Samples
Games and demos built by an agent driving swallowtail, with source you can clone and run.
Each sample here was built by an agent driving swallowtail against a live editor: scenes assembled, scripts written, and the result proven by playing it. The source is public, so a claim on this page can be checked against the code.
Reversi
A complete Reversi game for Godot 4.7: boot, splash, intro, title, setup, match, pause, settings, how to play, credits and result, wired through one Stage autoload. Thirty GDScript files and eleven scenes. There are no sprites; the board, discs, buttons, sliders and transitions are drawn in _draw() from polygons and text against a 2560 by 1440 design box, so nothing goes soft at another resolution. The rules live in one RefCounted with no engine dependency past Vector2i, and the opponent plays at three depths, the deepest an alpha-beta search under a 60 ms budget.
The README records the brief it was built from, the tool’s own limits met along the way, and the asset licences.
The web export, deployed from the sample’s own repository.
Clone it, open it in Godot 4.7, and run it. MIT licensed.
Demos
Smaller builds that each prove one idea. They live in the main repository under samples/, ready to open with godot --path .:
A stylized water surface with a lighthouse and a free-flying camera.
A stylized grass field with controllable wind and a free-flying camera.
A five-minute getting-started film, edited as Godot scenes and rendered by the movie writer, beside the lighthouse coast it drives through the terminal, a playtest, an agent, and MCP.
Build your own
Every sample follows the loop the docs teach: discover the API, drive the editor, and prove it by playing. Start from the Quickstart.
