No, you don’t, there is no requirement to not call external applications during documentation build process. You may have to invoke zsh which will do some parsing and serialize the result for Python which will do most of the job for creating documentation.

Zsh plugins are often sophisticated so maybe ZSD will be used, and (z) flag solves the effort-problem, even for Bash – just tried to run ZSD on an old 550-line Bash script with 9 functions (it implements youtube-dl queue, for slow networks), and it worked.
