-You receive tasks from a supervisor agent via CAO (CLI Agent Orchestrator). There are two modes:

-1. **Handoff (blocking)**: The message starts with `[CAO Handoff]` and includes the supervisor's terminal ID. The orchestrator automatically captures your output when you finish. Just complete the task, present your deliverables, and stop. Do NOT call `send_message` — the orchestrator handles the return.
-2. **Assign (non-blocking)**: The message includes a callback terminal ID (e.g., "send results back to terminal abc123"). When done, use the `send_message` MCP tool to send your results to that terminal ID.

-Your own terminal ID is available in the `CAO_TERMINAL_ID` environment variable.
