AI agents call get_role_on_matter to retrieve information from Smokeball without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about a role assigned to a matter in the Smokeball practice management system. It performs a query/lookup operation without modifying, deleting, or executing any actions. The blast radius of misuse is minimal—an agent could retrieve unwanted information but cannot alter data, perform financial operations, or trigger external effects.
From the tool's definition Tool name 'get_role_on_matter' and description 'Get a specific role on a matter' indicate a retrieval operation with no side effects. The verb 'get' is a standard read operation.
