Why Skills Over MCP?

MCP servers give agents tools, but tools alone are insufficient for complex workflows — tool descriptions tell an agent *what* a tool does, not *how to orchestrate* multiple tools to achieve a goal. Skills bridge this gap. They are structured "how-to" knowledge: multi-step workflows, conditional logic, and orchestration instructions that can run to hundreds of lines.

Skills are *context*, and MCP is a *context protocol*. Agents already connect to remote services over MCP to get tools — they can get the know-how to use those tools through the same channel. A remote MCP server can serve both its tools and the instructions for using them together, as a single atomic unit. This also enables automatic discovery (connect to a server, find its skills), dynamic updates (server-side changes flow without reinstall), multi-server composition (skills orchestrating tools across servers), and enterprise distribution (RBAC, multi-tenant, version-adaptive content) —
