AI agents call immich_activities_statistics to retrieve information from Immich without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves statistical metadata (comment counts) about existing assets and albums. It performs a query operation with read-only semantics, no state changes, and minimal blast radius if misused by an AI agent. Classification as Read is appropriate.
