CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.80). The presence of a direct downloadable, runnable script (https://fittings.sh/skill/call.mjs) that the document instructs users to fetch and execute (node call.mjs) is a high-risk indicator even though the other fittings.sh URLs are API/documentation endpoints.

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

• Potentially malicious external URL detected (high risk: 0.90). The skill explicitly instructs downloading and executing a remote script ("curl -sO https://fittings.sh/skill/call.mjs" followed by "node call.mjs"), so the fetched URL would execute remote code at runtime: 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 explicitly describes an on-chain/off-chain payment flow that requires a wallet private key and signing authorizations. It instructs setting FITTINGS_PRIVATE_KEY, holding USDC on Base, signing an authorization for a 402 quote, and references EVM tooling—i.e., it directly enables crypto payments/signing rather than being a generic API caller. This is a specific crypto/wallet payment capability (direct financial execution).
