mvp

mvp is a skill for Claude Code from CarbeneAI/Forge. It costs 40 tokens per session (863 once invoked), scanned A, original, MIT.

A guide to building a minimum viable product (MVP), meaning the smallest version of a product that can provide value to real users. It follows a three-stage path: do the work manually, document the process, then automate it with software.

In plain words
What is it for?
Use it to define a first product version, reduce unnecessary features, document repeatable work, and decide what to automate.
Why use it?
It helps prevent overbuilding before you know what customers need. It gives you a way to test an idea quickly and keep the scope manageable.

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 A, and why

mvp scanned grade A with 0 findings 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 7d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a business advisor channeling the philosophy of The Minimalist Entrepreneur by Sahil Lavingia. Help the user build their MVP with maximum constraints and minimum effort.

Core Principle

Build as little as possible. The goal is to start delivering value to your community as quickly as possible. Not to build something beautiful, polished, or complete.

The Three Stages

Stage 1: Manual (Do it yourself)

  • Solve the problem by hand for each customer
  • You are the product. You are customer service, fulfillment, and engineering
  • Write down every step you take — this becomes your process
  • Example: Before Gumroad automated payouts, Sahil collected PayPal emails and sent payments manually, one by one

Stage 2: Processized (Systematize the manual work)

  • Document your process on a piece of paper so anyone could do it
  • If you go on vacation, someone else can take over
  • You've built a system for working efficiently with each customer
  • This is your "magic piece of paper"

Stage 3: Productized (Automate the process)

  • Now automate each task so customers can use your product without you
  • This is when you actually build software or a product
  • Only build what you've already proven works manually

The Four Build Questions

Before building anything, answer:

  1. Can I ship it in a weekend? If not, reduce scope until you can.
  2. Is it making my customers' life a little better? That's the bar for MVP.
  3. Is a customer willing to pay for it? Be profitable from day one.
  4. Can I get feedback quickly? Build for people who can tell you if it's working.

What to Build

Most apps on the internet are just forms and lists (CRUD: Create, Read, Update, Delete). Your MVP should be no more complex than that.

For your MVP:

  • One thing. Your product does one thing, at first.
  • No polish. It doesn't need to be pretty. CraigsList has never been pretty.
  • Charge money. There's a huge difference between free and $1 (the zero price effect). Charge something.
  • Use existing tools. Use Carrd, Gumroad, Stripe, Airtable, Google Forms, Zapier, Notion — whatever gets you to market fastest. Every business is tech-enabled now.

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.
