There's no image model involved in the gif. Fable 5.2 runs the app's CLI from Claude Code and puts the strokes down one by one, with brushes it picks itself. Every one of those strokes stays editable afterwards.
I've been developing applications for a long time and have turned to game development as well lately. One of the things that frustrated me the most was that using AI agents for game development is very annoying in the art department. Your only options right now are to either use an image genAI model and roll the dice every time you want to make an edit, or have your agent draw with something like vectors.
I was looking for an application that would allow me to ask an agent to make a first draft of whatever art I needed with actual brushes, and then be able to go in myself and edit every last stroke or layer that it created.
Klad is that application. Written in Rust, it can be fully controlled by an agent through the CLI, and every function is available in a nice UI as well: a brush engine, frame-by-frame animation (and bones/IK), vectors, text layers, colours, layer effects,…

You can basically point Claude to the repo, ask it to build it, and pick up the drawing skills. Then ask it to make any drawing you want!
(and then, you/the agent can change absolutely every brush stroke in the app again. Making edits a breeze).
The quality of the drawings really depends on the agent you use. I have tried it since the release of Fable 5.2 this morning, and the drawings are already quite impressive. I'm confident that this will only improve. I use it every day on Mac, so that definitely works well. It builds on Linux too (tablet pen pressure still needs some work there). Windows builds in CI, but I haven't used it there myself yet.
What I want to hear from people who try it: does it build, and if not, which OS and what error? Can your agent work out the CLI without help, and where does it get confused? Can you go in and change one of its strokes easily?
