CreateSkill

@danielmiessler Updated 2026-08-14

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).

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.
