What problem does it solve? Test generation agents need accurate, language-specific knowledge about build commands, test frameworks, mocking patterns, and common errors. This Skill centralizes that guidance into per-language reference files so code-testing agents can load exactly the right instructions for the target language instead of guessing. ## Core Features & Use Cases - Language Extension Files: Provides dedicated guidance files for .NET, Python, TypeScript, PowerShell, C++, Go, Java, Rust, Ruby, Swift, and Kotlin covering build/test commands, framework detection, mocking, and common errors. - Pipeline Examples: Ships concrete end-to-end examples (research output, plan, generated tests, fix cycles, final report) for .NET, Python, TypeScript, Go, Java, and C++. - Use Case: A code-testing agent about to generate tests for a Go module calls this Skill, reads extensions/go.md for table-driven test patterns and go test command guidance, then reads extensions/go-examples.md to model its research, plan, and report output. ## Quick Start Call the code-testing-extensions skill to get the file path for your target language, then read that extension file before writing any test code.
