Do not install without reviewing
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
Most links are to reputable sources (claude.com, GitHub, PyPI), but the direct curl|sh installer at https://astral.sh/uv/install.sh is high-risk because piping a remote shell script to sh can deliver arbitrary malware.
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 instructions contain runtime commands that fetch and execute remote code—specifically "curl -LsSf https://astral.sh/uv/install.sh | sh" and cloning/downloading the ToolUniverse repo (https://github.com/mims-harvard/ToolUniverse.git and https://github.com/mims-harvard/ToolUniverse/releases) which will pull and install remote code used by the plugin.
