What it does
When installed, the agent follows a structured process for making a small isometric action RPG game in web technology such as Three.js or React. It works in vertical slices: first a playable loop (menu, movement, one fight, a reward, progression), then adds systems only after each slice is tested and saves correctly. It also keeps game data separate from runtime state and suggests test fixtures for tricky states like boss phases or save migrations.
Great for
- Developers prototyping a browser-based isometric action RPG
- Teams that want a disciplined, testable vertical-slice workflow for game features
- Someone extending an existing Three.js or React game with combat, zones, or saves
Skip it if
- People without programming experience, since the output is code that must be run and maintained, not a finished game
- Non-web game engines such as Unity or Unreal, because the guidance targets Three.js/React-style stacks
- Projects where an agent should not modify the codebase without review, because it expects to edit files, run tests and builds
Try asking
- “Build a playable isometric ARPG prototype in Three.js with movement, one enemy, and a reward loop”
- “Add a second zone transition and save/load support to my existing isometric RPG in React”
- “Review my combat code for deterministic state and atomic inventory updates in my isometric game”

Ask for the task
No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.
Get better results
- Point the agent at your existing game entry point and tests first so it can inspect the baseline before changing anything.
- Ask for one vertical slice at a time rather than a full game, matching the skill's build order.
- Review the commands it runs (tests, lint, build) and any changes to save logic before accepting them.
