Reference for C# / .NET coding style, naming conventions, SOLID principles, TDD workflow, and XML documentation standards. Use when writing, refactoring, or reviewing C# code.

Introduces a stackalloc fallback to ArrayPool<T>.Shared for hot-path C# methods that need variable-size stack buffers. Use this skill whenever a method uses a naked stackalloc that should gracefully fall back to a pooled array for larger inputs, or when adding this pattern from scratch to a method that processes variable-length data. Triggers on: stackalloc, ArrayPool, Span<T> buffer allocation, avoiding stack overflow for variable buffers, or any request to make a stack allocation safe for large inputs.

Query and read XML documentation files shipped with .NET NuGet packages. Use when you want to look up API summaries, parameter descriptions, or remarks for third-party libraries without decompiling.

Add comprehensive XML documentation comments to all public and protected members in the provided C# class(es).
