TDD

Value: Feedback -- short cycles with verifiable evidence keep AI-generated code honest and the human in control. Tests express intent; evidence confirms progress.

Purpose

Teaches a five-step TDD cycle (RED, DOMAIN, GREEN, DOMAIN, COMMIT) that adapts to whatever harness runs it. Detects available delegation primitives and routes to guided mode (human drives each phase) or automated mode (system orchestrates phases). Prevents primitive obsession, skipped reviews, and untested complexity regardless of mode.

Practices

The Five-Step Cycle

Every feature is built by repeating: RED -> DOMAIN -> GREEN -> DOMAIN -> COMMIT.
