• •dotnet CLI for building
• •HttpClientFactory for HTTP
• •System.Text.Json/Newtonsoft.Json
• •Polly for resilience

Input Requirements

• •API specification
• •Target framework versions
• •Nullable reference types preference
• •HTTP client preference
• •Dependency injection requirements

Output Artifacts

Usage Example

skill:
  name: csharp-sdk-specialist
  context:
    apiSpec: ./openapi.yaml
    targetFrameworks:
      - netstandard2.0
      - net6.0
      - net8.0
    nullableEnabled: true
    useSourceLink: true
    jsonSerializer: system-text-json

Best Practices

1. •Use async/await with ConfigureAwait(false)
2. •Support CancellationToken in all async methods
3. •Implement IDisposable/IAsyncDisposable properly
4. •Use nullable reference types
5. •Provide extension methods for DI registration
6. •Include comprehensive XML documentation
