What separates them from the general-purpose\n  tier is fit, not capability: each is built for one job, by the\n  engineer who will maintain it. No published practice sets out how to build one end to\n  end. The pieces are everywhere (function-calling APIs, the Model Context Protocol, code\n  agents to pair with), but the practice that chains them lives in podcasts, blogs, and\n  leaked system prompts.
