# SDD (Spec-Driven Development)

## Definition

Spec-Driven Development is the discipline CoreStory extends into **Spec-Driven Operations**: specs drive workflows, workflows drive infrastructure/runtime orchestration, agents execute against governed context, and operational state feeds back into the semantic layer.

## Key properties

- Bounded knowledge domain: audience = product, engineering, AI agents, implementation workflows

- Contains: specs, workflow semantics, execution contracts, implementation lifecycle, validation semantics

- Classification: hybrid public/internal

- Extends beyond classic SDD toward operations: infra/runtime orchestration driven by specs
