Git Create Pr

Create Pull Request

Create a GitHub Pull Request following conventional commits, pre-filled with the repo's PR template, and opened in the browser for final review.

Every PR bullet must map to an actual commit or diff hunk: drop claims you can't back with evidence in git log or git diff.

Invariant: never mutate the user's files to satisfy a precondition. If a check in step 1 fails, report it and stop. Do not run git checkout, git restore, git reset, git stash, or git clean against the user's tracked files to "fix" a dirty tree, and do not switch branches to route around a main/master check, those are the user's decisions, not this skill's. The only git commands this skill runs against the working tree are read-only until step 7's git push.

Workflow

1. Validate preconditions (run this before anything else, including branch analysis)

   • Check working tree is clean: git status --porcelain. Any output means it's dirty.
     • If dirty: stop immediately. Show the git status --porcelain output and tell the user to commit or stash their changes first, e.g. Working tree has uncommitted changes: M README.md. Commit or stash before opening a PR. Do not proceed to step 2, and do not touch the listed files.
   • Get current branch: git branch --show-current.
     • If it's main or master: stop immediately. Tell the user there's no feature branch to open a PR from, e.g. Currently on main — check out a feature branch first. Do not proceed.
   • Check commits exist: git log origin/<base>..HEAD --oneline. If empty, stop and say there's nothing to open a PR for.
   • Extract ticket ID from branch name (e.g., ABC-123 from feature/ABC-123_description)

2. Determine base branch

   • Use --base/-b argument if provided
   • Otherwise: gh repo view --json defaultBranchRef -q .defaultBranchRef.name
   • Fall back to main if detection fails

3. Analyze changes

   • git log origin/<base>..HEAD --format="%h %s" for commits
   • git diff origin/<base>...HEAD --stat for file changes
   • Synthesize these directly in the main thread: a subagent fan-out is overkill for what one git log + one diff --stat already summarizes. Only reach for a subagent if the diff is too large to fit in context.

4. Generate PR title (conventional commit format, max 72 chars)

   • type(scope): [TICKET-123] description or type(scope): description if no ticket
   • Types: feat, fix, docs, style, refactor, perf, test, build, ci, chore
   • Examples: feat(auth): [ABC-123] add OAuth2 login support, fix(api): resolve null pointer in user endpoint

5. Fill PR template

   • Look for .github/pull_request_template.md and fill it without changing its structure
   • If none exists, use:

     ## Summary
     [Brief description]
     
     ## Changes
     - [Bullet points from commits]
     
     ## Testing
     - [ ] Tests added/updated
     - [ ] Manual testing completed
     

   • Save to BODY_FILE="/tmp/pr-body-$(date +%s).md"

6. Ask for confirmation

   • Show a compact summary: ticket, commit count, authors (keep lines under 60 chars)
   • Preview the generated title and body
   • If the repo has CI configured (.github/workflows/*.yml) and tests haven't been verified locally this session, suggest running the cc-arsenal:ci-local skill first (via the Skill tool where available, otherwise run the workflow's gating steps locally by hand): cheaper to catch a failure now than after the PR is open
   • Ask: Create PR? (y/n/e to edit): (accept y/yes/n/no/e/edit)
   • On e, ask for custom title/body

7. Push and create PR (after confirmation)

   # Push first — required before gh pr create can reference the branch
   git push -u origin $(git branch --show-current)
   
   # BODY_FILE is the file written in step 5
   gh pr create \
     --title "type(scope): [TICKET] description" \
     --body-file "$BODY_FILE" \
     --base <determined-base-branch> \
     --web
   

   • Do not combine --reviewer, --assignee, or --label with --web: they conflict. The user adds those in the web UI.

Argument Parsing

• --base branch / -b branch: target branch, defaults to repo default
• --draft / -d: adds --draft to gh pr create

Examples

git-create-pr                    # uses repo default base branch
git-create-pr --base develop     # target a specific base branch
git-create-pr --draft            # create as draft PR
git-create-pr -b develop -d      # both

After pushing, the PR opens in the browser pre-filled with title and body. Add reviewers/labels there.

Precondition failure (dirty tree, stop before any analysis):

Working tree has uncommitted changes:
 M README.md
Commit or stash before opening a PR. Not proceeding.

No git checkout, git push, or gh pr create runs after this: the turn ends here.
