Q: How do I install game-development?

Run npx skills add https://github.com/sickn33/agentic-awesome-skills --skill game-development in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/game-development/ (personal) or .claude/skills/game-development/ (project).

Game development orchestrator. Routes by platform, dimension, and engine fit (web 2D/3D, hybrid DOM+canvas, narrative tools). Use when starting or structuring a game project, choosing frameworks, or picking among Phaser, PixiJS, Kaplay, Canvas/WebGL, Three.js, Babylon.js, Godot, Unity, or Ink/Twine.

Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/sickn33/agentic-awesome-skills --skill game-development

01
Install
Run the command in your project. The CLI asks which agents to install for.
02
Describe the task
Ask your agent for something this skill covers. It loads game-development automatically when relevant.
03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

Game Development

Orchestrator skill — principles plus routing to specialized sub-skills.

When to Use This Skill

You are working on a game development project. This skill teaches PRINCIPLES 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, WebGPU)	`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`

Architecture / tooling

If you need...	Use Sub-Skill
Engine / framework choice, shell vs guest, fit tiers	`game-development/engine-selection`
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

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

Fixed-timestep starting point (not required for every game):

Physics/logic: Fixed rate (e.g., 50Hz)
Rendering: Synchronize with the display/frame scheduler and chosen power budget
Interpolate where appropriate; cap accumulated lag/substeps after pauses to avoid a catch-up spiral

Hybrid / UI-heavy games: the outer app may be DOM/event-driven; use a classic game loop only in canvas/WebGL viewports (or wherever simulation ticks).

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
Content-as-data	Designers ship levels/events without code	JSON/YAML packs

Decision Rule: Start with State Machine. Add ECS only when performance demands.

3. Input Abstraction

Abstract input into ACTIONS, not raw keys:

"jump"  → Space, Gamepad A, Touch tap
"move"  → WASD, Left stick, Virtual joystick

4. Illustrative Performance Budget (60 FPS = 16.67ms)

System	Budget
Input	1ms
Physics	3ms
AI	2ms
Game Logic	4ms
Rendering	5ms
Buffer	1.67ms

Profile CPU and GPU paths on target hardware before choosing an optimization; these techniques do not have a universal priority order.

5. AI Selection by Complexity

AI Type	Complexity	Use When
FSM	Simple	3-5 states, predictable behavior
Behavior Tree	Medium	Modular, designer-friendly
GOAP	High	Emergent, planning-based
Utility AI	High	Scoring-based decisions

6. Collision Strategy

Type	Best For
AABB	Rectangles, fast checks
Circle	Round objects, cheap
Spatial Hash	Many similar-sized objects
Quadtree	Large worlds, varying sizes

Anti-Patterns (Universal)

Don't	Do
Update everything every frame	Use events, dirty flags
Create objects in hot loops	Object pooling
Cache nothing	Cache references
Optimize without profiling	Profile first
Mix input with logic	Abstract input layer
Pick an engine by hype	Match engine to genre + team + delivery target

Routing Examples

“Browser 2D platformer”

→ game-development/engine-selection → game-development/web-games → game-development/2d-games → game-development/game-design

“UI-heavy web game with small arcade challenges”

→ game-development/engine-selection (shell vs guest) → game-development/web-games → game-development/2d-games for guests only

“Mobile puzzle”

→ game-development/mobile-games → game-development/game-design

“Multiplayer VR shooter”

→ game-development/vr-ar → game-development/3d-games → game-development/multiplayer

“Branching narrative with light stats”

→ game-development/engine-selection (Ink/Twine) → host UI of your choice

Remember: Great games come from iteration, not perfection. Prototype fast, then polish.

Limitations

Use this skill only when the task clearly matches the scope described above.
Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.

FAQ

What does the game-development skill do?

How do I install game-development?
