Model routing works best when simple steps stay lean and critical checks receive more capability. A subject line, a table cleanup and a contract review do not carry the same risk or cost profile.
Use cheaper routes for structuring and stronger routes for complex reasoning, sensitive documents 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: “Suggest the right model route for this task and explain where quality matters and where a lean route is enough.” For important cases, add that uncertainties must be marked visibly instead of being filled in silently.
Pay special attention to files, sources, responsibilities and expected output format. 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 use the strongest route by habit for every small formatting task.
Routing becomes a quality and cost control tool rather than a hidden technical setting.
