Claude Command: Commit (Git-only)
This command works without any package manager/build tools, using only Git to:
- Read changes (staged/unstaged)
- Determine if changes should be split into multiple commits
- Generate Conventional Commits style messages with optional emoji for each commit
- Execute
git add and git commit as needed (runs local Git hooks by default; use --no-verify to skip)
Usage
/git-commit
/git-commit --no-verify
/git-commit --emoji
/git-commit --all --signoff
/git-commit --amend
/git-commit --scope ui --type feat --emoji
Options
--no-verify: Skip local Git hooks (pre-commit/commit-msg etc.).--all: When staging area is empty, automatically git add -A to include all changes in the commit.--amend: Amend the last commit without creating a new one (preserves author and timestamp unless local Git config specifies otherwise).--signoff: Add Signed-off-by line (use when following DCO process).--emoji: Include emoji prefix in commit message (omit for plain text).--scope <scope>: Specify commit scope (e.g., ui, docs, api), written to message header.--type <type>: Force commit type (e.g., feat, fix, docs), overrides automatic detection.
Note: If the framework doesn't support interactive confirmation, enable confirm: true in front-matter to avoid mistakes.
What This Command Does
-
Repository/Branch Validation
- Check if in a Git repository using
git rev-parse --is-inside-work-tree.
- Read current branch/HEAD status; if in rebase/merge conflict state, prompt to resolve conflicts first.
-
Change Detection
- Get staged and unstaged changes using
git status --porcelain and git diff.
- If staged files = 0:
- If
--all is passed → Execute git add -A.
- Otherwise prompt choice: continue analyzing unstaged changes for suggestions, or cancel to manually group staging.
-
Split Suggestions (Split Heuristics)
- Cluster by concerns, file modes, change types (e.g., source code vs docs/tests; different directories/packages; additions vs deletions).
- If multiple independent changesets or large diff detected (e.g., > 300 lines / across multiple top-level directories), suggest splitting commits with pathspecs for each group (for subsequent
git add <paths>).
-
Commit Message Generation (Conventional with Optional Emoji)
- Auto-infer
type (feat/fix/docs/refactor/test/chore/perf/style/ci/revert...) and optional scope.
- Generate message header:
[<emoji>] <type>(<scope>)?: <subject> (first line ≤ 72 chars, imperative mood, emoji included only with --emoji flag).
- Generate message body:
- Must have a blank line after the subject.
- Use list format, each item starts with
-.
- Each item must use imperative verb-first sentences (e.g., "add…", "fix…", "update…").
- Colon-separated formats are prohibited (e.g.,
"Feature: description", "Impl: content").
- Describe the motivation, implementation details, or impact scope (3 items or fewer recommended).
Best Practices for Commits
- Atomic commits: One commit does one thing, easier to trace and review.
- Group before committing: Split by directory/module/feature.
- Clear subject: First line ≤ 72 chars, imperative mood.
- Body with context: Explain motivation, solution, and impact scope (colon-separated formats prohibited).
- Follow Conventional Commits:
<type>(<scope>): <subject>.
Type to Emoji Mapping (When --emoji is Used)
- ✨
feat: New feature
- 🐛
fix: Bug fix (includes 🔥 remove code/files, 🚑️ hotfix, 👽️ adapt to external API changes, 🔒️ security fix, 🚨 fix warnings, 💚 fix CI)
- 📝
docs: Documentation and comments
- 🎨
style: Code style/formatting (no semantic changes)
- ♻️
refactor: Refactoring (no new features, no bug fixes)
- ⚡️
perf: Performance improvements
- ✅
test: Add/fix tests, snapshots
- 🔧
chore: Build/tools/misc tasks (merge branches, update configs, release tags, pin dependencies, .gitignore, etc.)
- 👷
ci: CI/CD configuration and scripts
- ⏪️
revert: Revert commits
- 💥
feat: Breaking changes (explained in BREAKING CHANGE: section)
If --type/--scope is passed, it will override auto-detection.
Emoji is only included when --emoji flag is specified.
Guidelines for Splitting Commits
- Different concerns: Unrelated feature/module changes should be split.
- Different types: Don't mix
feat, fix, refactor in the same commit.
- File modes: Source code vs docs/tests/configs should be grouped separately.
- Size threshold: Large diffs (e.g., >300 lines or across multiple top-level directories) should be split.
- Revertability: Ensure each commit can be independently reverted.
Examples
Good (with --emoji)
- ✨ feat(ui): add user authentication flow
- 🐛 fix(api): handle token refresh race condition
- 📝 docs: update API usage examples
- ♻️ refactor(core): extract retry logic into helper
- ✅ test: add unit tests for rate limiter
- 🔧 chore: update git hooks and repository settings
- ⏪️ revert: revert "feat(core): introduce streaming API"
Good (without --emoji)
- feat(ui): add user authentication flow
- fix(api): handle token refresh race condition
- docs: update API usage examples
- refactor(core): extract retry logic into helper
- test: add unit tests for rate limiter
- chore: update git hooks and repository settings
- revert: revert "feat(core): introduce streaming API"
Good (with Body)
feat(auth): add OAuth2 login flow
- implement Google and GitHub third-party login
- add user authorization callback handling
- improve login state persistence logic
Closes #42
fix(ui): fix button spacing on mobile devices
- adjust button padding to fit small screens
- fix styling issues on iOS Safari
- optimize touch target size
Good (with BREAKING CHANGE)
feat(api)!: redesign authentication API
- migrate from session-based to JWT authentication
- update all endpoint signatures
- remove deprecated login methods
BREAKING CHANGE: authentication API has been completely redesigned, all clients must update their integration
Split Example
- `feat(types): add new type defs for payment method`
- `docs: update API docs for new types`
- `test: add unit tests for payment types`
- `fix: address linter warnings in new files` ← (if your repo has hook errors)
Important Notes
- Git only: No package manager/build commands (
pnpm/npm/yarn etc.).
- Respects hooks: Executes local Git hooks by default; use
--no-verify to skip.
- No source code changes: Command only reads/writes
.git/COMMIT_EDITMSG and staging area; doesn't directly edit working directory files.
- Safety prompts: In rebase/merge conflicts, detached HEAD states, prompts to handle/confirm before continuing.
- Auditable and controllable: If
confirm: true is enabled, each actual git add/git commit step requires confirmation.
