Conventional Commits

Purpose

Use this Skill whenever you need to write, modify, optimize, or review a Git Commit Message.

Applicable scenarios include, but are not limited to:

Writing a new Git Commit Message
Generating a Commit Message based on code changes
Modifying an existing Commit Message
Standardizing commit conventions across a team
Working with automation tools such as commitlint, semantic-release, release-please, and Changesets
Automatically generating a Changelog or version number based on commits

Not applicable to:

Pull Request titles (unless your team requires the same convention)
Issue titles
The body of Release Notes
General text descriptions

This Skill follows the Conventional Commits 1.0.0 specification. (Conventional Commits)

ALWAYS (Mandatory Rules)

MUST use the following basic format:

<type>[optional scope][!]: <description>

MUST use a standard ASCII colon (:) followed by a single space.
MUST choose a clear type for every commit.
MUST use feat when introducing a new feature.
MUST use fix when fixing a bug.
MUST mark breaking changes using either ! or BREAKING CHANGE:.
MUST keep the title (description) concise and focused on the primary change in the commit.
MUST wrap scope (if present) in parentheses.
MUST leave one blank line between the title and the body (if present).
MUST leave one blank line between the body and the footer (if present).
MUST keep BREAKING CHANGE: fully uppercase.
MUST ensure each Commit represents a single primary purpose. If multiple unrelated changes are included, split them into separate Commits. (Conventional Commits)

NEVER (Prohibited Practices)

Do not omit the type

Reason: Automation tools cannot recognize the commit type.

❌

Fix login issue

✅

fix(auth): Fix login failure

Do not use meaningless descriptions

Reason: They do not help readers understand the commit history.

❌

feat: update

fix: change

chore: modify

✅

feat(auth): Add support for WeChat login

fix(cache): Fix duplicate requests caused by cache invalidation

Do not combine multiple unrelated changes into a single Commit

Reason: It reduces readability and negatively impacts version analysis and rollback.

❌

feat: Add user management, fix payment bug, and update README

✅

feat(user): Add user management system

fix(payment): Fix payment failure

docs: Update README

Do not misuse `feat` and `fix`

Reason: It affects automatic Semantic Version calculation.

❌

feat: Fix login issue

✅

fix(auth): Fix login issue

Do not omit `BREAKING CHANGE`

Reason: Major compatibility changes cannot be detected automatically.

❌

feat(api): Remove v1 API

✅

feat(api)!: Remove v1 API

feat(api): Remove v1 API

BREAKING CHANGE: Remove all v1 endpoints. Please migrate to v2.

Common Patterns

Pattern 1: Adding a New Feature

feat(auth): Add GitHub OAuth login support

Pattern 2: Fixing a Bug

fix(parser): Fix JSON parsing error

Pattern 3: Using a Scope

feat(cli): Add init command

refactor(core): Refactor plugin loading workflow

Pattern 4: Including a Body

feat(storage): Add object storage support

Add support for both S3 and MinIO backends.

Unify the Storage Provider interface for easier future extensions.

Pattern 5: Including a Footer

fix(api): Fix incorrect pagination parameters

Pagination parameters were incorrectly ignored when offset was 0.

Pattern 6: Breaking Changes

feat(config)!: Refactor configuration system

feat(config): Refactor configuration system

BREAKING CHANGE: Change the configuration file format from YAML to TOML.

Pattern 7: Recommended Types

feat(ui): Add theme switching

fix(login): Fix login issue

docs: Update API documentation

style: Adjust code formatting

refactor(core): Refactor task scheduler

perf(cache): Improve cache hit rate

test(api): Add API tests

build: Upgrade webpack

ci: Update GitHub Actions

chore: Update development tool configuration

revert: Revert previous changes

Where:

Type	Purpose
feat	New feature
fix	Bug fix
docs	Documentation changes
style	Code style changes that do not affect logic
refactor	Code refactoring without adding features or fixing bugs
perf	Performance improvements
test	Test-related changes
build	Build system or dependency changes
ci	CI/CD changes
chore	Miscellaneous maintenance
revert	Revert a previous commit

Notes

scope is optional and should use a module name that accurately describes the affected area, such as api, cli, core, ui, auth, or parser.
In addition to feat and fix, new type values may be introduced according to team conventions, but they should remain consistent across the project. (Conventional Commits)
feat typically corresponds to a MINOR update under Semantic Versioning (SemVer).
fix typically corresponds to a PATCH update under Semantic Versioning (SemVer).
Any commit type containing BREAKING CHANGE or ! corresponds to a MAJOR update. (Conventional Commits)
Footers are recommended to follow the Git Trailer format, for example:

Refs: #123
Closes: #456

It is recommended to keep Commit titles short, focused, and readable. Each Commit should represent a single logical change to facilitate review, rollback, and automatic Changelog generation.
