About

OpenSpec is an open-source spec-driven development framework designed to bring structure and clarity to AI-assisted coding workflows. It introduces a lightweight specification layer that helps teams define requirements before writing code. The platform organizes each change into structured artifacts such as proposals, specifications, designs, and task lists. It integrates with over 20 AI coding tools, allowing developers to use their preferred assistants while maintaining consistency. OpenSpec emphasizes an iterative and flexible approach rather than rigid development phases. Its command-based workflow enables users to propose, implement, and archive features efficiently. Overall, OpenSpec helps developers align with AI systems, reduce ambiguity, and produce more predictable and reliable outcomes.

About

oh-my-codex, also known as OMX, is a workflow layer for OpenAI Codex CLI that helps users start stronger coding sessions and manage complex development work with more structure. The tool keeps Codex as the execution engine while adding prompts, skills, hooks, runtime support, HUDs, agent teams, and durable project state. OMX supports a recommended workflow built around deep interviews, planning, goal creation, execution, verification, and long-running task management. It stores project guidance, plans, logs, memory, and runtime state in a dedicated .omx folder so work can stay organized across sessions. The platform is primarily designed for macOS and Linux users working with Codex CLI, with additional support for team workflows through tmux. oh-my-codex helps developers use Codex more effectively by adding repeatable processes, stronger task routing, and better runtime coordination.
