Feature request: debug any command

I (and, I can imagine, many people) have a common use case where I want to run a command in the terminal and get q to debug it if something goes wrong (missing dependency etc.).

I have a few options to achieve that now:

1. Open Q chat and ask it "debug this command $cmd" or "make sure that $cmd runs successfuly". Works reasonably well, but I am relying on an LLM to execute exactly $cmd (and then some debugging command, and then $cmd).
2. Run $cmd myself and if something goes wrong go to (1). All the same issues as (1)
3. Do the loop myself: run $cmd, ask Q to fix the error then run $cmd

would be great to explicitly have it as a feature
