CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.80). The SKILL instructs downloading and executing an unverified Node.js module (https://fittings.sh/skill/call.mjs) and placing a plaintext private key in the environment, which is a high-risk pattern for arbitrary code execution and credential theft.

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

• Potentially malicious external URL detected (high risk: 0.90). The skill explicitly instructs fetching and executing a remote script at runtime (curl -sO https://fittings.sh/skill/call.mjs followed by node call.mjs), meaning remote code from that URL would be executed on the agent/runtime.

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

• Direct money access detected (high risk: 1.00). The skill documentation includes explicit crypto payment and signing mechanics: the endpoint returns a 402 with a signed quote requiring the caller to sign an authorization, it instructs supplying a private key via FITTINGS_PRIVATE_KEY, references holding USDC on Base, and points to EVM-related client libraries (@x402/evm). Those are specific crypto/payment capabilities (wallets and signing) that enable financial execution rather than being merely generic tooling.
