Hi Alex,

If you intend to use LLM for development/operations, I strongly recommend
something designed for that task like Claude Code/Opus 5, which can write,
run, and test the script.That doesn't mean it can do the job for you. You
still need to bring your own goals and expertise.

Regarding modules, that all depends on the goal. Don't expect this to just
work out of the box. The example script shows how things are done, but
probably doesn't meet your specific needs.

I should have said at the beginning that this was installed via a <br>
package manager, not compiled from source. Perhaps relevant?<br>
