A new coworker is competent. One that’s been working for you for three months is genuinely useful. The difference isn’t the model — it’s everything it has picked up about you.

The three things that accumulate

Memory

Notes about you, your preferences, and the work. Built from corrections you make in passing.

Skills

Procedures worth repeating — written by you, or proposed by your coworker and approved by you.

Instructions

The standing brief, which you tighten as you learn what it gets wrong.
None of it happens behind your back. Every proposed change waits on the Improvements tab for your yes.

A proposal, with exactly what approving would do spelled out underneath it.

Your part in it

The single highest-return habit: correct it in the chat, in plain words, in the moment.
“Too long — half that next time.” “Always check the date on a pricing page before you quote it.” “Don’t use that source, it’s unreliable.”
Each of those is a sentence you’d say to a colleague, and each one lands as something your coworker keeps. This is why it improves — not from watching you, but from you telling it.
The third correction is the signal. Say something once, it’s a note. Say it three times and it should be a skill or a line in the instructions.

What your coworker does on its own

It notices patterns in its own work and proposes changes: a new skill for a procedure that worked well, a fix to one that didn’t, a note worth keeping. You approve, tweak or dismiss each one. Tweaking is underrated — a proposal is a decent first draft, and five minutes tightening it turns it into something that actually gets used. There’s also an optional periodic tidy-up of the skills it has written for itself, off by default. See Skills that improve themselves.

What a month looks like

1

Week one — you correct a lot

Format, tone, which sources it trusts, how much detail you want. This feels like work. It is, and it’s the whole investment.
2

Week two — patterns emerge

You notice you’ve said the same thing three times. Write the skill.
3

Week three — proposals start being good

Its suggestions on the Improvements tab start matching what you’d have written.
4

Week four — you stop thinking about it

The output arrives in your format, with your standards applied, and you check rather than fix.

Good to know

Improvement belongs to one coworker. Three coworkers each learn their own job. Save a well-tuned one as a template to give a new hire the same starting point — skills and instructions carry, memory doesn’t.
A coworker that isn’t getting better is usually one nobody corrects. If the output is consistently almost-right and nobody says so, nothing changes.

Common questions

No. Every change to its skills, memory or instructions waits for your approval on the Improvements tab.
Every couple of weeks. Proposals accumulate harmlessly, and reviewing a few at once is easier than one at a time.
A sentence in the chat costs nothing and saves the same correction every task afterwards. It’s the highest-return thing you can do.
Models improve, and you can switch to a newer one at any time. What’s yours — the skills, memory and instructions — carries across.
Open the Memory tab and delete the note, or edit the skill. Everything it learned is visible and editable.
