#1 Introduction & Setup

Learn how to set up OpenAI Codex from scratch — install Node.js, generate your API key, configure environment variables, and install the Codex CLI tool.

#2 Running Cloud Tasks

Discover how to execute Codex tasks in secure cloud containers — offload builds, tests, and heavy operations without slowing down your local machine.

#3 Automated Code Review

Use Codex to automatically review your staged changes for security vulnerabilities, performance bottlenecks, and code style violations.

#4 Using the Codex CLI

Master the Codex CLI — from initializing your workspace and interactive chat to one-off commands and piping data for instant analysis.

#5 CLI Commands & Resuming Sessions

Learn how to manage Codex sessions — list past sessions, resume interrupted work, use dry-run mode for safe testing, and select models for different tasks.

#6 Using the AGENTS.md file

Learn how to create and maintain an AGENTS.md file — the configuration that keeps Codex aligned with your project's frameworks, coding standards, and architectural patterns.

#7 Codex IDE Extension

Install and use the Codex IDE extension — ghost text predictions, inline chat for modifying code, and sidebar communication with full workspace context.

#8 Context, Reasoning & TODO's

Understand how Codex gathers context, plans with chain-of-thought reasoning, creates implementation plans, and tracks progress through task checklists.

#9 MCP Servers

Learn about the Model Context Protocol (MCP) — connect Codex to GitHub, databases, and external APIs through secure, configurable server integrations.

#10 Delegating Tasks to the Cloud

Use Codex as a project manager — give it a large objective and watch it break the work into sub-tasks, dispatch them to cloud agents, and assemble the results.

#11 Running Tasks in Parallel

Learn how to batch-process multiple files simultaneously — parallel workers, branch isolation, and intelligent auto-merging for rapid codebase transformations.
