What problem does it solve? Code-testing agents need language-specific build commands, test frameworks, and error patterns, but that guidance varies widely across ecosystems. This Skill centralizes discovery of per-language extension files so testing pipelines load the right reference material for the target language. ## Core Features & Use Cases - Language Extension Discovery: Returns file paths to guidance files for .NET, Python, TypeScript, PowerShell, C++, Go, Java, Rust, Ruby, Swift, and Kotlin. - End-to-End Examples: Provides concrete pipeline walkthrough files (research, plan, generated tests, fix cycles, final report) for .NET, Python, TypeScript, Go, and Java. - Use Case: A code-testing agent targeting a Java repository calls this Skill, receives the path to java.md and java-examples.md, then reads them to learn Maven/Gradle commands, JUnit 5 detection, and Mockito patterns before writing tests. ## Quick Start Ask the code-testing pipeline to load the extension guidance for your target language, for example request the Go testing extension files before generating tests for a Go project.
