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 explicitly reads remote calendar feeds provided via ICS_URLS (see SKILL.md) and the code in scripts/read_ics.py (normalize_calendar_url + fetch_ics_url_content and the main loop) fetches and parses .ics content and treats the parsed JSON as "source of truth" for downstream use, so untrusted/public calendar data could supply content that influences agent decisions.
