Open Pull Request

Opens a draft PR from the current branch following Storybook conventions.

Workflow

1. Gather context

Run in parallel: git status, git diff, git log --oneline <base>...HEAD (after step 2), git branch -vv.

Push first if needed: git push -u origin HEAD.

2. Detect base branch

git fetch origin
bash .agents/skills/open-pr/scripts/detect-base-branch.sh

Detects base in order: tracked upstream → reflog checkout source → closest origin/* ancestor (fewest commits from branch tip to HEAD). Supports telescoped/stacked PRs off feature branches, not only next/main. Skips branches at the same commit as HEAD. Tie-break: feature branch over trunk, then next over main. Falls back to next. Tell the user the result.

3. Ask for labels

Use AskQuestion for three questions. Options from .github/PULL_REQUEST_TEMPLATE.md:

Verify the available labels with the PR template.

4. Draft title and body

Title: [Area]: [Description] — see the pr skill for format and examples.

Body: Read .github/PULL_REQUEST_TEMPLATE.md. Copy it exactly (keep all HTML comments). Fill in:

• Closes # when an issue is linked
• What I did
• Testing checkboxes and mandatory manual-testing steps (or state why none is needed)
• Documentation checkboxes when applicable
• Leave maintainer checklist items unchecked

5. Create the PR

gh pr create \
  --draft \
  --base "<detected-base>" \
  --title "<Area>: <Description>" \
  --body "$(cat <<'EOF'
<FILLED_TEMPLATE>
EOF
)" \
  --assignee @me \
  --label "<type>,<ci>,<qa>"

6. Report and offer canary

Share the PR URL. Then AskQuestion: "Do you want to create a canary release for this PR?"

• Yes — run /canary <PR_NUMBER> and report workflow status
• No — stop

Notes

• Always draft; always assign @me.
• For canary details after publishing, see the canary skill.
