Codex works from instructions
You still need to explain what you want. The better the instruction, the better the result.
Beginner Training Resource
Codex for Beginners
A simple first step for teams moving from chatting with AI to delegating work. Start with clear communication, then connect the tools later.
What beginners need to know first
Think of Codex as an AI workspace where you can prepare real work faster, then review, improve, and approve it before anything goes out.
2
One task at a time
Beginners should avoid huge, vague requests. Start with one email, one summary, one workflow, or one decision.
3
You stay in control
The AI drafts, organizes, researches, and prepares. The human reviews, decides, and approves.
Get Codex running
Set up the desktop app first. The screen may look slightly different depending on your plan, device, and workspace settings.
1
Check access
Use the ChatGPT account your team wants to use for training. Codex is available on ChatGPT plans that include Codex.
2
Download the app
Go to the official OpenAI Codex page and download the desktop app for Mac or Windows.
3
Sign in
Open the app and sign in with the same ChatGPT account. If your company controls access, ask the workspace admin to enable Codex.
4
Start simple
Do not worry about advanced setup on day one. Start with one clear task and use the Role, Task, Goal, Questions framework.
5
Review before using
Codex can prepare work, but you still review, improve, and approve the final answer before anything is shared.
6
Keep this link
Use this page as your starter guide. Come back to the prompts whenever you need a clean way to ask Codex for help.
What Codex looks like
These are official OpenAI screenshots. Your app may look different as Codex updates, but the basic idea is the same.
Start with one instruction
Choose the workspace, describe the task, and let Codex begin preparing the work.
Projects and threads
Codex can organize work by project and keep multiple agent tasks separate.
Review before using
The AI prepares the work. You still review and approve the final output.
How teams use Codex together
Codex does not replace team collaboration. It helps each person prepare better work, then bring that work back to the team for review.
Separate tasks, shared standards
Team members can work on different tasks while using the same prompt framework, review rules, and workflow habits.
1
Each person starts privately
Each team member has their own Codex work. Other people do not automatically see their chat or Codex history.
2
Share the useful output
Share the final draft, summary, action plan, prompt, link, or workflow when it is useful for the team.
3
Review before using
Codex prepares the work. The team still checks facts, tone, context, and next steps before anything is sent or actioned.
4
Turn wins into workflows
When a prompt or process works well, save it so the whole team can reuse it instead of starting from scratch.
Normal chat mindset
- ×Ask one question and hope the answer is useful.
- ×Copy and paste information from every tool.
- ×Keep starting from scratch with no clear workflow.
- ×Use AI as a faster search box.
Agent workspace mindset
- ✓Delegate a specific piece of work with a clear outcome.
- ✓Let connected tools provide the source context when available.
- ✓Build repeatable workflows the team can reuse.
- ✓Use AI as an assistant that prepares work for review.
The four-part prompt framework
This is the first skill. Everything else becomes easier once the team learns to speak to AI clearly.
1
Role
Tell the AI who it should act as: assistant, operations manager, trainer, researcher, or client service manager.
2
Task
Tell the AI exactly what work it must do next. Keep the task specific.
3
Goal
Tell the AI what outcome you want. This helps it make better choices.
4
Questions
Tell the AI to ask before answering if it needs more context.
Example prompts
These prompts avoid copy and paste language. They prepare beginners for connected workflows without needing setup on day one.
Email Reply Prompt
Future State
From “paste this” to “go find this”
The breakthrough is simple: when the right tools are connected, AI can help from the places where work already happens. Email, calendar, team messages, and files become usable context instead of extra copy and paste.
Gmail
Calendar
Slack
Drive
Practice before the next training
The practice should produce real examples, not theory. Bring the actual prompts, outputs, and workflow ideas back to the next session.
Daily practice
Use the Role, Task, Goal, Questions framework once per working day. Save one good result and one bad result.
Tool inventory
List the tools you use every day: email, calendar, files, chat, CRM, project management, spreadsheets, and anything else.
Workflow inventory
Write down your top five daily tasks, top five weekly tasks, and the work that creates the most back and forth.
Agent idea
Complete this sentence: “I wish I could tell an AI agent to go find this, understand it, and prepare the next step for me.”
Bring proof
Bring one example where AI helped, one example where it failed, and one task you want to turn into a repeatable workflow.
Source basis: OpenAI describes Codex as an AI coding agent that can pair locally or run delegated work in the cloud, and the Codex app as a place for multiple agents, skills, automations, worktrees, and git functionality. OpenAI also documents ChatGPT apps and connectors for sources such as Gmail, Google Calendar, Slack, and Google Drive, subject to plan, region, permissions, and admin setup. In ChatGPT Business, each user has their own chat and Codex history, and teammates do not automatically see it.
