Creating Pr

⚠️ CRITICAL CONSTRAINTS

No Claude Code Footer Policy

YOU MUST NEVER add Claude Code attribution to pull requests.

• ❌ NO "🤖 Generated with [Claude Code]" in PR titles or descriptions
• ❌ NO "Co-Authored-By: Claude noreply@anthropic.com" in PR content
• ❌ NO Claude Code attribution, footer, or branding of any kind

Pull requests are public code review documents and must remain clean and professional.

GitHub PR Creation Workflow

Execute GitHub Pull Request workflows with automatic repository detection, branch management, and intelligent PR content generation.

Usage

This skill is invoked when:

• User runs /create-pr or /git:create-pr command
• User requests to create a pull request
• User asks to open a PR or push changes for review

How It Works

This skill handles the complete PR workflow:

1. Repository Detection - Detect current repository context (root or submodule)
2. Branch Validation - Verify not on protected branch, check for uncommitted changes
3. Branch Pushing - Ensure branch exists on remote
4. Existing PR Detection - Check if PR already exists for current branch
5. PR Content Generation - Create title and description from commits
6. PR Creation - Create or update PR using GitHub CLI

Supported Arguments

Parse arguments from user input:

• No arguments: Auto-detect repository and create PR to main branch
• <scope>: Direct PR for specific repository (root, submodule-name)
• --draft: Create as draft PR
• --base <branch>: Target branch (default: main)
• Combinations: <scope> --draft, root --base staging, etc.

Prerequisites

GitHub CLI Required: Must have gh installed and authenticated

# Install GitHub CLI (if not installed)
# macOS: brew install gh
# Linux: See https://cli.github.com/

# Authenticate
gh auth login

PR Creation Workflow Steps

Step 1: Parse Arguments

Extract scope, draft flag, and base branch from user input:

# Parse arguments
SCOPE=""
DRAFT_FLAG=""
BASE_BRANCH="main"

# Example parsing:
# "root --draft" → SCOPE="root", DRAFT_FLAG="--draft", BASE_BRANCH="main"
# "--base staging" → SCOPE="", DRAFT_FLAG="", BASE_BRANCH="staging"
# "my-service --draft --base develop" → SCOPE="my-service", DRAFT_FLAG="--draft", BASE_BRANCH="develop"

Step 2: Detect Repository Context

Find monorepo root and determine current repository:

# Find monorepo root (handles submodules)
if SUPERPROJECT=$(git rev-parse --show-superproject-working-tree 2>/dev/null) && [ -n "$SUPERPROJECT" ]; then
    # We're in a submodule
    MONOREPO_ROOT="$SUPERPROJECT"
else
    # We're in root or standalone repo
    MONOREPO_ROOT=$(git rev-parse --show-toplevel)
fi

# Get current working directory
CURRENT_DIR=$(pwd)

# Determine repository context
if [ -n "$SCOPE" ]; then
    # User specified scope
    if [ "$SCOPE" = "root" ]; then
        REPO_PATH="$MONOREPO_ROOT"
    else
        REPO_PATH="$MONOREPO_ROOT/$SCOPE"
    fi
else
    # Auto-detect from current directory
    # If in submodule, use submodule path
    # If in root, use root path
    if [[ "$CURRENT_DIR" == "$MONOREPO_ROOT" ]]; then
        REPO_PATH="$MONOREPO_ROOT"
    else
        # Find which submodule we're in
        REPO_PATH=$(git -C "$CURRENT_DIR" rev-parse --show-toplevel)
    fi
fi

# Validate repository
if [ ! -d "$REPO_PATH/.git" ]; then
    echo "❌ Error: Not a valid git repository: $REPO_PATH" >&2
    exit 1
fi

Step 3: Validate Branch State

Check current branch and uncommitted changes:

# Change to repository directory
cd "$REPO_PATH"

# Get current branch
CURRENT_BRANCH=$(git rev-parse --abbrev-ref HEAD)

# Check if on protected branch
if [ "$CURRENT_BRANCH" = "main" ] || [ "$CURRENT_BRANCH" = "master" ]; then
    echo "❌ Cannot create PR from protected branch: $CURRENT_BRANCH" >&2
    echo "" >&2
    echo "Please create a feature branch first:" >&2
    echo "  git checkout -b feature/your-feature-name" >&2
    echo "" >&2
    exit 1
fi

# Check for uncommitted changes
UNCOMMITTED=$(git status --porcelain)
if [ -n "$UNCOMMITTED" ]; then
    echo "❌ Error: You have uncommitted changes" >&2
    echo "" >&2
    echo "Please commit or stash your changes before creating a PR:" >&2
    git status --short
    echo "" >&2
    exit 1
fi

# Check if branch has commits ahead of base
COMMITS_AHEAD=$(git rev-list --count "$BASE_BRANCH..HEAD" 2>/dev/null || echo "0")
if [ "$COMMITS_AHEAD" = "0" ]; then
    echo "❌ Error: No commits to create PR from" >&2
    echo "Current branch '$CURRENT_BRANCH' has no commits ahead of '$BASE_BRANCH'" >&2
    exit 1
fi

echo "ℹ️  Branch: $CURRENT_BRANCH ($COMMITS_AHEAD commits ahead of $BASE_BRANCH)"

Step 4: Push Branch to Remote

Ensure branch exists on remote:

# Check if branch exists on remote
REMOTE_BRANCH=$(git ls-remote --heads origin "$CURRENT_BRANCH" 2>/dev/null)

if [ -z "$REMOTE_BRANCH" ]; then
    echo "ℹ️  Branch not on remote, pushing..."
    git push -u origin "$CURRENT_BRANCH" || {
        echo "❌ Failed to push branch to remote" >&2
        exit 1
    }
    echo "✅ Branch pushed to origin/$CURRENT_BRANCH"
else
    # Check if local is behind remote
    LOCAL_HASH=$(git rev-parse HEAD)
    REMOTE_HASH=$(git rev-parse "origin/$CURRENT_BRANCH" 2>/dev/null || echo "")

    if [ "$LOCAL_HASH" != "$REMOTE_HASH" ]; then
        echo "ℹ️  Local branch differs from remote, pushing..."
        git push origin "$CURRENT_BRANCH" || {
            echo "❌ Failed to push branch to remote" >&2
            exit 1
        }
        echo "✅ Branch updated on remote"
    else
        echo "ℹ️  Branch already up to date on remote"
    fi
fi

Step 5: Check for Existing PR

Detect if PR already exists for this branch:

# Check for existing PR using GitHub CLI
EXISTING_PR=$(gh pr view "$CURRENT_BRANCH" --json number,title,url 2>/dev/null || echo "")

if [ -n "$EXISTING_PR" ]; then
    # PR exists - extract info
    PR_NUMBER=$(echo "$EXISTING_PR" | jq -r '.number')
    PR_TITLE=$(echo "$EXISTING_PR" | jq -r '.title')
    PR_URL=$(echo "$EXISTING_PR" | jq -r '.url')

    echo ""
    echo "ℹ️  Existing PR found:"
    echo "  #$PR_NUMBER: $PR_TITLE"
    echo "  $PR_URL"
    echo ""

    # Use AskUserQuestion to ask user what to do
    # Options:
    # 1. Update PR (regenerate title/body and update)
    # 2. View PR in browser (open URL)
    # 3. Cancel (do nothing)

    # If user chooses "Update PR":
    # - Generate new title and body (Steps 6-7)
    # - Update PR using: gh pr edit "$PR_NUMBER" --title "..." --body "..."
    # - Show success message

    # If user chooses "View PR":
    # - Open PR URL in browser: gh pr view --web

    # If user chooses "Cancel":
    # - Exit gracefully
fi

Step 6: Generate PR Title

Analyze commits to create conventional PR title:

# Get all commits from base branch to current branch
COMMITS=$(git log "$BASE_BRANCH..HEAD" --oneline)
COMMIT_COUNT=$(echo "$COMMITS" | wc -l | tr -d ' ')

echo "ℹ️  Analyzing $COMMIT_COUNT commits..."

# Get the first commit message (most recent)
LATEST_COMMIT=$(git log -1 --pretty=%B)

# Detect commit type from latest commit or analyze all commits
# Try to extract type from conventional commit format
if echo "$LATEST_COMMIT" | grep -qE '^(feat|fix|docs|refactor|test|chore|perf|ci|build):'; then
    # Extract type and description from conventional commit
    COMMIT_TYPE=$(echo "$LATEST_COMMIT" | grep -oE '^[a-z]+' | head -1)
    COMMIT_DESC=$(echo "$LATEST_COMMIT" | sed -E 's/^[a-z]+(\([^)]+\))?:\s*//')
else
    # Analyze changes to determine type
    ALL_COMMITS=$(git log "$BASE_BRANCH..HEAD" --pretty=%B)

    if echo "$ALL_COMMITS" | grep -qi "fix\|bug"; then
        COMMIT_TYPE="fix"
    elif echo "$ALL_COMMITS" | grep -qi "feat\|feature\|add"; then
        COMMIT_TYPE="feat"
    elif echo "$ALL_COMMITS" | grep -qi "docs\|documentation"; then
        COMMIT_TYPE="docs"
    elif echo "$ALL_COMMITS" | grep -qi "refactor"; then
        COMMIT_TYPE="refactor"
    elif echo "$ALL_COMMITS" | grep -qi "test"; then
        COMMIT_TYPE="test"
    else
        COMMIT_TYPE="feat"
    fi

    # Generate description from branch name or commit
    COMMIT_DESC=$(echo "$LATEST_COMMIT" | head -1 | sed 's/^\s*//')
fi

# Generate PR title (capitalize first letter)
PR_TITLE="$COMMIT_TYPE: $COMMIT_DESC"

echo "ℹ️  Generated PR title: $PR_TITLE"

Step 7: Generate PR Body

Create PR description with summary and test plan:

# Generate PR body with summary from commits
PR_BODY="## Summary

"

# Add commit summaries
if [ "$COMMIT_COUNT" -eq 1 ]; then
    # Single commit - use full message
    PR_BODY+="$LATEST_COMMIT

"
else
    # Multiple commits - list them
    PR_BODY+="This PR includes $COMMIT_COUNT commits:

"
    while IFS= read -r commit; do
        PR_BODY+="- $commit
"
    done <<< "$COMMITS"
    PR_BODY+="
"
fi

# Add test plan section
PR_BODY+="## Test Plan

- [ ] Code builds successfully
- [ ] Tests pass
- [ ] Manual testing completed
- [ ] Documentation updated (if needed)

## Changes

"

# List changed files
CHANGED_FILES=$(git diff --name-only "$BASE_BRANCH..HEAD")
while IFS= read -r file; do
    PR_BODY+="- \`$file\`
"
done <<< "$CHANGED_FILES"

echo ""
echo "Generated PR description:"
echo "━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━"
echo "$PR_BODY"
echo "━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━"
echo ""

Step 8: Create PR

Use GitHub CLI to create the PR:

# IMPORTANT: No Claude Code attribution in PR content

# Build gh pr create command
GH_CMD="gh pr create --title \"$PR_TITLE\" --body \"$PR_BODY\" --base \"$BASE_BRANCH\""

# Add draft flag if specified
if [ "$DRAFT_FLAG" = "--draft" ]; then
    GH_CMD+=" --draft"
fi

# Execute PR creation
eval "$GH_CMD" || {
    echo "❌ Failed to create PR" >&2
    exit 1
}

# Get PR URL
PR_URL=$(gh pr view --json url -q '.url')

echo ""
echo "✅ Pull Request created successfully!"
echo ""
echo "PR URL: $PR_URL"
echo ""
echo "Next steps:"
echo "  - Review PR in browser: gh pr view --web"
echo "  - Check CI status: gh pr checks"
echo "  - Request reviews: gh pr ready (if draft)"
echo ""

Alternative: Update Existing PR

If updating an existing PR (user chose "Update" in Step 5):

# Update PR title and body
gh pr edit "$PR_NUMBER" --title "$PR_TITLE" --body "$PR_BODY" || {
    echo "❌ Failed to update PR" >&2
    exit 1
}

echo "✅ Pull Request #$PR_NUMBER updated successfully!"
echo "PR URL: $PR_URL"

PR Title Generation Rules

The skill generates PR titles following conventional commit format:

Important Notes

1. GitHub CLI Required: Must have gh installed and authenticated

   gh auth login
   

2. Branch Protection: Cannot create PR from main/master branch

3. Existing PRs: Automatically detects and offers to update existing PRs

4. Commit-Based Content: PR title and body generated from commit messages

5. Works Anywhere: Executes from any directory, resolves paths absolutely

6. Submodule Support: Can create PRs for both root repository and submodules

7. Clean PR Content: No Claude Code attribution in PR titles or descriptions

GitHub CLI Commands Used

This skill uses the following gh commands:

# Check for existing PR
gh pr view <branch> --json number,title,url

# Create new PR
gh pr create --title "..." --body "..." --base <branch> [--draft]

# Update existing PR
gh pr edit <number> --title "..." --body "..."

# View PR in browser
gh pr view --web

# Check PR status
gh pr checks
