A workflow for creating a new independently buildable game inside the repository’s games folder. It sets up the package, project settings, Vite development server, scenes, and runtime startup.

Use it when adding a Pixi-only, Three-only, or hybrid game project, or when copying the structure of an existing example game.

It gives a new game the expected repository structure and renderer setup so it can be built and run consistently.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00068	$0.01852
Opus 5.5	$0.00027	$0.00741
Sonnet 5.5	$0.00014	$0.00370
Haiku 4.5	$0.00007	$0.00185

Security

Grade A, and why

create-game scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create Game

Scaffold a new workspace package under games/<id>/. Do not invent a parallel projects/ tree. Do not copy node_modules, dist, or demo binary assets.

After the package exists, add Script components with .cursor/skills/create-game-component/SKILL.md. Gameplay systems that are not a new Script: .cursor/skills/implement-runtime-feature/SKILL.md. Runtime and renderer-dependency details: docs/runtime.md.

1. Name and renderer

Ask if missing. Then lock:

Field	Rule
Folder / `project.json` `name`	Same id: `games/<id>/`. Must match `PROJECT_ID_PATTERN`: `^[A-Za-z0-9._-]+$`
npm name	`@games/<id>`
Display name	Human title in `project.json` `displayName`
Vite port	Unique. Grep `games/*/vite.config.ts` (`port:`). Editor is 5173; project-server is 8787

Pick one renderer profile:

Profile	Copy structure from	`project.json` `renderers`	Scene `renderer`	Dependencies
Pixi-only	`games/solitaire`	`["pixi"]`	omit or `"pixi"`	`renderer-pixi` — no `renderer-three`
Three-only	`games/muonline-game` then drop Pixi / hybrid mount	`["three"]`	`"three"`	`renderer-three` — no `renderer-pixi`
Hybrid	`games/editor-features-demo` or `games/muonline-game` (`src/mount-renderers.ts`)	`["pixi", "three"]`	`"hybrid"` when both 2D and 3D nodes exist	both renderers

Games that never use 3D must not depend on Three. Games that never use 2D must not depend on Pixi.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
