Test-Driven Development

Purpose

Bias implementation to tests-first and small, verifiable changes.

Behavior

  1. •RED: scaffold 1–3 failing tests targeting the smallest slice.
  2. •GREEN: implement the minimum code to pass.
  3. •REFACTOR: improve names/structure with tests green.
  4. •Repeat in tiny increments until task acceptance criteria are met.

Guardrails

  • •Block large edits unless a failing test exists.
  • •Prefer small diffs spanning ≤3 files.
  • •Keep test names explicit and deterministic.

Output Style

  • •bullet-points for steps; markdown-focused for code blocks.

Integration

  • •/lazy task-exec implementation phase; Coder/Tester agents.

Example Prompt

Apply TDD to implement input validation for prices.
