Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Chinese-language helper for creating local text adventure MUD games, with no evidence of hidden access, network use, credential handling, or unsafe installation behavior.

Install this if you want a Chinese-language MUD/text-adventure creation helper. Be aware that the documentation and generated examples are Chinese-first, and any save-game feature you add may create a local savegame.json file in the game directory.

Confidence

Finding

This markdown file uses a single forced language throughout and does not indicate that users may select another language or that the content is intentionally limited to a Chinese-speaking audience. Under the language/locale policy check, this can be treated as a natural-language policy issue because the file imposes a locale-specific presentation without opt-in.
