game-development

game-development is a cursor rule for Cursor from MN-Lizard-Team/aiyu-multi-agent. It costs 15 tokens per session (1,158 once invoked), scanned A, original, Apache-2.0.

A guide that organizes game-development work and directs it to specialized approaches for web, mobile, PC, or VR/AR games, as well as 2D and 3D projects.

In plain words
What is it for?
It is for planning game projects involving platforms, 2D or 3D graphics, game design, multiplayer features, or game art.
Why use it?
It helps developers choose suitable methods for the target platform, game dimension, and specialty area instead of treating every game project alike.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

game-development 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 4d 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.

Game Development

Orchestrator skill that provides core principles and routes to specialized sub-skills.


When to Use This Skill

You are working on a game development project. This skill teaches the PRINCIPLES of game development and directs you to the right sub-skill based on context.


Sub-Skill Routing

Platform Selection

If the game targets... Use Sub-Skill
Web browsers (HTML5, WebGL) game-development/web-games
Mobile (iOS, Android) game-development/mobile-games
PC (Steam, Desktop) game-development/pc-games
VR/AR headsets game-development/vr-ar

Dimension Selection

If the game is... Use Sub-Skill
2D (sprites, tilemaps) game-development/2d-games
3D (meshes, shaders) game-development/3d-games

Specialty Areas

If you need... Use Sub-Skill
GDD, balancing, player psychology game-development/game-design
Multiplayer, networking game-development/multiplayer
Visual style, asset pipeline, animation game-development/game-art
Sound design, music, adaptive audio game-development/game-audio

Core Principles (All Platforms)

1. The Game Loop

Every game, regardless of platform, follows this pattern:

INPUT  → Read player actions
UPDATE → Process game logic (fixed timestep)
RENDER → Draw the frame (interpolated)

Fixed Timestep Rule:

  • Physics/logic: Fixed rate (e.g., 50Hz)
  • Rendering: As fast as possible
  • Interpolate between states for smooth visuals

2. Pattern Selection Matrix

Pattern Use When Example
State Machine 3-5 discrete states Player: Idle→Walk→Jump
Object Pooling Frequent spawn/destroy Bullets, particles
Observer/Events Cross-system communication Health→UI updates
ECS Thousands of similar entities RTS units, particles
Command Undo, replay, networking Input recording
Behavior Tree Complex AI decisions Enemy AI

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.
