What is AI TDD and how does it work?

AI TDD applies Test-Driven Development to guide AI: write one failing test (red), minimal code to pass (green), refactor, repeat. Use guidelines file for consistency.

Does TDD with AI really reduce PR sizes?

Yes — forces bite-sized changes. Original team saw massive PRs shrink, reviews speed up.

Can I use this with any AI like GPT or Claude?

Absolutely. Guidelines and context files make it model-agnostic. Start with Claude for best refactor prompts.
