1 critical severity finding. 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
These instructions download Windows .exe binaries directly from a third-party site (frippery.org) instead of the official BusyBox site; direct executables from unverified/third‑party hosts are a high-risk distribution vector for malware.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
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 instructs the user at runtime to download and then run BusyBox executables from https://frippery.org/files/busybox/busybox.exe (and the other frippery.org busybox binaries listed), which fetches and executes remote code required for the skill.
