Anthropic published a new piece last week, The AI-Native SDLC Playbook. It is long, detailed, and worth the time. It also lines up closely with what I have been writing here for the better part of a year.

The argument at its center takes one sentence: code is no longer the bottleneck.

Everything in the document follows from it. Once agents write most of the implementation, the constraint moves to the stages on either side, the ones still running at human speed. Approval queues build. Controls sized for human output stop matching what arrives at them. Governance that meets monthly cannot govern work that ships hourly.

Their answer is to redesign the lifecycle rather than tune the individual tasks inside it. Intent gets written down once, by whoever had the idea, in their own words. Policies are encoded so they apply while the work is being produced, instead of being discovered in a review three weeks later. Each stage leaves something behind that the next stage can pick up, and that trail becomes the record of what was decided and by whom. People’s attention stops being spread thinly across the whole process and settles on the smaller number of points where somebody genuinely has to decide something.

I have been calling this Judgment-Driven Development since late 2025. Different words, same conclusion.

That is why I read the playbook twice. When you are the only one making an argument, it is a position. When a company that works on this with enterprises every day arrives at the same place from the opposite direction, it starts to look less like an argument and more like a description of where things are going.

There is one difference, and it is the one that interests me. Anthropic came at this from the execution side, asking what happens to the lifecycle when the code writes itself. I came at it from the judgment side, asking what people are actually deciding once that happens, and what has to be true for those decisions to be worth anything. That question is the book.

It should be out in a few months. If you want to know when, the newsletter is the place.
