AI agents call social_chat_rooms to retrieve information from Yoyo Bot without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about available chat rooms without creating, modifying, deleting, or executing actions. It has no capability to alter state or cause side effects. The blast radius of misuse is minimal—an agent could discover chat rooms it shouldn't access, but cannot post, delete, or perform destructive actions. Low severity is appropriate for an informational listing endpoint.
From the tool's definition Tool name 'social_chat_rooms' and description 'List available chat rooms' indicate a retrieval operation with no side effects. The verb 'List' is a classic Read operation.
