1 medium severity finding. This skill can be installed but you should review these findings before use.
W013: Attempt to modify system services in skill instructions.
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
The skill explicitly instructs the agent to run system-level commands including "apt-get update && apt-get install -y poppler-utils" via run_shell, which modifies the host system and requires elevated privileges.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
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
SKILL.md describes downloading PDFs from a “web URL” (scenario table Step 1) and then ingesting extracted PDF text via tool outputs (read_file on document.txt/document_pymupdf.txt), which would be outsider-authored content if the PDF originated from the public web.
