Overview
A habit helps one engineer. A process helps the whole team.
Extend Codex Workflows is a free, self-paced 90-minute course for software engineers in OpenAI Academy’s Codex pathway. It shows how to turn effective ways of using Codex into repeatable team processes, with oversight kept in the loop. It is the middle Codex pathway course, and OpenAI says its badge is not a certification.

Learn all the way down.
Learn all the way down.
Perform when it matters.
Make it repeatable
Turn those habits into a process another engineer can follow and get a similar result.
Share it with a team
Roll the process out across a team, so Codex use is consistent instead of personal.
Keep oversight in
Build review and human oversight into the process, so speed does not replace judgment.
Course outline
From a Codex habit that works
From a Codex habit that works
to a process your team repeats.
We design this course ourselves. OpenAI issues the credential, and LUNARTECH is independent of OpenAI.
Most engineers settle into habits without testing them. You keep a log of tasks, prompts and results, compare the runs that went well with those that did not, and find what made the difference.
- Logging tasks, prompts and outcomes
- Comparing good runs with poor ones
- Separating luck from method
- Naming the habits behind your best results
- Measuring review time and rework
You build A short log of real Codex tasks with the habits that made them work.
A habit becomes a process once someone else can follow it. You turn what works into task templates, prompt patterns and repository guidance, each with an example of a good result.
- Turning a habit into numbered steps
- Task templates for common change types
- Prompt patterns with worked examples
- Defining done for each kind of task
- Recording known failure modes and fixes
You build A Codex playbook with templates for three common kinds of task.
A repeatable process gives similar results for different people. You test your playbook on a colleague’s task, find where it leaves room for guesswork, and tighten the inputs, checks and finish criteria.
- Handing the playbook to someone who did not write it
- Finding the steps that vary by person
- Standard inputs and standard checks
- Automating checks that run every time
- Versioning the playbook as it improves
You build A playbook revised after a colleague ran it on a real task.
Shared practice needs more than a document. You plan how a team adopts the process: where the guidance lives, how new members learn it, and how people report what works and what does not.
- Putting shared guidance in the repository
- Onboarding engineers to the process
- Agreeing team conventions for prompts and tasks
- Collecting feedback after each use
- Keeping the playbook current as the team learns
You build A rollout plan for one team, with owners and a feedback routine.
Faster changes still need accountable people. You build review gates into the process, decide who owns each Codex-made change, and keep a record that shows what was generated, checked and approved.
- Setting review gates by risk
- Assigning an owner to every change
- Keeping the reviewer independent of the prompt
- Recording what was generated and approved
- Noticing when speed is replacing judgment
You build Oversight rules and a review checklist built into your team’s process.

Reviews
Real stories from the community.
LUNARTECH Academy has been the most empowering learning experience of my life, giving me a clear, structured path from the absolute basics to building real-world AI systems with confidence.
Your page is fantastic. As a bachelor’s student in Data Science now accepted for a master’s at UConn, your work has been a real source of motivation.
The programme’s clear, bite-sized content and practical projects dramatically improved my speed from fuzzy idea to MVP and my ability to communicate AI value. I followed the system, and it works.
I really appreciate your teaching style and the way you break down complex topics. It has been incredibly helpful.
After years working mainly with R for econometrics, I found your Python machine learning course a refreshing and engaging way to learn Python.
As a Data Science graduate, I want to thank you for the effort you put into making videos to support growing data scientists.
I’ve been following your work since taking your machine learning course, and I’m impressed by your practical approach to applying AI.
