WHAT IT DOES

What stocks__list_stock_themes does on AI 代理人任務中樞

AI agents call stocks__list_stock_themes to retrieve information from AI 代理人任務中樞 without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why stocks__list_stock_themes is rated Low

Even though stocks__list_stock_themes only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
