OpenCode doesn't have agent teams yet. There are PRs open for it but I needed this now, so I built it as a plugin.
You get a lead agent that can spawn teammates, each with their own session and context window. They share a task board, can message each other, and the lead keeps you updated. Tasks can depend on other tasks so things unblock automatically.
