unity

unity is a skill for Claude Code from MonumentalSystems/Atlas-Agent-Teams. It costs 13 tokens per session (1,074 once invoked), scanned A, original, MIT.

A reference skill for building projects in Unity, a game engine, including project structure, reusable game objects, scenes, settings, and C# scripts.

In plain words
What is it for?
Use it when organizing Unity projects, working with scenes, prefabs, components, physics, rendering, input, or Unity script lifecycle methods.
Why use it?
It gives the agent shared terminology and workflows for Unity projects and 3D asset integration.

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

unity 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 7d 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.

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Unity Engine

Unity Fundamentals

Project Structure

  • Assets Folder: Contains all project assets (models, textures, materials, scripts)
  • Scenes: Individual levels or environments
  • Prefabs: Reusable game object templates
  • Packages: External libraries and tools via Unity Package Manager
  • Project Settings: Global configuration for physics, graphics, input, etc.

GameObject Hierarchy

  • Transform: Position, rotation, and scale of objects
  • Parent-Child Relationships: Object hierarchy for organization and transformation
  • Components: Modular functionality attached to GameObjects
  • Tags and Layers: Organization and filtering for game logic

Unity Scripting and C# Basics

MonoBehaviour Lifecycle

  • Awake(): Called when script instance is loaded
  • Start(): Called before first Update frame
  • Update(): Called once per frame
  • FixedUpdate(): Called at fixed time intervals for physics
  • LateUpdate(): Called after all Update calls complete
  • OnDestroy(): Called when GameObject is destroyed

Common Unity APIs

  • Transform: Access position, rotation, scale
  • Rigidbody: Physics simulation
  • Collider: Collision detection
  • Renderer: Visual rendering control
  • Animation: Animation playback control
  • Animator: State machine for animations

Prefab and Component Architecture

Prefabs

  • Creating Prefabs: Drag GameObject to Project window
  • Prefab Variants: Inherit from base prefab with overrides
  • Nested Prefabs: Prefabs containing other prefabs
  • Prefab Mode: Edit prefabs in isolation
  • Prefab Overrides: Apply or revert changes to prefabs

Components

  • Mesh Renderer: Renders 3D meshes
  • Mesh Filter: Holds mesh data
  • Skinned Mesh Renderer: Renders animated meshes
  • Animator: Controls animation playback
  • Rigidbody: Physics simulation
  • Collider: Collision detection

Unity Asset Pipeline and Addressables

Asset Import

  • Model Import Settings: Scale, normals, tangents, animation clips
  • Texture Import Settings: Compression, max size, mipmaps
  • Audio Import Settings: Compression, load type, format
  • Asset Bundles: Package assets for runtime loading

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.

unity is a skill published in the GitHub repository MonumentalSystems/Atlas-Agent-Teams (21 stars, last pushed 26d ago), licensed MIT. It adds 13 tokens to every session and 1,074 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
