Best model router should be owned by your team

A retweeted view suggests that the best model router should be owned by the team personally:
- A smart agent in your harness supporting sub-agents.
- A skill explaining the strengths of each model with usage guidance.
- A table listing the costs of each sub-model.
The decision context needs to live in your model and harness, calibrated with evals over the narrow tasks your customers care about. It is essentially an eval generation problem to find the Pareto optimum for your task.
