Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00094 | $0.02372 |
| Opus 5.5 | $0.00038 | $0.00949 |
| Sonnet 5.5 | $0.00019 | $0.00474 |
| Haiku 4.5 | $0.00009 | $0.00237 |
Grade A, and why
browser-cdp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to browser-cdp — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Browser CDP 操作工具
通过 CDP(Chrome DevTools Protocol)连接 Chrome,复用登录态并执行浏览器操作。
前置条件
- macOS / Linux / Windows(实验性),已安装并使用过 Google Chrome,来源 profile 已存在
- Node.js 20+
agent-browser已安装:npm install -g agent-browser
启动或重建时,若需结束 Chrome 进程,先按下方流程征得同意;未保存的标签页或草稿可能丢失。
启动流程(每次都按这个顺序)
下文 {SKILL_DIR} 指本 skill(browser-cdp)的目录。
第一步:探测当前状态(无副作用)
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=needs-setup且CHROME_INSTALLED=no→ 本机没找到 Chrome,告诉用户先安装并用它登录一次需要的网站,不要运行 setup。CDP_STATUS=ready且本次只需连接 → 直接使用agent-browser --cdp 9222 ...,不要运行 setup。- 明确请求
--reset/--profile→ 即使 ready 也走重建,按下方「需要结束 Chrome 时」处理。 CDP_STATUS=needs-setup且CHROME_RUNNING=no→ 安全启动:node {SKILL_DIR}/scripts/setup-cdp-chrome.js 9222 --yesCDP_STATUS=needs-setup且CHROME_RUNNING=yes→ 按下方「需要结束 Chrome 时」处理。
需要结束 Chrome 时(同意流程):凡是会结束正在运行的 Chrome 的命令(Chrome 在运行时启动、--reset、显式 --profile),都按这三步走:
- 带上原定选项加
--dry-run跑一次,看会结束几个 Chrome 进程; - 告诉用户会结束 N 个 Chrome 进程、未保存的标签页或草稿可能丢失,问是否继续;
- 用户同意后,去掉
--dry-run、加--yes重跑;用户拒绝就放弃这次自动化。
非 TTY 调用中,Chrome 在运行且未传 --yes 时,脚本以退出码 3 报 NEEDS_CONSENT: ... 并中止。取得同意后再重跑,不自动补 --yes。
换端口:9222 被别的程序占用时可以换一个端口(如 9333),之后所有 agent-browser --cdp 命令用同一个端口,扫榜脚本加 --port 9333,查资料助手传 cdp_port: 9333。
启动脚本选项
| 选项 | 说明 |
|---|---|
--detect-only |
只探测,不修改任何状态 |
--yes |
已征得同意,跳过交互提示 |
--reset |
启动前清空 ~/chrome-debug-profile(登录失效时用) |
--profile <name> |
指定来源 profile(默认 Default,如 "Profile 1");显式传入即重建 |
--dry-run |
打印将执行的步骤,不执行 |
退出码:0 成功 / 1 通用错误 / 2 用户拒绝(TTY)/ 3 需同意但缺 --yes。
常用操作
打开页面并等待加载
agent-browser --cdp 9222 open "<URL>"
agent-browser --cdp 9222 wait 3000
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

browser-cdp is a skill published in the GitHub repository zenstory-ai/oh-story-dsh (629 stars, last pushed today), licensed MIT. It adds 94 tokens to every session and 2,372 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to browser-cdp, differing in 0 lines, and is treated as a copy.
