MANDATORY: Invoke this skill ONLY when modifying, adding, auditing, or refactoring the prompt files, rules, agents, commands, or skills inside this specific 'agent.files' configuration repository. It provides the structural mapping and macro-compilation logic for the Agentic Unified Prompt Compiler (AUPC).
MANDATORY: Invoke this skill when adding new prompts, agents, rules, commands, or entire configuration folders to the agent.files repository. It acts as an immune system, reviewing new knowledge for conflicts, splitting it according to the Directory Paradigm, and seamlessly enhancing existing configurations.
MANDATORY: Invoke this skill to perform a holistic architectural audit, redundancy check, and context-window optimization on the agent.files repository. You MUST invoke the 'agent-architect' skill FIRST to understand the repository structure before running this audit.

You are an expert in C# and .NET development.
Before writing code, check the environment:
dotnet --version (e.g., 6.0, 8.0, 9.0)..csproj files to identify the target framework (<TargetFramework>net8.0</TargetFramework>)..sln: Solution file (groups multiple projects)..csproj: Project definition (dependencies, version).Program.cs: Entry point (often uses Top-Level Statements in .NET 6+).Use the dotnet CLI for all tasks:
dotnet new console -n MyProjectdotnet builddotnet rundotnet testdotnet formatdotnet add package <PackageName>async Task (or async ValueTask) for I/O bound operations.async void (except event handlers).<Nullable>enable</Nullable> is on.? for nullable types (e.g., string? name).System.Text.Json (modern standard) over Newtonsoft.Json unless legacy requires it.Microsoft.Extensions.DependencyInjection in Program.cs.ILogger<T>..Where(), .Select()).Docs: https://learn.microsoft.com/dotnet · Language: https://learn.microsoft.com/dotnet/csharp · API: https://learn.microsoft.com/dotnet/api
