SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Large Unity projects often suffer from long compile times and tangled dependencies as they scale. This Skill guides you to define modular assembly definitions that improve build performance, enforce clean boundaries, and separate editor/runtime/test concerns.

Core Features & Use Cases

  • Recommend a minimal set of asmdef assemblies to reduce compile times and maintain clear boundaries.
  • Define allowed dependency direction to prevent circular references and improve project organization.
  • Provide migration steps for moving existing code to new assembly structure, while preserving behavior.

Quick Start

Create a plan to split your Unity project into modules by proposing an initial asmdef setup for core, gameplay, editor, and runtime boundaries.

Frequently Asked Questions about unity-asmdef

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I reduce compile times in large Unity projects?▼

Defining modular assembly boundaries reduces Unity compile times by isolating code into smaller assemblies. This Skill proposes a minimal set of asmdef files to enforce clear boundaries, separating editor, runtime, and test code to speed up builds.

How do I prevent circular dependencies when setting up Unity assembly definitions?▼

Preventing circular dependencies in Unity assembly definitions requires defining allowed dependency directions. This Skill configures directional references between assemblies to improve project organization and avoid circular references during migration.

What is the best way to separate editor and runtime code in Unity?▼

Separating editor and runtime code in Unity is achieved through assembly definitions. This Skill identifies and configures asmdef files to enforce clear editor, runtime, and test boundaries, ensuring modular separation across large projects.

How do I migrate existing code to a new Unity assembly structure?▼

Migrating existing code to a new Unity assembly structure requires structured steps to preserve behavior. This Skill provides migration steps for moving code into proposed asmdef assemblies while maintaining functional consistency.

Do I need assembly definitions for small Unity projects?▼

Assembly definitions are primarily needed for large Unity projects requiring clear module boundaries and build optimization. Small projects without tangled dependencies or long compile times generally do not require structured asmdef migration steps.
