This article explains why I use OpenCode as the stable local harness around replaceable remote AI models. The core distinction is simple: my agents, permissions, skills, and workflow should remain mine, while model providers such as Anthropic, OpenAI, OpenRouter, or Z.ai stay external and swappable. I also describe why one-time configuration matters in practice: the same setup can be reused in the OpenCode terminal, CodeNomad, IntelliJ IDEA, PhpStorm, Zed, and Buzz through ACP. The point is not novelty. It is privacy, sovereignty, provider independence, and not rebuilding the same harness every time a new interface shows up.
