>it presents the shell command on a REPL like line that you can edit first and hit enter to run it.

Oh genius, that's the best UX idea for the situation of asking an LLM to flesh out the CLI command without relying entirely on blind faith.

Even better if we can have that kind of behavior in the shell itself. For example if we started typing "cat list | grep foo | " and then suddenly realized we want help with the awk command so that it drops the first column.
