What problem does it solve? Delegating Codex work without a routing policy wastes compute on trivial tasks or under-provisions high-risk production changes. This Skill maps each task's shape and risk directly to the smallest suitable model and effort tier. ## Core Features & Use Cases - Task-shaped routing: Sends mechanical transformations to Luna at low effort, investigation and code review to Terra at medium effort, and architecture, security, or production-risk work to Sol at high effort. - Delegation constraints: Enforces that a child route is strictly lower than its parent in both model order (Sol > Terra > Luna) and effort order (ultra > high > medium > low), and blocks Luna/low parents from delegating. - Catalog scenarios: Records explicit parent and child routes for narrow fixes, standard features, cross-repo contract changes, CI incidents, and production or IaC changes. - Use Case: When planning a cross-repo contract change with a CI incident, route the work to a Sol/high owner with Terra/medium investigation and QA children instead of escalating everything to the largest model. ## Quick Start Use the workflow-router skill to select the smallest suitable model and effort for this task.
