See [patterns.md](patterns.md) and [examples.md](examples.md) for detailed optimization techniques. ## 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 ## Related Skills - **unity-scene-optimizer**: For scene-level performance analysis - **unity-template-generator**: For generating validated script templates --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/dev-gom) — claim your Tome and manage your conversions.
