If it's distributed by Haskell people then you can generate the package spec form by:

$ guix import stackage shellcheck

Or

$ guix import hackage shellcheck

It will be printed to the standard output device. You can then copy it from there.

The difference is that the first one, stackage, has long-term-support (i.e. well-tested and stable) package combinations. The latter has newer packages.

But it seems that shellcheck is not distributed that way. Then you have to write it by hand. It works really similar to any other package.

So put the following into gnu/packages/haskell.scm :

(define-public ghc-json
  (package <---- this block was generated by: guix import hackage json
    (name "ghc-json")
    (version "0.9.1")
    (source
      (origin
        (method url-fetch)
        (uri (string-append "https://hackage.haskell.org/package/json/"
                            "json-" version ".tar.gz"))
        (sha256
          (base32
            "18l5027vc68hnnxrxlnyl59vkkg95a92m1zzms0dqiby2r6pxdcn"))))
    (build-system haskell-build-system)
    (inputs
     `(("ghc-syb" ,ghc-syb)
       ("ghc-mtl" ,ghc-mtl)
       ("ghc-text" ,ghc-text)

(define-public shellcheck

The "ghc-" prefix is only used for libraries. I think from your description that shellcheck is not a library. Is that correct?
