Game dev workflow

Game Dev Supercharger Workflow

Overview

This skill provides professional Unity game development workflows with AI-powered expert validation, automated asset generation, and performance profiling.

When to Use

Use this skill when:

• Making architectural decisions about Unity game systems
• Generating game assets (2D sprites, 3D models)
• Setting up Unity scenes with batch commands
• Validating game performance against platform targets
• Needing expert feedback on game design, architecture, or optimization

Available Tools

1. spawn_expert_panel

Get expert validation before making critical decisions.

Experts available:

• GameDesignExpert: Player psychology, game feel, engagement loops
• UnityArchitect: Unity patterns, architecture, best practices
• PerformanceEngineer: Optimization, frame budgets, profiling
• VisualDirector: Art direction, visual cohesion, asset quality

When to use:

• Before implementing major game systems
• When choosing between architectural approaches
• To validate asset visual coherence
• For performance optimization strategies

Example:

User: "Should I use Unity's Physics2D or custom physics for my arcade game?"

Claude: Let me consult the expert panel...
spawn_expert_panel(
  decision="Use Unity Physics2D with arcade tweaks",
  experts=["GameDesignExpert", "UnityArchitect", "PerformanceEngineer"],
  context="Arcade baseball game targeting mobile and web"
)

2. generate_2d_assets

Generate 2D game assets using AI (Gemini, Leonardo, FLUX).

When to use:

• Need sprites, icons, or UI elements
• Want multiple variations to choose from
• Prototyping visual style

Example:

generate_2d_assets(
  prompt="Baseball player sprite, batting pose",
  style="pixel art, 16-bit, retro",
  count=4,
  tool="gemini"  # Free 500/day
)

3. generate_3d_assets

Generate 3D models using AI (Meshy, Hunyuan3D).

When to use:

• Need 3D models for Unity scenes
• Prototyping environment props
• Creating unique game assets

Example:

generate_3d_assets(
  prompt="Baseball stadium bleachers, weathered wood",
  type="text_to_3d",
  tool="meshy"  # $20/mo subscription
)

4. unity_batch_command

Execute up to 25 Unity commands in parallel via Unity MCP.

When to use:

• Setting up Unity scenes
• Creating multiple GameObjects at once
• Batch importing assets
• Configuring scene hierarchies

Example:

unity_batch_command(
  commands=[
    {"tool": "manage_scene", "action": "create", "name": "Level1"},
    {"tool": "manage_gameobject", "action": "create",
     "name": "Player", "components": ["Rigidbody2D"]},
    {"tool": "manage_material", "action": "create",
     "name": "PlayerMat", "color": "#FF0000"}
  ]
)

5. validate_performance

Run Unity Profiler and validate against platform targets.

Platform targets:

• Mobile: 60 FPS, 16.67ms frame time, 100 draw calls
• Web: 30 FPS, 33.33ms frame time, 50 draw calls
• Desktop: 60 FPS, 16.67ms frame time, 500 draw calls

When to use:

• After implementing major features
• Before releasing builds
• When investigating performance issues
• To validate optimization efforts

Example:

validate_performance(
  platform="mobile",
  target_fps=60
)

Typical Workflows

New Feature Implementation

1. Brainstorm the approach
2. Spawn expert panel to validate architecture
3. Iterate based on expert feedback
4. Implement using Unity batch commands
5. Validate performance against targets

Asset Creation Pipeline

1. Generate 4-8 asset variations with AI
2. Review and select best options
3. Import to Unity with batch commands
4. Validate visual coherence with VisualDirector

Performance Optimization

1. Validate performance to identify issues
2. Spawn PerformanceEngineer for analysis
3. Apply suggested optimizations
4. Re-validate until targets met

Best Practices

1. Always consult experts before major decisions

   • Prevents costly architectural mistakes
   • Catches platform-specific issues early

2. Use batch commands for efficiency

   • 10-100x faster than individual API calls
   • Reduces development time significantly

3. Generate asset variations

   • AI can surprise with creative ideas
   • Having options improves final quality

4. Validate performance early and often

   • Don't wait until release to find issues
   • Test on target platform (mobile especially)

Prerequisites

• Unity MCP must be running (http://localhost:8080/mcp)
• API Keys configured in environment:
  • ANTHROPIC_API_KEY (required for expert panel)
  • GEMINI_API_KEY (optional, free 500/day)
  • LEONARDO_API_KEY (optional, free tier available)
  • MESHY_API_KEY (optional, $20/mo for 3D)
