# spec-dd
Specification-driven development workflow skill. Orchestrates a spec-first discipline: frame a one-page Product Spec (problem, falsifiable bet, success criteria, evaluation) that replaces the PRD, then write behavioral specifications, derive test scenarios, plan implementation, and verify alignment across all artifacts and code. Acts as a workflow navigator with advisory quality gates between phases.

Specification-driven development workflow skill.

Acts as a workflow navigator with advisory quality gates between phases.
