Spec Kit: Specification-Driven Development
Overview
Spec Kit implements Specification-Driven Development (SDD) - a methodology where specifications drive code, not vice versa. Instead of specs serving as documentation for code, code becomes the expression of specifications.
The Power Inversion
Traditional development: Code is truth, specs are scaffolding SDD: Specifications are truth, code is generated output
This eliminates the gap between intent and implementation by making specifications executable through AI.
Commands
/speckit.specify <feature-description>
Creates a comprehensive feature specification from a natural language description.
