Unity ECS Patterns

What your AI can do with it

• Apply ECS patterns to structure entities and components
• Use DOTS to organize data-oriented game code
• Write Jobs for parallel processing of entity data
• Add Burst compilation for performance-critical code
• Handle large entity counts with ECS architecture

Getting started

1. Have a Unity project that uses the Entity Component System packages.
2. Add the unity-ecs-patterns skill to your agent configuration.
3. Ask your agent to apply ECS patterns when writing or reviewing game code.
4. Provide the agent with your entity and component definitions for context.

What this skill tells your AI

The instructions your AI receives, as published by wshobson/agents in plugins/game-development/skills/unity-ecs-patterns/SKILL.md and read by ahel’s review.

Entity: Lightweight ID (no data)
Component: Pure data (no behavior)
System: Logic that processes components
World: Container for entities
Archetype: Unique combination of components
Chunk: Memory block for same-archetype entities

Questions

What is unity-ecs-patterns?

It is a skill that guides your agent in building high-performance Unity games using ECS, DOTS, Jobs, and Burst. It helps with data-oriented game development, performance optimization, and large entity counts.

When should I use this skill?

Use it when building data-oriented games, optimizing performance, or working with large entity counts in Unity. It provides patterns for ECS, DOTS, Jobs, and Burst.

Does it support other game engines?

No. The skill is specific to Unity and its ECS, DOTS, Jobs, and Burst technologies.

Can it help with existing Unity projects?

Yes. The skill can guide your agent in applying ECS patterns to new or existing Unity projects that use the Entity Component System.
