Security checks for vulnerabilities and agentic risk

Overview

This is a Chinese-language Amazon seller operations helper that asks for relevant Amazon seller tools, with no hidden code or persistence found.

Vague Triggers

Medium

Confidence
93% confidence
Finding

The description includes broad search-trigger phrases like '亚马逊怎么运营' and similar queries without clear boundaries on when the skill should activate. This can cause the agent to invoke the skill for loosely related requests, increasing the chance of over-broad tool use against commerce APIs and unintended processing of seller data or actions.
