Overview

OpenSpec is a spec-driven development (SDD) framework for AI coding assistants that enables teams to plan, document, and implement features through structured Markdown specifications. Its core value proposition is providing a lightweight, iterative workflow where AI agents generate specs and tasks before writing code, ensuring alignment and reducing drift.

Installation

npm install @fission-ai/openspec

Problem solved

OpenSpec solves the problem of AI agents generating code without proper context or planning, leading to misaligned or incomplete implementations. Unlike ad-hoc prompting, it enforces a spec-first workflow where requirements, design, and tasks are documented and reviewed before coding, making it suitable for brownfield projects and team collaboration.

What you can build

Developers can build features end-to-end with AI assistance, from exploration and proposal to implementation and archiving. Real-world use cases include adding dark mode, cross-repo features, and shared requirements across teams. The ceiling includes managing complex, multi-repo projects with a single source of truth for specs and changes.

Bottom line

OpenSpec is ideal for developers and teams using AI coding assistants who want structured, reviewable planning before code generation. It's less suited for rapid prototyping or solo developers who prefer minimal overhead. The key trade-off is upfront spec effort versus reduced rework and improved alignment.
