Thank you for contributing to Guix! The following are some changes.

We normally include the "v" in the source URI itself, not in the
version. So, you'd end up with the following uri.

(string-append "https://github.com/jacktasia/dumb-jump/archive/v" version ".tar.gz")

Downcase TAGS to tags.

> +Jump performs best with The Silver Searcher `ag` or ripgrep `rg` installed.

Please put ag and rg within @command{} -- @command{ag} and @command{rg}.

This package appears to have tests. Could you add a check phase for
running them?

Also, the first line of the commit message should read

gnu: Add emacs-dumb-jump.

not

gnu: Add Emacs dumb-jump.

Could you send an updated patch?

Thanks!
