browser-cdp from uu201/character-arc is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add uu201/character-arc/browser-cdp@git:20260612.364daa3Pins git:20260612.364daa3 in mdr.lock. Pin the fingerprint instead.

Use this skill when you need to control a Chrome browser via CDP (Chrome DevTools Protocol) to reuse existing login sessions. Covers: launching Chrome in debug mode, opening URLs, waiting for page load, evaluating JavaScript, taking snapshots, and extracting auth tokens. Trigger phrases: browser automation, CDP, agent-browser, 浏览器操作, 操作浏览器, Chrome CDP, 复用登录态, extract token from browser.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Browser CDP 操作工具
通过 CDP 协议控制 Chrome，复用已有登录态，执行浏览器自动化操作。
## 前置条件
- macOS / Linux / Windows（实验性），已安装 Google Chrome
- Node.js 12+
- `agent-browser` 已安装：`npm install -g agent-browser`
> ⚠️ **首次启动会 kill 用户的常规 Chrome。** 在启动前必须征求用户同意（见下方"启动流程"），否则用户可能丢失未保存的标签页/草稿。
---
## 启动流程（skill-mode 强制步骤）
**第一步：探测当前状态（无副作用）**
```bash
node {SKILL_DIR}/scripts/setup-cdp-chrome.js 9222 --detect-only
```
输出形如：
```
CDP_STATUS=ready # 已就绪，可直接复用
CDP_URL=http://127.0.0.1:9222/json/version
BROWSER=Chrome/148.0.7778.168
```
或：
```
CDP_STATUS=needs-setup
CHROME_RUNNING=yes # 用户有 Chrome 在跑，启动会杀掉
CHROME_PID_COUNT=3
```
**第二步：根据探测结果分支**
- `CDP_STATUS=ready` → 直接使用 `agent-browser --cdp 9222 ...`，**不要运行 setup**。
- `CDP_STATUS=needs-setup` 且 `CHROME_RUNNING=no` → 安全启动：
```bash
node {SKILL_DIR}/scripts/setup-cdp-chrome.js 9222 --yes
```
- `CDP_STATUS=needs-setup` 且 `CHROME_RUNNING=yes` → **先用 AskUserQuestion 工具向用户确认**：告知会杀掉 N 个 Chrome 进程、可能丢失未保存工作；用户同意后再带 `--yes` 启动；用户拒绝则放弃这次自动化。
**为什么不能直接 `--yes`：** 脚本在非 TTY（即 skill 模式 / Bash 工具）下，如果检测到 Chrome 在跑而没有 `--yes`，会以退出码 3 报 `NEEDS_CONSENT: ...` 并中止，**不会**静默杀进程。这是有意的兜底——但 skill 流程仍应先问用户，而不是看到 3 就盲传 `--yes`。

How to install
mdr add uu201/character-arc/browser-cdp@sha256:8f9e48684bf9c2a9The line at the top of this page pins the label git:20260612.364daa3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
