#119 Robin: 18 Codex Concepts That Turn It Into Your Personal AI Operating System

Codex can research, manage files, build websites, browse the web, run scheduled tasks, and even delegate work to other AI agents — without requiring you to know how to code.

The hard part is understanding how all the pieces fit together. This episode breaks Codex down into 18 essential concepts, from Projects and AGENTS.md to Skills, Subagents, Sites, Scheduled Tasks, and Voice Mode. Pasted markdown

We’ll talk about:

• Projects + AGENTS.md: How to give Codex long-term context and clear rules for how it should work.
• The Agent Loop: How Codex plans, uses tools, checks results, and keeps going until the task is done.
• Skills and Plugins: How to turn repeated workflows into reusable systems and connect apps like Gmail, Drive, GitHub, and more.
• Subagents: How Codex can split research and larger tasks across multiple AI agents working in parallel. Pasted markdown
• Scheduled Tasks + Voice: How to make Codex work automatically and control complex workflows without constantly typing. Pasted markdown
