Specification-driven development (SDD) is a process discipline that requires writing validated specifications before code. It prevents code-spec drift, maintains quality through mandatory workflows, and makes specs the single source of truth for all development decisions.

State your goal to the skill, which automatically routes you through the correct SDD stage: brainstorm, spec creation, implementation, evolution, or verification. The skill acts as your project manager, ensuring you follow the mandatory workflow and use the right tools for each phase.

No. SDD enforces a mandatory spec-first protocol where no code is written without a validated specification. The skill prevents shortcuts by routing all development tasks through the appropriate workflow stage first.

The skill automatically discovers and invokes the correct SDD skill for your task, maintaining seamless integration with spec-kit for automatic setup and validation. It coordinates the full workflow from brainstorm through verification.

SDD's rigorous workflow and mandatory verification stages prevent code-spec drift by treating specifications as the single source of truth. The skill enforces validation at each stage to catch misalignment early.

Yes. The skill includes an evolve workflow stage for modifying existing features. It ensures that updates to code are reflected in updated specifications, maintaining spec compliance throughout the feature lifecycle.
