CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 1.00). The document instructs downloading and executing a JavaScript module (call.mjs) from an untrusted/small domain—running fetched scripts can execute arbitrary code and is a common malware vector; the other URLs are API endpoints and not direct executables.

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.90). The skill instructs fetching and running remote JavaScript (curl -sO https://fittings.sh/skill/call.mjs then node call.mjs), which downloads and executes code at runtime from https://fittings.sh/skill/call.mjs.

MEDIUM W009: Direct money access capability detected (payment gateways, crypto, banking).

• Direct money access detected (high risk: 1.00). The skill includes an explicit crypto payment flow: the endpoint returns a 402 with a signed quote, the client must sign an authorization using a private key (FITTINGS_PRIVATE_KEY), and it expects a wallet holding USDC on Base. It even references EVM-related client libraries (@x402/evm) for signing. These are specific crypto signing/payment instructions (wallet, private key, signing), which constitute direct financial execution capability.
