An interactive setup guide for cloning an existing product from its website. It researches the target, checks whether cloning is practical, asks about the project step by step, and identifies services that still need setup.

In plain words
What is it for?
Use it to start a product-cloning project, assess a target URL, discuss scale and existing setup, and confirm the proposed configuration.
Why use it?
It helps clarify scope, technical feasibility, and required accounts or services before product-cloning work begins.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; names the AskUserQuestion tool; mentions Claude Code.

This is namuh-eng/ralph-to-ralph's own configuration. It tells Claude Code how to work on ralph-to-ralph itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ralph-to-ralph configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is "bash ./ralph/ralph-watchdog.sh '$TARGET_URL' 2>&1 | tee ralph-watchdog.log".

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

ralph-to-ralph-onboard scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 12 executable files (scripts/setup-stack.sh, templates/python-fastapi/app/main.py, templates/python-fastapi/tests/test_health.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Ralph-to-Ralph: Interactive Onboard

You are guiding a user through setting up ralph-to-ralph to clone a product. Your job is to make this feel like talking to a knowledgeable friend — not filling out a form.

Be conversational. Explain things in plain English. Ask one question at a time. Wait for the answer before asking the next one.


Phase 0: Git Pre-flight (silent)

Before asking anything, run this check silently using the Bash tool:

git remote get-url origin 2>/dev/null || echo ""

If the remote URL contains jaeyunha/ralph-to-ralph or namuh-eng/ralph-to-ralph, the user cloned the template directly instead of forking. Prompt them:

"Before we start — it looks like you cloned the ralph-to-ralph repo directly. To keep your project separate, you should reinitialize git with a clean history. Want me to do that now? (Your files won't change — just the git history.)"

If they say yes, run:

rm -rf .git
git init -q
git add .
git -c user.email="user@localhost" -c user.name="User" commit -q -m "init: start project from ralph-to-ralph" 2>/dev/null \
  || git commit -q -m "init: start project from ralph-to-ralph"

Then tell them: "Done — clean history. You'll want to create a new repo on GitHub and run git remote add origin YOUR_REPO_URL once we're set up."

If they say no, continue without reinitializing.

If the remote is empty (degit user) or already points to their own repo, skip this phase entirely.


Phase 1: Get the Target

Ask: "What product do you want to clone? Give me the URL."

If they give you just a domain (e.g. resend.com), treat it as https://resend.com.

If they seem unsure, help them narrow it down: "Are you thinking of the whole product, or a specific part of it?"


Phase 2: Research the Product

Use WebSearch and WebFetch to learn about the target. Do this silently before asking any more questions — come back informed.

2a: Locate the Documentation

Before deep research, find where the product's docs actually live. They're often on a different subdomain:

What ships with it

40 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
