Commit

Create a git commit for the staged changes.

Pre-commit step: branch selection

Before committing, check the current branch:

1. git branch --show-current
2. Determine the repository's default branch (main or master — e.g. via git symbolic-ref --short refs/remotes/origin/HEAD, falling back to whichever of main/master exists locally).
3. If the current branch is the default branch: create and switch to a new branch via git checkout -b feature/<short-kebab-description>, where <short-kebab-description> is a meaningful slug derived from the change being committed (e.g. feature/province-division-config). Do this before staging/committing anything else.
4. If it is anything other than the default branch (i.e. already on a feature branch or other non-default branch): leave the branch as-is — do not create or switch branches.

Rules

• Subject line: short, imperative, no period
• Explain why, not what — the diff already shows what changed
• No bullet-point summaries of changed files
• Always add a Co-Authored-By trailer for the model in use, e.g. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
• If a project-specific pre-commit step bumps a version number, only ever increment the minor/patch segment. The major (or milestone) segment is a human decision — never bump it automatically, and never let an overflowing minor segment roll over into it. If a project's version-bump instructions are ambiguous about this, stop and ask a human rather than guessing.
