This wraps ILSpy's command-line decompiler so Claude can inspect .NET assemblies for you. Point it at a DLL from NuGet packages, your build output, or the runtime itself, and it'll show you the actual C# implementation behind any API. Useful when documentation is thin or you need to understand why something behaves the way it does. The skill covers both standalone ilspycmd and the dnx version, walks through common assembly locations, and reminds you about gotchas like trimmed builds producing incomplete output. Just be aware that decompiling code you don't own can have licensing implications depending on what you're looking at.
