Why would you use an LLM for this? This sounds like a process easily handled by conventional logic, which would be cheaper, faster, and actually reliable… (The ‘notes’ part notwithstanding I guess, but calculations in general are definitely not a good use of an LLM)

But then for that you have distrobox, which is great. If that’s not enough, running another OS is also trivial, so that downside really is only ‘kinda’, as you say!
