Generates and writes new unit tests for any programming language using a Research-Plan-Implement pipeline. Use when asked to generate tests, write unit tests, add tests, improve test coverage, create test project, achieve high coverage, comprehensive tests, or asked to scaffold a new test project for an app, service, or library. Supports C#, TypeScript, JavaScript, Python, Go, Rust, Java, and more. Orchestrates the code-testing-generator sub-agent through research, planning, and implementation phases so tests compile, pass, and follow project conventions. DO NOT USE FOR: running existing tests or test filters (use run-tests); diagnosing coverage plateaus or project-wide coverage/CRAP analysis without writing tests (use coverage-analysis); targeted method/class CRAP scores (use crap-score); MSTest assertion guidance, MSTest test pattern modernization, or fixing existing MSTest test code (use writing-mstest-tests).
This skill does not declare a tool allowlist. The agent host applies whatever default tools are available at runtime.
