Create Pr Agent Skill

Create PR

Generate GitHub pull request descriptions using the PR template at .github/PULL_REQUEST_TEMPLATE.md and referencing changes in the current branch. Outputs markdown and copies to clipboard.

When to Use

Activate this skill when the user:

• Uses /create-pr command with or without a repo name
• Says "create a PR description", "generate PR body", "make a pull request"
• Wants a PR description for their current branch

Important

This skill does NOT:

• ❌ Commit changes
• ❌ Push to remote
• ❌ Create the actual PR on GitHub

This skill ONLY:

• ✅ Generates PR title and description
• ✅ Outputs as markdown
• ✅ Copies to clipboard (platform-specific: pbcopy on macOS, xclip/xsel on Linux, clip.exe on Windows)

Workflow

Step 1: Identify Repository

If repo name is provided:

• Use the specified repository

If no repo name is provided:

• Check for .git in current workspace
• If multiple git repositories detected in workspace, ask user to specify which one

Validation:

• Verify the repository has a remote on GitHub
• Confirm current branch is not main, master, or the default branch

Step 2: Gather Branch Information

Run these commands in the repository directory:

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

# Get the base branch (usually main or master)
git symbolic-ref refs/remotes/origin/HEAD | sed 's@^refs/remotes/origin/@@'

# Get commit history since divergence from base
git log {base-branch}..HEAD --oneline

# Get full diff since divergence
git diff {base-branch}...HEAD

Step 3: Find and Read PR Template

Look for PR template in these locations (in order):

• .github/PULL_REQUEST_TEMPLATE.md
• .github/pull_request_template.md
• docs/PULL_REQUEST_TEMPLATE.md
• docs/pull_request_template.md
• PULL_REQUEST_TEMPLATE.md
• pull_request_template.md

CRITICAL: If template found:

• Read the template file using the Read tool
• Use the EXACT template structure - do not restructure or rename sections
• Preserve HTML comments (<!-- ... -->) - they provide context for reviewers
• Keep all checkbox items exactly as defined in the template
• Only fill in the content areas between section headers
• Do not add sections that don't exist in the template
• Do not remove sections - leave them empty or with "N/A" if not applicable

If no template found:

• Use a generic structure:

  ## Summary
  
  ## Changes
  
  ## Testing
  
  ## Related Issues

Step 4: Analyze Changes

Based on the git diff and commit history:

• Categorize changes:
• New features
• Bug fixes
• Refactoring
• Documentation
• Tests
• Chores

• Identify key files changed:
• List the most significant file changes
• Note any breaking changes or migrations

• Extract commit messages:
• Review commit messages for context
• Identify patterns and themes

Step 5: Fill PR Template

Title Generation:

• Create concise title (50-70 characters max)
• Format: [Type] Brief description
• Types: feat, fix, refactor, docs, test, chore

Body Generation:

IMPORTANT: Follow the repository's template structure exactly.

• Copy the entire template as the starting point
• Keep all HTML comments - they guide reviewers and may be used by automation
• Fill in content below each section header, after any HTML comments
• For checkbox sections:
• Mark applicable items with [x]
• Leave others as [ ]
• Do NOT remove any checkbox items
• For text sections, fill based on:
• Summary/Description: High-level overview of what changed and why
• Changes: Bulleted list of key changes from the diff
• Testing: How to test/verify the changes (use numbered steps)
• Related Issues: Extract from commit messages or branch names. Use short IDs (e.g., "Fixes WOOSHIP-456") NOT full URLs
• Screenshots: Add if UI changes, otherwise write "N/A" or "N/A - Logic fix, no visual changes"

Step 6: Generate Final Output

Format the complete PR content:

## Title

{Generated PR title}

## Description

{Filled PR template body}

Step 7: Copy to Clipboard and Display

• Display the generated PR description to the user in a markdown code block
• Copy to clipboard using the appropriate platform-specific command:

macOS:

   echo "{PR title and body}" | pbcopy

Linux:

   # Using xclip (install: apt-get install xclip or yum install xclip)
   echo "{PR title and body}" | xclip -selection clipboard
   
   # Or using xsel (install: apt-get install xsel or yum install xsel)
   echo "{PR title and body}" | xsel --clipboard --input

Windows (Git Bash/WSL):

   echo "{PR title and body}" | clip.exe

Cross-platform detection example:

   # Detect OS and use appropriate clipboard command
   if command -v pbcopy > /dev/null; then
       echo "{PR title and body}" | pbcopy
   elif command -v xclip > /dev/null; then
       echo "{PR title and body}" | xclip -selection clipboard
   elif command -v xsel > /dev/null; then
       echo "{PR title and body}" | xsel --clipboard --input
   elif command -v clip.exe > /dev/null; then
       echo "{PR title and body}" | clip.exe
   else
       echo "⚠️  No clipboard utility found. Please copy manually."
   fi

• Confirm to user:

   ✅ PR description generated and copied to clipboard!
   
   Next steps:
   1. Push your branch: git push -u origin HEAD
   2. Create PR on GitHub
   3. Paste from clipboard

Repository-Specific Patterns

WooCommerce/woocommerce

• Look for changelog entries
• Check for version bumps
• Verify coding standards compliance

Automattic/woocommerce-connect-server

• Note API changes
• Check for database migrations
• Verify environment variable updates

Automattic/ciab-admin

• Note UI/component changes
• Check for new dependencies
• Verify integration with WC Shipping

woocommerce/woocommerce-shipping

• Check for UDM module changes
• Note carrier integrations
• Verify backward compatibility

Error Handling

No remote configured:

Error: No GitHub remote found. Please configure origin remote first.
Suggestion: git remote add origin https://github.com/{org}/{repo}.git

On default branch:

Error: Cannot create PR from default branch (main/master).
Suggestion: Create a feature branch first: git checkout -b feature/your-branch-name

No changes:

Error: No commits found on this branch compared to {base-branch}.
Suggestion: Make some commits first, or check if you're on the right branch.

Content is in your clipboard - paste into GitHub PR form!

Best Practices

• Be specific: Reference actual code changes, not generic descriptions
• Include context: Why was this change needed? What problem does it solve?
• Testing instructions: Make them actionable and specific
• Link issues: Extract Linear issue IDs and GitHub issue numbers from commits
• Clean output: Format as clean markdown suitable for GitHub

Output Format

Always output in this structure:

## Title
{Generated title}

## Description

{Filled template body}

Then run the appropriate clipboard command for the user's platform (see Step 7 for cross-platform options):

# macOS
echo "{full content}" | pbcopy

# Linux (xclip)
echo "{full content}" | xclip -selection clipboard

# Windows
echo "{full content}" | clip.exe

And tell the user:

✅ PR description generated and copied to clipboard!

Next steps:
1. Push your branch: git push -u origin HEAD
2. Create PR on GitHub
3. Paste description from clipboard

Notes

• This skill does NOT create the PR - it only generates the description
• User must manually push branch and create PR on GitHub
• ALWAYS read the repository's PR template first - do not assume a structure
• Follow the template EXACTLY - preserve HTML comments, section headers, and checkbox items
• Some repos use issue templates in .github/ISSUE_TEMPLATE/ - don't confuse with PR templates
• If commits or branch names reference Linear issues (WOOSHIP-1234, WOO13-143), use the short ID format in "Closes" - NOT the full linear.app URL
• Use platform-appropriate clipboard command (pbcopy on macOS, xclip/xsel on Linux, clip.exe on Windows)
• The clipboard content should be the PR body only (not wrapped in code blocks) - ready to paste directly into GitHub
