Phase 5: Implement

The Implement phase is where code gets written — but only after tests are written first.

What happens

1. Write the test — Create a failing test that defines the expected behavior
2. Watch it fail — Confirm the test actually fails (red)
3. Write implementation — Make the test pass with minimal code (green)
4. Refactor — Clean up without changing behavior
5. Commit — Atomic commit with clear message
6. Dispatch subagents — For independent tasks, spawn parallel agents

TDD discipline

HiveSpec enforces test-driven development. The agent must see the test fail before writing implementation code. This prevents false positives from tests that pass regardless of implementation.
