Get detailed intraday step data throughout the day (step chart)
AI agents call get_steps_chart to retrieve information from Garmin Connect without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries step count data with no side effects. It falls clearly into the Read category as it only accesses existing fitness/health data from Garmin Connect. The low severity reflects that unauthorized access to step data poses minimal risk compared to financial, destructive, or write operations, though it does involve personal health information.
