Pr Worktree Manager

PR Worktree Manager

Overview

This skill manages the complete lifecycle of feature development using git worktrees, from creation through PR merge and cleanup. It provides automation, best practices, and safety checks for a professional development workflow.

When to Use This Skill

Claude should use this skill when the user:

• Wants to create a new feature branch with worktree
• Mentions "create worktree" or "new feature branch"
• Asks about PR workflow or best practices
• Wants to clean up after PR merge
• Needs help managing multiple worktrees
• Asks "how do I work on multiple features"
• Mentions "delete worktree" or "cleanup branch"

Workflow Phases

Phase 1: Feature Setup (Create Worktree)

When: User wants to start a new feature

Process:

1. Understand Requirements

   • Ask feature name (kebab-case preferred)
   • Confirm base branch (usually main)
   • Determine worktree location preference

2. Pre-Creation Checks

   # Verify we're in a git repository
   git status
   
   # Check current worktrees
   git worktree list
   
   # Ensure base branch is up to date
   git fetch origin
   git checkout main
   git pull origin main
   

3. Create Worktree

   # Format: git worktree add <path> -b <branch-name>
   git worktree add ../<project-name>-<feature-name> -b <feature-name>
   

   Example:

   git worktree add ../trustie-mobile-FE-authentication -b feature/authentication
   

4. Verify Creation

   # List all worktrees
   git worktree list
   
   # Navigate to new worktree
   cd ../<project-name>-<feature-name>
   
   # Verify branch
   git branch --show-current
   

5. Initial Setup (if needed)

   • Run npm install or equivalent
   • Create initial commit if needed
   • Push branch to remote: git push -u origin <branch-name>

Phase 2: Development

When: User is actively working in the feature worktree

Guidance:

1. Work normally in the feature worktree
2. Commit changes regularly
3. Push to remote branch frequently
4. Keep feature branch updated with main (if needed):

   git fetch origin
   git rebase origin/main
   # or
   git merge origin/main
   

Phase 3: Create Pull Request

When: Feature is ready for review

Process:

1. Pre-PR Checks

   # Ensure all changes are committed
   git status
   
   # Verify tests pass (if applicable)
   npm test
   
   # Ensure branch is pushed
   git push origin <branch-name>
   

2. Create PR

   # Using GitHub CLI (recommended)
   gh pr create --title "Feature: <description>" --body "<detailed description>"
   
   # Or provide URL for manual creation
   echo "Create PR at: https://github.com/<owner>/<repo>/compare/<branch-name>"
   

3. PR Best Practices

   • Write clear title and description
   • Link to relevant issues
   • Request specific reviewers
   • Add labels/milestones
   • Include testing instructions

Phase 4: Review & Updates

When: PR needs changes based on feedback

Process:

1. Make changes in the feature worktree
2. Commit changes
3. Push to remote (PR updates automatically):

   git add .
   git commit -m "Address review feedback: <description>"
   git push origin <branch-name>
   

Phase 5: Cleanup After Merge

When: PR has been merged, time to clean up

IMPORTANT: Always clean up after PR merge to:

• Reclaim disk space (~2GB per worktree)
• Keep git status clean
• Remove stale branches
• Maintain professional workflow

Complete Cleanup Process:

# Step 1: Navigate to main worktree
cd /path/to/main/worktree

# Step 2: Update main branch with merged changes
git checkout main
git pull origin main

# Step 3: Verify the merge is in main
git log --oneline -10  # Should see your commits

# Step 4: Remove the feature worktree
git worktree remove ../project-name-feature-name

# If it complains about uncommitted changes:
git worktree remove --force ../project-name-feature-name

# Step 5: Delete local branch
git branch -d feature-name

# If not fully merged (rare after PR merge):
git branch -D feature-name  # Force delete

# Step 6: Delete remote branch
# Method A (easiest): Via GitHub UI
# On the PR page, click "Delete branch" button

# Method B: Via command line
git push origin --delete feature-name

# Step 7: Prune stale references
git fetch --prune

# Step 8: Clean up directory (if still exists)
rm -rf ../project-name-feature-name

# Step 9: Verify clean state
git worktree list  # Should not show removed worktree
git branch -a      # Should not show deleted branches

Quick Cleanup One-Liner (for advanced users):

cd /path/to/main/worktree && \
git checkout main && \
git pull origin main && \
git worktree remove ../worktree-name --force && \
git branch -d branch-name && \
git fetch --prune && \
rm -rf ../worktree-name

Then delete remote branch via GitHub UI.

Troubleshooting

Problem: "worktree remove" fails with uncommitted changes

Solution:

cd /path/to/feature/worktree
git status

# Option 1: Commit them
git add -A
git commit -m "Final changes"
git push

# Option 2: Discard them
git reset --hard HEAD

# Option 3: Force remove
cd /path/to/main/worktree
git worktree remove --force ../feature-worktree

Problem: "Cannot delete branch - not fully merged"

Solution:

# Verify branch is actually merged
git branch --merged main | grep feature-name

# If truly merged, force delete
git branch -D feature-name

# For remote
git push origin --delete feature-name --force

Problem: Worktree directory still exists after removal

Solution:

# Manually delete
rm -rf /path/to/worktree-directory

# Clean up git's internal worktree list
git worktree prune

Problem: Multiple worktrees, confused which is which

Solution:

# List all worktrees with branches
git worktree list

# Shows:
# /path/to/main     [main]
# /path/to/feature  [feature-branch]

Best Practices

Naming Conventions

Branch Names:

• Use descriptive names: feature/authentication, fix/login-bug
• Use kebab-case: feature-name, not feature_name or FeatureName
• Prefix with type: feature/, fix/, refactor/, docs/

Worktree Directory Names:

• Match project pattern: project-name-feature-name
• Keep as siblings to main worktree: ../project-name-feature
• Example: If main is trustie-mobile-FE, feature could be trustie-mobile-FE-authentication

Workflow Tips

1. One Feature, One Worktree: Don't try to work on multiple features in one worktree
2. Keep Main Worktree Clean: Always work on features in separate worktrees
3. Delete Promptly: Clean up worktrees immediately after PR merge
4. Use GitHub UI for Remote Deletion: Easiest and safest method
5. Verify Before Deleting: Always check git log to confirm merge before cleanup

Storage Management

• Each worktree duplicates: node_modules, builds, .git data (~2GB)
• Maximum recommended: 2-3 active worktrees
• Clean up merged PRs within 24 hours
• Use git worktree list regularly to track active worktrees

Common Workflows

Starting a New Feature

User says: "I want to work on a new authentication feature"

Claude does:

1. Ask for confirmation on feature name
2. Check current worktrees
3. Create worktree with branch
4. Navigate to new worktree
5. Provide next steps

Cleaning Up After Merge

User says: "My PR was just merged, clean it up"

Claude does:

1. Verify PR is merged (check GitHub)
2. Update main branch
3. Run cleanup sequence
4. Verify clean state
5. Confirm success

Managing Multiple Features

User says: "I have 3 features in progress, show me status"

Claude does:

1. Run git worktree list
2. For each worktree, show:
   • Branch name
   • Last commit
   • PR status (if applicable)
3. Suggest which can be cleaned up

Quick Reference

Essential Commands

# Create worktree
git worktree add <path> -b <branch-name>

# List worktrees
git worktree list

# Remove worktree
git worktree remove <path>

# Delete branch
git branch -d <branch-name>

# Prune stale references
git fetch --prune
git worktree prune

Workflow Checklist

Creating:

• Main branch is up to date
• Feature name is clear
• Worktree created successfully
• Branch pushed to remote

Cleaning Up:

• PR is merged
• Main branch updated
• Worktree removed
• Local branch deleted
• Remote branch deleted (via GitHub UI)
• References pruned
• Verified clean with git worktree list

When NOT to Use Worktrees

• Quick fixes on current branch
• Simple one-file changes
• Documentation updates
• Reviewing someone else's PR (use gh pr checkout instead)

For simple changes, just work on a branch in your main worktree.

Integration with Other Tools

With GitHub CLI (gh)

# Create PR from worktree
gh pr create

# Check PR status
gh pr status

# Checkout someone's PR
gh pr checkout 123

# Delete branch after merge (from GitHub)
# Use UI's "Delete branch" button on PR page

With VS Code

• Each worktree can be opened as a separate VS Code window
• Settings are shared if using workspace settings
• Extensions work in each worktree independently

With Node/NPM

• Each worktree needs its own node_modules
• Run npm install in new worktrees
• Consider node_modules in .gitignore to avoid committing
