SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Legacy C# codebases often hide untestable static calls like DateTime.Now, File.*, and HttpClient throughout the code, making unit testing painful. This Skill audits your code and shows exactly where static coupling lives and how severe it is. ## Core Features & Use Cases - Static Dependency Detection: Scans .cs files for time, filesystem, environment, network, console, and process static call patterns. - Ranked Report: Produces category summaries, top 10 patterns by frequency, most affected files, and migration priorities. - Replacement Guidance: Maps each category to a recommended .NET abstraction such as TimeProvider, System.IO.Abstractions, or IHttpClientFactory. - Use Case: Before adding unit tests to a legacy solution, run a scan to find that DateTime.UtcNow appears 28 times across 14 files, then prioritize wrapping time statics first. ## Quick Start Scan the src/ directory of my C# solution for untestable static dependencies and give me a ranked report.

Frequently Asked Questions about detect-static-dependencies

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I find untestable static dependencies in C# code?▼

Scan your .cs files for patterns like DateTime.Now, File.ReadAllText, Environment.GetEnvironmentVariable, and new HttpClient(). This Skill searches a file, directory, project, or solution and returns a ranked report of static call sites by frequency.

What replaces DateTime.Now for testable C# code?▼

Use TimeProvider, which is built into .NET 8 and later, to abstract time access for unit testing. On earlier target frameworks, use NodaTime.IClock or a custom ISystemClock interface instead.

Can I scan only part of a .NET solution for static calls?▼

Yes, you can scope the scan to a single .cs file, a directory, a .csproj, or a full .sln. You can also filter by category such as time, filesystem, or network, and exclude paths with glob patterns.

Does the static dependency scan include test projects?▼

No, test projects matching *.Tests.csproj should be excluded so only production code is audited. The scan also always skips obj/ and bin/ directories and generated files like *.Designer.cs.

When should I not use a static dependency scan?▼

Skip it when statics are already behind interfaces or TimeProvider, when the code is not C#, or when you want wrappers generated or migration performed. Those tasks belong to wrapper-generation and migration skills instead.
