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: 0.75). The skill’s runtime workflow includes “Search authoritative sources” and “Generate correction report” using web/package registry lookups; those fetched pages/registry entries are outsider-authored free text that can be ingested into the LLM context for comparison and reporting.
W021: Hidden or invisible Unicode characters detected (potential obfuscation or prompt injection)
Why it was flagged
