Key Concepts

What is Spec-Driven Development?

Spec-Driven Development (SDD) is a methodology where you and your AI coding assistant agree on what to build before any code is written. OpenSpec implements this through:

• Proposals - Structured change requests with technical designs
• Specifications - Living documentation that captures functional requirements
• Task Checklists - Implementation tasks with AI guidance
• Archives - Completed changes preserved for reference

Core Workflow

/opsx:new → /opsx:ff or /opsx:continue → /opsx:apply → /opsx:verify → /opsx:archive

Why OpenSpec?

• Universal - Works with 30+ AI coding assistants
• Open Source - MIT licensed, no vendor lock-in
• No API Keys - Runs locally without external dependencies
• Brownfield-First - Designed for mature codebases, not just greenfield projects
• Persistent Context - Specs live in your repo alongside code
