What is OpenAI Codex CLI

OpenAI Codex CLI is a lightweight coding agent that runs in your terminal.

Workflows & Knowledge Guides 🧠

A workflow is a tightly coupled set of Codex-native resources that facilitate specific projects

• AGENTS.md Practical Guide (Korean) by soul-sol - Korean guide to Codex instruction discovery, nested overrides, repository boundaries, completion criteria, and ready-to-use single-service, monorepo, and library examples.
• oh-my-codex - OmX - Oh My codeX: Your codex is not alone. Add hooks, agent teams, HUDs, and so much more.
• Nika by Thibaut Melen - Codex plugin for Nika workflows: /nika:check, /nika:explain, /nika:new + authoring skill + read-only MCP oracle — audit .nika.yaml DAGs (schema, permits, honest cost floor) before a single token is spent.

Tools

GUI & MCP

• MCP Linker - GUI for managing MCP configs for Codex CLI.
• x-twitter-scraper - X/Twitter data extraction skill & MCP server for AI coding agents. 20 tools: followers, tweets, replies, mentions, lists, hashtags, spaces & more.
• Codex Skins - One-click wallpaper/theme gallery for the OpenAI Codex desktop app. Reversible full-window CDP theme injection, macOS/Windows. Open-source engine (MIT).

MCP server

• GBrain - Persistent brain layer for Codex CLI: synthesis, graph traversal, and gap analysis over your own corpus, so the agent stops being amnesiac about everything that is not code. codex plugin marketplace add garrytan/gbrain@codex-plugin; PGLite, no server.
• Ouroboros - Agent OS for repeatable AI coding workflows. It turns vague goals into executable Seeds through an interview, then runs staged, budgeted evaluation loops with Codex CLI or 12 other runtimes.
• prompt-to-asset - MCP server that generates app icons, favicons, OG images, logos, and wordmarks by routing requests across 30+ image generation models. Zero API key needed on first run via free-tier providers.
• click-to-mcp - Auto-wrap any Python Click/Typer CLI as an MCP server. Zero-code transformation that introspects CLI commands and exposes them as MCP tools. Works with Codex CLI, Claude Code, and any MCP client. pip install click-to-mcp
• claude-codex-bridge - Bidirectional MCP bridge for Codex CLI and Claude Code collaboration, with persistent Claude sessions and shared collaboration files.
• AccInt - Local-first MCP work memory for Codex CLI, Claude Code, OpenCode, and Cursor with scored retrieval, commitment tracking, and outcome-based credit across sessions.
• Agent QA - The self-improving QA agent for software teams. Run agent-qa mcp to let Codex author and execute natural-language web/mobile tests, inspect artifacts, triage failures, and guide fixes with persistent test memory.
• Vestige - Local-first cognitive memory MCP server that gives Codex CLI persistent recall across sessions. SQLite storage, FSRS-6 retention with active forgetting so old context decays instead of piling up, prediction-error gating, and hybrid retrieval. Single Rust binary, npm install -g vestige-mcp-server.
• GoodMemory - Local-first, auditable memory for Codex CLI and Claude Code. goodmemory setup installs scoped recall hooks and read-only MCP inspection; SQLite persistence is the default, while optional writeback stays reviewable and reversible.

setup tool

• codex-1up - Equips your Codex CLI coding agent with powerful tools.
• codex-universal - Base Docker image used in Codex environments.

Session manager

• crystal - Run multiple Codex and Claude Code AI sessions in parallel Git worktrees. Test, compare approaches & manage AI-assisted development workflows in one desktop app.
• Parallel Code - Desktop app for running Codex CLI, Claude Code, and Gemini CLI agents side by side in separate Git worktrees.
• vibe-kanban - Kanban board to manage your AI coding agents.
• ccmanager - Coding Agent Session Manager that supports Claude Code / Gemini CLI / Codex CLI / Cursor Agent / Copilot CLI.
• codmate - A macOS SwiftUI app for managing CLI AI sessions.
• agent-sessions - Local-first macOS app for browsing and full-text searching Codex session history alongside other local coding-agent transcripts; resume is available where the underlying CLI supports it.
• cctop - Keyboard-first macOS menubar monitor for Codex CLI sessions. Shows which runs are working, waiting, or need approval, jumps back to the exact terminal pane, and also supports Codex Desktop, Claude Code, opencode, and pi.
• agentbox - Run multiple Codex (and Claude Code / OpenCode) sessions in parallel, each in its own sandboxed box — local Docker or cloud VMs (Hetzner/Daytona/Vercel/E2B). Sub-1s checkpoint starts, per-box browser + VS Code, and a dashboard to switch between boxes.
• Orca - Desktop IDE that runs Codex CLI and other agents (Claude Code, Cursor, Gemini) in parallel, each in its own Git worktree, with built-in terminal and diff review.
• GraphCode - macOS app that arranges Codex, Claude Code, and Copilot CLI sessions into a graph. Each node is a live terminal you can attach to mid-run; each edge is a hand-off, message, or spawn that fires while you're away. Sessions survive app quits and reboots.

Account switcher

• codex-account - Switch between multiple Codex accounts without signing out — never revokes tokens, keeps every account signed in, and syncs refreshed tokens back into saved profiles. Single-file bash script.

WebUI & App

• happy - Mobile and Web client for Codex and Claude Code, with real-time voice and encryption.
• CodexMonitor - An app to monitor the Codex situation.
• CodexFlow - An enhanced GUI tool designed for
