Bounded collections and continuation

These response locations publish returned items with explicit bounds and continuation state:

$/oneOf/0/properties/data/properties/affectedDocuments

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:

$/oneOf/1/properties/continuation
