What problem does it solve? Automated test generation agents need accurate, language-specific build commands, test framework conventions, mocking patterns, and error fixes. This Skill centralizes that guidance so code-testing agents can load the right reference file for the target language instead of guessing commands or frameworks. ## Core Features & Use Cases - Language Extension Files: Reference documents for .NET, Python, TypeScript, PowerShell, C++, Go, Java, Rust, Ruby, Swift, and Kotlin covering build/test commands, framework detection, mocking rules, and common errors. - End-to-End Pipeline Examples: Concrete walkthroughs for .NET, Python, TypeScript, Go, Java, and C++ showing research output, plans, generated test files, fix cycles, and final reports. - Use Case: A code-testing agent targeting a Go repository reads go.md to learn table-driven test conventions, go test -run regex anchoring, and interface-based fakes, then reads go-examples.md to mirror a complete pipeline run. ## Quick Start Ask the code-testing agent to load the extension file matching your project's language before generating any tests.
