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
esm.sh is a widely used Deno CDN (low risk) but ghuc.cc is an untrusted third-party GitHub proxy that obscures origin and can serve arbitrary/updated TypeScript — making the ghuc.cc URL a suspicious download source.
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 documentation shows Deno URL imports that will be fetched and executed at runtime (e.g., https://esm.sh/package and https://ghuc.cc/worker-tools/html-rewriter/index.ts), making them runtime external code dependencies.
