Usage
Read the appropriate base extension before writing test code. Load an `<language>-examples.md` file only when the repository has no representative tests and the base extension does not resolve the needed pattern. Do not load end-to-end examples for a focused request with established local conventions.

Questions about code-testing-extensions.
- Which coding agents can use code-testing-extensions?
- code-testing-extensions installs in Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and Windsurf with the skills CLI, using each agent's flag shown on this page. Flowy's auto-invocation, which fires a skill when your prompt matches, runs in Claude Code only.
