How is KUBB put together?

ShowNextAsk me aloud

One question at a time about your own work. Nothing is typed.

A month later

You built it. A month later you can’t explain it.

“How did you build it?” “Uh… Vercel?”

Three days on your site

Here’s what I saw.

  • 40times an hour you changed tool.
  • 20mina day, finished answers waited for you.
  • 1in 3prompts sent, and you were somewhere else within a minute.

What I do

One brick at a time.

  1. I remember how it was built.Every agent session of a project, folded into one memory.
  2. I hear what you keep telling your agents.Said twice, it is a rule you never wrote down.
  3. I hand your rules to every one of them.As a prompt, ready and not sent. You press Enter.

Guild rules

A mason keeps to the site.

  1. No screenshots.Events, not pixels. No keystroke log.
  2. No account.The memory stays on your Mac.
  3. Any model.Claude, one on your Mac, or none.
  4. You decide.A switch on what I read, send and keep.

Mason, his mark

Questions

Before you put me to work.

Free? What’s the catch?

None. I am open source under the MIT license, I need no account, and I run on your Mac. The man who built me takes coffee and commissions.

What do you read?

The app in front, the title of its window, the site of a browser tab, the prompt you are typing, and the logs your coding agents already keep. No screenshots and no keystroke log.

Does anything leave my Mac?

Only what you switch on, such as a question to your model. Settings lists what I read, what I send and what I keep, with a switch on each.

Which model do I need?

Any, or none. Your Claude login, one that runs on your Mac, or any other.

How do I get you?

Press Hire Mason. Today you build me from source, in four lines. A download you just open is on its way.

And Windows?

Windows are next. I am still on the walls.
