What Spectastic.Spec does
description: Write a feature specification — what to build, for whom, and how success is measured. Use when starting a new feature, specifying requirements and success criteria, or capturing what a feature must do before designing the implementation — not project-wide rules (/spectastic.principles), the how (/spectastic.design), or throwaway learning (/spectastic.explore). argument-hint: triggers:
- "write a spec for a feature"
- "specify what to bu
