Overview

This skill is a disclosed integration for managing a user's MJZJ supply-demand posts through MJZJ's API, with no hidden code or persistence found.

Install only if you intend to let the agent use your MJZJ API key to view and manage your MJZJ supply-demand posts. Review publish, refresh, and delete requests before approving them because those actions affect your account content.

• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally

Natural-Language Policy Violations

Low

• Category: Not specified by scanner
• Confidence: 90% confidence

Finding

The markdown states that returned business error information is usually Chinese text and can be surfaced directly to the user. This implies the skill may present Chinese-language responses regardless of the user's preferred language, which is a locale/language policy concern when no opt-in or alternative is provided.
