Unity Dev

unity-dev

A Claude Code plugin for Unity C# development with architecture design, coding guidelines, testing patterns, and specialized review agents.

Installation

/plugin install unity-dev@DmitriyYukhanov/claude-plugins

Dependencies

This plugin delegates to standard Claude Code plugins for enhanced functionality:

Agent	Delegates To	Purpose
unity-reviewer	feature-dev:code-reviewer	General code quality, logic, and bug detection
unity-simplifier	code-simplifier:code-simplifier	General code cleanup after Unity-specific patterns

Required plugins (install from official marketplace):

/plugin install feature-dev
/plugin install code-simplifier

The Unity agents apply domain-specific patterns first, then delegate to general-purpose agents for comprehensive coverage.

Features

Command: /unity-dev

Orchestrates a complete Unity development workflow:

1. Discovery - Analyzes project structure and requirements
2. Architecture - Designs component hierarchies, interfaces, test stubs, Mermaid diagrams
3. Implementation - Follows Unity C# coding guidelines
4. Review - Unity-specific code review for performance, lifecycle, serialization issues
5. Testing - EditMode and PlayMode test patterns

Command: /unity-tests-run

Runs Unity Test Framework tests via CLI batchmode with auto-detection of Unity installation. Supports platform, category, and filter arguments.

Skills (Reference Knowledge)

• unity-architect - Architecture patterns, Mermaid diagrams, test stub templates
• unity-coder - C# naming conventions, member ordering, Unity-specific guidelines
• unity-tests-write - EditMode/PlayMode patterns, performance testing, code coverage

Agents (Autonomous Tasks)

• unity-reviewer - Unity-specific review, then chains to feature-dev:code-reviewer
• unity-simplifier - Unity patterns, then chains to code-simplifier:code-simplifier
• unity-test-runner - Runs Unity tests via CLI batchmode (used by /unity-tests-run)

Usage

# Full development workflow
/unity-dev Add player health system with damage and healing

# Individual phases
/unity-dev architect only - Design a save system
/unity-dev review only - Review recent changes

What It Checks

Performance

• Uncached GetComponent in Update loops
• Allocations in hot paths (LINQ, string concatenation)
• Missing object pooling

Lifecycle

• Proper Awake/Start/OnEnable/OnDisable/OnDestroy usage
• Event subscription/unsubscription symmetry
• Static state cleanup with [RuntimeInitializeOnLoadMethod]

Serialization

• Correct use of [SerializeField] and [field:SerializeField]
• Missing [System.Serializable] on nested classes

Platform

• IL2CPP compatibility (no runtime reflection)
• Platform-specific #if directives
