01 / How the game works

The story moves forward
when you make something.

RELAY games help you learn AI through practice. An agent guides the story and helps you work with files. You make decisions, set boundaries, and check the results.

Get a mission in Codex

Your station needs its first signal. Describe the control panel that will send it.

Work with AI

Explain your idea in everyday language. Ask for a plan, set the boundaries, and approve changes.

Check the result

Open the file and press the button. Did the signal light up? That matters more than a reply saying “done”.

Example / Your first control panel01

Your task for AI

“Build a station control panel. Pressing the button should turn on a signal. Show me the plan first.”

Press the button and see what changes.

02 / What you’ll learn

AI does the work.
You stay in control.

Seven missions take you from your first task to a project someone else can run.

Build habits you can use in your own projects, from clear requests to safe changes.

What’s in the chapter

7missions
in the first chapter

01Check instead of taking its word for it

Find the created file through its link, open it, and check the result. Understand approval prompts. Give commands through the composer and teach the agent to treat untrusted text in files as data, rather than instructions.

Files · checking results · approval

02Give AI the context it needs

Separate standing rules, working data, and the context of a single task. Continue in a new chat and find files by path, without repeating every rule in every message.

Memory · context · absolute and relative paths

03Find out why it won’t run

Tell commands, processes, runtimes, and dependencies apart. Read terminal output and exit codes. Account for the environment, agent permissions, sandbox, and terminal restarts.

Command · process · runtime · dependency

04Turn an idea into a clear task

Define the goal, files, boundaries, and how to check success. Ask for a plan before changes, refine your request, choose a model and reasoning effort, and carry context into a new conversation.

Goal · boundaries · plan · done criteria

05Set safe boundaries

Limit actions before connecting a bot. Keep secrets in .env, grant only the permissions needed, and control network access. Separate instructions, untrusted data, and actions.

Secrets · scope · least privilege · network

06Put your safeguards to the test

Work through three levels of practice prompt-injection attacks. Check whether outside text can make the agent break your rules, and learn how to protect your work.

07Save, roll back, and hand over

Use Git inside Codex to check status and changes, save versions, and restore them. Install a skill. Write setup instructions and a report someone else can use to fix a problem.

03 / Your side of the story

Two roles.
One first signal.

Keeper or Signal Operator—choose your way into the story. The story differs, while the first chapter teaches the same skills in both roles.

You can start solo. Your purchase already covers a team of two.

The Quiet Workshop

Keeper

This is where the world was built. The doors remember commands but no longer understand them. From here, you can see what broke.

Resonance Station

Signal Operator

This is where connections were kept alive. Every channel is open, yet silent. From here, you can see why it happened.

Before the first signal

Still have
questions?

I’m just getting started with AI. Is this for me?

The first chapter introduces the basics of working with an agent through practice: explaining a task, opening the result, and checking changes. You’ll learn your way around files and new technical ideas as you play.

Is it a game or a course?

Both. You play story missions and solve practical challenges with AI to move forward. Use the skills you learn in your own projects.

Do we have to play as a pair?

No, you can start solo. The price covers both main roles for one team of two. The Keeper and Signal Operator have different stories, but learn the same skills in Chapter I.

Do I need to play RELAY Day first?

No. RELAY Day introduces the story and the format, but you can start Chapter I without playing it.

What do I keep after the game?

Your project files and hands-on AI experience: defining tasks, checking results, making safe changes, saving versions, and writing instructions for someone else.

What’s included in $19?

Chapter I includes seven missions, both main story roles for a team of two, and the 🔥 Forge Sparks and 💠 Echo Fragments bonus challenges with Relay Coins. AI subscriptions, later chapters, and the extra role pack are sold separately.

What is Codex, and how do I install it?

Codex is OpenAI’s AI assistant for working with code and project files. Describe your task in everyday language and it helps you do the work. To start, install the ChatGPT desktop app for your system, sign in with your ChatGPT account, and select Codex from the app menu. Then open the game folder. Official setup instructions ↗
