The prompt

Original user prompt

In a folder oyu are going to create claled goat-simulator Build a browser-based 3D sandbox game heavily inspired by the original Goat Simulator.
The goal is NOT to make a normal animal simulator. The fun should come from chaotic physics, stupid interactions, breaking things, ragdolling, launching across the map, licking objects, causing chain reactions, and discovering ridiculous ways to destroy the environment.

Recovery status

Verbatim prompt recovered from the original Claude Code transcript. The same transcript directly records `claude-opus-5` with `xhigh` effort. The file published on the game page is the untouched output from this run; later improvement work happened in a separate project fork.

Provenance note. This is the untouched single-file output from the supplied opus-5/goat-simulator benchmark run. A later conversation explored improvements in a separate fork, but the original file here remained unchanged; the xhigh effort and claude-opus-5 model are directly recorded in the creation transcript.
