Use this agent when working with C# code, including: - Implementing new features in C# projects - Refactoring existing C# codebases for clarity, performance, or maintainability - Writing or improving xUnit tests with FluentAssertions and Moq - Setting up .NET projects, solutions, or build configurations - Reviewing C# code for quality, idioms, test coverage, and security - Configuring Roslyn analyzers, StyleCop, .editorconfig, or other static analysis tools - Generating or updating DocFX documentation - Running quality gates: dotnet build, dotnet test, dotnet format, vulnerability scans - Designing APIs (minimal APIs, ASP.NET Core, dependency injection patterns) - Applying functional core/imperative shell architecture - Ensuring all code changes pass comprehensive quality checks before completion **Examples of when to invoke this agent:** <example> Context: User is building a new feature in a C# web API. user: "I need to add an endpoint that retrieves customer orders with pagination" assistant: "I'm going to use the Task tool to launch the csharp-craftsperson agent to implement this endpoint following minimal API patterns, functional core principles, and comprehensive testing." <commentary> The user needs a new API endpoint. The csharp-craftsperson agent will implement it idiomatically with proper DI, tests, and documentation. </commentary> </example> <example> Context: User has just written a significant chunk of C# code implementing a payment processing service. user: "I've finished the PaymentProcessor class" assistant: "Let me use the csharp-craftsperson agent to review the implementation for code quality, test coverage, adherence to functional core principles, and run all quality gates." <commentary> After a logical code chunk is complete, proactively invoke the agent to ensure quality standards are met before moving forward. </commentary> </example> <example> Context: User is starting a new C# project. user: "I want to create a new .NET service for handling inventory management" assistant: "I'll use the Task tool to launch the csharp-craftsperson agent to set up the project structure with proper solution organization, test projects, and quality tooling." <commentary> The agent will scaffold the project following best practices with SDK-style .csproj, xUnit tests, and appropriate analyzers. </commentary> </example> <example> Context: CI pipeline is failing due to code quality issues. user: "The build is failing on StyleCop warnings" assistant: "I'm going to use the csharp-craftsperson agent to analyze and fix the StyleCop violations while ensuring all quality gates pass." <commentary> The agent specializes in C# quality tooling and will resolve issues while maintaining code quality standards. </commentary> </example>
