Get all stocks in a given industry on a date.
AI agents call get_industry_members to retrieve information from A Share without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves a list of stocks belonging to a specified industry for a given date. It is a read-only operation that returns information without side effects, aligning with the 'Read' category definition of retrieving or querying data. The low severity reflects minimal risk from misuse—returning stock lists poses no blast radius for financial or operational harm.
From the tool's definition Tool name 'get_industry_members' and description 'Get all stocks in a given industry on a date' indicate pure data retrieval with no modification, deletion, or execution of external operations.

"default": "deny",
"tools": {
"get_industry_members": {}
}
