Google Cloud Generative AI Leader (GAIL) exam guide ebook built with Claude Code

In order to prepare for the Google Cloud Generative AI Leader (GAIL) exam I built the "long read" exam guide book with Claude Code. I passed the exam today and decided to share that book free on GitHub with whoever is interested -

https://github.com/vkorost/google-certified-ai-leader-guide

The GitHub project has the details about how that book was built.

I will just mention a few things here as a quick recap -

  1. The ultimate sources of truth were the official exam guide, the official study guide and the official Google Cloud documentation.
  2. However the exam requirements mention a few things not covered in the Google Cloud docs, because some of the things the exam want you to know is not about Google Cloud products at all, but IMO rather about *leading AI adoption the way Google understands it* (prompt engineering, implementation steps, responsible AI), so Google's own non-product writing was used to fill in the gaps (cited with URLs in the book's endnotes).
  3. Then subtitles from a few dozen YouTube videos where people talk about the exam were gathered and used for clues wrt what areas had to be covered in the book, so that there would be no surprises later. None of that info was used as a source of truth, but rather as a list of things to look up in the official docs first.
  4. The guide is not built by the exam sections, but rather in the order the decisions arrive: what the technology is, what you are choosing between, what Google sells, how to make the output better, and how to lead it. IMO that way the book reads more naturally.

ordering it by how decisions arrive instead of by exam section sounds like it would read much better on a first pass

Congrats on passing. Already grabbed the repo, the way you structured it around the decision flow rather than the exam blueprint is smart, most study guides read like a dry spec sheet. Curious how much Claude got wrong on the first pass that you had to correct from the official docs.

Thanks!
I did not have to correct anything by hand. I just had to ground Claude the right way to begin with. Then it checked itself against the docs. The repo's README gives the whole story how that was done.
And I instructed Claude to use a human voice to write it to avoid this "chewing on cardboard" feel that I usually have when I read most tech docs.
