Frequently Asked Questions About Piotr Błażejewicz (Peter Blazejewicz)
FAQPage SchemaWhat tasks can I accomplish with peterblazejewicz's .NET skills?▼
The 28 skills cover the full .NET/C# lifecycle: spec-driven planning, task breakdown, TDD with xUnit/MSTest, integration testing via WebApplicationFactory and Testcontainers, Avalonia UI engineering, API design, performance tuning with BenchmarkDotNet, security hardening, CI/CD pipelines, observability, code review, and production launches with rollback.
Who are these .NET skills designed for?▼
They target .NET/C# developers and engineers building ASP.NET Core APIs, Avalonia desktop/mobile apps, Blazor frontends, EF Core data layers, or NuGet libraries. They also serve reviewers and release engineers handling code quality gates, deployments, monitoring, and migration or deprecation decisions in multi-project solutions.
How do I invoke and use these skills in practice?▼
Each skill triggers on natural phrases or contexts, e.g. 'idea-refine' or 'ideate' for concept shaping, 'interview me' for requirement clarification, or automatic activation when dotnet test fails. The using-agent-skills meta-skill maps tasks across Define, Plan, Build, Verify, Review, and Ship phases to the right skill.
What prerequisites and dependencies do these skills require?▼
Skills assume a .NET 8+ environment with the dotnet CLI. Specific skills require xUnit v2/v3 or MSTest, Playwright or Avalonia.Headless for E2E tests, Testcontainers with PostgreSQL/SQL Server/Redis, GitHub Actions or Azure DevOps, and the chrome-devtools MCP server for browser testing with DevTools.
Are these .NET skills free and open source?▼
The manifest lists no license fees or commercial terms; skills are sourced from a vendor/agent-skills repository with versioned SKILL.md files (e.g., test-driven-development 1.0.1, review 1.1.0) and are distributed through the dotnet-skills marketplace for direct use in agent sessions.
