OpenCode ACP Control

Use when an AI agent needs to start, drive, or monitor an OpenCode CLI session programmatically over the Agent Client Protocol (ACP). Triggers include requests to "spawn OpenCode", "control OpenCode from another agent", "automate OpenCode over JSON-RPC", "resume an OpenCode session", or any task that requires the agent to act as an ACP client rather than an interactive user. Provides the JSON-RPC 2.0 framing, session lifecycle, polling strategy, permission-request handling, and update detection needed to wrap OpenCode from inside another AI agent.
