SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill provides instant feedback for small C# fragments and scratch code by evaluating snippets without loading a full solution, enabling rapid validation and prototyping.

Core Features & Use Cases

  • Ephemeral analysis and execution: analyze snippets with compile-time diagnostics and lightweight execution to surface results quickly.
  • Explain mode: offer step-by-step semantic walkthroughs of code when requested to teach or debug.
  • Lightweight workflow guidance: recommend workspace_load only when full project context is necessary.

Quick Start

Analyze a short C# fragment or point at a scratch file to get immediate feedback.

FAQPage Schema
How do I get quick C# feedback without loading a full solution?

To get quick C# feedback without loading a solution, you can analyze short code fragments using snippet evaluation. This provides immediate compile-time diagnostics and lightweight execution for rapid validation.

Can I prototype and execute isolated C# expressions instantly?

Yes, you can prototype isolated C# expressions by evaluating snippets. This allows you to execute lightweight code fragments and surface results quickly without needing a full project context.

How do I get a step-by-step semantic explanation for a C# snippet?

To get a step-by-step semantic explanation for a C# snippet, you can use the optional explain mode. This offers a detailed walkthrough of the code to help you teach or debug isolated fragments.

What's the best way to analyze short C# fragments for syntax and semantic validation?

The best way to analyze short C# fragments for syntax and semantic validation is to use a snippet analyzer. It binds and evaluates the code to surface compile-time diagnostics rapidly without a heavy workspace.

When should I load a full workspace instead of evaluating a C# snippet?

You should load a full workspace instead of evaluating a C# snippet when your code requires real-project context. If the snippet analysis lacks necessary project dependencies, workspace loading is recommended for accurate results.
