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
