git-commits - SKILL.md Agent Skill

name: git-commits description: Use when preparing, splitting, reviewing, or creating git commits in this repo, especially after larger implementations that should be broken into independently verified commits.

Git Commits

Message Style

Use the following commit message template:

<type>(<scope>): <subject>

<description>

The can be: agents, chore, ci, docs, feat, fix, perf, refactor, test, tool.
The can be a project, package, or app name; omit the scope and its wrapped parens if none is clear.
The and should explain the motivations and changes.
Include a description body for every commit unless the staged change is truly mechanical or trivial and the subject fully explains it.
Keep every commit message line 72 characters or fewer. Hard-wrap body text to 72 columns before committing; do not leave long single-line descriptions.
Use imperative mood; be concise
Include user-provided context when it improves the message
Do not include AI attribution in or after the description

Commit Boundaries

Each commit should be independently understandable and shippable.

Split unrelated behavior, package areas, generated artifacts, and dependency bumps into separate commits.
For larger implementations, commit in vertical slices: tests or fixtures, implementation, docs/examples, and follow-up polish can be separate only when each commit still makes sense on its own.
Do not mix mechanical formatting with behavioral changes unless the formatter only touched the files required for that change.
Do not include local artifacts from .agents/ignore/, .context/, logs, build outputs, or editor files.
Before committing, inspect staged changes with git diff --cached and make sure every staged file belongs to the commit's stated purpose.

If two changes would need different test commands or different reviewers, they usually deserve different commits.

Verification Before Each Commit

Every commit should be verified before it is created.

If the full baseline fails for unrelated pre-existing issues, say that in the commit handoff and include the first relevant failure. Do not describe the commit as fully verified unless the required commands actually passed.

Creating Commits

Use non-interactive commands where possible:

git status --short
git diff -- <paths>
git add <paths>
git diff --cached
git commit -m "<message>"

Include a wrapped commit body for ordinary source changes:

git commit -F - <<'COMMIT'
fix(diffs): Keep scroll focus stable

Keep focus anchored when rows are recycled during scroll so keyboard
navigation does not lose the active item.
COMMIT

Use a subject-only commit only for changes where no useful description exists, such as a typo fix or a purely mechanical formatting commit.
