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 list includes direct installer scripts (install.sh and install.ps1) served from a non-standard host — direct-download scripts are high-risk distribution vectors for malware, while the remaining links are documentation or known schemas and are low risk.
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 includes installer commands that fetch and immediately execute remote scripts (powershell "irm https://chatgpt.com/codex/install.ps1 | iex" and shell "curl -fsSL https://chatgpt.com/codex/install.sh | sh"), which are runtime external dependencies that execute remote code.
