Rive CLI: Build Rive Files from Text with an AI Agent
Rive's new command-line tool lets an AI agent build a Rive file from text, with no editor open. What that means for a designer, and the bonus module it added to the Scripting Course.
Rive released the Rive CLI, a free technical preview. Until now an agent could build in Rive in two ways: the agent inside the editor, or your own agent driving the editor through MCP. Now there's a third: an agent writes the whole Rive file as text, builds it, checks its own pictures, and hands you a file that opens in the editor. No editor open while it works, and no you in the room either.
What Changed?
An agent can build a complete Rive scene on its own. I tested it from my phone: a 3D solar system with real planet textures, twenty minutes, and it opened in the editor first try. That's the scene in the video above.
What comes back is a finished thing. Regular content (shapes, text, timelines, state machines) arrives as editable Rive objects. Anything the agent drew with a script is a black box with inputs: you can bind and animate its knobs, but you can't grab a planet with the mouse. Decide which parts should stay editable before the agent starts.
What This Means for You
Taste didn't get automated. Correct came from the agent; feeling right came from me looking at a picture and saying "not like that". The job moves up a level: say what a thing should do, what it must never do, and check the picture. That's what the Scripting Course teaches, and the course is now updated with a bonus module on the Rive CLI and 3D: we build the sun from this experiment and push it into our own game as a script with one input.
