Game programming languages - C#, C++, GDScript. Learn syntax, patterns, and engine-specific idioms for professional game development.
Clone a game template from the gallery as a starting point. Use when the user says "use a template", "start from a template", "clone flappy-bird", "use the platformer template", or wants to quickly bootstrap a game from an existing example. Do NOT use for creating a game from scratch (use make-game).
Builds and refactors Phaser 3 browser games. Use for creating a new Phaser project, adding scenes, entities, physics, UI, tilemaps, animations, input, audio, camera, or for fixing Phaser-specific bugs and performance problems.
Use for Roblox Engine API lookup during implementation: finding the correct engine class or service, confirming properties, methods, events, callbacks, datatypes, enums, globals, and built-in libraries, and verifying parameter, return, and property usage for a known engine task. Prefer this skill when the problem is referential rather than architectural.
OpenGame is an open-source agentic framework for end-to-end web game creation from a single text prompt, using LLMs, Game Skill (Template + Debug), and headless browser evaluation.

Use when the agent is building or iterating on a web game (HTML/JS) and needs a reliable development + testing loop: implement small changes, run a Playwright-based test script with short input bursts and intentional pauses, inspect screenshots/text, and review console errors with render_game_to_text.

Generate engine-specific test helper libraries for the project's test suite. Reads existing test patterns and produces tests/helpers/ with assertion utilities, factory functions, and mock objects tailored to the project's systems. Reduces boilerplate in new test files.
