Enforces ZERO TOLERANCE file placement rules for documentation and scripts. Use when (1) Creating any .md file, (2) Creating any .sh script, (3) Organizing documentation, (4) Writing guides or reports, (5) Adding utility scripts. CRITICAL RULES - NEVER create .md files in root directories (except README.md, CLAUDE.md), NEVER create .sh scripts in backend (except start.sh), ALL documentation goes in docs/ subfolders, ALL scripts go in scripts/ folder.
