Interesting. This probably works just as well the other way around. One of the reasons I like using Opus is that the code it writes aligns much more closely with my repository (of which I still hand-wrote most), compared to most other models. That makes a big difference compared to the GPT models for instance, whose code is correct and works well but looks a bit out of place most of the time, especially for larger edits (this makes things harder to review).
Be careful, there is a codex strike force in the hn bushes who is ready to jump and call you claude pilled at the sight of someone claiming to have a good experience with claude.
I recently built a Small Web Discovery feature for the WebLibre Android browser that unifies multiple sources (currently only Wander and Kagi Small Web). The feature is still very alpha, in the upcoming weeks I will look into adding more sources. Documentation here: https://docs.weblibre.eu/weblibre/small-web.html and there are some screenshots in this Wander issue: https://codeberg.org/susam/wander/issues/11
