| description | GAME skill. Run Matt Shumer's aim prompt to build a game against a named reference (COD, Hades, Brotato, …) — fill three paragraphs, execute, fan-out + harsh critic + blind A/B until the human stops you. Pure prompt; no harness. Art: image gen for 2D/textures, Blender MCP for 3D meshes — both feed the game. Claude (/gauntlet-loop, /loop) and Codex ($gauntlet-loop, /goal). Use for Gauntlet Loop, aim prompt, one-prompt game build, COD-style loop. |

Gauntlet Loop
This is a game skill. Pure prompt. No functions.
On invoke you are building a game to the level of a named reference game.
Fill the three-paragraph aim prompt, then run it. Do not paste it for the
user. Do not build a capture suite, state machine, or scoring framework around
it. The prompt is the method.
- Read AGENTS.md — the prompt + game defaults + what not to invent.
- Read the harness overlay for loop verbs only:
- Infer nouns from
$ARGUMENTS / the message. Default domain = game. One question max if THING is missing.
- Fill → execute on the game → keep going until the human stops you.

Art for the game (not instead of the game)
| Need | Tool | Doc |
|---|
| Sprites, textures, UI pixels, concepts | Image gen | ASSETS.md |
| 2D hero/monsters (Brotato-like) | Image gen sprite factory (style lock → hero → batch → import) | ASSETS.md |
| Real meshes, GLB/FBX, 3D props/weapons | Blender MCP | BLENDER_MCP.md + ASSETS.md |
Critic grades in-game frames vs the real reference game. Art tools only close asset gaps — then wire into the playable build. For 2D sprite games, characters/monsters are image-gen sprites with one locked art language — not Blender, not procedural ovals.
Do not
- Treat this as a generic site/deck skill — games first
- Dump the prompt and stop — you run it
- Invent tools, harnesses, contracts, or round machinery
- Soften the critic / lower the reference / invent a stop condition
- End after one cycle and ask whether to continue
- Mix harness verbs (
/loop on Codex, /goal on Claude, ultracode on Codex)
- Lag the game out with capture farms / headless engine spam — the game stays playable
- Replace the game loop with endless image-gen or Blender-only rounds
