Do

  C-u M-x checkdoc-current-buffer RET

and learn that it also has a docstring problem:

  Argument ‘prefix’ should appear (as PREFIX) in the doc
  string

At the stage when it does nothing, it seems 'poke' has so many
problems already!

I also don't get any warnings but the ones you mention,

  Warning: Unused lexical argument `prefix'
  Warning: reference to free variable ‘...’

and that's on
