      summary: Get agent context for rehydration
      description: 'Returns all messages relevant to the agent for execution context/rehydration.


        This includes:

        - All messages the agent sent (any type: text, tool_call, tool_result, thought, etc.)

        - All text messages that @mention the agent


        Use this endpoint to load the complete context an external agent needs to resume execution.


        Messages are returned in chronological order (oldest first).


        ## Pagination


        Use `cursor` + `limit` for cursor-based pagination (recommended). The response

        `metadata` includes `next_cursor` and `has_more`.


        `page` and `page_size` are deprecated and will be removed in API 2.0.0 (2026-10-01).
