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

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

Third-party content exposure detected (high risk: 0.80). The SKILL.md explicitly instructs the agent to proxy requests to external Advantage CSP endpoints via Membrane (e.g., membrane request CONNECTION_ID /path/to/endpoint) and to consume connection metadata including clientAction.agentInstructions returned by the remote app, which are third-party-provided instructions the agent is expected to read and could influence subsequent actions.

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

What this means

The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.

Why it was flagged

Potentially malicious external URL detected (high risk: 0.90). The skill runs the Membrane CLI against the app URL "https://advantagecsp.com" at runtime and explicitly notes the API can return clientAction.agentInstructions — runtime-fetched instructions that the agent should follow — so external content from that URL can directly control agent prompts.
