Expand description

消息内容。Partial* 是流式增量,与之配对的成型变体在内容完整时发出。

序列化为 { "type": "tool_call", ... },方便前端按 tag 分发。

Variants§

§

UserMessage

用户提交的一条消息。

Fields

§text: String
§

ReasoningStarted

一次推理开始(provider 即将被调用)。

§

PartialAssistantMessage

assistant 文本的流式增量。(预留:需 provider 支持 token 流式后才发出。)

Fields

§delta: String
§

AssistantMessage

一条成型的 assistant 消息(含 thinking / text / tool_use 块)。

Fields

§

PartialToolCall

工具调用参数的流式拼装增量。(预留:同上。)

Fields

§call_id: String
§name: String
§delta: String
§

ToolCall

模型决定调用某工具(参数已成型)。

Fields

§call_id: String
§name: String
§arguments: Value
§

ToolOutput

工具执行期间的实时原始输出(如 bash 边跑边吐)。纯前端展示用: 不进 transcript、模型也看不到——它不是 ToolResponse 的一部分。 模型看到的真正结果始终是下面那条完整的 ToolResponse(后台工具任务则是 {id, running} 信封)。 不带 call_id —— 归属“当前正在执行的工具“(非只读工具独占串行,任一时刻至多一个)。

Fields

§chunk: String
§

ToolResponse

工具执行结束的完整结果(模型看到的、也是会落进 transcript 的那条消息)。 后台工具任务超时让步时,这里就是 {id, status:"running", …} 那个异步信封。

Fields

§call_id: String
§is_error: bool
