I am not aware of a guix environment equivalent to shellHook, but I
suggest you checking out direnv[1].  It allows you to setup an
environment on a per-directory basis, everytime you enter a directory
the content of the `.envrc` file will be run in your shell.

There is also integration with Guix[2] so you could have an `.envrc`
file like this:

--8<---------------cut here---------------start------------->8---
use_guix <some-package> --ad-hoc git -L manifest.scm

echo "Environment created!"

[...]
--8<---------------cut here---------------end--------------->8---
