How to setup your Claude code project?
TL;DR
Most developers skip the setup and just start prompting. That's the mistake.
A proper Claude Code project lives inside a .𝗰𝗹𝗮𝘂𝗱𝗲/ folder. Start with 𝗖𝗟𝗔𝗨𝗗𝗘.𝗺𝗱 as Claude's instruction manual. Split it into a 𝗿𝘂𝗹𝗲𝘀/ folder as it grows. Add 𝗰𝗼𝗺𝗺𝗮𝗻𝗱𝘀/ for repeatable workflows, 𝘀𝗸𝗶𝗹𝗹𝘀/ for context-triggered automation, and 𝗮𝗴𝗲𝗻𝘁𝘀/ for isolated subagents. Lock down permissions in 𝘀𝗲𝘁𝘁𝗶𝗻𝗴𝘀.𝗷𝘀𝗼𝗻.
There are two .𝗰𝗹𝗮𝘂𝗱𝗲/ folders: one committed with your repo, one global at ~/.𝗰𝗹𝗮𝘂𝗱𝗲/ for personal preferences and auto-memory across projects.
The .𝗰𝗹𝗮𝘂𝗱𝗲/ folder is infrastructure. Treat it like one.
The article below is a complete guide to 𝗖𝗟𝗔𝗨𝗗𝗘.𝗺𝗱, custom commands, skills, agents, and permissions, and how to set them up properly.

Most engineers overcomplicate locking.
Here’s the truth:
Optimistic Lock → Application-level control
Pessimistic Lock → Database-level control
Optimistic = let everyone edit, check for conflicts on save.
(Think Google Docs.)
Pessimistic = block everyone else until you’re done.
(Think library book.)
Rule of thumb
If retry is cheap → use Optimistic
If retry is expensive → use Pessimistic

Libgen, Sci-Hub, and Z-library had millions of pirated academic books and papers.
So, they were shut down. We shouldn't use them anyway.
We should help billion-dollar academic publishers get richer.
Anyway, here's how to access these libraries:
