OpenCode 2.0 ships with reworked service and tool calling
What happened
On October 15, the Hacker News front page reported a major OpenCode 2.0 update. The update connects the terminal user interface (TUI), web interface and desktop app to a local background service that runs automatically, and reworks the API. For tool calling, Code Mode by default turns MCP tools into functions that scripts can compose and call; for task execution, it adds background sub-agents and asynchronous shell commands. TUI plugins are listed as a stable feature, and the update also provides an @opencode/sdk that is still in development.
