# 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).
|
|
|
|

## When to Use vs Other Components
|
|
|
|
**Use this Skill when**: Quick validation of existing Unity scripts for best practices and common issues
|
|
|
|
**Use @unity-scripter agent when**: Writing new code or implementing Unity features from scratch
|
|
|
|
**Use @unity-refactor agent when**: Improving code quality, applying design patterns, or modernizing legacy code
|
|
|
|
**Use @unity-performance agent when**: Deep performance profiling, memory optimization, or platform-specific tuning
|
|
|
|
**Use /unity:new-script command when**: Creating new scripts from production-ready templates
|
