Create Draft PR

Create a concise, reviewer-friendly draft PR from the current branch.

Dynamic Context

• Current branch: !git branch --show-current
• Commits: !git log trunk..HEAD --format="%h %s" --reverse 2>/dev/null || echo "No commits ahead of trunk"
• Diff stat: !git diff trunk...HEAD --stat 2>/dev/null
• Uncommitted changes: !git status --short
• Existing changelogs: !git diff trunk...HEAD --name-only -- '*/changelog/*' 2>/dev/null
• PR template: !cat .github/PULL_REQUEST_TEMPLATE.md

Procedure

1. Preflight and Analyze

Verify from dynamic context: not on trunk (stop if so), commits exist ahead of trunk (stop if none), no uncommitted changes (stop if dirty).

Base branch: use release/* if the branch was created from one, otherwise trunk.

From the dynamic context above (read full diffs only if the stat summary is ambiguous), determine:

• Change type: Fix, Add, Update, Dev, Tweak, Performance, or Enhancement
• Significance: Patch (most common), Minor (new features), Major (breaking — rare)
• Bug fix? Look for issue refs in commits/branch name (e.g., #12345, fix/issue-12345)
• UI changes? Changes in client/, templates/, CSS/SCSS, JSX/TSX
• Plugin-affecting? Code shipped to users = yes. CI/CD, workflows, tooling, docs = no. This drives the Milestone and Changelog decisions in Step 3.

2. Gather Context

Extract issue/PR refs from commits and branch name:

• Issue ref: use what's in commits/branch if present; otherwise omit Closes # (Linear refs are internal — only reference GitHub issues in PRs).
• Bug-fix origin PR: if a bug fix and no PR ref is in the diff/commits, search history (git log -S on touched lines) to find the introducing PR; omit Bug introduced in PR #XXXX. if not found.
• Motivation: infer from diff and commit messages. Use the strongest summary you can; don't block on missing context.

3. Generate PR Title + Body

Title (under 70 chars, verb-first — the repo convention):

• Fix <what was broken>, Add <what>, or other verb (Restore, Bump, Prepare, etc.)
• Optional area prefix: [Email Editor] Fix double margin-top in flex layout
• No fix:/feat: prefixes. No Linear ticket refs — Linear is internal, PRs are public.

Body — fill in .github/PULL_REQUEST_TEMPLATE.md (loaded in dynamic context above) section by section, in order. The template's HTML comments describe what each section is for — follow them as the per-section instructions. Repo-specific rules that the template doesn't carry, layered on top:

• Changes proposed: 2-3 sentences. Lead with WHY, then WHAT. No filler ("This PR addresses..."). Drop the Closes # . line if you don't have a GitHub issue ref. Drop the Bug introduced in PR # . line if not a bug fix or origin PR unknown.
• Milestone: tick the auto-assign box only for plugin-affecting changes. The section itself stays — the template marks it do-not-remove.
• Changelog entry:
  • Plugin-affecting, no changelog files in the diff → tick Automatically create with Significance, Type, and a user-facing Message.
  • Plugin-affecting with changelog files already in the diff → tick does not require with the Comment "Created manually."
  • Not plugin-affecting → tick does not require with a Comment explaining why (e.g., "Internal tooling, not shipped to merchants").

After filling, keep the template's HTML comments (<!-- -->) — they support PR automation and GitHub tests. Remove only unfilled placeholder lines that are actual visible placeholders (e.g., Closes # ., Bug introduced in PR # .).

4. Preview

State the generated title and body before executing.

5. Push and Create

git push -u origin $(git branch --show-current)
gh pr create --draft --title "<title>" --base <base-branch> --body "$(cat <<'PRBODY'
<full PR body>
PRBODY
)"

Output the PR URL. If UI changes need screenshots, remind the user.

Constraints

• No Co-Authored-By lines or self-attribution
• Never commit code — pushing is fine
• Preserve the PR template section headings and HTML comments exactly; the Milestone section is required in every PR body, ticked or not — its <!-- milestone-target-selection --> markers drive PR automation
• Changelog checkboxes must match CI automation format
