Create conventional commit messages following best conventions. Use when committing code changes, writing commit messages, or formatting git history. Follows conventional commits specification.

AI-generated overview

Guides writing conventional commit messages and branch names for git changes.

What it does
Provides conventions for creating git commit messages in the Conventional Commits format, including header, body and footer structure. It lists commit types such as feat, fix, docs and refactor, subject line rules, body guidelines, breaking change and revert formats, and branch naming patterns. It produces formatted commit messages and branch names rather than code.
When to use it
Use when committing code changes, drafting commit messages, or formatting git history. Also relevant when checking whether work is on a feature branch before committing.
Requirements
Requires git for the branch-checking commands shown. No scripts or packages are shipped; the skill is instructions only.

Conventional Commit Messages

Follow these conventions when creating commits.

Prerequisites

Before committing, ensure you're working on a feature branch, not the main branch.

bash
# Check current branchgit branch --show-current

If you're on main or master, create a new branch first:

bash
# Create and switch to a new branchgit checkout -b <type>/<short-description>

Branch naming should follow the pattern: <type>/<short-description> where type matches the commit type (e.g., feat/add-user-auth, fix/null-pointer-error, refactor/extract-validation).

Format

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

The header is required. Scope is optional. All lines must stay under 100 characters.

Commit Types

TypePurpose
buildBuild system or CI changes
choreRoutine maintenance tasks
ciContinuous integration configuration
depsDependency updates
docsDocumentation changes
featNew feature
fixBug fix
perfPerformance improvement
refactorCode refactoring (no behavior change)
revertRevert a previous commit
styleCode style and formatting
testTests added, updated or improved

Subject Line Rules

  • Use imperative, present tense: "add feature" not "added feature"
  • Do not capitalize the first letter
  • No period at the end
  • Maximum 70 characters

Body Guidelines

  • Explain what and why, not how
  • Use imperative mood and present tense
  • Include motivation for the change
  • Contrast with previous behavior when relevant

Conventional Commits

The commit contains the following structural elements, to communicate intent to the consumers of your library:

  • fix: a commit of the type fix patches a bug in your codebase (this correlates with PATCH in Semantic Versioning).
  • feat: a commit of the type feat introduces a new feature to the codebase (this correlates with MINOR in Semantic Versioning).
  • BREAKING CHANGE: a commit that has a footer BREAKING CHANGE:, or appends a ! after the type/scope, introduces a breaking API change (correlating with MAJOR in Semantic Versioning). A BREAKING CHANGE can be part of commits of any type.
  • types other than fix: and feat: are allowed, for example @commitlint/config-conventional (based on the Angular convention) recommends build:, chore:, ci:, docs:, style:, refactor:, perf:, test:, and others.
  • footers other than BREAKING CHANGE: <description> may be provided and follow a convention similar to git trailer format.

Examples

Simple fix

fix(api): handle null response in user endpoint
The user API could return null for deleted accounts, causing a crashin the dashboard. Add null check before accessing user properties.

Feature with scope

feat(alerts): add Slack thread replies for alert updates
When an alert is updated or resolved, post a reply to the originalSlack thread instead of creating a new message. This keeps relatednotifications grouped together.

Refactor

refactor: extract common validation logic to shared module
Move duplicate validation code from three endpoints into a sharedvalidator class. No behavior change.

Breaking change

feat(api)!: remove deprecated v1 endpoints
Remove all v1 API endpoints that were deprecated in version 23.1.Clients should migrate to v2 endpoints.
BREAKING CHANGE: v1 endpoints no longer available

Revert Format

revert: feat(api): add new endpoint
This reverts commit abc123def456.
Reason: Caused performance regression in production.

Principles

  • Each commit should be a single, stable change
  • Commits should be independently reviewable
  • The repository should be in a working state after each commit
