- I would be more specific here, and instead change this insertion to
something like: "directory in order to execute commands in it."
- What about adding something like 'Commands in COMMAND_DIR are run
with a cwd of $HOME'
- Perhaps note that if a COMMAND_DIR program is invoked, 'argument' is
parsed as a command-line?

I would recommend displaying ~/$COMMAND_DIR instead, or
$HOME/COMMAND_DIR. The latter could be considered an information leak
though.

Sounds fine to me otherwise. Thanks for starting on this.
