I do not know what shellHook and nix-shell are, well I do not know what
they exactly do so it is hard to answer if an equivalent is there or
not. :-)
Well, I think some UI and interface is missing here, especially to have
a manifest containing the inputs of a package. Currently, this ugly:
--8<---------------cut here---------------start------------->8---
$ guix environment hello --ad-hoc python -r /tmp/example
$ guix package --export-manifest -p /tmp/example
;; This "manifest" file can be passed to 'guix package -m' to reproduce
;; the content of your profile. This is "symbolic": it only specifies
;; package names. To reproduce the exact same profile, you also need to
;; capture the channels being used, as returned by "guix describe".
;; See the "Replicating Guix" section in the manual.
(specifications->manifest
(list "htop"
"tar"
"gzip"
"bzip2"
"xz"
"file"
"diffutils"
"patch"
"findutils"
"gawk"
"sed"
"grep"
"coreutils"
"make"
"bash-minimal"
"ld-wrapper"
"binutils"
"gcc"
"glibc"
"glibc:static"
"glibc-utf8-locales"
"linux-libre-headers@5.4.20"))
--8<---------------cut here---------------end--------------->8---
And what you would like is something like to create a manifest.scm file
containing all the inputs of the package hello:
--8<---------------cut here---------------start------------->8---
(use-modules (guix)
(guix profiles)
(guix scripts environment)
(gnu packages base))
(make-manifest (package-environment-inputs hello))
--8<---------------cut here---------------end--------------->8---
but ’package-environment-inputs’ is not publicly exposed. Well, there
is probably other things in the public API doing something similar as
package-environment-inputs.
Once you have a profile, you can use it with “guix environment” and for
example launch it in a container:
--8<---------------cut here---------------start------------->8---
$ guix environment -C --profile=/tmp/example
--8<---------------cut here---------------end--------------->8---
However, there is no clean API to do it at the manifest.scm level. Ludo
proposed something long time ago but some love for this feature is
missing. :-) And the feature requests popups time to time. :-)

Hope that helps,
