CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.90). The SKILL instructs you to curl and run a remote script (call.mjs) from fittings.sh — downloading and executing scripts from an unvetted domain is a high-risk vector for malware or credential/theft (especially since the script is used to manage signing/payment keys).

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

• Potentially malicious external URL detected (high risk: 0.80). The skill documentation explicitly instructs downloading and running the remote script https://fittings.sh/skill/call.mjs (SKILL.md:49) and call.mjs itself references that URL, which means fetching and executing remote code is required for operation.

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

• Direct money access detected (high risk: 1.00). The skill explicitly describes a metered paid API and shows client-side payment flow that signs an authorization with a private key (FITTINGS_PRIVATE_KEY) and uses USDC on Base. It provides commands and examples that perform payment (node call.mjs with a wallet), warns about storing keys in plaintext, and references EVM/npm tooling (@x402/evm). This is a specific crypto wallet/payment integration enabling the agent/client to spend funds to settle calls, so it grants direct financial execution capability.
