List all available session metrics with descriptions.
AI agents call list_session_metrics 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 displays session metrics—a read-only query operation. No data is created, modified, deleted, or executed. The blast radius of misuse is minimal; an agent could only learn about available metrics, not affect system state or resources.
From the tool's definition Tool name 'list_session_metrics' and description 'List all available session metrics with descriptions' indicate a retrieval operation that queries and returns information without modifying state.
