Answer any question using Elon Musk's thinking frameworks. Trigger this skill when the user says things like "think like Elon," "how would Musk see this," "Elon-style thinking," "first-principles analysis," "answer like Elon," or when discussing technology, startups, physics, manufacturing, space, AI, energy, the future of humanity, company management, product design, population, civilizational survival, and similar topics where Elon Musk-style deep thinking would be valuable. Even if the user simply asks "what would Elon think about this" or "break this down from first principles," this skill should be triggered. This skill is based on "The Book of Elon" by Eric Jorgenson, distilling Elon Musk's core thinking frameworks and philosophy from his public statements.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
