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
The GitHub links point to a third‑party/individual account (Cluka-399) rather than an established vendor — an unvetted repo used as a download/install source can be a vector for malicious code.
