PR & Branch Naming

You generate a conventionally-named branch and a matching PR title from a feature description, then optionally check out the branch and/or open a PR — but only with explicit user confirmation.

Step 1: Get the feature description

The user's input is in $ARGUMENTS. It can be:

1. A description — use it directly
2. Empty — try to infer the work from git status and the most recent commits (git log -n 5 --oneline). If you can infer it, propose it back to the user for confirmation. If not, ask: "What's the feature or change this branch is for?"

Don't fabricate a description. If there's nothing to go on, ask.

Step 2: Pick the type and scope

Type (one of)

Pick the type that best matches the description. For designer-authored work, the common types are feat and experimental.

Scope

The area of the product affected — short, lowercase, single word if possible. Examples: playground, dashboard, auth, onboarding, billing.

Infer the scope from the description. If it's genuinely ambiguous, ask once: "What part of the product does this touch — dashboard, auth, etc.?" Don't pepper the user with questions.

Step 3: Pick the branch prefix

The prefix should align with the type. Use feature/ for feat, bugfix/ for fix, and so on.

Step 4: Generate the names

Branch name

Format: <prefix>/<kebab-description>

Rules:

• Lowercase only
• Hyphen-separated (no underscores, no spaces)
• No trailing hyphen
• Keep it concise — aim for 3–6 words in the description portion
• Drop filler words (the, a, for, to, make)

Example: feature/patient-based-messaging

PR title

Format: <type>(<scope>): <short description>

Rules:

• Description in plain language, sentence case, no trailing period
• Concise — fits on one line
• Mirrors what the branch is about, but reads naturally to a human reviewer

Example: feat(playground): v1 prototype — patient-based messaging flow

Step 5: Show the result

Present both names plus a one-line rationale, in this format:

Branch:    feature/patient-based-messaging
PR title:  feat(playground): v1 prototype — patient-based messaging flow
 
Type: feat (new UI work) · Scope: playground · Prefix: feature/

Step 6: Offer to apply

Ask the user whether to:

1. Check out the branch — run git checkout -b <branch>
2. Open a draft PR — run gh pr create --draft --title "<title>" --body "<one-line description>"
3. Do both
4. Neither — they'll copy the names themselves

Before running either command, check the preconditions and stop with a clear message if they fail:

• For `git checkout -b`: run git status first. If the working tree is dirty, surface that and ask whether to proceed anyway, stash, or abort. If a branch with the same name already exists, suggest a numeric suffix (-2).
• For `gh pr create`: run gh auth status first. If unauthenticated, tell the user to run gh auth login and stop. Don't open the PR from a branch with no commits ahead of base — check with git log <base>..HEAD --oneline and warn if empty.

Never run destructive git operations (reset --hard, branch -D, push --force) as part of this skill.

Notes

• If the user is already on a non-default branch when invoking this skill, ask whether the new branch should be cut from main/master or from the current branch.
• If multiple changes are described (e.g., "fix the login bug and add a new dashboard widget"), suggest splitting into two branches/PRs rather than smushing them into one.
• The PR title's description can use an em dash (—) to add a qualifier, as in the example. Don't overuse it.
