Pull Request Skill

Generate standardized Pull Requests by analyzing the diff between current branch and main branch.

Step 0: Check for Project PR Template (IMPORTANT)

CRITICAL: Before generating PR content, ALWAYS check if the project has a custom PR template:

# Check for PR template in common locations
ls -la .github/PULL_REQUEST_TEMPLATE.md 2>/dev/null || \
ls -la .github/PULL_REQUEST_TEMPLATE/ 2>/dev/null || \
ls -la docs/PULL_REQUEST_TEMPLATE.md 2>/dev/null

If a PR template exists:

  1. Read the template file using the Read tool
  2. Use that template's structure for the PR body
  3. Fill in each section according to the template's format and comments
  4. Keep any checkboxes or structured lists from the template

If no PR template exists: Use the default template defined below.

PR Template (Default - Use only if no project template exists)

Based on analysis of high-quality PRs, use this template:

Title Format

<type>(<scope>): <description>

Types (same as Conventional Commits):

Type Description
feat New feature
fix Bug fix
docs Documentation only
style Code style changes
refactor Code refactoring
perf Performance improvement
test Add or modify tests
chore Build process or tools
ci CI/CD configuration
build Build system changes

Scope: Optional, indicates affected module (e.g., devflow, blocklet, auth)

Description:

  • Imperative mood ("add" not "added")
  • Lowercase first letter
  • No period at end
  • Under 72 characters

Body Format

## Summary

<1-5 bullet points describing key changes>

## Motivation / Context

<Why this change is needed - the problem being solved>

## Changes

<Detailed list of what was changed, organized by area>

## Test Plan

<How to verify the changes work correctly>
- [ ] Step 1
- [ ] Step 2

Workflow

Step 1: Gather Branch Information

# Get current branch name
git branch --show-current

# Get main branch (usually 'main' or 'master')
git remote show origin | grep 'HEAD branch' | cut -d' ' -f5

# Check if branch is pushed to remote
git status -sb

Step 2: Analyze All Commits and Changes

IMPORTANT: Analyze ALL commits from branch divergence point, not just the latest commit.

# Get the merge base (where current branch diverged from main)
git merge-base main HEAD

# View all commits since diverging from main
git log main..HEAD --oneline

# Get comprehensive diff statistics
git diff main...HEAD --stat

# Get full diff for content analysis
git diff main...HEAD

Step 3: Generate PR Content

Based on the diff analysis:

  1. Determine type: Look at the nature of changes

    • New files/features → feat
    • Bug fixes → fix
    • Only .md files → docs
    • Only test files → test
    • Configuration/tooling → chore

  2. Identify scope: Look at which module/area is most affected

  3. Use project template if exists: If Step 0 found a PR template:

    • Read the template file
    • Fill in each section according to the template's structure
    • Keep all checkboxes from the template (check appropriate ones based on changes)
    • Respect the template's language (Chinese/English)
    • Follow any instructions in HTML comments

  4. Otherwise use default template:

    • Write summary: Capture the essence of ALL commits, not just one
    • Document motivation: Explain why these changes are needed
    • List changes: Organize by logical groupings
    • Create test plan: Practical verification steps

Step 4: Present PR Draft and Ask User

Display the generated PR title and body to the user, then use AskUserQuestion to determine next action:

{
  "questions": [{
    "question": "How would you like to proceed with this PR?",
    "header": "PR Action",
    "options": [
      {"label": "Save as PR.md (Recommended)", "description": "Save PR content to PR.md file in project root (will overwrite if exists)"},
      {"label": "Submit via gh", "description": "Create PR directly using GitHub CLI"}
    ],
    "multiSelect": false
  }]
}

Step 5A: If "Save as PR.md"

Write the PR content to ./PR.md in the project root:

# PR Title

<type>(<scope>): <description>

Inform user that PR.md has been created (or overwritten if it existed).

Step 5B: If "Submit via gh"

5B.1: Check gh CLI availability

which gh

If gh is not found:

GitHub CLI (gh) is not installed. Please install it:

- macOS: brew install gh
- Linux: See https://github.com/cli/cli/blob/trunk/docs/install_linux.md
- Windows: winget install --id GitHub.cli

After installation, run: gh auth login

5B.2: Check gh authentication

gh auth status

If not authenticated or token lacks permissions:

GitHub CLI is not authenticated or lacks permissions. Please run:

gh auth login

Select:
- GitHub.com
- HTTPS
- Authenticate with browser (recommended)

Ensure you grant 'repo' scope for creating PRs.

5B.3: Check if branch is pushed

git status -sb

If branch is not pushed to remote:

# Push current branch to origin
git push -u origin $(git branch --show-current)

5B.4: Create the PR

gh pr create --base main --title "<title>" --body "$(cat <<'EOF'
<body content>
EOF
)"

5B.5: Report Success

Display the PR URL and summary to the user.

Example Output

Title

feat(devflow): add PR generation skill

Body

## Summary

- Add new `pull-request` skill for generating standardized Pull Requests
- Analyze diff between current branch and main branch
- Support both gh CLI submission and PR.md file generation
- Include comprehensive PR template based on best practices

## Motivation / Context

Creating consistent, well-documented PRs is important for code review efficiency.
This skill automates PR generation by analyzing git diff and following established patterns.

## Changes

### New Files
- `.claude/skills/pull-request/SKILL.md` - Pull Request generation skill definition

### Workflow
- Step 1: Gather branch and diff information
- Step 2: Analyze all commits since branch divergence
- Step 3: Generate PR content following template
- Step 4: Ask user for submission method
- Step 5: Execute chosen action (gh submit or save to file)

## Test Plan

- [ ] Run `/pull-request` on a feature branch with changes
- [ ] Verify PR title follows conventional commit format
- [ ] Verify summary captures all changes
- [ ] Test gh submission flow
- [ ] Test PR.md generation flow

Example Output (With Project Template)

When project has .github/PULL_REQUEST_TEMPLATE.md, fill in that template instead:

Title

feat(test): add coverage merge and reporting support

Body (following project template structure)

### 关联 Issue

related: https://github.com/example/repo/issues/123

### 主要改动

1. 新增 `--coverage` 参数支持测试覆盖率收集
2. 创建 `merge-coverage.js` 脚本合并所有子包的覆盖率报告
3. 重新启用 CI 覆盖率报告功能
4. 排除编译后和自动生成的文件以获得准确的覆盖率统计

Rules

  1. Always check for project PR template first - Look for .github/PULL_REQUEST_TEMPLATE.md before generating content
  2. Use project template if exists - Follow the project's PR template structure, language, and checkboxes
  3. Always analyze ALL commits from branch divergence point, not just HEAD
  4. Follow Conventional Commits format for title
  5. Keep title under 72 characters
  6. Include test plan with actionable verification steps
  7. Base PR on main branch (or project's default branch)
  8. Check gh auth before attempting to create PR
  9. Push branch first if not already pushed to remote
  10. Preserve user's intent - ask before overwriting existing PR.md
  11. Respect template language - If project template is in Chinese, write PR body in Chinese
