C# Scripts is cataloged under Automation on DirSkills. C# Scripts comes from a repository tagged agent-skills.

Excerpt

File-Based C# Apps

When to Use

Testing a C# concept, API, or language feature with a quick file-based app
Prototyping logic before integrating it into a larger project
Building a small utility from one entry-point file and a few helper .cs files

When Not to Use

The user asks for a language-agnostic quick script, throwaway computation, or shell/Python/PowerShell-style automation
The user needs a full project, solution integration, or project references in an existing app
The user is working inside an existing .NET solution and wants to add code there
The app is large enough that project structure, build customization, tests, or publish configuration should live in a .csproj

Inputs

The rest of the collection is listed on the dotnet/skills page.
How does C# Scripts compare to other Automation skills?
C# Scripts ranks #279 by stars among the 1523 Automation skills in this catalog. The most-starred ones next to it are Autonomous Loops, Autonomous Agent Harness and Automation Audit Ops.
