+## 可选抓包调试工具
+
+仓库提供了独立的 Cursor 协议抓包调试器。开发者在手动排查协议问题时，可以运行：
+
+```bash
+go run ./cmd/cursor-proxy-debugger
+```
+
+默认代理地址是 `http://127.0.0.1:9090`，调试界面是 `http://127.0.0.1:9091`。该工具可以辅助查看：
+
+- `agent.v1.AgentService/RunSSE`
+- `aiserver.v1.BidiService/BidiAppend`
+- Connect 帧、gzip 压缩内容、Protobuf 解码结果和原始二进制数据
+- 同一 `request_id` 对应的上下行消息
+
+开发者启动工具后，需要自行完成以下配置：
+
+1. 在 Cursor 的代理设置中，将代理修改为工具启动时显示的代理地址，默认是 `http://127.0.0.1:9090`。
+2. 在 Cursor 的 Network 设置中开启 HTTP/1.1。
+3. 从 `http://127.0.0.1:9091/api/ca.crt` 下载代理 CA 证书，并确保 Cursor 信任该证书。
+
+这只是供开发者手动使用的辅助工具，不属于自动化 Debug 流程。不要因为加载此指南就自动启动代理、修改 Cursor 或系统设置、安装证书，或操作 Cursor 发起请求。只有开发者明确表示已经启用抓包时，才把调试界面中的数据作为当前运行证据。调试结束后，提醒开发者恢复原来的 Cursor 代理和 Network 设置。
+
 ## Cursor 客户端格式化快照
 
 - 如果用户要求提取、格式化、刷新或规范化 Cursor.app 快照流程，使用 `cursor-app-formatted` skill。

+# Cursor Protocol Debugger
+
+[中文](README.md) | [English](README.en.md)
+
+This standalone local HTTPS debugging proxy captures Cursor's `BidiAppend` and `RunSSE` traffic. It does not modify Cursor, the system proxy, or the installed client.
+
+## Start
+
+Run the following command from the repository root:
+
+```bash
+go run ./cmd/cursor-proxy-debugger
+```
+
+Default addresses:
+
+- HTTP/HTTPS proxy: `127.0.0.1:9090`
+- Debugging UI: `http://127.0.0.1:9091`
+- MITM target: `api2.cursor.sh`
+
+The debugging UI opens automatically after startup.
+
+## Configure Cursor
+
+The tool does not modify Cursor automatically. After starting it, configure Cursor manually:
+
+1. Open Cursor's proxy settings and set the proxy to the address printed by the tool. The default is `http://127.0.0.1:9090`.
+2. Open Cursor's Network settings and enable HTTP/1.1.
+3. Download the proxy CA certificate from `http://127.0.0.1:9091/api/ca.crt` and make sure Cursor trusts it.
+
+Restore the original Cursor proxy and Network settings after debugging to avoid affecting normal network requests.
+
+## Build
+
+```bash
+go build -o bin/cursor-proxy-debugger ./cmd/cursor-proxy-debugger
+```
+
+## Options
+
+```text
+-proxy-addr       Proxy listen address; default: 127.0.0.1:9090
+-ui-addr          Debugging UI listen address; default: 127.0.0.1:9091
+-target-host      Host to decrypt and capture; default: api2.cursor.sh
+-max-exchanges    Maximum number of exchanges retained in memory; default: 200
+-open             Open the browser after startup; default: true
+```
+
+## Data Handling
+
+- HTTPS MITM is applied only to `target-host`; other CONNECT traffic passes through unchanged.
+- `RunSSE` is decoded incrementally using the 5-byte Connect frame header and supports per-frame gzip decompression.
+- `BidiAppendRequest.data` is further decoded as `agent.v1.AgentClientMessage`.
+- Requests can be sorted chronologically or in reverse chronological order and filtered by protocol `request_id`.
+- The UI supports Simplified Chinese and English, follows the browser language, and remembers a manual selection.
+- Captured traffic is stored only in process memory and is discarded when the process exits.
+- Sensitive HTTP headers such as `Authorization`, `Cookie`, and `Set-Cookie` are hidden in the UI by default.
+- Raw bodies are retained up to 2 MiB per side by default; forwarded traffic is never truncated.

+# Cursor 协议调试器
+
+[中文](README.md) | [English](README.en.md)
+
+这是一个独立运行的本地 HTTPS 调试代理，用于观察 Cursor 的 `BidiAppend` 和 `RunSSE` 通信。它不会修改 Cursor、系统代理或已安装客户端。
+
+## 启动
+
+在仓库根目录运行：
+
+```bash
+go run ./cmd/cursor-proxy-debugger
+```
+
+默认监听：
+
+- HTTP/HTTPS 代理：`127.0.0.1:9090`
+- 调试界面：`http://127.0.0.1:9091`
+- MITM 目标：`api2.cursor.sh`
+
+启动后会自动打开调试界面。
+
+## 配置 Cursor
+
+工具不会自动修改 Cursor。启动后需要手动完成以下配置：
+
+1. 打开 Cursor 的代理设置，将代理地址修改为工具启动时显示的地址，默认是 `http://127.0.0.1:9090`。
+2. 打开 Cursor 的 Network 设置，启用 HTTP/1.1。
+3. 从 `http://127.0.0.1:9091/api/ca.crt` 下载代理 CA 证书，并确保 Cursor 信任该证书。
+
+调试结束后，请恢复原来的 Cursor 代理和 Network 设置，以免影响正常网络请求。
+
+## 构建
+
+```bash
+go build -o bin/cursor-proxy-debugger ./cmd/cursor-proxy-debugger
+```
+
+## 参数
+
+```text
+-proxy-addr       代理监听地址，默认 127.0.0.1:9090
+-ui-addr          调试界面监听地址，默认 127.0.0.1:9091
+-target-host      需要解密的目标主机，默认 api2.cursor.sh
+-max-exchanges    内存中保留的最大请求数，默认 200
+-open             启动后是否打开浏览器，默认 true
+```
+
+## 数据处理
+
+- 仅对 `target-host` 执行 HTTPS MITM，其他 CONNECT 流量直接透传。
+- `RunSSE` 按 5 字节 Connect 帧头增量拆帧，支持逐帧 gzip 解压。
+- `BidiAppendRequest.data` 会继续解码为 `agent.v1.AgentClientMessage`。
+- 请求列表支持按抓包时间正序/倒序排列，并可按协议中的 `request_id` 过滤。
+- 调试界面支持简体中文和英文，可跟随浏览器语言并记住手动选择。
+- 抓包只保留在当前进程内存中；关闭进程后消失。
+- `Authorization`、`Cookie`、`Set-Cookie` 等 HTTP 头在界面中默认隐藏。
+- 单侧原始正文默认最多保留 2 MiB；代理转发的数据不会被截断。
