C# coding standards and code review. Use when the user mentions coding standards or conventions, writing code to spec, defining standards for a project, cohesion and coupling, design pattern selection, or naming conventions, or wants a code review on the design and standards dimension.

C# zero-GC engineering plans. Use when the user asks to make a system allocation-free, or mentions zero-GC, zero allocation, GC spikes, per-frame allocation budgets, object pooling systems, or preventing GC regressions. Produces a plan with commitment levels, acceptance criteria and regression guards, not a one-off code fix.

Unity performance optimization. Use when the user asks to optimize a class, view, function, folder or an entire module, or mentions stutter, lag, frame drops, low FPS, jank, overheating, battery drain, GC allocation, memory leaks, DrawCalls, batching, overdraw, slow loading, large build size, Profiler, PerfDog, or crash rates. Also covers pure C# micro-optimization: algorithmic complexity, memory layout, SIMD, and compiler-level tuning.
