> Chrome Extension Rewrite: Finally, I rewrote the element selector of the Chrome extension (the one that lets you select/pointer elements in the browser) the “traditional” way, by hand. Why? Because I realized that my struggles to explain it to AI were actually a problem of abstraction. Once I fixed that, the result was clean, solid, and perfectly ready for future iterations — this time with AI. I realized that getting these abstractions right was writing the spec. And that’s the kind of work architects do.
