Unity SpriteAtlas V2

Provides editor-safe procedural knowledge for scripting atlases in Unity projects. V2 enforces strict separation between editor authoring and runtime access.

⚠️ Critical V2 Principle: SpriteAtlas is runtime-only. SpriteAtlasAsset is editor-only. Never mix contexts. Always use V2.

🚨 CRITICAL: Required Checks and User Inputs Before Implementation

ALWAYS perform these checks and ask these questions BEFORE generating any code:

Read the shipped resources before writing code (REQUIRED)

This skill ships working C# under resources/, and the atlas code that goes wrong is almost always code written without reading it first. Open the files for the path you are taking, then write.
