unity-foundations

unity-foundations is a skill for Claude Code from Nice-Wolf-Studio/unity-claude-skills. It costs 67 tokens per session (3,326 once invoked), scanned A, original, MIT.

A reference guide to Unity 6’s core building blocks and project structure. It explains how GameObjects, Components, Transforms, Scenes, Prefabs, and ScriptableObjects fit together.

In plain words
What is it for?
Use it when building or organizing Unity scenes, objects, reusable Prefabs, data assets, tags, layers, or custom Components.
Why use it?
It helps you understand where objects and behavior belong in a Unity project, reducing confusion when setting up scenes or writing scripts.

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-foundations 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 6d 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.

Unity Foundations

Core Concepts

GameObjects

GameObjects are the fundamental building blocks in Unity. Every object in a scene -- characters, props, scenery, cameras, lights -- is a GameObject. GameObjects are containers: they cannot function alone and require Components to gain functionality. Every GameObject automatically includes a Transform component that cannot be removed.

Components

Components are the functional pieces of every GameObject. Unity uses a composition-over-inheritance architecture: you build behavior by attaching multiple components to a GameObject rather than inheriting from deep class hierarchies. Each GameObject must have exactly one Transform component. Additional components (Rigidbody, Collider, MeshRenderer, custom MonoBehaviours) define what the object does.

Constraints from the docs:

  • Components must reside in the same project as their target GameObject
  • Components cannot be sourced from separate projects, unattached scripts, or uninstalled packages

Transforms

The Transform component stores position, rotation, and scale -- each relative to the parent (local coordinates) or to the world origin (world coordinates). Key points from the docs:

  • Child Transforms display values relative to their parent
  • Root GameObjects (no parent) show world coordinates
  • The physics engine assumes 1 unit = 1 meter
  • Set parent location to (0,0,0) before adding children so local coords match global coords
  • Avoid adjusting Transform Scale at runtime; model assets at real-life scale instead. Non-uniform scaling causes issues with Colliders, Lights, and Audio Sources

Scenes

Scenes are assets that contain all or part of a game or application. A default new scene includes a Camera and a directional Light. Projects can use a single scene or multiple scenes (e.g., one per level). Scene Templates serve as blueprints for creating new scenes.

Prefabs

Prefabs are reusable asset templates that store a complete GameObject configuration (all components, property values, and child GameObjects). Key features:

  • Nested Prefabs: Include prefab instances within other prefabs
  • Prefab Variants: Create predefined variations that maintain a base prefab relationship
  • Overrides: Modify components/data on specific instances without affecting the template
  • Unpacking: Convert prefab instances back to standalone GameObjects

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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-foundations is a skill published in the GitHub repository Nice-Wolf-Studio/unity-claude-skills (30 stars, last pushed 1mo ago), licensed MIT. It adds 67 tokens to every session and 3,326 once invoked, about $0.0003 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.
