Security
2 findings: 1 critical severity, 1 medium severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
The installation procedure permits fetching and installing arbitrary user-supplied SKILL.md content and immediately writing/reloading it into the runtime while also enabling credential prompts, which together create strong vectors for remote code execution, credential exfiltration, and supply-chain/backdoor abuse.
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 prompt instructs the agent to fetch and install arbitrary SKILL.md content into the runtime (writing to ~/.gini and POSTing to a local API), which modifies the agent's filesystem and runtime state and can enable execution of untrusted code even without sudo.
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
The required runtime workflow ingests outsider-authored SKILL.md content by accepting user-pasted text or reading/fetching a user-supplied URL/file path (fetch with `curl -fsSL <url>` or `read the file`) into `bun run gini skill validate` and subsequent risk review that reads the skill body and sidecars.
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 install procedure explicitly runs `curl -fsSL <url>` to fetch a user-supplied SKILL.md at runtime (SKILL.md:17), so the fetched remote content (<url>) can directly control the installed skill's prompts/instructions.
