Subject: How do you write a package's deps to a file?

Hi guix! I want to output the deps of a package to
a writable file. Like say the "hello" world
package, I'd like to insert a file after, say the
install phase, so that later I could parse it and
serve it from a website. Here's a snip of what I
have:
#+begin_src scheme
(add-after 'install 'create-dependency-file
(lambda* (#:key inputs outputs #:allow-other-keys)
(call-with-output-file
(string-append
(assoc-ref outputs "out")
"/lib/python3.8/site-packages"
"/wqflask/DEPENDENCIES.txt")
(lambda (port)
(format
port "
#### System Inputs (generated from Guix)
|Name | Version | Home Page | Description |
|-----|---------|-----------|-------------|
|~a|
"
(apply
string-append
(map (lambda (input)
(let ((name (car input)))
(string-append
"| **" name "** | "
,(package-version
(specification->package name)) " | "
,(package-home-page
(specification->package name))
" |"
,(package-description
(specification->package name))
" |\n")))
inputs)))
))
))
#+end_src
That ^^ doesn't seem to work as I'd like it to. The output(truncated)
looks something like:
#+begin_src markdown
➜ guix git:(master) ✗ cat ~/opt/python3-genenetwork2/lib/python3.8/site-packages/wqflask/DEPENDENCIES.txt

#+end_src
Notice that the version, home page and description
are repeated across rows. Herein lies my question:
How would you fetch the details of the inputs(like
version, home-page, description) etc etc from a
modifed phase. Do I need to create a closure from
which I can import the modules like say _(use (gnu
packages))_. How do I do that if that's the case?
Is it also possible to get the same information in
a fine grained manner, like say get the
propagated-inputs instead of getting /all/ inputs?
