Low-risk findings.
2 low severity findings. Worth noting, but not necessarily harmful.
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
The skill’s runtime path only ingests the `spec` passed into `JsonUIProvider`/`Renderer` (and optionally streamed from `createUIStream`), which is user-supplied JSON UI content rather than trusted first-party provider text.
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
The skill uses runtime API endpoints ("/api/generate-ui" and "/api/chat-ui") via createUIStream/createChatUI to fetch UI specs that are injected into the Renderer, so those endpoints can directly control the agent's rendered instructions/specs.
