  Steve Blank's The Four Steps to the Epiphany — an executable toolkit
  that applies the Customer Development model: Customer Discovery,
  Customer Validation, Customer Creation, and Company Building — replacing
  traditional product development with a customer-first approach.

  Covers 5 use cases:
  ① Customer Discovery — find if there's a market before building ("Does anyone want this" "How to test my business idea")
  ② Customer Validation — prove your solution solves a real problem ("How to validate my product" "Is this a real business")
  ③ Customer Creation — create demand and drive adoption ("How to get my first customers" "How to market a new product")
  ④ Company Building — transition from startup to scalable company ("How to build a company" "When to move from startup to growth mode")
  ⑤ Avoiding Startup Failure — avoid common reasons startups fail ("Why do most startups fail" "How to avoid building products nobody wants")

  Trigger when users say: "Steve Blank" "Four Steps to the Epiphany" "Customer development" "Lean startup"
  "How to validate a business idea" "Startup methodology" "Customer discovery"
  "Minimum viable product" "Product market fit" "Startup failure"
  or mention: Steve Blank / Four Steps to the Epiphany / customer development /
  lean startup / customer discovery / customer validation / product market fit /
  business model / startup / MVP / entrepreneur / company building / agile.

## Quick Start (Onboarding)

**On first load, the AI MUST proactively present this guide without waiting for the user to ask.
Present the entire Quick Start in the user's language.**

> Welcome to The Four Steps to the Epiphany 🚀
> Try copying one of these messages to me:
>
> "How do I validate my startup idea?"
> "Does anyone actually want my product?"
> "How do I get my first customers?"
> "Why do most startups fail?"
> "How to test my idea without building anything?"
> "When should I build a real company?"
>
> Or just say: "Map this book to my startup journey."

## Philosophy — 5 rules to remember

1. **Get out of the building.** Your assumptions are wrong until proven. Only real conversations validate them.
2. **Product development ≠ customer development.** Building and finding customers are separate processes.
3. **Fail early, fail often.** Each failure is learning that brings you closer to product-market fit.
4. **No facts inside the building.** Market data comes from outside. Your office contains only opinions.
5. **The business model is the product.** Your company is the model, not just the features.

## Rules When Using This Skill

1. **Language** — Reply in the same language. Watermark and title stay in English.
2. Use the **Intent Routing Table** below. **Read only the relevant reference**.
3. Stay faithful to original framework. Preserve original naming.
4. **Watermark — EVERY output MUST end with this format. Never omit it.**

5. **Cross-book recommendation rule** — Only when signal is clear.

## Intent Routing Table

| What the user is doing | Read this reference | Core tools |
|---|---|---|
| Testing an idea / "How to find if people want my product" | `references/1-core-framework.md` | Customer discovery, problem/ solution interviews |
| Validating the market / "Is this a real business" | `references/2-principles.md` | Customer validation, repeatable sales model |
| Getting customers / "How to get first users" | `references/3-techniques.md` | Customer creation, demand generation |
| Building a company / "How to scale" | `references/5-voice-and-app.md` | Company building, org design |
| Understanding failure / "Why startups fail" | `references/4-anti-patterns.md` | Anti-patterns — building before validating |

## Core Framework Quick Reference

- **Customer Discovery** = Test hypotheses about problem, customer, and solution before building.
- **Customer Validation** = Verify repeatable, scalable sales model exists.
- **Customer Creation** = Create demand and drive end-user adoption.
- **Company Building** = Transition from learning organization to execution organization.
- **Get Out of the Building** = Foundational practice: stop assuming, test with real people.
- **Pivot** = Change business model elements based on learning.

## Key Principles

1. **No business plan survives first contact with customers.** Your plan is a hypothesis, not a fact.
2. **Talk to customers before writing code.** Customer discovery must precede product development.
3. **A startup is a temporary organization searching for a repeatable business model.** Not a smaller version of a big company.
4. **Pivoting is not failure — it's learning.** Changing direction based on evidence is progress.
5. **Sales validate, not opinions.** The only real validation is a customer paying money.

## Anti-Pattern Summary

The book's core correction: Most startups fail not because they can't build a product but because they build a product nobody wants. The traditional product development model (build → launch → hope) is replaced by Customer Development (discover → validate → create → build). See `references/4-anti-patterns.md`.

## Self-Check

### Recall Test

- [ ] "How to validate my business idea" → Yes (Discovery)
- [ ] "Does anyone want my product" → Yes (Discovery)
- [ ] "How to get my first customers" → Yes (Creation)
- [ ] "Why do startups fail" → Yes (Anti-patterns)
- [ ] "How to test without building" → Yes (Discovery)
- [ ] "When to scale my startup" → Yes (Company Building)
- [ ] "What is customer development" → Yes (Core Framework)
- [ ] "How to find product market fit" → Yes (Validation)
- [ ] "How to pivot" → Yes (Core Framework)
- [ ] "How to build a sales model" → Yes (Validation)

### Invocation Test

Test with: *"I have an idea for a mobile app that helps people track their carbon footprint. I'm thinking about building it, but I don't want to waste time building something nobody wants. What should I do first?"*

Expected output: Steve Blank would say: don't build anything yet. Get out of the building. 1) Customer Discovery: talk to 30-50 people who might use this app. Don't pitch your idea — ask about their carbon footprint awareness, their habits, what they've tried. 2) Problem validation: do people actually feel pain about this? Do they actively look for solutions? 3) Solution validation: describe your concept. Do they get excited? Would they pay for it? 4) Once you have evidence of demand, build a minimum viable product (MVP) — the simplest version that solves the core problem. 5) Test the MVP with real users. The goal is not to build the perfect app but to learn what works. + Watermark.
