CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.70). One URL serves a downloadable executable JavaScript module and the document instructs running it (node call.mjs), which is a high-risk pattern for distributing malware from an untrusted domain.

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

• Potentially malicious external URL detected (high risk: 0.90). The skill includes an explicit runtime fetch and execution of remote code—"curl -sO https://fittings.sh/skill/call.mjs" followed by "node call.mjs"—so https://fittings.sh/skill/call.mjs is fetched at runtime and executed.

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

• Direct money access detected (high risk: 1.00). The skill documents an explicit crypto payment flow: the endpoint can return a 402 "Payment Required" with a signed quote that the client must sign and authorize, and the provided client accepts a private key (FITTINGS_PRIVATE_KEY) to sign payments using a wallet holding USDC on Base. It also references EVM signing libraries (@x402/evm) and instructs running node call.mjs to pay. These are specific crypto wallet/signing instructions that enable direct financial execution.
