Low

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

In `scripts/install_from_zip.rb`, the required runtime workflow downloads/extracts a remote `https://...zip` and then reads outsider-authored `SKILL.md` inside the extracted zip (including YAML frontmatter description) via `discover_and_install_skills` → `install_skill` → `extract_description` → `File.read(skill_file)`, so the agent ingests free text originating from the zip provided by the user/outsider.
