Confirm all section headers match your team's PR template. Verify the How to Test steps accurately reproduce the change in a fresh local environment before posting.
Works best on diffs under 400 lines. Very large PRs should be split by logical change before pasting. Output quality degrades if the diff lacks context — include your ticket or issue number in the prompt. Does not replace meaningful commit messages in the diff itself.
