Every Friday there is another one. The whole series is on YouTube, and the files themselves are at gmcarl.xyz/skills.

A lab for builders, founders and technologists. One hour, online, small. Bring one job you already do by hand, and leave with a skill file your agent loads and follows. However early you are, you do not need a senior title, a team, or a budget.

Small on purpose, so everyone gets looked at. The first one is free. Save a seat and bring the job you want to hand off.

What you need

A laptopYou will be typing. A phone will not do it.
An AI agent you can talk toClaude Code, Cursor, Codex, ChatGPT or Copilot. A free plan is fine. Have it open before we start.
One job you do by handSomething you have done three times already. Write it in one sentence before you arrive.
Somewhere to save a text fileThat is all a skill file is.

What you do not need: a senior title, a team, a company account, or any experience writing these. If you have shipped anything at all, you are the person this is for. New to an agent entirely? Take the free intro lab first.

How a lab runs

I doI take one job from the room and build its skill file live, saying every decision out loud.
We doThe room takes the next one and calls every change. I only type what you say.
You doYou build yours on your own machine, then say its trigger and watch your agent pick it up.

A skill file is a plain text file: the steps you would follow, the checks that catch it when it goes wrong, and one line that tells your agent when to load it. It is not a prompt you retype. This is how GM! Carl runs: nineteen of them make the shorts, the lessons, the captions and the calendar. The files are public at gmcarl.xyz/skills.

The labs

The free oneYou watch one job get built, then start your own. Any number of people.
The paid oneYour job gets built, run and fixed while you watch. Small room, so everyone gets looked at, and the theme comes from what the room sent in.
The first one is free. After that: first Wednesday of the month free, third Wednesday the lab. Always 6:00 pm Central. Always one hour. Small enough that everyone gets looked at.

Every date is confirmed by email a week ahead. Paid labs have a reduced seat for students and people between jobs, no proof needed: ask and I will send it. No list-selling, no drip, and you can reply "stop" any time. The free intro is the session I take on the road, most recently MeasureCamp Chicago. Season 0 at Haven Cafe: gmcarl.xyz/season0.
