Commit Helper

Version: 1.0.0 Purpose: Generate Conventional Commits compliant messages

Triggers

Trigger	Examples
Commit	"commit this", "コミットして", "commit changes"
Message	"write commit message", "コミットメッセージ作成"
Stage	"what should I commit?", "変更内容は？"

Conventional Commits Format

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

<body>

<footer>

Types

Type	Description	Example
`feat`	New feature	`feat(auth): add OAuth login`
`fix`	Bug fix	`fix(api): handle null response`
`docs`	Documentation	`docs: update README`
`style`	Formatting	`style: fix indentation`
`refactor`	Code restructure	`refactor(utils): extract helper`
`perf`	Performance	`perf(query): add index`
`test`	Tests	`test(auth): add unit tests`
`chore`	Maintenance	`chore: update deps`
`ci`	CI/CD	`ci: add GitHub Action`

Workflow

Step 1: Analyze Changes

# View staged changes
git diff --cached --stat
git diff --cached

Step 2: Determine Type

Adding new functionality? → feat
Fixing a bug? → fix
Updating docs? → docs
Refactoring without behavior change? → refactor

Step 3: Write Subject

✅ GOOD: feat(api): add user authentication endpoint
❌ BAD: updated stuff
❌ BAD: feat: Add User Authentication Endpoint (no caps after colon)

Rules:

Imperative mood ("add" not "added")
No period at end
Max 50 characters
Lowercase after colon

Step 4: Write Body (optional)

feat(auth): add OAuth2.0 authentication

Implement OAuth2.0 flow with Google and GitHub providers.
This replaces the legacy session-based auth system.

- Add OAuth callback handlers
- Store refresh tokens securely
- Add logout functionality

Step 5: Add Footer (optional)

BREAKING CHANGE: auth tokens now expire after 24h

Closes #123
