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 | $0.00034 | $0.00926 |
| Sonnet 5 | $0.00014 | $0.00370 |
| Haiku 4.5 | $0.00007 | $0.00185 |
Grade A, and why
create-game scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create Game
Scaffold a new workspace package under games/<id>/. Do not invent a parallel projects/ tree. Do not copy node_modules, dist, or demo binary assets.
After the package exists, add Script components with .cursor/skills/create-game-component/SKILL.md. Gameplay systems that are not a new Script: .cursor/skills/implement-runtime-feature/SKILL.md. Runtime and renderer-dependency details: docs/runtime.md.
1. Name and renderer
Ask if missing. Then lock:
| Field | Rule |
|---|---|
Folder / project.json name |
Same id: games/<id>/. Must match PROJECT_ID_PATTERN: ^[A-Za-z0-9._-]+$ |
| 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.

create-game is a skill published in the GitHub repository andvolodko/html5-game-editor (6 stars, last pushed 11d ago), licensed MIT. It adds 68 tokens to every session and 1,852 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
self-evolve
Capture reusable patterns from a finished project and lift them into framework-level priors (contracts, modules, skeletons) that future projects inherit. Run only when the user explicitly requests self-evolution; the orchestrator executes the workflow.
artist-self-evolve
Distill stable art-generation patterns from a completed project, so future projects produce comparable assets without re-discovering the prompts. Lead-dispatched only — orchestrator invokes this skill from its self-evolve flow with a game-slug message; do not self-trigger.
vibegame-build
Run VibeGame's standard end-to-end game development workflow with reviewer gates. Use when the user wants to create a game from zero or evolve an existing game across multiple stages.
vibegame-start
Resume a VibeGame orchestrator session after vibegame start. Use at the beginning of a Claude or Codex session to inspect team runtime state, repair missing persistent members, load goal and GDD context, inspect tasks, and ask the user what to do next.
design-npc
Use when the user wants to design an enemy, NPC, boss, companion, civilian, or wave-spawned mob's behavior. Walks perception, personality knobs, intent layer, action state machine, telegraphs, defeat handling, and group emergence — outputs a state-machine GDScript stub plus the recommended node tree. Trigger on…
headless-scripting
Use when a Summer project needs an operation no MCP tool exposes, such as baking a navmesh, generating collision shapes, authoring an Animation, building a TileSet, re-importing assets after file changes, or preparing a supported local export. Runs a GDScript file against Summer Engine from the shell. Also use when a…
