AI agents call get-activity-details to retrieve information from Strava without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves activity metadata and details from the Strava API without creating, modifying, deleting, or executing any operations. It is a read-only query that has minimal security blast radius even if misused by an AI agent, since it only accesses data the authenticated user already has permission to view.
