# Model Router Choose how a task should be executed before resolving which concrete model should run it. Select the simplest eligible route that can meet the quality target. Models, tools, compute, agents, reviewers, and escalation are means, not goals. Host, runtime, organization, and repository rules remain authoritative. This skill supplies its own minimum routing, verification, and human-escalation contracts; a host may impose stricter requirements. ## Load references only when needed - Define success and evaluation with [quality and evaluation](references/policies/quality-and-evaluation.md). - Express requirements and compare candidates with [capability routing](references/policies/capability-routing.md). - Check data, tool, and action eligibility with [tool permissions](references/policies/tool-permissions.md). - Choose reasoning intensity or budget with [compute allocation](references/policies/compute-allocation.md) and, for optimization, [cost frontier](references/policies/cost-frontier.md). - Consider delegation, review, or parallelism with [agent topology](references/policies/agent-topology.md). Load the [economical-worker profile](references/profiles/coordinator-with-economical-workers.md) only when that pattern is a real candidate. - Manage context pressure with [context economy](references/policies/context-economy.md); load [memory and state](references/policies/memory-and-state.md) only for pause, resume, or checkpoint decisions. - Retain run evidence with [
