This is the meta tool for spinning up new agents and MCP servers when existing skills don't cover what you need. It walks you through the full workflow from persona design to knowledge encoding, claims about 45 minutes to get a production-ready agent. Comes with templates for technical experts, creative roles, and orchestrators, plus concrete anti-patterns like avoiding knowledge dumps and vague personas. The real value is in having a structured process for agent architecture rather than just dumping requirements into a prompt. Best paired with skill-coach for quality review once you've built something.
