name: PR Workflow description: Use this skill when the user wants to "create PR", "update PR", "merge PR", "PR template", "auto-fill PR", "request review", or manage pull request lifecycle. Generates PR descriptions from commits/issues with intelligent defaults. version: 0.1.0

PR Workflow

Complete PR lifecycle management with auto-generated descriptions from commits and issues.

Purpose

PR Workflow provides systematic pull request management with intelligent description generation, template selection based on work type, and automated review requests.

When to Use

• Creating PRs with auto-generated descriptions
• Using templates based on work type (feature/fix/chore/docs/refactor)
• Updating PR metadata (reviewers, labels, milestones)
• Managing PR lifecycle (draft → ready → merge)

Core Capabilities

PR Creation with Auto-Description

Copy# Get commits since base branch
COMMITS=$(git log main..HEAD --oneline --no-decorate)

# Get linked issue
BRANCH=$(git branch --show-current)
ISSUE=$(extractIssueNumber "$BRANCH")

# Generate description
DESC=$(generatePRDescription "$COMMITS" "$ISSUE")

# Create PR
gh pr create --title "Add authentication system" --body "$DESC"

Utilities:

• generatePRDescription(commits, linkedIssue?) - Auto-generate from commits
• getPRTemplateByWorkType(workType) - Get template by type
• renderPRTemplate(template, vars) - Substitute variables
• groupCommitsByType(commits) - Group by conventional commit types
• formatGroupedCommits(grouped) - Format as sections

Template Selection

Templates automatically adapt to work type:

Feature PR:

Copy## Summary
Brief overview

## Changes
- Change 1
- Change 2

## Testing
- [ ] Unit tests
- [ ] Integration tests

## Related Issues
Closes #42

Bug Fix PR:

Copy## Bug Fix
Brief description

## Root Cause
What caused it

## Solution
How we fixed it

## Testing
- [ ] Bug reproduced before fix
- [ ] Bug resolved after fix

Review Requests

Copy# Auto-request reviewers from CODEOWNERS
OWNERS=$(grep "^$(dirname $FILE)" .github/CODEOWNERS | awk '{print $2}')

gh pr edit $PR --add-reviewer "$OWNERS"

# Or manually
gh pr edit $PR --add-reviewer @user1,@user2

PR Updates

Copy# Update labels
gh pr edit 42 --add-label "enhancement,priority:high"

# Update milestone
gh pr edit 42 --milestone "v2.0"

# Convert to draft
gh pr ready --undo 42

# Mark ready for review
gh pr ready 42

Templates

• getFeaturePRTemplate() - New features
• getBugfixPRTemplate() - Bug fixes
• getChorePRTemplate() - Maintenance
• getDocsPRTemplate() - Documentation
• getRefactorPRTemplate() - Code improvements

All templates include:

• Summary section
• Change list
• Testing checklist
• Related issues
• Claude Code footer

Examples

Create PR with Grouped Commits

Copy# Get commits
COMMITS=$(git log main..HEAD --pretty=format:"%s")

# Group by type
GROUPED=$(groupCommitsByType "$COMMITS")
# Returns: { feat: [...], fix: [...], docs: [...] }

# Format as sections
BODY=$(formatGroupedCommits "$GROUPED")

# Add issue reference
ISSUE=$(extractIssueNumber "$(git branch --show-current)")
BODY="$BODY

## Related Issues

Closes #$ISSUE"

# Create PR
gh pr create --title "Authentication system" --body "$BODY"

Auto-Merge When CI Passes

Copy# Create PR and enable auto-merge
PR=$(gh pr create --title "..." --body "..." --json number -q .number)

# Enable auto-merge (squash)
gh pr merge $PR --auto --squash --delete-branch

# CI will auto-merge when checks pass

Request Reviews from CODEOWNERS

Copy# Parse CODEOWNERS for file
FILE="src/auth/login.ts"
PATTERN=$(grep -E "^[^#].*$(dirname $FILE)" .github/CODEOWNERS | head -1)
REVIEWERS=$(echo "$PATTERN" | awk '{for(i=2;i<=NF;i++) print $i}' | tr '\n' ',' | sed 's/,$//')

# Request review
gh pr edit $PR --add-reviewer "$REVIEWERS"

Best Practices

1. Auto-generate descriptions from commits
2. Use conventional commits for grouping (feat:, fix:, etc.)
3. Link to issues with "Closes #N"
4. Request reviews from CODEOWNERS
5. Use templates matching work type
6. Enable auto-merge for simple PRs
7. Add preview URLs to description
