The TWIMCO notebook

Field notes.

Useful observations from inside the work.
For people building a better way.

Opening note / AI & judgment

Let AI draft your review replies. Read the angry ones yourself.

Replying to every review takes time nobody has, and plenty of tools now offer to do it for you. For the five-star thank-yous, that's fine. For the customer describing a bad evening in detail, a smooth automatic reply can make things worse in public.

Editorial engraving of a sunny florist's workroom where the owner with an order pad points from a tablet showing a soft shaded band to a nearly empty bucket of tulips, as her assistant holds a bucket of eucalyptus and a driver wheels in fresh flowers.

A forecast that gives you one number is hiding the useful part.

"Can the AI just tell me how much to order?" It's the question we hear most from owners looking at demand forecasting. Here's roughly how the conversation goes, and why the answer we give is about ranges, sold-out days and who makes the call.

Editorial engraving of a bright meeting nook where an account manager highlights one passage on a long ribbon of printed transcript beside a laptop showing a short summary, as a colleague with a headset leans in to point at it.

The AI summary dropped the one thing the customer said twice.

"Customer happy, wants to renew, send quote." It reads well, it's mostly true, and it leaves out the condition the whole renewal depends on. Reading one call against its summary, line by line, shows what to ask these tools for and what a person still has to check.

In a sunlit clinic consultation room, a nurse practitioner in a sage cardigan holds a terracotta pen over a printed page she is marking up, an open laptop beside her and an unsealed envelope waiting on the desk, while an older man and his adult granddaughter sit across from her and listen.

Anthropic's human-review rule isn't new. Now it's spelled out.

If your Claude-powered screener tells someone they don't qualify, a qualified person was always supposed to see that first. Anthropic's October 8 rewrite makes the rule much harder to miss.

Editorial engraving of a bright office kitchen where four colleagues of different ages stand at a counter sorting blank cards into green, ochre and terracotta folders and a small locked tin, with a phone and laptop among them.

Your team already uses AI. Write the policy for that team.

If the policy says no AI and people are pasting customer emails into a chatbot on their phones, the policy isn't working. These are the questions worth answering before you write one more rule.

Editorial illustration for Field Note: An override without a reason is a silent decision.

An override without a reason is a silent decision.

A person disagrees with the agent, edits the value and moves on. Now the record shows only the final answer, and later nobody can tell judgment from a glitch. When someone overrides an automation, the original and the reason should both stay.

Editorial engraving of a bright video studio split in two: a producer pins a single index card beside a simple lever switch, while a young editor studies a monitor of many colored rhythm bands representing different channels' viewing patterns.

Do you need a model, or a rule nobody wrote down?

A lot of "we need AI for this" turns out to be a rule nobody has written down yet. Here's how to tell which one you're looking at, and what it looks like when a model really earns its place.

Editorial illustration for Field Note: Do not promote what you cannot pin.

Do not promote what you cannot pin.

Since last week's convincing demo, the model alias moved, the prompt was edited in a console and a tool gained a parameter. What you're about to promote isn't what was reviewed. Write down exactly what will run, and stop if any of it drifts.

Sunlit library desk: a person files blank slips into a drawer beside a laptop with an empty screen.

Decide what the agent may log before the first trace.

The first trace is already too late if you have not decided what stays, what gets masked, and who is allowed to unmask it.

Hands compare a polished vanity demo card with a worn work ticket labeled EVIDENCE, linked by a red thread and a measurement overlay.

Measure operational AI by the work, not the demo.

Token counts and thumbs-up ratings flatter a demo. For an agent doing real work, ask plainer things. Did the record show the job finished? What happened when it stopped halfway? Have its permissions quietly grown?

Hands press a red wax seal on a formal approval while an unused AUTO switch sits aside, marked MUST STAY HUMAN.

Some approvals should stay human.

When every agent action needs a human yes, people turn into slow middleware, and someone proposes removing the approvals altogether. Both go wrong. Some gates, like moving money or making a promise you can't take back, should stay with a person.

An agent needs a job, not a personality.

Start with a responsibility, a boundary, and a way to tell whether the work was done well.
