wtf is codex_workflows?

This repository provides a custom workflow package for Codex, which appears to be an AI coding assistant. The workflow adds project-specific guidance, task routing, and specialized subagents to help manage long development plans across multiple sessions. It is designed to conserve tokens, making it suitable for users on ChatGPT Plus plans with usage limits. Installation is straightforward. You download a ZIP file, place it in your project's root directory, and ask the Codex assistant to extract and install it by reading an included setup guide. The workflow only applies to the current project, so you must repeat the process for each new project you start. After installation, Codex asks configuration questions about your design principles, such as preferring modular code, keeping dependencies low, or always running tests after changes. The workflow offers three task routes. The Light route is the default for simple tasks and uses minimal context. The Medium route lets the main Codex agent handle work directly, which can be faster and cheaper than coordinating subagents for moderately complex tasks. The Heavy route is for large plans where a main agent coordinates multiple worker subagents. You switch routes by telling Codex which one to use in your prompt, and the choice stays active for the rest of the session. A key feature is the End-of-Session handoff. When you finish working, you tell Codex to end the session. It then cleans up, updates documents, and commits changes so you can resume the project later without losing context. Users can customize this handoff process and add their own subagents to extend the workflow further. The README provides clear installation and usage instructions but assumes prior familiarity with Codex and its agent system.
