Commit

Commit Skill

Generate standardized git commit messages following the project's Conventional Commits specification.

Commit Message Format

(): 

Type (Required)

Based on project history analysis, use the following types:

| Type | Description | Example | |------|-------------|---------| | feat | New feature | feat: add user authentication | | fix | Bug fix | fix: resolve login timeout issue | | docs | Documentation only | docs: update API documentation | | style | Code style (formatting, semicolons, etc.) | style: fix indentation | | refactor | Code refactoring (no feature change) | refactor: extract validation logic | | perf | Performance improvement | perf: optimize database queries | | test | Add or modify tests | test: add unit tests for auth module | | chore | Build process or auxiliary tools | chore: update dependencies | | ci | CI/CD configuration | ci: add GitHub Actions workflow | | build | Build system changes | build: upgrade webpack to v5 |

Scope (Optional)

Scope indicates the affected module or area, enclosed in parentheses:

feat(devflow): add diff-review-doc skill
fix(auth): resolve token refresh issue

Common scopes in this project:

• Plugin names: devflow, blocklet, arcblock-context
• Skill names: blocklet-dev-setup, blocklet-pr
• Module names: specific functional modules

Subject (Required)

• Use imperative mood: "add" not "added" or "adds"
• Lowercase first letter
• No period at the end
• Keep under 50 characters
• Describe what the commit does

Good examples:

• feat: add blocklet-branch skill for branch management
• fix: resolve gh command order issue
• docs: update installation guide

Bad examples:

• feat: Added new feature. (wrong tense, has period)
• Fix bug (missing type prefix)
• feat: This commit adds a new feature that... (too verbose)

Body (Optional)

• Wrap at 72 characters
• Explain "what" and "why" vs "how"
• Separate from subject with blank line

Footer (Optional)

• Reference issues: Closes #123
• Breaking changes: BREAKING CHANGE: description

Workflow

When user requests to create a commit:

Step 1: Check Current Status

git status
git diff --staged
git diff

Step 2: Verify All Changes Are Staged

IMPORTANT: If there are unstaged changes, use AskUserQuestion to confirm how to proceed.

Check for unstaged changes:

• Modified files not staged (Changes not staged for commit)
• Untracked files (Untracked files)

If unstaged changes exist:

1. List all unstaged/untracked files
2. Use AskUserQuestion tool to ask user how to proceed:

{
  "questions": [{
    "question": "There are unstaged changes. How would you like to proceed?",
    "header": "Unstaged",
    "options": [
      {"label": "Stage all", "description": "Run `git add .` to stage all changes"},
      {"label": "Abort", "description": "Cancel the commit and handle changes manually"}
    ],
    "multiSelect": false
  }]
}

1. If user selects "Stage all": run git add . then continue to Step 3
2. If user selects "Abort": stop the workflow and inform user to stage changes manually
3. DO NOT proceed until all intended changes are staged

Step 3: Analyze Staged Changes

Only proceed if all changes are properly staged:

• Identify the type of change (feature, fix, docs, etc.)
• Determine the scope if applicable
• Summarize the change concisely

Step 4: Generate and Confirm Commit Message

Generate the commit message following the format, then use AskUserQuestion tool to confirm:

Proposed commit message:

(): 

Co-Authored-By: Claude 

Use AskUserQuestion tool with options:

• Approve - Proceed to commit
• Edit message - User wants to modify the message
• Cancel - Abort the commit

Example AskUserQuestion usage:

{
  "questions": [{
    "question": "Proceed with this commit message?",
    "header": "Commit",
    "options": [
      {"label": "Approve", "description": "Create the commit with this message"},
      {"label": "Edit message", "description": "Modify the commit message"},
      {"label": "Cancel", "description": "Abort the commit"}
    ],
    "multiSelect": false
  }]
}

Step 5: Execute Commit (Only After User Confirmation)

git commit -m "$(cat (): 

Co-Authored-By: Claude 
EOF
)"

Step 6: Verify Commit

git log -1 --oneline

Examples from Project History

feat: parse blocklet urls from dev output instead of constructing from did
feat: add blocklet-branch skill for branch management
feat: enhance blocklet-server-dev-setup skill with GitHub CLI authentication guidance
feat(devflow): add diff-review-doc skill (#1)
fix: gh move top
docs: prefer git URL format for marketplace installation
chore: initial commit
chore: cleanup hello world plugin

Rules

1. Always use English for commit messages
2. Always use lowercase type prefix
3. Always use imperative mood in subject
4. Never end subject with period
5. Add Co-Authored-By footer when AI generates the commit
6. Keep subject under 50 characters when possible
7. Reference PR/Issue numbers when applicable: (#123)
