name	mern-teardown
description	Tear down a MERN project — delete local files and optionally delete the GitHub repo.
argument-hint	[--delete-repo]
allowed-tools	Bash, Read, Glob, Grep

Purpose

Completely tear down a MERN project created by /mern-kit. Deletes all local files. By default, keeps the GitHub repo for reference — use --delete-repo to remove it too.

Arguments

• --delete-repo — Also delete the GitHub repository (default: keep it)

Prerequisites

• Must be run from inside the project directory (or provide the path)
• gh CLI authenticated (if --delete-repo)

Teardown steps

1. Detect project

Confirm this is a MERN project by checking for:

• turbo.json
• apps/web/
• packages/shared/

If any are missing, warn and ask the user to confirm before proceeding.

Record the project root (absolute path) for later deletion.

2. Detect GitHub remote

git remote get-url origin 2>/dev/null

• If a remote exists, extract owner/repo from the URL
• If no remote, skip GitHub steps

3. Show summary and confirm

Display exactly what will happen:

Project: /path/to/my-app
GitHub:  owner/repo (will be DELETED | will be KEPT)

This will permanently delete:
  - All local files in /path/to/my-app
  [- GitHub repository owner/repo (if --delete-repo)]

Type the project name to confirm: _

Do NOT proceed without explicit confirmation.

4. Delete GitHub repo (if --delete-repo)

gh repo delete owner/repo --yes

If this fails (permissions, network), stop and report — do not continue to local deletion so the user can retry.

5. Delete local project

cd ..
rm -rf /absolute/path/to/project

Use the absolute path recorded in step 1. Never use relative paths.

6. Confirm completion

Report what was deleted:

• Local directory: deleted
• GitHub repo: deleted / kept (with URL if kept)

Safety

• Always confirm before destructive operations
• Show the full absolute path that will be deleted
• Never delete parent directories or anything outside the project root
• If GitHub deletion fails, stop — don't leave the user with a deleted local copy and a still-existing repo they can't find
