Open Pull Request

Open a Pull Request

When to Use

Use this skill only when the user explicitly requests to open a pull request (e.g. "open a pull request", "open an pull request", "create a pull request"). Do not run git commit, push, or gh pr create for any other request.

Preconditions

1. Working tree: Confirm that current changes (staged or unstaged) are what the user wants to commit. If the state is unclear or already on a feature branch with unpushed commits, ask before proceeding.
2. GitHub CLI: Require gh installed and authenticated. Run gh auth status; if not OK, instruct the user to install GitHub CLI and run gh auth login, then stop.

Workflow

1. Create a new branch

• Create a new branch from current HEAD: git checkout -b <branch-name>.
• Branch name: Use user-provided name if given. Otherwise derive from the commit message: e.g. feat/scope-short-desc, fix/short-desc, enhance/improve-x, ci/update-workflow, or (deps)/go-mod (slug from the first line of the conventional commit). These patterns align with .github/labeler.yml so the labeler auto-applies PR labels (feature, bug, enhancement, github-actions, dependencies). For breaking changes, include ! in the branch name to get the breaking-change label. Prefer lowercase, hyphens; avoid spaces.

2. Stage and commit

• Run git add .
• Commit message: Use conventional style per project (e.g. feat(scope): description, fix(scope): description). If the user provided a message, use it; otherwise generate from git status and git diff (or git diff --staged after add).
• Run git commit -s -m "<message>" so the commit includes a Signed-off-by line (DCO). Do not add a Made-with: Cursor or similar trailer to the commit message. The repo has the DCO bot enabled; PRs must have all commits signed off.

3. Push and create PR

• Push: git push -u origin <branch-name>
• Create PR: gh pr create using the repository's pull request template. Populate all sections (see PR body below). The neptune label is applied automatically; do not add it manually.

4. Safety

• Do not run git push, git commit, or gh pr create unless the user has explicitly requested to open a pull request.
• If the repo is in an unexpected state (e.g. already on a feature branch with unpushed commits, or detached HEAD), ask the user before creating a new branch or pushing.

PR body (repo template)

The repo uses .github/pull_request_template.md. When creating the PR (e.g. gh pr create --body-file - or by filling the template), populate:

• What is this feature? – Short description; correlates with issues.
• Why do we need this feature? – Problem or context (from commit/conversation).
• Who is this feature for? – Target user or use case.
• Related issues – e.g. Fixes #123 or Relates to #456 if applicable.
• Notes for reviewers – Optional; call out design decisions or areas to focus on.
• Checklist – Mark as appropriate: breaking changes (Yes/No/N/A), docs updated, tests added/updated.
• AI Summary – For AI reviewers; fill from changed files and context:
  • Scope: e.g. lambda (config, webhooks, main), docs, AGENTS.md
  • Type: feat | fix | docs | refactor
  • Key files/areas: paths from git diff --name-only or conversation (e.g. lambda/pkg/config/config.go, docs/github-app-and-lambda.md)

Generate the body from the commit message and git diff --name-only (or equivalent) so the template sections are filled accurately.
