There is only one reference to `curl` in the script, can you try to
substitute it with the absolute path and make it a regular input?  It's
good to avoid propagation when we can.

(install-file ...) has an unspecified return value, so please return #t here.

Maybe just "Control Kodi from the command line".

Similarly, this sentence can be reduced to something like
"@code{kodi-cli} is a tool for sending commands to a Kodi server using
JSON-RPC.".  Bash is an boring implementation detail IMO. :-)

"currently playing"

Same here.  Maybe it should be "currently playing item", since I assume
this works for music as well.

> address@hidden Play or queue to the current list YouTube video.

"List of YouTube videos"?

> address@hidden Interactive and noninteractive volume control.
> address@hidden Interactive navigation.
> address@hidden Send text.

What does this mean?  Arbitrary commands, or text notifications?

LGTM with some cosmetic improvements.  And welcome!

By the way, if you use Kodi from Guix, feel free to update the 18
snapshot if you can.  My media PC died a while back, and I didn't get a
replacement yet, so I have not been able to maintain the Kodi package.
