A read tool returns up to 100 results by default (up to 1000 if the agent requests more), and the response size is limited by the MaxResponseSize parameter. If a result is cut off, the response says so, and the agent must narrow down the request.

history_get requires a time range (time_from and time_till) that is no wider than 7 days and starts no earlier than 7 days ago. The requested value type (type) must match the item's type of information; otherwise, an empty result is returned, which looks the same as an item with no data.
