Smart Model Routing

Dynamic model selection based on task complexity. Never use a sledgehammer where a scalpel will do — and never use a scalpel where you need a sledgehammer.

Core Philosophy

Static model assignments ("always use Sonnet for code") waste money on trivial tasks and produce poor results on complex ones. This skill scores every task across three signal categories and routes it to the appropriate model tier automatically.

Default rule: inherit parent model. Only override when the score clearly warrants a different tier. Never specify a model without a scoring reason.

Signal Categories

Three weighted categories are evaluated. Their scores combine into a single complexity score (0-20 typical range, can exceed).

Category 1: Lexical Signals (weight: 0.3)
