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). The skill accepts untrusted webhook POSTs at public endpoints (e.g., https://panda.tail7af24.ts.net/webhooks/{provider}) and the notify functions explicitly build agent prompts from event.data and call gateway.notify (see references/new-provider-checklist.md "build-prompt" / "notify-gateway"), so third-party payloads can directly influence agent behavior.
