Implement features from task specifications or user stories using Test-Driven Development (TDD). This skill writes tests first, implements code to make tests pass, and validates the implementation meets all acceptance criteria.

Core Principles:

• Test-Driven Development (Red → Green → Refactor)
• Deterministic operations via bmad-commands
• Automated acceptance criteria verification
• Continuous validation

Prerequisites

• Task specification exists at workspace/tasks/{task_id}.md
• bmad-commands skill available at .claude/skills/bmad-commands/
• Development environment configured
• Test framework installed (Jest or Pytest)
