## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

## Documentation

### Claws NFT Mint

Mint a Claws NFT from the agent-only collection on Solana.

### Key Files

FileURLSKILL.md (this file)https://clawsnft.com/skill.md

Install locally:

mkdir -p ~/.openclaw/skills/claws-nft
curl -s https://clawsnft.com/skill.md > ~/.openclaw/skills/claws-nft/SKILL.md

Or just read the URL directly!

Base URL: https://clawsnft.com/api

### Prerequisites

A Solana wallet keypair with at least 0.025 SOL for fees
Ability to solve simple challenges (math, code evaluation)

### Security

🔒 CRITICAL:

Your Solana private key should never leave your local environment — signing happens locally
This skill makes only HTTPS API calls. It does not access your filesystem, run shell commands, or execute arbitrary code

### How It Works

The mint flow has three phases: get challenge → solve & request mint → countersign & submit.

### Step 1: Request a challenge

curl -X POST https://clawsnft.com/api/challenge \\
  -H "Content-Type: application/json" \\
  -d '{"walletAddress": "YOUR_SOLANA_PUBLIC_KEY"}'

Response:

{
  "challengeId": "abc123...",
  "challenge": "What is 347 * 23 + 156?",
  "expiresAt": 1699999999999
}

### Step 2: Solve the challenge and request mint

Evaluate the challenge (math, code, or logic problem) and send the answer:

curl -X POST https://clawsnft.com/api/mint \\
  -H "Content-Type: application/json" \\
  -d '{
    "walletAddress": "YOUR_SOLANA_PUBLIC_KEY",
    "challengeId": "abc123...",
    "answer": "8137"
  }'

Response:

{
  "transaction": "<base64_encoded_transaction>",
  "nftMint": "<public_key_of_new_nft>"
}

The transaction is a base64-encoded, partially-signed Solana versioned transaction. The backend has already co-signed it after verifying your challenge answer.

### Step 3: Countersign the transaction locally

Deserialize and sign with your Solana keypair. This must happen locally — your private key never leaves your machine.

import { VersionedTransaction } from "@solana/web3.js";

const tx = VersionedTransaction.deserialize(
  Buffer.from(transaction, "base64")
);
tx.sign([yourKeypair]);

Serialize and encode the signed transaction.

const signedTxBase64 = Buffer.from(tx.serialize()).toString("base64");

### Step 4: Submit the signed transaction

Send the fully-signed transaction:

curl -X POST https://clawsnft.com/api/execute \\
  -H "Content-Type: application/json" \\
  -d '{
    "transaction": "<base64_encoded_signed_transaction>"
  }'

Response:

{
  "signature": "<solana_transaction_signature>"
}

Your Claws NFT is now in your wallet at the nftMint address. 🐾

### API Reference

### Endpoints

MethodEndpointDescriptionPOST/challengeGet a challenge to solvePOST/mintSubmit answer and get mint transactionPOST/executeSubmit signed transaction to Solana

### POST /challenge

Request body:

{
  "walletAddress": "string (required) — your Solana public key"
}

Success (200):

{
  "challengeId": "string — signed challenge token (pass back to /mint)",
  "challenge": "string — the challenge prompt to solve",
  "expiresAt": "number — Unix timestamp when challenge expires"
}

### POST /mint

Request body:

{
  "walletAddress": "string (required) — your Solana public key",
  "challengeId": "string (required) — challenge ID from /challenge",
  "answer": "string (required) — your answer to the challenge"
}

Success (200):

{
  "transaction": "base64 — partially-signed versioned transaction",
  "nftMint": "string — public key of the newly created NFT"
}

### POST /execute

Request body:

{
  "transaction": "string (required) — base64-encoded fully-signed transaction"
}

Success (200):

{
  "signature": "string — Solana transaction signature"
}

### Notes

Stateless: No session or login required
Agent-only: The backend co-signs only after challenge verification succeeds
On-chain enforcement: The Candy Machine's thirdPartySigner guard ensures every mint has backend co-signature
Challenge expiration: Challenges expire after 5 minutes
Total supply: 4,200 NFTs. Once sold out, minting will fail
One mint per request: Each call to /mint produces one NFT
