# Orchestrator Mode
### Sequential Chain Routing | Quality-Gated Escalation | Cost-Minimizing
Orchestrator mode takes a compound task, decomposes it into subtasks, and routes each
subtask to its optimal tier via advisor-mode. Between steps, a quality gate checks
whether the output satisfies the subtask's acceptance criteria. If the gate fails, the
subtask re-dispatches one tier up. If the gate passes, the chain continues.
**Core principle:**
> Route around failure, don't pick the "best" model. Orchestrator keeps every subtask
> on the cheapest tier that passes, and only escalates when a specific gate trips.
This is the complement to council-mode. Council compares models on the same task;
orchestrator runs a chain where each step picks its own tier and earns its escalation.

## BRAIN CHECK — Run Before Every Orchestrator Call
Brain root: resolved from `$CEREBRO_ROOT` env var or `~/.cerebro/profile.yaml`.
1. Verify advisor-mode is installed and provider-aware
2. **Local fleet (optional):** if `fleet_primary` is set, verify Ollama is reachable.
Cloud-only deployments skip this check — all tiers route to cloud.
3. Verify the task decomposes into ≥2 discrete subtasks (otherwise use advisor-mode directly)

## WHEN TO USE ORCHESTRATOR MODE
| Situation | Why Orchestrator |
|-----------|-----------------|
| Multi-step pipeline with different subtask types | Each step picks its own optimal tier |
| Research → draft → review chain | Decompose by knowledge intensity |
