Bounded collections and continuation
These response locations publish returned items with explicit bounds and continuation state:
$/oneOf/0/properties/data/properties/callees
Continuations and required actions
A response may include a structured continuation at the following schema location. Follow its tool call or user-action instruction instead of guessing how to continue:
