MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (low risk: 0.10). The workflow fetches specification web pages and searches GitHub repositories for reference implementations, which can return arbitrary outsider-authored content.

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

• Potentially malicious external URL detected (medium risk: 0.30). The skill instructs fetching specification and security guidelines from ap2-protocol.org, which is an external domain supplying behavior-governing instructions, but lacks strong publisher provenance or cryptographic verification.

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

• Direct money access detected (high risk: 1.00). The skill documentation describes building an AP2 Credentials Provider agent which manages payment credentials, tokenization (DPAN), payment mandate validation, and facilitates secure payment between agents and payment processors. This constitutes specific financial operations infrastructure (handling payment credentials, tokenization, and facilitating payment transactions).
