What its author says it does
Copied from the file, not written here
Provides file paths to language-specific extension files for the code-testing pipeline. Call this skill to discover available extension guidance files (e.g., dotnet.md for .NET, cpp.md for C++). Do not use directly — invoked by code-testing agents and skills that need language-specific references.
The file declares its own license as MIT. That is the author’s claim about this one file, and it is not the same thing as the license GitHub reports for the repository, which is listed with the other numbers below.

Code Testing Extensions
This skill provides access to language-specific guidance files used by the code-testing pipeline. Call this skill to get the file paths, then read the relevant file for your target language.
Available Extension Files
| File | Language | Contents |
|---|---|---|
| extensions/dotnet.md | .NET (C#/F#/VB) | Build commands, test commands, project reference validation, common CS error codes, MSTest template |
| extensions/python.md | Python | Framework-adaptive test commands (pytest, custom runners), project layout detection, mocking guidelines, common errors |
| extensions/typescript.md | TypeScript/JavaScript | Build/test commands (Jest/Vitest/Mocha), framework detection, mocking, TS-specific considerations |
| extensions/powershell.md | PowerShell | Test commands (Pester v5), module import patterns, discovery/run pitfalls, mocking, common errors |
| extensions/cpp.md | C++ | Testing internals with friend declarations |
| extensions/go.md | Go | go test commands, table-driven tests, integration vs unit layout, mocking via interfaces, common errors |
| extensions/java.md | Java | Maven/Gradle commands, JUnit 4/5 and TestNG detection, Mockito, Spring Boot slices, common errors |
| extensions/rust.md | Rust | cargo test commands, unit vs integration vs doc tests, features, async test harnesses, common errors |
| extensions/ruby.md | Ruby | RSpec and Minitest commands, Bundler usage, Rails specifics, mocking patterns, common errors |
| extensions/swift.md | Swift | SPM and Xcode test commands, XCTest vs Swift Testing, @testable import, async/throws tests, common errors |
| extensions/kotlin.md | Kotlin | Gradle commands, JUnit/Kotest detection, MockK, coroutines test, KMP and Android specifics, common errors |
| extensions/dotnet-examples.md | .NET (C#/F#/VB) | Concrete pipeline examples: sample research output, plan, generated tests, fix cycles, final report |
| extensions/python-examples.md | Python | Concrete pipeline examples (pytest): research, plan, generated test file, fix cycles, final report |
| extensions/typescript-examples.md | TypeScript/JavaScript | Concrete pipeline examples (Vitest, applicable to Jest): research, plan, generated test file, fix cycles, final report |
| extensions/go-examples.md | Go | Concrete pipeline examples (standard testing): research, plan, table-driven test file, fix cycles, final report |
| extensions/java-examples.md | Java | Concrete pipeline examples (JUnit 5 + Mockito on Maven): research, plan, generated test file, fix cycles, final report |
Usage
Read the appropriate extension file for the target language before writing test code. When an <language>-examples.md file exists for the target language, read it alongside the base extension to see a concrete end-to-end pipeline walkthrough (research output, plan, generated tests, fix cycles, final report).
