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's SKILL.md shows it connects to the external 1s2u.com API via the Membrane proxy and explicitly states that connection objects may include clientAction.agentInstructions (and uiUrl) which the agent is expected to read and act on, so third-party content from the remote app can drive agent behavior.
