CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 1.00). These URLs point to a personal domain that hosts a downloadable executable script (call.mjs) and the skill explicitly instructs users to curl and run it, which is a direct, unverified distribution vector commonly used to deliver malware.

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

• Potentially malicious external URL detected (high risk: 0.90). The skill/documentation instructs fetching and running remote executable code (call.mjs) via curl -sO https://fittings.sh/skill/call.mjs, which would download and then be executed (node call.mjs), so it is an external code fetch that can execute at runtime.

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 signed quote and the client signs an authorization with a private key to pay (example: export FITTINGS_PRIVATE_KEY and run call.mjs). It references spending USDC on Base, off-chain signing, and facilitator settlement — i.e., the client can perform/will authorize real payments when given a wallet key. This is a specific financial execution capability (crypto wallet signing/payments).
