Defined in:

Overview

Clamps request.page_size to a valid range and sets env["a2a.page_size"] for the agent.

Accepts a single integer — the maximum page size (also used as the default when the client doesn't specify one). Clamps to [1, max].

Part of the A2A::Server middleware stack — the max comes from A2A::Server.new(page_size: 50).
