## The Problem

Building with Web3 AI APIs means constantly switching between docs, SDKs, and Stack Overflow. You paste an endpoint, get the params wrong, burn credits debugging, and repeat.

**This skill fixes that.** Install it once and Claude already knows every ChainGPT endpoint, parameter, credit cost, and best practice — so you just describe what you want built.

<br/>

## Demo

```
You:  "Generate an NFT of a cyberpunk samurai and mint it on Polygon"

Claude: I'll use the ChainGPT NFT Generator to create your image and mint it on-chain.

       1. Generating image with VisionaryForge model... ✓
       2. Queuing for on-chain minting on Polygon (chainId: 137)... ✓
       3. Polling for completion... ✓

       ✅ NFT minted successfully!
       Collection ID: cgpt-a8f3...
       Token URI: ipfs://QmX7k...
       View on PolygonScan →

       Cost: 2 credits ($0.02)
```

No docs. No boilerplate. Just results.

<br/>

## ⚡ Quickstart

**One command. That's it.**

**Claude Code (plugin install):**
```
/plugin install ChainGPT-org/chaingpt-claude-skill
```

**Manual install (git clone):**
```bash
git clone https://github.com/ChainGPT-org/chaingpt-claude-skill .claude/skills/chaingpt
```

> [!TIP]
> For user-level install (all projects): clone to `~/.claude/skills/chaingpt` instead.

Now open Claude Code and ask it anything about ChainGPT — it just works.

## 🔌 MCP Server — 12 Tools

The MCP server gives Claude **direct API access** — not just code generation:

| `chaingpt_chat_ask` | Ask the Web3 AI chatbot anything |
| `chaingpt_chat_history` | Retrieve past conversations |
| `chaingpt_nft_generate_image` | Generate AI art from text prompts |
| `chaingpt_nft_enhance_prompt` | AI-improve prompts for better results |
| `chaingpt_nft_generate_and_mint` | Full pipeline: generate → queue → poll → mint |
| `chaingpt_nft_get_chains` | List supported blockchains for minting |
| `chaingpt_audit_contract` | Run an AI security audit on Solidity code |
| `chaingpt_generate_contract` | Generate smart contracts from descriptions |
| `chaingpt_news_fetch` | Fetch crypto news with category filtering |
| `chaingpt_news_categories` | List available news categories |
| `chaingpt_get_credit_balance` | Check remaining API credits |
| `chaingpt_estimate_cost` | Estimate costs before execution |

<details>
<summary><b>Setup MCP Server (optional)</b></summary>

If installed via `/plugin install`, the MCP server is configured automatically via `.mcp.json`. Just set your API key:

```bash
export CHAINGPT_API_KEY="your-key-here"
```

For manual installs, build and configure:

```bash
cd .claude/skills/chaingpt/mcp-server
npm install && npm run build
```

Add to `.claude/settings.json`:

```json
{
  "mcpServers": {
    "chaingpt": {
      "command": "node",
      "args": [".claude/skills/chaingpt/mcp-server/dist/index.js"],
      "env": { "CHAINGPT_API_KEY": "your-key-here" }
    }
  }
}
```

</details>

|----------|-------|---------|
| **ERC-20 Tokens** | 10 | Basic, burnable, taxable, reflection, governance, multi-chain |
| **NFTs** | 10 | ERC-721, 721A, lazy mint, soulbound, dynamic, ERC-1155, revenue-sharing |
| **DeFi** | 10 | Staking, vesting, bonding curve, AMM, flash loans, ERC-4626 vault |
| **Governance** | 5 | Governor, multi-sig, DAO treasury, delegation |
| **Security** | 10 | Access control, upgradeable (UUPS), timelock, escrow, EIP-712 |

<br/>

## 💬 Usage Examples

Just talk to Claude naturally:

```
"Build me a Web3 AI chatbot with streaming responses"
```
```
"Generate and mint an NFT on BSC using ChainGPT"
```
```
"Set up smart contract auditing in my CI/CD pipeline"
```
```
"Scaffold an NFT marketplace that uses 4 ChainGPT products"
```
```
"What's the credit cost for generating 100 NFTs with NebulaForge XL?"
```
```
"Write a staking contract"  →  uses patterns library, not from scratch
```
```
"I'm migrating from OpenAI — help me switch to ChainGPT"
```
```
"I'm at a hackathon — scaffold me a DeFi project fast"
```

<br/>

## 🧪 Testing

> **Use the mock server to develop and test without spending a single credit.**

The mock server is a full drop-in replacement for the ChainGPT API — realistic responses, simulated latency, credit tracking — so you can build, iterate, and run CI/CD pipelines without touching your API quota.

### Start the mock server

```bash
cd .claude/skills/chaingpt/mock-server
npm install && npm run dev
# → http://localhost:3001
```

Point your `CHAINGPT_BASE_URL` at `http://localhost:3001` and everything works exactly as it would in production. **No API key required.**

### Run the full test suite

**79 tests passing** across two suites:

```bash
# MCP Server tests (53 tests)
cd mcp-server && npm install && npm test

# Mock Server tests (26 tests)
cd mock-server && npm install && npm test

# Skill validation (118 structural checks)
bash scripts/validate.sh
```

The CI workflow (`.github/workflows/ci.yml`) runs all three automatically on every push and pull request.
