This means these client features are only accessible from within tool/prompt/resource handlers using the new exchange argument.\n\nI have read and re-read the spec but I'm unable to find any mention to that at all. \n\nEven the diagram doesn't seem to sustain that hypothesis:\n\n```mermaid\nsequenceDiagram\n    participant Server\n    participant Client\n    participant User\n    participant LLM\n\n    Note over Server,Client: Server initiates sampling\n    Server-\u003e\u003eClient: sampling/createMessage\n\n    Note over Client,User: Human-in-the-loop review\n    Client-\u003e\u003eUser: Present request for approval\n    User--\u003e\u003eClient: Review and approve/modify\n\n    Note over Client,LLM: Model interaction\n    Client-\u003e\u003eLLM: Forward approved request\n    LLM--\u003e\u003eClient: Return generation\n\n    Note over Client,User: Response review\n    Client-\u003e\u003eUser: Present response for approval\n    User--\u003e\u003eClient: Review and approve/modify\n\n    Note over Server,Client: Complete request\n    Client--\u003e\u003eServer: Return approved response\n```\n\nWould it be possible to discuss the exact point of the spec that refers to this? I'm unable to find it.","author":{"url":"https://github.com/vromero","@type":"Person","name":"vromero"},"datePublished":"2025-04-07T21:48:10.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/119/java-sdk/issues/119"}
