# Create Branch Make + checkout new branch. No confirm. ## Flow 1. Parallel: `git status` + `git branch --show-current`. 2. Dirty tree -> stop. Tell user to stash or commit first. Why -> `checkout -b` carries staged + unstaged changes into the new branch silently, mixing them with future work. 3. Pick base: - Default `main`. Fall back `master`. - On feature branch + user wants to branch off it -> use current. Skip step 4's fetch; go to step 5 "off current" variant. 4. Exists? `git show-ref --verify --quiet refs/heads/<name>` -> 0 = stop, surface conflict, no overwrite. Why -> `checkout -b` errors anyway, but check early so message is clean + no half-state. 5. Create: - Off `<base>` (default): `git fetch origin <base>` + `git checkout -b <name> origin/<base>`. - Off current: `git checkout -b <name>` (no fetch, no remote ref — current HEAD is the base). 6. Print branch + base. ## Naming `<type>/<short-kebab-desc>` or `<type>/<scope>-<short-kebab-desc>`. ### Type Same set + picks as `git-commit`. See that skill's **Type pick** + **Tiebreakers** for disambiguation. Quick list: `feat|fix|perf|refactor|docs|test|build|ci|chore`. ### Desc - kebab-case. Not camel / snake. - Imperative present: `add`, `fix`, `remove`. Not `added`, `fixes`. - < ~50 chars. - No ticket IDs unless asked. Why -> history readable + tool-agnostic; trackers come+go, branches stay. Asked -> suffix: `feat/add-auth-middleware-PROJ-123`. ### Examples - `feat/add-oauth-login` - `fix/api-time
