Use it when you build a data-oriented Unity game, move OOP game code to ECS, or speed up CPU-heavy game logic. SKILL.md explains the core terms (entity, component, system, world, archetype, chunk) and a short do and don't list. Claude is told to prefer ISystem over SystemBase, Burst-compile systems, batch structural changes with command buffers and avoid managed types.

A detail file holds eight C# patterns: basic setup, ISystem systems, entity queries, command buffers, aspects, singletons, baking from GameObjects, and jobs with native collections. It ends with performance tips. The skill bundles no scripts.

Good for

Unity developers building games with thousands of entities
Teams converting GameObject code to ECS
Developers tuning CPU-bound game logic with Jobs and Burst

Install unity-ecs-patterns

Claude Code

Copy this prompt.

Install the unity-ecs-patterns skill in Claude Code. Run this command:

/plugin marketplace add wshobson/agents
/plugin install game-development@claude-code-workflows

Then check that it loaded and tell me how to use it.

Paste it into Claude Code. It shows the change and asks before running it.

The plugin is game-development. It holds 2 skills and 2 agents, and its plugin.json lists no hooks or MCP servers. Pick one route, not both. The README says the skills-only routes install the skill without the plugin's agents, commands or hooks.

Questions

What does the skill do?

It teaches Claude Unity DOTS patterns. That means entities, components and systems, ISystem, queries, entity command buffers, aspects, singletons, baking, and jobs with Burst and native collections.

How do I install it?

Use the install box above. The skill is part of the game-development plugin in the wshobson/agents collection. Use the plugin route or one of the skills-only commands.

What else comes with the plugin?

The game-development plugin holds 2 skills and 2 agents in the repo, per its folder listing, with no commands. The other skill covers Godot GDScript and the agents are for Unity and Minecraft Bukkit. Its plugin.json names no hooks or MCP servers.

Does it need an API key or tools?

No key or tool is mentioned. The skill bundles no scripts. It is guidance and C# examples for Claude to follow.

Is it safe?

It bundles no scripts and only guides how Claude writes code. Review the C# it generates before you add it to your project.

What are the main rules it gives?

Use ISystem over SystemBase, Burst compile everything, batch structural changes with a command buffer, and use aspects for component groups. Do not use managed types, make structural changes in jobs, over-design, or forget to dispose native collections.
