name	create-pr-github
description	Create and (optionally) merge a GitHub pull request using wrapper scripts (preferred) or GitHub CLI (fallback), following the repo policy for rebase and merge.

Create PR (GitHub)

Purpose

Create a GitHub pull request in a consistent, policy-compliant way, and include the repo's preferred merge method guidance (rebase and merge).

Priority order:

1. FIRST: Use scripts/pr-github.sh wrapper script (designed for permanent approval)
2. SECOND: Use GitHub MCP tools (if available and wrapper doesn't fit)
3. LAST: Use gh CLI as final fallback

Hard Rules

Must

• Work on a non-main branch
• Ensure the working tree is clean before creating a PR
• Push the branch to origin before creating the PR
• Before creating the PR, post the exact Title and Description in chat
• Use the standard PR body template (Problem / Change / Verification)
• Use Rebase and merge for merging PRs to maintain a linear history (see CONTRIBUTING.md)

Must Not

• Create PRs from main
• Use "Squash and merge" or "Create a merge commit"
• Use --fill or any heuristic that guesses title/body (not supported by the wrapper)

Actions

0. Title + Description (Required)

Before running any PR creation command, provide in chat:

• PR title (exact)
• PR description (exact), using this template:

## Problem
<why is this change needed?>

## Change
<what changed?>

## Verification
<how was it validated?>

1. Pre-flight Checks

git branch --show-current
scripts/git-status.sh --short

2. Push the Branch

git push -u origin HEAD

3. Create the PR

Preferred: Wrapper Script

Create a PR:

echo "## Summary\n\nPR description" | scripts/pr-github.sh create --title "<type(scope): summary>" --body-from-stdin

Create and merge (only when explicitly requested):

echo "## Summary\n\nPR description" | scripts/pr-github.sh create-and-merge --title "<type(scope): summary>" --body-from-stdin

Fallback: gh CLI (if wrapper unavailable)

echo "## Summary\n\nPR description" | PAGER=cat gh pr create \
  --base main \
  --head "$(git branch --show-current)" \
  --title "<type(scope): summary>" \
  --body-file -

4. Merge (Only When Explicitly Requested)

This repository requires rebase and merge.

Preferred: Wrapper Script

scripts/pr-github.sh merge <pr-number>

Or combined create-and-merge:

echo "## Summary\n\nPR description" | scripts/pr-github.sh create-and-merge --title "<type(scope): summary>" --body-from-stdin

Fallback: gh CLI (if wrapper unavailable)

PAGER=cat gh pr merge <pr-number> --rebase --delete-branch

5. If Rebase-Merge Is Blocked (Conflicts)

git pull --rebase origin main
# resolve conflicts

git push --force-with-lease

Then retry the merge.

Why Prefer the Wrapper Script?

• Designed for permanent approval in VS Code (reduces friction)
• Enforces repo policies (rebase and merge, standard templates)
• Handles edge cases consistently
• Provides clear error messages
• Can be easily reproduced by Maintainers

Note on GitHub MCP Tools

GitHub MCP tools may be available for PR creation in the future, but currently the wrapper script is the most reliable approach. If GitHub MCP tools add PR creation support, they would become the preferred option (with wrapper as fallback).
