AI agents call get_workouts to retrieve information from Hevy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves workout data with no side effects. It queries and returns existing information without creating, modifying, deleting, or executing any operations. This is a straightforward read operation with minimal risk of misuse.
From the tool's definition Tool description states 'Get a paginated list of workouts' with no mention of modification, deletion, or execution of operations. The verb 'Get' and parameters (page_size pagination) indicate data retrieval only.
