The Weekly Letter · In English

Specification
Economy Updates

A field note from the book being written. The Specification Economy argues that production has become cheap and specification has become the bottleneck — and every week, one idea from the manuscript-in-progress lands here first, before the book exists.

The Monthly Brief · English & Français

What's in an Issue

Short slots. Nothing padded.

What to remember from this issue

One or two plain sentences at the top. If you read nothing else, you can still use this one in your next meeting.

The field note

One idea from the chapter currently being written, told as a story, tested on you before it goes into the manuscript. Reply and argue with it; replies shape the book.

Try this week

One small exercise you can run on your own team in under an hour.

Seen this week

One real incident from the week: a capable system doing exactly what it was told, and what it was told was wrong. Primary source linked.

Someone said it better

One quote worth keeping: verbatim, attributed, timestamped. Never paraphrased, never generated.

One number

A single figure with its source, or no figure at all. A number that can't be verified doesn't run.

One door

A single next step, explained in one sentence: an article, the diagnostic, a waitlist. Never a catalog.
