## Why This Matters for Agents

**For trading agents:** Know if a wallet is a whale, bot, or retail user before executing strategies.

**For security agents:** Detect suspicious patterns instantly without building custom heuristics.

**For research agents:** Get structured data instead of parsing raw blockchain JSON.

**For DeFi agents:** Understand who you're interacting with before approving transactions.

---

## Quick Start

**1. Install the skill:**
```bash
npx clawhub@latest install chain-sensei
```

**2. Use in your agent:**
Just ask naturally:
- "What's the risk of 0x1234...?"
- "Is this wallet safe to interact with?"
- "Who owns this token?"

**3. For premium features:**
Your agent will automatically handle x402 payment negotiation.
Make sure you have USDC on Base for payments.
