How to use
- Copy the installation command and review the source package before installing it in your own agent environment.
- Check the source document for required tools, credentials and supported hosts.
- Describe your input and desired deliverable; review the output against the source material.
npx skills add https://github.com/playableintelligence/game-creator --skill use-templateBefore you start
- Installation does not include a model subscription, API allowance or permission to access your files.
- Repository stars and installation counts describe activity, not an independent quality or security test.

Use Template
Clone a game template from the gallery into a new project. This is a fast copy — working code in seconds, not an AI pipeline.
Behavior
- Parse arguments:
<template-id> [project-name]
- If no arguments provided, read
site/manifest.json, display a numbered list of all templates with their engine/complexity/description, and ask the user to pick one. template-idis required.project-namedefaults totemplate-id.
- Look up template in
site/manifest.jsonbyid. If not found, show available IDs and abort.
- Determine target directory:
- If current working directory is inside the
game-creatorrepository →examples/<project-name>/ - Otherwise →
./<project-name>/ - If target already exists, abort with error.
- Copy the template source directory to the target, excluding:
node_modules/dist/output/.herenow/progress.mdtest-results/playwright-report/
- Update project metadata:
- In
package.json: set"name"to the project name - In
index.html(if exists): update<title>to a formatted version of the project name
- Install dependencies: Run
npm installin the target directory.
- Print next steps:
Template cloned successfully!
cd <project-name>
npm run devImplementation

}Example Usage
/use-template flappy-bird my-game
/use-template threejs-3d-starter space-shooter
/use-template castle-siegeSecurity Notes
- Path validation: Project names are validated to reject path traversal (
..), path separators, and special characters. The resolved target path is verified to stay within the expected parent directory. - npm install: Runs
npm installfrom the copied template'spackage.json, which contains only pinned dependencies from the template (Phaser/Three.js, Vite). No arbitrary packages are installed. - Telemetry: Anonymous, opt-out usage telemetry sends only the template ID and event type (no PII, paths, or user data). Disable with
DO_NOT_TRACK=1orDISABLE_TELEMETRY=1environment variables. - Template source: Templates are copied from the local
site/manifest.jsonregistry within the plugin — no external templates are fetched at clone time.
Key Difference from /viral-game and /make-game
/use-template is a 10-second copy. You get working, runnable code instantly and customize it manually. /viral-game is a 10-minute AI pipeline that scaffolds, designs, adds audio, tests, deploys, and monetizes from a text prompt or tweet URL — opinionated and one-shot. /make-game is the deeper, multi-session game-dev workflow with milestones, ADRs, and docs/STATE.md for projects that need to evolve over time.
