Gauntlet 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.

1. Read [AGENTS.md](AGENTS.md) — the prompt + game defaults + what not to invent.
2. Read the harness overlay for loop verbs only:

• Claude Code → [CLAUDE.md](CLAUDE.md) (/loop, ultracode)
• Codex → [CODEX.md](CODEX.md) (/goal)

1. Infer nouns from $ARGUMENTS / the message. Default domain = game. One question max if THING is missing.
2. 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](ASSETS.md) | | 2D hero/monsters (Brotato-like) | Image gen sprite factory (style lock → hero → batch → import) | [ASSETS.md](ASSETS.md) | | Real meshes, GLB/FBX, 3D props/weapons | Blender MCP | [BLENDERMCP.md](BLENDERMCP.md) + [ASSETS.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
