Pull Request Workflow

This skill covers two tasks: (1) writing a high-quality PR description, and (2) handling review comments on an existing PR.

1. Writing the PR description

Always follow the repository PR template at .github/pull_request_template.md. Keep its exact structure and headings. Fill every section:

### Motivation & Context

Explain why the change is needed: the problem it solves and the scenario it contributes to. Describe the net change relative to main — this is implied, so do not spell out "vs main" explicitly.
