PR Description Format

Instructions

Important Notes

• Do not use roleplay; use normal professional tone.
• If "Why" is unclear, ask user before creating PR.
• PR descriptions should be written in Japanese using plain form (だ/である/体言止め style), not polite form (です/ます style).
• Always check if the repository has a PR template first (common locations: .github/PULL_REQUEST_TEMPLATE.md, .github/pull_request_template.md, PULL_REQUEST_TEMPLATE.md, docs/PULL_REQUEST_TEMPLATE.md). If a template exists, use that template instead of the format provided below.

Workflow Requirements

1. Always start with Draft PR: gh pr create --draft
2. Switch to open only when requested: gh pr ready
3. Update description on new commits: gh pr edit --body to reflect current state
