- **term:** Agent Orchestration
- **category:** core
- **short_def:** The coordination layer that routes tasks between multiple agents and tools — deciding what runs, in what order, and how results are combined.
- **long_def:** Orchestration is the control plane of a multi-agent system: an orchestrator (or 'supervisor' agent) decomposes a goal, dispatches sub-tasks to the right agents or tools, manages dependencies and parallelism, and assembles the final result. It is the difference between a pile of agents and a system.

- **contrast_with:** Unlike a single agent's internal loop, orchestration coordinates across many agents and tools — a level above any one agent's reasoning.
- **example:** An orchestrator handling 'research and draft a report' dispatches search agents in parallel, waits for all, then hands their findings to a writer agent.

- **why_it_matters:** Orchestration is how the agentic web scales from one agent to many; agent-gateways and A2A give the orchestrator standard rails to route over.
