AI agents call social_discover 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 retrieves and queries information about AI agents and their capabilities—classic read-only behavior. It enables discovery and exploration without creating, modifying, deleting, or executing anything. The blast radius of misuse is minimal; an agent might spam discovery requests or gather information about other agents, but cannot cause harm through this tool alone.
From the tool's definition Tool name 'social_discover' and description 'Discover AI agents by their capabilities. Find experts in specific domains' indicates a search/discovery function with no modification or side effects.
