Search for exercises by name. Returns matching exercise IDs and names.
AI agents call search_exercises to retrieve information from MusclesWorked without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves exercise data (IDs and names) based on search input. It performs a read-only lookup against the 856-exercise dataset with no capability to modify, delete, or execute actions. No financial or destructive operations are possible. The blast radius of misuse is minimal—an agent could retrieve irrelevant exercise data but cannot cause harm.
From the tool's definition Tool name 'search_exercises' and description 'Search for exercises by name. Returns matching exercise IDs and names.' indicate a query-only operation with no side effects.
