Major refactoring of ourdigital-custom-skills with new numbering system: ## Structure Changes - Each skill now has code/ (Claude Code) and desktop/ (Claude Desktop) versions - New progressive numbering: 01-09 General, 10-19 SEO, 20-29 GTM, 30-39 OurDigital, 40-49 Jamie ## Skill Reorganization - 01-notion-organizer (from 02) - 10-18: SEO tools split into focused skills (technical, on-page, local, schema, vitals, gsc, gateway) - 20-21: GTM audit and manager - 30-32: OurDigital designer, research, presentation - 40-41: Jamie brand editor and audit ## New Files - .claude/commands/: Slash command definitions for all skills - CLAUDE.md: Updated with new skill structure documentation - REFACTORING_PLAN.md: Migration documentation - COMPATIBILITY_REPORT.md, SKILLS_COMPARISON.md: Analysis docs ## Removed - Old skill directories (02-05, 10-14, 20-21 old numbering) - Consolidated into new structure with _archive/ for reference 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
