Hello, I'm GymCoding!

As the project grows, CLAUDE.md grows with it, causing Claude to follow the wrong rules... I'm feeling the limits of trying to manage everything with a single CLAUDE.md in a monorepo...

I've noticed many people have been sharing these concerns lately. So, I've put together a proper explanation in this additional lecture!

This lecture is not just a tip for splitting CLAUDE.md into multiple files. It is a proven strategy that allows Claude to automatically read manuals only when working on a specific folder by dividing them accordingly.

What is covered in this lecture

• The core principle of sub-CLAUDE.md — a structure that automatically loads only when working in that specific folder

• Umbraco CMS Real-world Case Study — How to manage large-scale projects with 23 CLAUDE.md files

• Braintree/PayPal Real-world Case Study — 26 CLAUDE.md Operation Patterns by Payment Feature

• .claude/rules/ vs sub-directory CLAUDE.md — Comparison table on when to use which

• File Size Guidelines — The 30-line root CLAUDE.md case study from CopilotKit (29K ⭐)

The core of this lecture is not about reducing rules, but how to make only the rules of the folder you are currently working in visible to Claude!
