software-quality-assurance-analysts-and-testers Build features and full-stack apps using strict Test-Driven Development with agent teams, anti-cheat verification, and E2E browser testing. Always use this skill when the user wants to: build or implement something with tests, use TDD or test-driven development, implement a feature with "tests first" or "write tests before code", add test coverage to existing code, implement code against a failing test file, execute a multi-task implementation plan, build a full-stack app (backend + frontend), or invoke /tdd. Also use when the user mentions "red-green-refactor", "test-first", wants "no shortcuts" or "no cheating" in tests, asks to "resume" a TDD session, or wants comprehensive QA testing of their app. This skill handles everything from simple utilities to complex full-stack applications with React frontends and Express backends. Requires CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1.
