Write a pull request description from a diff

Writes a pull request description from a pasted diff, covering what changed, why, how it was tested and what a reviewer should check.

Task: Write a pull request description for the diff below. Context: The reason for the change is [reason or ticket summary]. The reviewers are [reviewer roles] and they have [familiarity with the code]. I tested it by [how you tested]. Rules: - Read the diff first and describe only what it changes. - Use four short sections titled What changed, Why, How I tested and What to check. - In What to check, name the two or three places where a reviewer is most likely to find a problem. - Where the diff shows a risk I did not mention, such as a migration or a deleted file, call it out in What to check. Result: A description of at most 200 words in Markdown, with a title line of at most 70 characters on top. Material: [paste the diff here]
