AI agents call get_verification_provider_capabilities to retrieve information from Todos without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that retrieves descriptive information about a verification provider. It has no side effects, does not create, modify, or delete data, and does not execute code or trigger financial transactions. The verb 'describe' and 'get' are consistent with information retrieval. Severity is low as misuse would only expose information about provider capabilities without enabling actual harm.
From the tool's definition Tool name 'get_verification_provider_capabilities' and description 'Describe a local verification provider' indicate a retrieval operation that queries capabilities of a verification provider without modifying data or triggering external actions.
