给我深度检索sproutclaw项目的webui后端是如何与sproutclaw项目交互通信的，如果我想把webui后端重构成go后端该怎么做效果如何


用户想要深度检索 sproutclaw 项目的 webui 后端是如何与 sproutclaw 项目交互通信的，并且想知道如果要把 webui 后端重构成 Go 后端该怎么做以及效果如何。

首先我需要了解 sproutclaw 项目的结构。让我先查看项目目录和关键文件。

bash

find /shumengya/project/agent/sproutclaw -maxdepth 3 -type f -name "*.md" | head -30

让我继续探索项目结构，了解 sproutclaw 的架构。用户提到"webui 后端"与 sproutclaw 交互通信，但我没有看到明显的 webui 目录。让我查看 packages 目录和更多项目结构。

用户说"webui 后端"，但 web-ui 看起来是一个纯前端库（没有 src 目录，只有 dist 和 example）。让我看看是否有其他后端相关的代码。也许用户指的是 coding-agent 或 agent 包中提供的某种后端服务。让我看看 coding-agent 和 agent 的源码。

find /shumengya/project/agent/sproutclaw/packages -maxdepth 3 -type d -name "src" | sort

find /shumengya/project/agent/sproutclaw/packages -maxdepth 3 -type f -name "package.json" | sort


看来 web-ui 包没有 src 目录，只有 dist（可能是编译后的产物）。让我看看 coding-agent 的 src 目录，看看它是如何与 web-ui 交互的，以及 web-ui 可能的后端通信方式。另外让我看看 web-ui 的 package.json。

这个项目没有 web-ui 的 package.json（只有 dist 目录），说明 web-ui 可能是在另一个包中编译的。让我查看根目录 package.json，以及 coding-agent 的 src 结构，看看是否有 web 服务器或后端相关的代码。

用户说"webui后端与sproutclaw项目交互通信"，但这里的 web-ui 看起来是一个纯前端组件库，没有后端。让我再深入看看是否有 web server 模式或某种后端。让我搜索 "web"、"server"、"http" 等关键词。

bash

找到了 http-dispatcher.ts 和 interactive-mode.ts。让我看看这些文件，以及 web-ui 相关的交互模式。
