The CLAUDE.md Guide Every Claude Code User Needs

Описание: There's one file in your project that quietly controls everything Claude Code does. Most people get it completely wrong — and I was one of them. My CLAUDE.md had grown to over 1,500 lines, and I thought I was being thorough. I wasn't.

In this video, I walk through why bloated CLAUDE.md files actually make Claude perform worse, the research behind instruction budgets and context rot, and a practical framework for writing a CLAUDE.md that's under 300 lines but far more effective. I cover subfolder files, lazy loading, @imports, and a complete real-world example.

What's covered:
Why longer CLAUDE.md files degrade Claude's performance
The instruction budget: how many instructions Claude can reliably follow
Context rot research from Chroma
The WHAT / WHY / HOW framework for structuring your file
Writing specific, actionable instructions (not vague platitudes)
Subfolder CLAUDE.md files and lazy loading
@imports for referencing external docs on demand
A complete 45-line example that actually works
Growth strategy: start minimal, grow organically
Maintenance: auditing and pruning your CLAUDE.md
