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's Editing workflow explicitly ingests arbitrary user-provided .pptx files ("When an existing .pptx file is provided..." in SKILL.md) and requires running scripts that extract and parse slide text/brand tokens (e.g., scripts/extract_brand.py and the markitdown calls in Section 1.2/1.3), and those extracted contents are used to drive triage, editing, and slide-generation decisions—so untrusted third-party file content can materially influence the agent's actions.
