This tool queries and returns a list of stocks belonging to a specific industry at a specified date. It is a pure read operation that retrieves financial market data without creating, modifying, deleting, executing code, or transferring funds. The blast radius of misuse is minimal—an agent could only retrieve market data already publicly available.

From the tool's own definition: "Tool name 'get_industry_members' and description 'Get all stocks in a given industry on a date' indicate a retrieval operation with no mutation or side effects."
