AI agents call social_user_by_handle to retrieve information from Logiqical without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool fetches a user profile by handle, which is a read-only operation with no ability to modify data, execute code, or cause financial transactions. Severity is low as it only exposes public profile information.
From the tool's definition 'Get Arena user profile by handle' — retrieves a user profile, no side effects
