csharp-expert

Route C# and .NET requests to the exact installed specialist or smallest dotnet/skills marketplace plugin. USE FOR: "which specialist should own this" or "how do I add the skill" requests involving ASP.NET Core endpoints, Blazor, MAUI binding, Windows Forms specialist selection or installation, EF Core queries, test or framework migration, runtime CPU/allocation evidence, file-based C#, editor/compiler defects, a surviving MSBuild `.binlog`, or a plugin missing from `/skills`; also use for C# semantics when no narrower specialist exists. DO NOT USE FOR: requests that already name the exact installed specialist to invoke, or work unrelated to C# or .NET.

# C# Expert

## Purpose

Act as the front door for C# and .NET work. Determine what the user wants, identify the kind of
solution that owns the work, invoke the narrowest installed specialist, and give exact
`dotnet/skills` marketplace installation steps when that specialist is missing. Keep direct C#
language guidance as the fallback, not the default.

## Routing Contract

1. Classify the requested outcome from the prompt.
2. Inspect the smallest set of repository files needed to identify the solution type.
3. Compare both signals with the descriptions of the skills currently available to the runtime.
