Why it matters
Zenity describes testing skills in isolated environments with the services and task prompts needed to exercise different paths. Reading the entry file can miss downloaded instructions and package-install side effects. The method combines agent traces with process, filesystem and network observations, and distinguishes suspicious access from legitimate diagnostic behavior. A single run cannot establish complete path coverage or prove a skill harmless.
My takeaway: Evaluate untrusted skills in disposable environments with synthetic credentials and controlled egress. Follow fetched dependencies, record versions and network destinations, and inspect child processes and persistence changes. Test multiple task paths and enforce least privilege regardless of whether the model or static scanner raises an alert.
