Use this skill when

• Writing C# scripts for gameplay, UI, physics, or networking
• Optimizing performance for Android/iOS/WebGL
• Making architecture and design pattern decisions

Critical Performance Rules

1. NEVER Find()/GetComponent() in Update() — cache in Awake()/Start()
2. Object pooling for frequently spawned/destroyed objects
3. StringBuilder for string concatenation in hot paths
4. CompareTag() instead of == "tag"
5. Cache WaitForSeconds — don't allocate every frame
6. No LINQ in Update/FixedUpdate — causes GC allocations
7. [SerializeField] private over public for Inspector fields
8. No Camera.main in loops — cache the reference

Architecture Patterns (QuizVerse)

• Singleton: QuizManager.Instance?.Method() — always null-safe
• Events: C# events (OnEnable +=, OnDisable -=) for memory safety
• Layer rule: UI → Manager → Service → Backend (never skip layers)
• ScriptableObject for data-driven config
• State machines for game state and character control

Script Role Convention

Async Decision Ladder

1. Event-driven? → C# events/callbacks (PREFERRED)
2. Unity-bound sequence? → Coroutine (QUIZVERSE DEFAULT)
3. Need cancellation? → async/await + CancellationToken
4. Continuous simulation? → Update (last resort)

Mobile Performance Checklist

• Texture sizes appropriate (max 2048 for UI, 1024 for sprites)
• Draw calls batched (check Frame Debugger)
• No string alloc in Update loops
• Safe Area handled for notches (Screen.safeArea)
• No reflection in hot paths (IL2CPP compatibility)

Inspector Design

[Header("Configuration")]
[Tooltip("Description")]
[SerializeField, Range(1, 10)] private int _value = 3;

[Header("References")]
[SerializeField] private Transform _target;
