Get summary statistics of session metrics.
AI agents call get_metrics_summary to retrieve information from Session Buddy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns summary statistics—a read-only operation with no capability to modify, delete, or execute operations. It presents no blast radius for accidental misuse by an AI agent, as reading metrics poses minimal security risk.
