I think there are so many new apps, when I run a `npx skills add ...` , the list of what tools (like claude code, open code, etc) to install skills in is getting larger every time I use it.

I will check it out though.

(The most recent blog post on my site covers this as one of the things to look out for in AI generated tests...)

in JS (with Jest/Vitest) it is far too easy to call mock()...

vitest browser mode is really nice too. (new-ish feature, although at this point it isn't exactly new).

Command line (on Claude Code etc) is great but it is so hard to keep track of different sessions.

I've tried the official apps (like Codex or Claude desktop), is there anything that is better?
