Security audit

balltalk

Security checks across malware telemetry and agentic risk

Overview

This is a basketball advice skill with static markdown instructions and a banner image; I found no hidden directives, executables, credential access, or persistence.

Safe to install as a basketball-focused helper. Use it for public basketball questions; avoid sharing private fantasy league details or personal information if you do not want those details included in web searches.
