Model routing

Choose the
engine.

A model has a capability ceiling. Effort controls how much room it gets to reason. Route by uncertainty and verification cost.

LOW

Bounded rhythm

Lookup, small edits, formatting, and transformations with clear checks.

MEDIUM

Default work

Normal implementation where the contract is clear but context matters.

HIGH

Ambiguity

Planning, architecture, security judgment, and hard failures.

Two knobs

Capability
× effort

ROUTING RULE strong model + high effort → frame ambiguity · light model + low effort → bounded execution · raise one knob at a time → compare evidence

Sequence

Spend judgment
where it compounds.

01
Plan Strong model: scope, risks, acceptance, and worktree split.
02
Build Focused worker: smallest context and lightest model that can pass.
03
Review Independent pass when missed issues cost more than the call.
