Route by task and constraints
In practice
Extraction, image understanding and final review can need different capabilities. Check input type, output format, budget and privacy for each step.
What to check
Capability selection, service health and data destination are distinct concerns. Record the actual model and deployment, not only an alias.
Common confusion
A common API does not ensure equal capabilities. A failure does not authorize sending data to another provider.
Tell your agent
Route each step by input type, output format, quality, budget and privacy. Record the actual model and service; allow only authorized compatible fallbacks without silently exceeding cost or data limits.
