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: 0.90). This skill explicitly instructs the agent to use Membrane actions (e.g., "Get Messages" via `membrane action run` / the "Get Messages" entry in the Popular actions and the "Searching for actions" / "Running actions" sections of SKILL.md) to fetch user-generated messages from 1msg, which are untrusted third-party content that the agent would read and could influence subsequent actions.
