Brief

@doodlestein describes an automated code-optimization workflow that repeatedly refactors projects for speed without changing behavior. The post emphasizes the 'extreme optimization' skill as a practical, iterative tool, and pairs that claim with concrete model recommendations—GPT 5.4 xhigh and Opus 4.6—and a reported benchmarked ceiling of 10x performance gains across many runs.

This skill is no joke. You just point it at your project and trigger it and come back in an hour and it has usually made some massive performance improvement in an isomorphic way. Then just rinse and repeat over and over again. It basically applies every leetcode and IOI trick.

Quoting @doodlestein

Which ones did you try? The extreme optimization one is super powerful. Try applying it repeatedly using GPT 5.4 xhigh and Opus 4.6.

I’ve applied it many dozens of times in some projects and seen performance improve 10x while everything is provably isomorphic. All benchmarked.
