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
canvas-design ingests the outsider-authored end-user free-text request directly in the required “DESIGN PHILOSOPHY CREATION” and “DEDUCING THE SUBTLE REFERENCE” steps to generate the manifesto/philosophy and then visually express it, without any requirement to select from a predefined safe item list.
