FWIW that’s what ‘--with-source’ does.

Like Marius wrote, you could pass #:select?

  (local-file …
              #:select? (git-predicate "/home/rob/puzzledb/tools"))

Build processes for origins work in the global namespaces, with access
to the network and to everything.  So I think something like this should
work:

  (origin
    (method url-fetch)
    (url "/home/rob/puzzledb/tools")
    (sha256 …))

HTH!
