Check out the section on search paths (info "(guix) Search Paths").

In essence, INFOPATH won’t be set if you don’t have an Info reader
(‘info-reader’ or ‘emacs’) in the profile, because then you’d have no
way to read the Info file.  Yet, you shouldn’t force a specific Info
reader on the user via ‘propagated-inputs’.

The story is similar for ‘guile-3.0’.  Here, you should wrap or modify
the ‘proba’ script such that it automatically adds its own
$PKG/share/guile/site/3.0 to its .scm search path (and likewise for .go
files).

See for example the ‘mcron’ or ‘shepherd’ script of the same-named
packages, or see the ‘wrap-guilescript’ phase of the ‘guilescript’
package.

HTH!
