3 findings — 1 critical severity, 2 medium severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E005: Suspicious download URL detected in skill instructions
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
Suspicious download URL detected (high risk: 1.00). They include direct links to Windows executables hosted on a third‑party domain (frippery.org) rather than an official, vetted package repository—direct .exe downloads from unverified sites are a high malware risk.
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
Third-party content exposure detected (high risk: 0.80). The skill's SKILL.md explicitly instructs downloading a BusyBox binary from a public site (Invoke-WebRequest to https://frippery.org/files/... in step 3), which causes the agent/user to fetch and execute untrusted third-party content that can materially change tool behavior.
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
Potentially malicious external URL detected (high risk: 0.90). The skill instructs at runtime to download and run a BusyBox executable from https://frippery.org/files/busybox/busybox.exe (and variants busybox64.exe, busybox64u.exe, busybox64a.exe), which fetches and executes remote code that the skill relies upon.
