By any chance, do you know what Claude Code's sandbox feature uses under the hood and how that relates to your solution ? From what I remember it also uses the native MacOS sandbox framework, but I haven't looked too deep into it and don't trust it fully
IIRC from a comment in another thread, it's marked as deprecated to stop people from using it directly and to use the offical macOS tools directly. But it's still used internally by macOS.
I'm not a native English speaker, but I read a lot of books in their original English. Being able to quickly look up a word you've never encountered is a god send
I find myself really missing this feature when I occasionally read a paper book, thinking about clicking the word on the page to get a definition.
