A thin deterministic orchestrator checks instructions, duplicates, fields, context and reliability before a typed handoff to isolated specialist knowledge and bounded tools, then handles results or escalation.

Summary: Meta describes replacing a broad agent with a roughly 1,300-line orchestrator that routes requests to 14 context-isolated specialists across more than 20 workflows. The design uses deterministic routing, typed handoffs and narrow tool access. Meta reports much faster delivery and fewer edits, but the results come from its internal engineering environment.

Why it matters: Separate coordination from domain work when one agent’s context becomes noisy. Define explicit routes, minimal handoff fields and bounded tools, then compare completion quality and human revision rates before assuming that additional specialists improve reliability.
