WHAT IT DOES

What create_lobby_manager does on Sbox

AI agents use create_lobby_manager to create or update resources in Sbox, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sbox environment.

RISK

Why create_lobby_manager is rated Medium

This tool generates/creates a script file within the s&box game engine. It writes code artifacts (lobby manager scripts) to the project, which is a reversible write operation. It does not execute code, delete data irreversibly, or involve financial transactions. The blast radius is medium since it creates game logic files that could affect multiplayer session management.
