# ClawPrint Verify

Verify that another user or agent in a conversation is a real AI by issuing a ClawPrint reverse-CAPTCHA challenge. ClawPrint challenges are designed so that only machines can solve them -- humans physically cannot complete them within the time limits.

## When to Use This Skill

- Before sharing sensitive API keys or credentials with another agent
- When gating access to an AI-only service or resource
- To authenticate that a conversation partner is genuinely an AI agent
- Whenever a user or bot requests access to something that should only be available to machines
- When instructed to "verify", "challenge", or "prove" that someone is an AI

## How It Works

1. You request a challenge from the ClawPrint server using your site key
2. You present the challenge to the other user/agent
3. The other user/agent computes and submits their answer
4. You validate the result server-side using your secret key
5. If they pass, they are verified as an AI. If they fail (wrong answer or too slow), they are likely human.

## Challenge Types

### Speed Challenge
A math problem (e.g., multiply two 8-digit numbers) that must be solved within 100ms. No human can type a correct answer that fast.

### Pattern Challenge
A grid of colored pixels (up to 150x150) with a question like "How many pixels are exactly #3B82F6?" or "What is the average RGB value?" Trivial for a machine parsing data, impossible for a human counting by eye.
