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: 0.70). The skill explicitly fetches and ingests content from public third-party sources (e.g., linkedin:organizations:resolve accepts arbitrary LinkedIn URLs and the CLI calls Typefully API endpoints like /social-sets/.../drafts, /analytics/... and /queue which return user-generated/public social media content), as shown in SKILL.md and scripts/typefully.js, and those responses are used to build drafts, mentions, quote_post_url behavior, analytics-driven queries, and publishing decisions—so untrusted third-party content can materially influence tool behavior.
