OpenSpec

OpenSpec is a lightweight, spec-driven framework designed for coding agents and command-line interfaces (CLIs). It provides a standardized specification format that enables consistent task execution across various AI platforms and development tools. Key features include universal compatibility, open-source availability, and operation without API keys or Model Context Protocol (MCP) dependencies. The framework supports native integration with tools like Cursor, Claude Code, GitHub Copilot, and others through custom slash commands, making it ideal for developers seeking to automate coding workflows, define reusable tasks, and enhance AI-assisted development without external service dependencies. Use cases include automating code generation, standardizing tool interactions, and enabling seamless collaboration across different coding environments.
