Devplan

Devplan is an open-source tool designed to transform project ideas into detailed, agent-executable development plans tailored for AI coding agents. Serving both as a Model Context Protocol (MCP) server and a standalone skill/plugin, it brings structure, validation, and reliability to AI-powered coding projects by creating thorough implementation plans, managing task progress, integrating lessons learned, and embedding agent workflows directly into development processes. It is ideal for developers, teams, and organizations seeking reliable, repeatable, and validated AI-assisted software development.
