This generates failing tests for the TDD red phase, the part where you write tests before implementation. It uses a test-automator agent to create comprehensive test suites with proper Arrange-Act-Assert patterns, edge case coverage, and framework-specific setup for Jest, pytest, Go, RSpec, and others. The tests are designed to fail for the right reasons (missing behavior, not syntax errors) and include things like boundary conditions, null handling, and error scenarios. Honestly, the real value is in the structured approach to edge cases and the anti-pattern warnings, since writing good failing tests is harder than it sounds. It won't run tests against production and expects you to verify the failures locally before moving to the green phase.
