Generating a Guide for a New Team Member

I asked Claude chat to make a prompt (which could later be turned into a skill) for inspecting a code repo and creating a human-readable overview / onboarding intro that should help a new joiner understand the problem or business domain that the software system exists to solve, the architecture and implementation choices that were made, and the typical engineering workflow for introducing new changes.

here’s the full prompt
and here’s the report that Google antigravity CLI produced when I called it with this prompt in the context of the Codebar Planner repo (checked out locally), a community-maintained open-source project built with Ruby on Rails.

Scenario

You're developing a system to analyze transactions for potential fraud.

You have a list of transactions, each with a variety of attributes like amount, currency, status, and a fraud score.

Your goal is to calculate total amounts for different currencies only for transactions flagged non clean.

You shall refactor ONLY the analyze_transactions method to be the shortest possible, without changing any other pieces of the code.

Teach by Learning, Lead by Teaching

Motivations for learning in tech and engineering:

Must-see locations in Leipzig

It depends, of course, on whether you’re looking for nature, culture, history, art, music, or night life, but here are some things to check out:

Obviously, city center, Augustusplatz, with its new Mein Building of Leipzig University (that looks like a church, because it was built where the GDR had destroyed a centuries-old church)
Thomaskirche, if you want to listen to organ music, or see the final resting ground of the mortal remains of J.S. Bach
Moritzbastei – just behind the city skyscraper that is visible from anywhere. This is an underground bar / concert location. Literally underground, with nice round vaults
The area around Markt is also worth walking around
Clara-Zetkin-Park (esp. area around Sachsenbrücke)

VIM Link dump

All these resources have actually helped me.

Learning VIM in 2014 – excellent blog post series, still not outdated. But, of course, you can google "learn VIM in 2019" instead.
VIM articles on the Giant Robots blog – super helpful tips and tricks, especially around the integration of VIM with TMUX and working with Ruby files in VIM
VIM Awesome – the catalogue of VIM plugins
Tim Pope – this guy is the Pope of VIM; he’s written a shit ton of plugins, most of which are pure gold.
VIM Casts – archived video series, a little old, but fantastic for learning the fundamental principles of VIM (and even ancient history behind its predecessor VI) – for instance, you can learn nice trivia such as why grep is called grep (this will make you the center
