OpenSpec is a lightweight, configurable CLI framework for creating and managing software specifications driven by AI coding assistants. It lets teams capture requirements, iterate on designs, and coordinate implementation through chat-driven workflows.

Use cases

• Create and iterate on project specifications using an AI assistant.
• Generate implementation checklists and task lists from high‑level ideas.
• Synchronize requirements, design, and code changes across a team with AI guidance.
• Automate the proposal, review, and application of feature specs in a chat interface.
• Maintain a living spec repository that stays in sync with code as development progresses.

When to choose

• You want a spec‑first workflow that integrates directly with AI coding tools like Claude, Cursor, or GitHub Copilot.
• Your team needs a lightweight, language‑agnostic way to capture requirements and generate actionable tasks without a heavyweight requirements management system.
• You prefer a CLI that can be scripted and run in CI/CD pipelines while still supporting interactive chat commands.

When to avoid

• You require formal, standards‑based specifications such as full OpenAPI or UML diagrams.
• Your project does not involve AI assistants or you prefer manual specification processes.
• You need deep integration with non‑Node.js ecosystems that cannot run the OpenSpec CLI.
