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 includes multiple explicit sudo package-install commands and an instruction ("Any tool not installed → install it") that directs the agent to install missing system tools, which would modify the host system state and may require 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
Yes—required runtime flow “Art of a specific thing (cat, rocket, dragon) → ascii.co.uk via curl + parsing” fetches outsider-authored public web HTML/text and then reads/extracts it into the agent’s LLM-relevant prompt context; similarly the “Fun ASCII Utilities via curl” endpoints (e.g., wttr.in) are fetched at runtime as free-form text.
