AI agents call get_stock_industry to retrieve information from Ashare without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves industry classification information from a financial database. It is a read-only query operation with no side effects, no code execution, no data modification, and no financial transactions. The worst case misuse would be unauthorized data access, which has minimal blast radius in a financial data context where such information is typically public.
