate customer rows and interrupted uploads. Run the import tests and report the exact failing case."

PR review keeps one reusable task per pull request. When the author pushes a new revision, the next review already knows what it found last time.
