Test-driven development structures feature implementation through RED-GREEN-REFACTOR cycles: write failing tests first, implement code to pass them, then refactor for quality. This approach ensures robust code and catches bugs early by validating requirements before writing production code.

Task decomposition structures complex features into phases, from initial design through incremental implementation, testing, and integration. This multi-phase delivery approach reduces risk, enables parallel work, and ensures each component meets quality standards before final handoff.

Enforce code quality through linting, formatting, and conventional commit messages at each phase. Combined with unit and integration testing, this maintains consistent codebases and prevents regressions across incremental commits and collaborative Git workflows.

Yes. TDD workflows apply directly to architectural specifications by translating designs into failing tests, then implementing code that satisfies both the spec and test requirements. This ensures implementation aligns with intended architecture while maintaining quality standards.

Feature implementation includes both unit tests—validating individual functions and classes—and integration tests—verifying components work together correctly. Combined with linting and documentation updates, this comprehensive testing ensures production-grade quality before deployment.
