This skill should be used when the user asks to "create a new SDD skill", "scaffold a skill", "forge a skill", "build a new command", or mentions "skill creator". It manufactures production-grade SDD/IIKit skills with full scaffolding: SKILL.md, scripts, templates, references, hooks, evals, and knowledge graph registration. Use this skill whenever a new pipeline phase, utility command, or experience skill is needed — even if the user just says "I need a new /sdd command".
