Critical

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 URL https://x.ai/cli/install.sh is a direct .sh installer (curl|bash) — a high-risk delivery pattern that can distribute malware; the GitHub clone and docs links are standard/benign references in the skill text.

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 command "git clone https://github.com/user/repo.git" is executed at runtime (SKILL.md:185) and Grok auto-reads repository files like CLAUDE.md, .claude/, and AGENTS.md (SKILL.md:36-38), so cloning an external repo can inject remote files that directly control the agent's instructions and behavior.
