A similar question, is there something cli-composable? Something like:

  $ codellm -root /path/to/root -prompt - -connect $addr
  <input>^D
  <output>

Then it would be trivial to adapt to anything, e.g. as :'<,'>!codellm<CR>

Man all these wrappers and proxies that do the same thing again and again only to bury the essence.
