Quodlin works on a project you already have. It needs the Unity Editor installed to check that the code it writes actually builds — ideally the same version your project was made with.
Choose the folder your game lives in — the one with an Assets folder inside it. Quodlin reads the project and tells you anything worth fixing before you start.
Quodlin uses Claude to do the work, so it needs a key from console.anthropic.com. It's stored on your machine and never sent anywhere else.
Describe it the way you'd describe it to a friend — "add a campfire the player can light" — or pick one of the suggestions. It'll tell you which systems your game doesn't have yet.
Every change is snapshotted with git before it happens. The History tab undoes the last one completely.
After writing code it compiles your project in Unity and fixes its own errors before telling you it's done.
If it can't compile — wrong Unity version, project already open — it says so rather than claiming success.
Something broken or confusing? That's the most useful thing you can send back. Back to quodlin
