What I do

• Validate changes locally.
• Push the current branch (handles unset upstream).
• Detect the PR for the current branch.
• Regenerate the PR body from .github/PULL_REQUEST_TEMPLATE.md using the current main...HEAD diff.
• Update the PR body using gh pr update (fallback to gh api).

When to use me

Use this when you already have a PR open and need to refresh its description to match the latest branch changes.

Process

1. Run task validate
2. Collect context:
   • git diff main...HEAD --stat
   • git diff main...HEAD
   • git log main...HEAD --oneline
3. Push current branch:
   • If upstream is not set: git push -u origin HEAD
   • Otherwise: git push
4. Detect PR:
   • Prefer: gh pr view "$(git rev-parse --abbrev-ref HEAD)" --json number,title,url
   • Fallback: gh pr list --head "$(git rev-parse --abbrev-ref HEAD)" --json number,title,url
5. Generate updated PR body (based on .github/PULL_REQUEST_TEMPLATE.md) and fill:
   • Proposed changes: bullets derived from main...HEAD diff (group by area; reference key paths)
   • Testing: include task validate
   • Migration steps (if any)
   • Screenshots placeholders
   • Types of changes: mark what applies
   • Checklist: mark what is true
6. Update PR body:
   • Prefer:

gh pr edit <PR_NUMBER> --body "$(cat <<'EOF'
<filled template body>
EOF
)"

• Fallback:

owner="$(gh repo view --json owner --jq '.owner.login')"
repo="$(gh repo view --json name --jq '.name')"
gh api "repos/${owner}/${repo}/pulls/<PR_NUMBER>" \
  --method PATCH \
  --field body="$(cat <<'EOF'
<filled template body>
EOF
)"
