description	Create a GitHub Pull Request from the current repository's work.

Create PR Skill

Create a Pull Request from current work with automatic branch creation, commit creation, intelligent remote detection, and PR content generation.

Prerequisites Check (MUST verify first)

Before proceeding, verify:

# 1. Check if in a git repository
git rev-parse --is-inside-work-tree

# 2. Check if gh CLI is available and authenticated
gh auth status

# 3. Record the current working tree state
git status --porcelain

If checks fail, STOP and inform the user:

• Not in git repo → "This skill requires a git repository. Please navigate to a git project."
• gh not authenticated → "Please run gh auth login first."

Do not stop or ask the user to switch branches, commit changes, or stash changes. Handle the current branch and uncommitted changes automatically in the workflow below.

Input

The user may optionally provide:

• Target base branch (defaults to main/master)
• Draft mode flag
• Specific reviewers

Workflow

Step 1: Detect Repository Configuration

# Get all remotes
git remote -v

# Get current branch name
CURRENT_BRANCH=$(git branch --show-current)

# Detect default branch (main or master)
DEFAULT_BRANCH=$(gh repo view --json defaultBranchRef -q '.defaultBranchRef.name')

# Get repository info
gh repo view --json owner,name,isFork,parent

Step 2: Identify Upstream and Fork Remotes

Determine the remote configuration:

# List all remotes with their URLs
git remote -v

# Check if this repo is a fork
IS_FORK=$(gh repo view --json isFork -q '.isFork')

# If it's a fork, get parent info
if [ "$IS_FORK" = "true" ]; then
  PARENT_OWNER=$(gh repo view --json parent -q '.parent.owner.login')
  PARENT_NAME=$(gh repo view --json parent -q '.parent.name')
fi

Remote Classification Logic:

Scenario	Upstream Remote	Push Remote
Single remote (origin)	origin	origin
Fork: origin=fork, upstream=parent	upstream	origin
Fork: origin=parent, fork remote exists	origin	fork remote
Multiple remotes, one is fork	non-fork remote	fork remote

Detection Algorithm:

# Get current user's GitHub username
CURRENT_USER=$(gh api user -q '.login')

# For each remote, check if it belongs to current user
for remote in $(git remote); do
  REMOTE_URL=$(git remote get-url $remote)
  # Extract owner from URL (handles both HTTPS and SSH)
  REMOTE_OWNER=$(echo "$REMOTE_URL" | sed -E 's/.*[:/]([^/]+)\/[^/]+\.git$/\1/' | sed 's/\.git$//')

  if [ "$REMOTE_OWNER" = "$CURRENT_USER" ]; then
    FORK_REMOTE=$remote
  else
    UPSTREAM_REMOTE=$remote
  fi
done

# Default fallback
UPSTREAM_REMOTE=${UPSTREAM_REMOTE:-origin}
FORK_REMOTE=${FORK_REMOTE:-origin}

Step 3: Create a Feature Branch and Commit Changes

Prepare the work for a PR before rebasing or pushing:

1. Inspect git status --short, staged changes, unstaged changes, and untracked file names.
2. If CURRENT_BRANCH is DEFAULT_BRANCH, main, or master, generate a concise branch name from the user's request and the changes. Follow repository naming conventions when present, avoid collisions with local and remote branches, create the branch, and update CURRENT_BRANCH.
3. If the working tree contains changes, stage the intended current work and commit it. Generate a concise commit message from the request and diff, and follow repository commit style, sign-off, and signing requirements.
4. Perform the branch creation and commit without asking the user to choose a branch name, switch branches, provide a commit message, or commit the changes themselves.

# Create a feature branch automatically when currently on the base branch.
if [ "$CURRENT_BRANCH" = "$DEFAULT_BRANCH" ] || \
   [ "$CURRENT_BRANCH" = "main" ] || \
   [ "$CURRENT_BRANCH" = "master" ]; then
  # Derive NEW_BRANCH from the request and diff, for example feat/add-export.
  # Add a short numeric suffix if the name already exists locally or remotely.
  git switch -c "$NEW_BRANCH"
  CURRENT_BRANCH=$NEW_BRANCH
fi

# Commit all intended current work when the tree is dirty.
if [ -n "$(git status --porcelain)" ]; then
  git status --short
  git diff
  git diff --cached
  git add -A
  git diff --cached
  # Derive COMMIT_MESSAGE from the request and staged diff. Add flags such as
  # -s or -S when required by repository instructions.
  git commit -m "$COMMIT_MESSAGE"
fi

Do not include editor artifacts, generated secrets, credentials, or unrelated files in the commit. If repository instructions require tests before committing, run them and include the result in the PR description.

Step 4: Sync and Rebase onto the Upstream Default Branch

# Fetch latest from upstream
git fetch "$UPSTREAM_REMOTE" "$DEFAULT_BRANCH"

# Rebase current branch onto latest default branch
git rebase "$UPSTREAM_REMOTE/$DEFAULT_BRANCH"

# If rebase fails, inform user
if [ $? -ne 0 ]; then
  echo "Rebase failed. Please resolve conflicts manually."
  git rebase --abort
  exit 1
fi

Step 5: Push Branch to Remote

Check if branch exists on remote and push:

# Check if branch exists on the push remote
REMOTE_BRANCH_EXISTS=$(git ls-remote --heads $FORK_REMOTE $CURRENT_BRANCH | wc -l)

if [ "$REMOTE_BRANCH_EXISTS" -eq 0 ]; then
  # Branch doesn't exist, push with upstream tracking
  git push -u $FORK_REMOTE $CURRENT_BRANCH
else
  # Branch exists, force push (after rebase) with lease for safety
  git push --force-with-lease $FORK_REMOTE $CURRENT_BRANCH
fi

Important: Always use --force-with-lease instead of --force for safety.

Step 6: Gather PR Content Information

# Get all commits between default branch and current branch
git log $UPSTREAM_REMOTE/$DEFAULT_BRANCH..HEAD --pretty=format:"%h %s%n%b" --no-merges

# Get the diff summary
git diff --stat $UPSTREAM_REMOTE/$DEFAULT_BRANCH..HEAD

# Get the full diff for analysis
git diff $UPSTREAM_REMOTE/$DEFAULT_BRANCH..HEAD

# Get list of changed files
git diff --name-only $UPSTREAM_REMOTE/$DEFAULT_BRANCH..HEAD

Step 7: Check for PR Template

# Check for PR template in common locations
PR_TEMPLATE=""
for template_path in \
  ".github/pull_request_template.md" \
  ".github/PULL_REQUEST_TEMPLATE.md" \
  "docs/pull_request_template.md" \
  "PULL_REQUEST_TEMPLATE.md"; do
  if [ -f "$template_path" ]; then
    PR_TEMPLATE="$template_path"
    break
  fi
done

# Also check for template directory
if [ -z "$PR_TEMPLATE" ] && [ -d ".github/PULL_REQUEST_TEMPLATE" ]; then
  # Use default template if exists
  if [ -f ".github/PULL_REQUEST_TEMPLATE/default.md" ]; then
    PR_TEMPLATE=".github/PULL_REQUEST_TEMPLATE/default.md"
  fi
fi

# Read template content if found
if [ -n "$PR_TEMPLATE" ]; then
  cat "$PR_TEMPLATE"
fi

Step 8: Generate PR Title and Description

Title Generation Rules:

1. If single commit: Use commit message subject line
2. If multiple commits: Summarize the overall change
3. Follow conventional commit format if project uses it: <type>(<scope>): <description>
4. Keep under 72 characters

Description Generation:

If PR template exists, fill in the template sections:

Common Template Section	How to Fill
## Summary / ## Description	Summarize changes from commits and diff
## Changes / ## What	List key changes from diff
## Why / ## Motivation	Extract from commit bodies or infer from changes
## Testing	List test files changed or suggest manual testing
## Screenshots	Leave placeholder if UI changes detected
## Checklist	Leave checkboxes for user to complete
Fixes # / Closes #	Extract issue references from commits

If no template, generate structured description:

## Summary

[2-3 sentences summarizing what this PR does]

## Changes

- [Key change 1]
- [Key change 2]
- [Key change 3]

## Testing

[How the changes were tested or should be tested]

---
[Any issue references found in commits]

Step 9: Create the Pull Request

# Determine the base repository for the PR
if [ "$IS_FORK" = "true" ]; then
  # For forks, create PR against parent repo
  BASE_REPO="$PARENT_OWNER/$PARENT_NAME"
  gh pr create \
    --repo "$BASE_REPO" \
    --base "$DEFAULT_BRANCH" \
    --head "$CURRENT_USER:$CURRENT_BRANCH" \
    --title "$PR_TITLE" \
    --body "$PR_BODY"
else
  # For non-forks, create PR in same repo
  gh pr create \
    --base "$DEFAULT_BRANCH" \
    --head "$CURRENT_BRANCH" \
    --title "$PR_TITLE" \
    --body "$PR_BODY"
fi

Use HEREDOC for body to preserve formatting:

gh pr create --title "$PR_TITLE" --body "$(cat <<'EOF'
## Summary

[Generated summary here]

## Changes

- Change 1
- Change 2

EOF
)"

Step 10: Report Results

After PR creation, provide:

# Get PR URL and details
gh pr view --json url,number,title,state

Output Format

---

PR Created Successfully

PR: #[NUMBER] - [TITLE] URL: [PR_URL] Base: [BASE_BRANCH] ← Head: [HEAD_BRANCH] Remote: Pushed to [FORK_REMOTE]

Summary

[Brief description of what the PR contains]

Files Changed

File	Changes

Next Steps

• Review the PR description and edit if needed
• Add reviewers if required
• Wait for CI checks to pass
• Address any review comments

---

Error Handling

Situation	Action
No commits ahead of base	"No changes to create PR. Your branch is up to date with [base]."
Branch name already exists	Generate another meaningful name with a short numeric suffix and continue.
Commit fails	Report the exact failure while preserving the user's working tree and staged changes.
Rebase conflicts	"Rebase failed due to conflicts. Please resolve manually and re-run."
Push rejected	"Push failed. Check if you have write access to the remote."
PR already exists	"A PR already exists for this branch: [URL]. Opening existing PR."
No remote access	"Cannot access remote. Check your authentication with gh auth status."
Fork detection failed	"Could not determine fork relationship. Please specify the target repo."

Advanced Options

Draft PR

gh pr create --draft --title "$PR_TITLE" --body "$PR_BODY"

Add Reviewers

gh pr create --reviewer "user1,user2" --title "$PR_TITLE" --body "$PR_BODY"

Add Labels

gh pr create --label "enhancement,needs-review" --title "$PR_TITLE" --body "$PR_BODY"

Link to Issue

If commits reference issues (e.g., "Fixes #123"), automatically add to PR body:

# Extract issue references from commits
ISSUES=$(git log $UPSTREAM_REMOTE/$DEFAULT_BRANCH..HEAD --pretty=format:"%B" | grep -oE "(Fixes|Closes|Resolves) #[0-9]+" | sort -u)

Important Notes

1. Safety First: Always use --force-with-lease instead of --force when pushing after rebase
2. Fork Awareness: Automatically detect and handle fork workflows
3. Template Respect: Always check for and use PR templates when available
4. Conventional Commits: If project uses conventional commits, follow the format
5. Issue Linking: Preserve issue references from commit messages
6. Review Before Submit: Show generated title/description for user approval before creating PR
7. No Branch or Commit Prompt: Automatically create a feature branch and commit current work; never ask the user to perform or confirm those operations
