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 explicitly reads and acts on Slack messages (see the "Read recent messages" / "messages" actions in SKILL.md), which are user-generated, open third-party content that the agent is expected to interpret and can influence follow-up actions like replying, reacting, or pinning.
