Cn Case Converter

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small, disclosed text case-conversion utility with no evidence of hidden access, persistence, or unsafe behavior.

Before installing, confirm you are comfortable with Chinese-only documentation and the publisher's promotional links. Security-wise, the included script appears limited to local text case conversion.
