Test-driven development with task breakdown translates feature design into structured tasks using Red-Green-Refactor cycles. Break requirements into testable steps, write failing tests first, implement code to pass them, then refactor. Track progress in a tasks.md file mapped to acceptance criteria for full traceability.

Establish quality gates using tests, linting, and code reviews as guardrails before progressing tasks. Each task must pass its test suite and lint checks before advancing to the next phase, ensuring disciplined execution and preventing regressions during feature implementation.

Map each implementation task to specific requirements and acceptance criteria in your tasks.md documentation. This traceability artifact links design specifications to code execution, enabling you to verify every requirement is tested and implemented before marking a task complete.

Spec-driven implementation applies across development projects of varying scope. The two-phase workflow—task breakdown followed by Red-Green-Refactor execution—adapts to any feature size, from small enhancements to complex system changes, as long as you document tasks and acceptance criteria upfront.

Task breakdown organizes what needs doing; test-driven development ensures each step is proven correct. Together they create disciplined execution: tasks provide the roadmap, tests validate each implementation step, and refactoring keeps code clean throughout the workflow.
