It's pretty simple, really.

Before agents, good documentation wasn't a metric that got you promoted or warranted a raise. Writing features takes time, so developers didn't do it.

Agents require really strong documentation to work effectively. Almost every organization is volun-forcing their devs to use agents. Good documentation is now THE performance metric, except it's less about performance and more about keeping your job. So developers now write strong and extremely detailed documentation.

I wonder how tech writers feel about all of this.

(btw, most of that super detailed documentation is AI-generated, so there be dragons.)
