csharp skillA
csharp is agent-read markdown (skill) from jnpiyush/agentx: Write production-ready C# and .NET code following modern best practices. Use when building .NET applications, writing async/await code, using Entity Framework Core, implementing dependency injection, configuring nullable reference types, or optimizing C# performance..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
