# Model Orchestration Policy
A fixed role split between model tiers, set by the user. The premise is
**quality-over-cost**: delegation floors are set at the effort levels Anthropic itself
recommends for intelligence-sensitive work ("start with xhigh for coding and agentic use
cases, high as the minimum for most intelligence-sensitive workloads" — official effort
guidance), not at the cost-saving end ("low ... like subagents"). When this policy and a
cost instinct conflict, the policy wins; surface the cost, don't silently downgrade.
## Role split
| Role | Who | Effort floor | Duties |
|------|-----|--------------|--------|
| **Orchestrator + Product Manager** | Top-tier session model (Fable) | session level | Directs everything. Directly: 서비스 방향성 수립·논의, 기획/스펙문서 **리뷰**, 기개발 기능 **개선**, 문제점(성능·보안) 발굴 — see below |
| **Doc author + core builder + V&V** | `opus` | **xhigh** (or `max`) | 기획/스펙/계획 문서 **작성·관리**, 핵심 구현(novel logic · architecture-touching · security surface), V&V |
| **Repetitive implementation + E2E** | `sonnet` | **high** (or above) | 반복 구현(pattern-following, boilerplate, example-driven migrations), E2E 테스트 작성·실행, research sweeps |
| **Orchestrator stand-in** (quota exhausted) | `opus` @ `max` | max | Takes over orchestration via a handoff — see "Orchestrator handoff" |
The orchestrator assigns a thinking/effort level **per task** at delegation time. Delegating
below a floor is a policy violation, not a tuning choice.
