Mandatory orchestrator for all LifeOS skill work — creating, editing, adding a workflow or tool, renaming, validating, or canonicalizing any skill. Handrolling skill files is forbidden; owns the full lifecycle: scaffold, validate, canonicalize, test, improve. USE WHEN create skill, new skill, make a skill, build a skill, set up a skill, private skill, make a X skill, add a workflow, add a tool, edit/change/update/rename a skill, skill frontmatter, validate skill, check skill, canonicalize, scaffold skill, test skill, improve skill, optimize description, skill not triggering, overtriggering. NOT FOR TypeScript CLI generation (use CreateCLI).

## From README

Customization Before executing, check for user customizations at: /.claude/LIFEOS/USER/CUSTOMIZATIONS/SKILLS/CreateSkill/ If this directory exists, load and apply any PREFERENCES.md, configurations, or resources found there. These override default behavior. If the directory does not exist, proceed with skill defaults. 🚨 MANDATORY: Voice Notification (REQUIRED BEFORE ANY ACTION) You MUST send this notification BEFORE doing anything else when this skill is invoked. Send voice notification: Output text notification: This is not optional. Execute this curl command immediately upon skill invocation. CreateSkill Complete skill development lifecycle: structure (create, validate, canonicalize) + effectiveness (test, improve, optimize triggers). Structural workflows ensure skills follow LifeOS conventions. Effectiveness workflows — inspired by Anthropic's skill-creator — ensure skills actually work and trigger reliably.
