C#/.NET SDK Specialist Skill
Overview
This skill specializes in developing .NET SDKs with proper async/await patterns, supporting .NET Standard, .NET Core, and .NET 6+ with NuGet distribution.
Capabilities
- Design .NET SDK architecture with modern patterns
- Implement async/await patterns with proper cancellation
- Configure NuGet package publishing
- Support .NET Standard 2.0/2.1, .NET Core 3.1, .NET 6/7/8
- Design extension methods for fluent APIs
- Implement dependency injection patterns
- Configure XML documentation for IntelliSense
- Support source link for debugging
Target Processes
- Multi-Language SDK Strategy
- SDK Architecture Design
- SDK Testing Strategy
Integration Points
- NuGet package registry
- xUnit/NUnit for testing
- 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
- .NET SDK source code (.csproj)
- NuGet package specification
- xUnit test project
- XML documentation
- Example console application
- README with installation
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
- Use async/await with ConfigureAwait(false)
- Support CancellationToken in all async methods
- Implement IDisposable/IAsyncDisposable properly
- Use nullable reference types
- Provide extension methods for DI registration
- Include comprehensive XML documentation
Recommended Agent Skills
Expand your agent's capabilities with these related and highly-rated skills.
gsd-tools
Central utility skill for GSD operations. Provides config parsing, slug generation, timestamps, path operations, and orchestrates calls to other specialized skills. Acts as the unified entry point that the original gsd-tools.cjs provided via its lib/ modules (commands, config, core, init).
model-profile-resolution
Resolve model profile (quality/balanced/budget) at orchestration start and map agents to specific models. Enables cost/quality tradeoffs by selecting appropriate AI models for each agent role.
verification-suite
Plan structure validation, phase completeness checks, reference integrity verification, and artifact existence confirmation. Provides the structured verification layer ensuring GSD artifacts are well-formed and complete.
state-management
STATE.md reading, writing, and field-level updates. Provides cross-session state persistence via .planning/STATE.md with structured fields for current task, completed phases, blockers, decisions, and quick tasks.
git-integration
Git commit patterns, formats, and conventions for GSD methodology. Provides atomic commits per task, structured commit messages, planning file commits, branch management, and milestone tag operations.
frontmatter-parsing
YAML frontmatter parsing and manipulation for .planning/ documents. Provides read, write, update, query, and validation operations on frontmatter blocks in GSD markdown artifacts.
