Split a large test file into several smaller, logically-grouped files. Use this skill whenever the user wants to break up, divide, or refactor a big test file (especially Vitest + React/TypeScript tests) into smaller files — for example when a test file exceeds a few hundred lines, when the user mentions splitting tests "by feature" or "by component", or when they ask to make test files smaller or more maintainable. Trigger it even if the user doesn't say the word "split" explicitly, as long as the intent is to reorganize a large test file into multiple files.
