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
This skill contains detailed guidance on privileged, state-changing operations (kernel driver loading, hypervisor EPT hooks, IOMMU domain reprogramming, toggling PCI Bus Master Enable, etc.) that would modify the host machine and require elevated/sudo privileges, so it risks compromising the machine state.
Low
Low-risk findings.
2 low severity findings. 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:858-910 instructs runtime fetching of external public web content (raw GitHub README/archive/description URLs), which will be ingested as free text into the agent’s LLM context, creating an indirect prompt-injection exposure path.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The skill explicitly instructs the agent to fetch and use remote raw GitHub files (e.g., https://raw.githubusercontent.com/gmh5225/awesome-game-security/refs/heads/main/README.md) at runtime to retrieve content that will be referenced in responses, meaning external content is fetched and injected into the agent’s prompt/context.
