Unity Script Validator

Unity Script Validator

Validates Unity C# scripts against best practices and performance patterns specific to Unity game development.

What This Skill Checks

• Field declarations: [SerializeField] private instead of public fields
• Component caching: GetComponent in Awake/Start, not Update (~100x faster)
• String operations: StringBuilder for frequent concatenation
• GameObject.Find: Cache references, avoid in Update (O(n) operation)
• Code organization: #region directives, consistent ordering
• XML documentation: <summary> tags on public methods
• Update vs FixedUpdate: Appropriate usage for physics/non-physics
• Coroutines: Prefer for intermittent tasks over Update

Provides: Issues found, specific fixes, performance impact estimates, refactored code examples.

Compatibility

Applies to Unity 2019.4 LTS and later (including Unity 6).

See patterns.md and examples.md for detailed optimization techniques.
