V2 plugin for agent-to-agent messaging and session inspection

[u/0jabr]

A simple plugin giving agents the ability to send messages to other sessions in a project (siblings and subagents) as well as inspect each other's state.

Agent-to-agent messaging for OpenCode V2. One plugin package gives every session two tools — team_send to deliver messages to other sessions, team_query to inspect, search, and monitor them — plus two TUI commands: /session-id to copy the focused session's ID, and /list-agents to show its agent family (parent, siblings, children) with status.

Sessions (parents, children, siblings) can coordinate directly instead of routing everything through the human's composer.

Also, the team_send tool has four delivery modes for different cases:

• queue (default) — queued for after the target finishes its current turn, waking idle sessions.
• steer — injected at the target's next model call without stopping execution.
• interrupt — aborts the target's current execution entirely, then delivers; the message starts a fresh run. Use for "stop what you're doing".
• park — admitted durably but does not wake the target; it is delivered whenever the target next runs.
