Expensive routes should be reserved for tasks where quality or risk justifies the cost. Small formatting and sorting tasks rarely need the strongest model.
Use lean routes for simple structuring and escalate only for complex reasoning or final review.
Start with a narrow boundary: which website, space, file, recipient or decision is affected? This makes the task reviewable instead of turning it into a broad catch-all request.
A useful work order is: “Assess whether this task needs a lean route or a stronger model, and split the work if useful.” For important cases, add that uncertainties must be marked visibly instead of being filled in silently.
Pay special attention to risk, review duty, privacy and later findability. These points decide whether the result is only useful for the moment or can be found, checked and continued by the team later.
Do not choose the highest quality setting by habit.
Good routing protects budget without lowering important quality.
