## What it does

The skill applies Andrew Chen’s The Cold Start Problem framework to products whose value depends on other users. It helps choose an atomic network instead of a broad market, identify the hard side, define the magic moment, and sequence launches network by network.

It scores launch and growth plans from 0 to 10, then lists the changes needed to reach 10/10. The framework separates acquisition, engagement, and economic effects, while its metrics focus on density and liquidity inside each sub-network rather than total registrations.

That makes aggregate growth numbers worth checking against cities, teams, or categories. In Claude Code, installation creates `~/.claude/skills/cold-start-problem/SKILL.md` after the install command is run.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add wondelai/skills --skill cold-start-problem -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/cold-start-problem/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/cold-start-problem/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add wondelai/skills --skill cold-start-problem -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/cold-start-problem/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add wondelai/skills --skill cold-start-problem -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/cold-start-problem/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install wondelai/skills cold-start-problem
```

2. **Manually: put the files in place**
- File: `.github/skills/cold-start-problem/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add wondelai/skills --skill cold-start-problem -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/wondelai/skills --path cold-start-problem
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/cold-start-problem/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add wondelai/skills --skill cold-start-problem -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/wondelai/skills/tree/HEAD/cold-start-problem/SKILL.md

## When to use it
- choose the first atomic network to launch
- solve the hard side of a marketplace
- define the product’s magic moment
- score a launch plan from 0 to 10
- separate network health by city, team, or category

## Example prompts
- Score our marketplace launch plan from 0 to 10 and list the changes needed for 10/10.
- Help me choose an atomic network and define the magic moment for this product.
- Our users are joining, but categories remain empty. Identify the hard side and sequence the network launches.

# The Cold Start Problem

A framework for starting and scaling products that live or die by network effects — marketplaces, social apps, messaging, and collaboration tools — distilled from Andrew Chen's *The Cold Start Problem*. Use it to launch products that are worthless until other users show up, to sequence growth network by network, and to navigate the five stages: the cold start, the tipping point, escape velocity, hitting the ceiling, and the moat.

## Core Principle

**Network effects start as a liability, not an asset.** Value lives in connections between users, and on day one there are none — the same force that makes a dense network unstoppable makes an empty one useless. You don't escape by launching to a market; you escape by building one tiny, complete, self-sustaining network at a time, solving its hard side first, then tipping adjacent networks with a repeatable playbook until the market follows.

## Scoring

**Goal: 10/10.** Rate launch plans and growth strategies for networked products 0-10 against the principles below. Report the current score and the specific changes needed to reach 10/10.

- **9-10:** Named atomic network with an instrumented magic moment, hard side solved first, repeatable tipping playbook, density/liquidity metrics, explicit ceiling and moat plan
- **7-8:** Clear atomic network and hard-side focus, but tipping tactics are ad hoc or metrics still track totals over density
- **5-6:** Network effects acknowledged, but the launch targets a broad market and both sides are treated equally
- **3-4:** Generic user-acquisition plan; network thinking limited to "add invites and hope it spreads"
- **0-2:** Big-bang launch to everyone at once, vanity signups, no hard-side strategy, no liquidity measures
