Create PR Skill

Purpose

Create well-structured pull requests that link to originating issues, summarize changes clearly, and facilitate effective code review. This skill analyzes the branch, detects related issues, and generates comprehensive PR descriptions.

Natural Language Triggers

This skill activates when the user says things like:

• "Create a PR"
• "Open a pull request"
• "Make a PR for this work"
• "Submit this for review"
• "I'm ready to create a pull request"
• "PR this branch"
• After work completion: "Done, let's open a PR"

Workflow Execution

Phase 1: Gather Context (Parallel)

Execute these in parallel for efficiency:

1. Project Context:

   • Read project's CLAUDE.md for PR conventions
   • Identify target branch (main, develop, etc.)

2. Branch Analysis:

   • git branch --show-current - Current branch name
   • git log main..HEAD --oneline - Commits on this branch
   • git diff main...HEAD --stat - Change summary

3. Remote Status:

   • Check if branch is pushed to remote
   • Check if remote is up to date

Phase 2: Detect Issue Context

1. Extract Issue Reference from Branch Name:

   Common patterns:

   • 42-feature-description → Issue #42
   • feature/42-description → Issue #42
   • fix/123-bug-name → Issue #123
   • ABC-123-description → Linear issue ABC-123

2. Retrieve Issue Details:

   For GitHub Issues:

   mcp__github__get_issue(owner, repo, issue_number)
   

   • Get title, description, acceptance criteria
   • Get labels for PR labeling
   • Check issue state (should be open)

   For Linear Issues:

   mcp__linear__get_issue(id)
   

   • Get issue details and context

3. Build Context Map:

   • Original issue requirements
   • Acceptance criteria to verify
   • Related issues (blocks, depends on)
   • Milestone/project context

Phase 3: Analyze Changes

1. Commit Analysis:

   • Review each commit message
   • Identify modules affected
   • Categorize change types (feat, fix, etc.)

2. Change Summary:

   • Files changed and why
   • Key functionality added/modified
   • Breaking changes (if any)

3. Verify Completeness:

   • Do commits address the issue requirements?
   • Are acceptance criteria met?
   • Any outstanding work?

Phase 4: Generate PR Content

PR Title: Format: {type}: {description} (#{issue_number})

Example: feat: Add commit-changes skill (#42)

PR Description Template:

## Summary
{Brief explanation aligned with original issue goals}

## Issue Resolution
Closes #{issue_number}

{How this implementation addresses the original requirements}

## Key Changes
- {Module-focused change descriptions}
- {New capabilities enabled}
- {Breaking changes if any}

## Implementation Notes
{Any deviations from issue description}
{Technical decisions made}
{Trade-offs considered}

## Testing
{How this was tested}
{What testing is appropriate for current project phase}

## Checklist
- [ ] Code follows project conventions
- [ ] Changes are atomic and reviewable
- [ ] Documentation updated (if needed)
- [ ] Tests added/updated (if applicable)

Phase 5: Confirm with User

Use AskUserQuestion to confirm PR details:

AskUserQuestion:
  question: "Ready to create this PR?"
  header: "Create PR"
  options:
    - label: "Yes, create PR"
      description: "Create the PR with this title and description"
    - label: "Edit title"
      description: "I want to modify the PR title"
    - label: "Edit description"
      description: "I want to modify the PR description"
    - label: "Create as draft"
      description: "Create as draft PR (not ready for review)"
    - label: "Cancel"
      description: "Don't create PR right now"

Display the proposed title and description before asking.

Phase 6: Create Pull Request

1. Ensure branch is pushed:

   git push -u origin {branch-name}
   

2. Create PR using gh CLI:

   gh pr create \
     --title "{title}" \
     --body "$(cat <<'EOF'
   {PR description}
   EOF
   )" \
     --base {target-branch}
   

   Or use MCP GitHub tools:

   mcp__github__create_pull_request(...)
   

3. Apply labels (from issue + modules affected)

4. Link to issue (auto-close on merge via "Closes #X")

Phase 7: Report Result

Display:

✓ Pull Request created!

🔗 PR #XX: {title}
   {PR URL}

📋 Linked to Issue #{issue_number}

👀 Ready for review
   Target: {target-branch}
   Reviewers: {if any suggested}

Auto-Configuration

Based on context, automatically determine:

1. Target Branch:

   • Check CLAUDE.md for project conventions
   • Default: main or develop (whichever exists)

2. Labels:

   • From originating issue
   • From modules affected (if label mapping exists)
   • Change type (enhancement, bug, etc.)

3. Draft Status:

   • Set draft if branch contains "wip" or "draft"
   • Set draft if issue is incomplete
   • Ask user if uncertain

4. Reviewers:

   • Suggest based on CODEOWNERS
   • Suggest based on issue assignees
   • Suggest based on module ownership

Error Handling

No Commits on Branch

ℹ️ No commits to create PR from.
   Branch has no changes vs {target-branch}.

Branch Not Pushed

📤 Branch not on remote. Pushing now...
   git push -u origin {branch}

Issue Not Found

⚠️ Could not find issue reference in branch name.
   Branch: {branch-name}

   Would you like to:
   1. Enter issue number manually
   2. Create PR without issue link
   3. Cancel

PR Already Exists

ℹ️ PR already exists for this branch.
   🔗 PR #{number}: {title}

   Would you like to update it instead?

Integration with Other Skills

Follows:

• work-session skill - After completing all tasks
• commit-changes skill - After final commit

Links to:

• GitHub Issues - Auto-close on merge
• Linear Issues - Link and track

Best Practices

✅ DO:

• Link PRs to originating issues
• Write clear, context-rich descriptions
• Include testing information
• Note any deviations from original requirements
• Use conventional PR titles

❌ DON'T:

• Create PRs for incomplete work (use draft instead)
• Skip the issue link
• Write vague descriptions
• Include unrelated changes
• Force push after PR is created (without warning)
