The endless thread is a smell

· 3 min read

A lot of new AI coding tools seem to be built around the same idea: start a thread, keep feeding it work, and let it run forever. I don't understand the appeal.

You can see the assumption hardening into product features. Claude Code lets you name sessions, find and resume them by name, branch them, and export their transcripts. Why would a coding conversation need a name? Cursor has editable chat titles, stored history, Markdown exports, and a way to pull old chats into the current one. They sound intuitive features to add at first, but they're based on the premise that a conversation is a durable unit of work rather than a temporary interface for completing a specific task.

Spec-driven development

Spec-driven development means treating a written specification as the source of truth: define the intended behavior first, then implement and validate the code against it.

I find the principle intuitive and exciting, but it has the same problem we've always had with documentation: drift.

Does AI change the best approach to separation of concerns?

Overlapping lines woven into a dense crosshatch

used to be fairly extreme about separation of concerns in my React code. A smart component file for logic. A dumb component file for rendering. A styled-components file for styles. An index file to tie them together. Four files per component, minimum.

It made each individual file very readable. You could generally fit one on a screen. If you needed to understand the render logic, you opened one file. If you needed the business logic, you opened another. The mental overhead of jumping between co-located files was low.
