Daily English Speaking Practice

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Chinese-language English speaking practice coach with no code execution, data access, persistence, or hidden high-impact behavior.

Installers should expect a Chinese-language English conversation coach; review the broad trigger keywords if accidental activation for generic role-play or speaking-practice requests would be annoying.

Vague Triggers

Finding

The trigger list includes very generic phrases such as '练口语', '口语练习', and '角色扮演', which are common user intents and may cause this skill to activate for broad, unrelated requests. Overly broad routing can hijack user intent, reduce user control, and increase the chance that the wrong skill handles sensitive or important conversations.

Finding

The display name and description are entirely in Chinese, which may indicate the skill is presented in a fixed language/locale rather than offering the user a choice. There is no accompanying text in the manifest indicating that the language is optional, user-selectable, or intentionally limited to a Chinese-speaking audience.
