CLAUDE.md

The root instruction file that Claude Code reads at session start, containing your business context, routing rules, and operational patterns.

CLAUDE.md is the foundational file of any Knowledge OS installation. It tells Claude who you are, what you do, and how you work. A well-structured CLAUDE.md loads domain-specific rule files conditionally based on context, creating a modular instruction architecture that scales past 300+ files without conflicts. Think of it as the operating system kernel: it does not contain every instruction, but it knows where to find them.
