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: 0.80). The skill's SKILL.md and references/api-security.md explicitly instruct executing external API calls and scripts (e.g., ~/.claude/scripts/secure-api.sh facebook list-campaigns, curl to https://api.yourservice.com/items) and use dynamic context injection (!`command`) which causes the agent to fetch and ingest third-party responses that the workflow then interprets and acts on.
