What it does

When installed, the agent reviews or writes .NET and C# code with a checklist of conventions in mind: XML documentation comments, dependency injection with constructor null checks, async/await for I/O, MSTest with FluentAssertions and Moq for tests, structured logging, localized resource strings, and SOLID-style design. It applies these to the code you select or point it at, so output follows typical .NET project conventions instead of generic C#.

Great for

  • C# developers working on .NET 8 projects who want consistent code style
  • Teams that already use MSTest, FluentAssertions, Moq and Microsoft.Extensions.* libraries
  • Developers adding tests or documentation to existing .NET code

Skip it if

  • Projects using different frameworks (e.g. xUnit, NUnit, NSubstitute) or older .NET versions, since the rules assume MSTest, Moq and C# 12/.NET 8; the agent may push the wrong conventions
  • Teams that want strict, verified compliance; the skill is a set of guidelines, not an analyzer, so it can miss issues or suggest changes that do not fit the codebase

Try asking

  • “Review the selected C# class and suggest changes to match .NET best practices”
  • “Add XML documentation comments to all public methods in this service”
  • “Write MSTest unit tests with FluentAssertions and Moq for this handler, including null checks”
  • “Refactor this class to use constructor dependency injection and async/await for I/O”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Select the specific code or file you want reviewed so the ${selection} placeholder has useful input
  • Tell the agent which test framework and DI setup your project actually uses, since the skill defaults to MSTest and Moq
  • Treat suggestions as a starting point and run your build and tests before accepting changes
