Walkthrough

Agent、chain 和流式模型路径调整了回调处理方式。回调管理器会等待处理器完成；流式模型会等待 token 和 chunk 回调完成后再继续处理或结束。

Changes

回调完成时序

Layer / File(s)	Summary
配置回调管理器 packages/core/src/llm-core/agent/agent.ts, packages/core/src/llm-core/chain/agent_chat_chain.ts, packages/core/src/llm-core/chain/base.ts	Agent 和 chain 路径在添加处理器前启用 awaitHandlers。Agent 调用将配置后的管理器传入 bound.invoke。
等待流式回调完成 packages/core/src/llm-core/platform/model.ts	流式块处理等待 token 和 chunk 回调完成。流结束时等待 _finalizeStream 完成。

Change: Bug fix · Severity of issue fixed: Medium

Possibly related issues

• 开启 streamResponse 且 splitMessage 为 paragraph 时，回复末尾内容被丢弃（只发出前半截） #1066 — 该 issue 描述流式回复末尾内容丢失。本次改动等待流式 token 和 chunk 回调完成，涉及相同的回调时序问题。

Suggested reviewers: dingyi222666

Merge Risk: Moderate · up to e3f6d

The change makes the streamed-reply callbacks awaited so that the tail of multi-paragraph replies is no longer dropped. The agent path no longer leaks child-agent text to the parent. One earlier concern remains open in the streaming model code: a callback failure on the first chunk could cause a retry before progress is recorded. It should be checked before merge.

Review comments at @packages/core/src/llm-core/agent/agent.ts:
- Line 187: 更新 `manager.addHandler(handler)`，将父代理的文本转发处理器注册为不继承的本地处理器，确保子代理的 LLM
回调不会触发父代理的 `input.onToken` 和 `input.onChunk`，也不会将子代理的中间文本写入 `AgentStream.text`。

Review comments at @packages/core/src/llm-core/platform/model.ts:
- Line 271: 在流处理流程中更新 _handleStreamChunk
及其首块重试判定，区分回调错误与模型请求错误；仅模型请求错误可触发首块重试，回调错误应直接传播，避免因此再次调用 _createStream。
