Game Creator - Setup Guide¶

Source: playableintelligence/game-creator via skills.sh - 31.8K combined installs across 31 indexed listings; first documented November 4, 2026 (morning sweep) GitHub: 355 stars, no LICENSE file (the README License section states MIT), last pushed 2026-11-03, 31 directories at skills//SKILL.md Category: Game production for agents: ideation, core loop design, level and systems tuning, art direction and playtest loops Quality Tier: 🟡 Yellow: game-3d-assets draws Socket and Snyk Warns, and the repo ships no LICENSE file even though the README states MIT

Game Creator is an opinionated Claude plugin that turns a prompt into a playable browser game on one of two engines: Phaser 3 for 2D and Three.js for 3D. Thirty-one skills divide the work between reference guidance (engine patterns, assets, audio, architecture), user-invocable commands (viral-game, make-game, improve-game, add-feature) and review passes.

The pipeline is the product. Every code-modifying step is followed by a QA subagent that runs build, headless runtime, gameplay, architecture and visual checks, with an autofix loop of up to three attempts. Games are scaffolded from one of two shipped templates rather than generated from scratch, and every game exposes window.render_game_to_text() so an agent can read state as JSON instead of interpreting pixels.

Installation¶

The README documents one install line, with an agent flag for scoping:

npx skills add playableintelligence/game-creator

npx skills add playableintelligence/game-creator -a claude-code

The same pattern works for other targets the README names:

npx skills add playableintelligence/game-creator -a codex

npx skills add playableintelligence/game-creator -a cursor

The README states the pack works with 40 or more coding agents through npx skills add. When it is installed as a plugin, the commands are namespaced, for example /game-creator:viral-game, /game-creator:make-game and /game-creator:add-assets.

The remaining 11 indexed listings range from 586 to 893 installs, covering monetization, promo recording, template cloning, world generation and multiplayer.

Why This Matters for Hermes Agents¶

Agent-built games usually fail in the same place: the code compiles, nothing throws, and the game is unplayable. Game Creator answers that with a QA subagent after every step and an autofix loop, so a Hermes agent gets a failing signal from a headless browser rather than from a human playing the result.

The second transferable idea is the fixed architecture. Every game, 2D or 3D, uses an EventBus for cross-module traffic, a single GameState with reset(), and a Constants file for every magic number. An agent that knows the layout can add a feature without re-reading the whole codebase, and the architecture validator can flag drift mechanically.

render_game_to_text() is the pattern worth stealing for non-game work too. It exposes current state as a JSON string, which gives an agent a readable observation channel for a canvas app that has no DOM to inspect.

The pack is also honest about scope boundaries. add-assets is 2D only, add-3d-assets is 3D only, review-game makes no changes, and quick-game deliberately skips deploy and monetization, so routing between skills stays predictable.

Two cautions belong in the same breath. The QA path assumes Node, Vite and Playwright are available, and monetization means calling third-party services: Play.fun registration needs its MCP server, and the 3D asset skills reach paid APIs.

Usage¶

You say	What happens
"make a space invaders game"	viral-game scaffolds from the Phaser template, adds pixel art, polish, audio, then deploys and monetizes
"/game-creator:viral-game 2d my-game"	One-shot pipeline: scaffold, sprites, design, audio, promo video, deploy to here.now and Play.fun
"build a game from this tweet"	fetch-tweet pulls the post through the fxtwitter API, then viral-game builds from it
"/game-creator:make-game"	Multi-session project: idea, scaffold, phases with milestones, ADRs and a state file
"add chiptune music and sound effects"	add-audio writes Strudel.cc music patterns and Web Audio SFX
"replace the shapes with pixel art"	add-assets generates sprites through renderPixelArt and the palette system
"review my game architecture"	review-game produces a read-only architecture and performance review
"add Playwright tests to my game"	qa-game writes gameplay, visual regression and accessibility tests

Verification¶

Fetch one raw skill file to confirm the tree still matches what skills.sh indexed. The path below is skills/quick-game/SKILL.md on branch main, and it returned 200 on November 4, 2026:

curl -fsSL https://raw.githubusercontent.com/playableintelligence/game-creator/main/skills/quick-game/SKILL.md | head -20

A response opening with name: quick-game and a description confirms the skill content is live. Then re-run the install for your agent and confirm the command set is registered:

npx skills add playableintelligence/game-creator -a claude-code

If the plugin form is what you installed, check that /game-creator:quick-game autocompletes in the agent before running the longer pipelines.

Integration with CorpusIQ¶

CorpusIQ is the connector layer that lets AI assistants read the systems a business already runs on - accounting, payments, CRM, email, files and analytics - and answer with the source named. It is read-only by design: it retrieves data and never writes to, or acts in, a connected system, which is what makes it safe to point at live accounts.

This page is part of the CorpusIQ directory, the reference we maintain for the MCP server and agent-skill ecosystem. Run alongside CorpusIQ, a third-party server like this one can be combined with a company's own business data in a single answer.

Limitations¶

Snapshot data, verified November 4, 2026: 31,774 combined installs across 31 indexed listings; 355 GitHub stars; no LICENSE file; last pushed 2026-11-03. Counts drift over time.
No LICENSE file exists at the repository root, while the README License section states MIT. Treat the terms as unresolved until the file lands.
The README warns that games using @strudel/web for audio must carry an AGPL-3.0-compatible licence, and the tech stack table lists Strudel.cc as AGPL-3.0.
game-3d-assets carries a Socket Warn and a Snyk Warn in the sampled set.
The pipeline assumes Node, Vite 7 and Playwright are installed locally; the QA subagent runs headless Chromium.
Monetization and 3D generation reach outside the repo: Play.fun registration needs its MCP server, worldlabs needs a WLT_API_KEY, and retrodiffusion is a paid API.

Pro Tips¶

Start with quick-game when you want to see whether the toolchain works on your machine. It skips assets, audio, deploy and monetization, so failures are easy to attribute.
Keep per-run cost down by using viral-game for a throwaway prototype and make-game for anything you intend to iterate on across sessions.
Read the architecture validator output before editing by hand. The EventBus, GameState and Constants rules are what make the later add-feature runs cheap.
Do the deploy step last and separately. game-deploy validates before and after publishing, which is easier to read when nothing else is running.
Pin your own copy if you depend on a specific template. The repo moves fast, and both templates are copied, not generated, so drift changes your scaffold.
