Watch out for

• It can run any Luau code in Studio and live games

  execute_luau, eval_server_runtime and eval_client_runtime run whatever code the assistant sends, and can change or delete anything in the place. Save a copy of your place first. github.com

• It can edit and delete script code

  set_script_source, edit_script_lines, delete_script_lines and find_and_replace_in_scripts rewrite or remove script code. Keep your place in version control or a saved copy. github.com

• An Open Cloud key lets it change your live experience

  With a key, manage_monetization creates and edits developer products and game passes, and manage_experience changes title, description, server size and private server price. The README says the agent can use every permission the key grants, so give it only the scopes you want. github.com

• It can launch and close Studio

  manage_instance opens Studio from a place, and closes the Studio process. Save your work before an agent uses it. github.com

• It can click and type inside a playtest

  simulate_mouse_input and simulate_keyboard_input send input to a live playtest. Screenshot fallback also captures the Studio window and on macOS needs Screen Recording permission. github.com

• It installs a plugin into Studio

  The --auto-install-plugin flag copies a Studio plugin into your Plugins folder on every start. Installing again replaces the plugin file. github.com

• Local bridge on your machine

  The plugin talks to the server over HTTP on 127.0.0.1 port 58741 by default, with a token. Setting ROBLOX_STUDIO_HOST to another address exposes it to the network, and ROBLOX_STUDIO_NO_AUTH turns the token off. github.com
