PR Creation

This skill MUST be invoked whenever you are creating a pull request. It handles the complete workflow from context gathering to PR submission with consistent formatting.

When This Skill Activates

Auto-invoke this skill when the user implies a PR should be created:

Key insight: If the user's intent results in gh pr create being run, this skill MUST be used first.

Do NOT run gh pr create without this skill.

Complete PR Creation Workflow

Step 1: Gather Context

git status                              # Check working tree state
git diff HEAD                           # See uncommitted changes (if any)
git log main..HEAD --oneline            # Commits to be included in PR
git diff main...HEAD                    # Full diff against base branch
git branch --show-current               # Current branch name

Important: Ensure all changes are committed before creating PR. If uncommitted changes exist, use the git-commit-validator skill first.

Step 2: Determine Base Branch

Check for common base branch names:

git rev-parse --verify main 2>/dev/null && echo "main" || git rev-parse --verify master 2>/dev/null && echo "master"

Or check remote default:

gh repo view --json defaultBranchRef --jq '.defaultBranchRef.name'

Step 3: Generate PR Title

Format: type(scope): description (conventional commits)

Rules:

• Max 50 characters
• Lowercase type from: feat, fix, docs, refactor, test, chore, perf, ci, build, style, revert
• Optional scope in parentheses
• Imperative mood ("add" not "added")
• No period at end

Title should summarize the entire PR, not just the last commit.

Analyze all commits in the PR:

git log main..HEAD --oneline

Synthesize into a single title that captures the overall change.

Step 4: Generate PR Body

Use this exact format:

## Summary
[1-3 sentences explaining what this PR does and why]

## Changes
- [Bullet list of key changes]
- [Focus on what matters, not every file touched]

## Test Plan
[How changes were validated - tests run, manual verification, etc.]

Closes #123

Body Guidelines:

• Summary: Brief context for reviewers, focus on WHY
• Changes: Key modifications, not exhaustive file list
• Test Plan: How you verified the changes work
• Issue reference: Include if applicable (Closes, Fixes, Resolves)

Step 5: Create PR

Default: Create as draft (per project standards)

Use HEREDOC for proper body formatting:

gh pr create --draft --title "type(scope): description" --body "$(cat <<'EOF'
## Summary
Brief explanation of what and why.

## Changes
- Key change 1
- Key change 2

## Test Plan
How this was tested.

Closes #123
EOF
)"

For ready-for-review PRs (when user explicitly requests):

gh pr create --title "..." --body "..."

Validation Rules

Title Validation

1. Max 50 characters - Truncate or rephrase if over
2. Format check - Must match: ^[a-z]+(\([a-z0-9\-]+\))?!?:.+$
3. Valid type - One of: feat, fix, docs, refactor, test, chore, perf, ci, build, style, revert
4. Imperative mood - "add feature" not "added feature"
5. No period at end

Body Validation

1. Has Summary section - Required
2. Has Changes section - Required (at least one bullet)
3. Has Test Plan section - Required
4. Concise - 2-3 paragraphs max in summary
5. No AI attribution - No "Generated by", "Created with AI", etc.

Pre-flight Checks

Before creating PR:

1. Branch has commits ahead of base
2. No uncommitted changes (or commit them first)
3. Branch is pushed to remote
4. No existing PR for this branch (unless intentional)

# Check if PR already exists
gh pr list --head "$(git branch --show-current)" --state open

Why Draft by Default?

Draft PRs signal the work is ready for early feedback but may not be complete. Benefits:

• Allows CI to run before requesting reviews
• Enables async collaboration on in-progress work
• Prevents accidental merges of incomplete work
• Clear signal when ready: mark ready for review

To create a non-draft PR, user must explicitly request it.
