OpenSpec

OpenSpec is a CLI tool that manages the SDD workflow — creating changes, scaffolding artefacts, tracking progress, and archiving completed work. It provides the structure that turns spec-driven development from a discipline into a habit.

The artefact pipeline is the key. Proposal, specs, design, tasks — each unlocks the next, each builds on the previous. The CLI tracks what's done and what's ready. AI agents read the artefacts for context and implement against them. The result is traceable, reviewable change management that works with AI-assisted development rather than against it.
