Write strategic, behavior-focused tests for core user flows and critical functionality using Vitest for unit tests and Playwright for end-to-end testing. Use this skill when writing test files, testing utilities, or implementing test coverage for critical paths. When working on Vitest test files (.test.ts, .spec.ts), Playwright E2E test suites, test setup and configuration files (vitest.config.ts, test-setup.ts), mock implementations for external dependencies, testing utility functions or test helpers, component test files using React Testing Library, API route test files, or integration tests for Content Collections and data fetching logic.

"Am I *doing* or just *describing* that I should do?" - Counters documentation-over-action patterns. Triggers when: (1) about to say "should create", "need to fix", "I recommend" instead of acting, (2) end of work blocks before reporting completion, (3) reporting success while failures exist, (4) creating docs/plans without executing, (5) explaining fixes instead of implementing. Enforces ACT FIRST, DOCUMENT AFTER. Does NOT trigger for: genuine planning phases, user-requested documentation, or blocked situations requiring input.
