Delegation & Hand-off

A single conversation can be handed off from one agent to another, mid-thread,
without you starting over. The active agent calls a hand-off tool, the session rebinds
to the new agent, its tools and instructions load, and the conversation continues — now
answered by the better-suited agent. You see a marker in the loop/flow view when this
happens.

This is opt-in: it lives behind the Agent Orchestration ability, which is off
by default. Without it, an agent simply can't reach other agents — the hand-off tools
aren't even loaded. The same ability also lets an agent kick off the prompt optimizer
(see The Prompt Optimizer).

Why hand off instead of one mega-agent? Specialised agents are easier to tune and keep
focused. A general assistant can triage, then delegate the database question to the
database agent and the page design to the page builder.
