Test-First TDD Workflow FAQs

Question 1

How does 'Red-Green-Refactor' work in this skill?

Accepted Answer

The skill guides you to write a failing test (Red), implement the minimum code necessary to make it pass (Green), and then clean up the code while keeping tests passing (Refactor).

Question 2

Can I use this skill for existing projects?

Accepted Answer

Absolutely. It is highly effective for adding new features or fixing bugs in legacy codebases by establishing a test-driven boundary for all new changes.

Question 3

Does it support all programming languages?

Accepted Answer

Yes. While the skill provides TypeScript examples, the core TDD principles and workflow logic are language-agnostic and apply to any development environment supported by Claude Code.

Question 4

What is the 'Iron Law' enforced by this skill?

Accepted Answer

The Iron Law dictates that no production code can be written without a failing test existing first. Any code written before a test must be deleted to ensure the test actually verifies the intended behavior.

Question 5

When is it acceptable to skip the TDD workflow?

Accepted Answer

Exceptions are generally limited to throwaway prototypes, purely generated code, or simple configuration files, and typically require explicit confirmation from the human partner.
