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.

What it costs to keep this loaded
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 | $0.00035 | $0.01502 |
| Opus 5.5 | $0.00014 | $0.00601 |
| Sonnet 5.5 | $0.00007 | $0.00300 |
| Haiku 4.5 | $0.00003 | $0.00150 |
Grade A, and why
agent-browser 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Browser
Agent Browser 是 NextClaw 调用的外部浏览器自动化 CLI。本 skill 只提供检查、安装引导、使用方式和安全边界，不包含 Agent Browser 的代码、npm 包或浏览器二进制。
能力边界
web_search适合开放式信息发现，Agent Browser 适合访问已知 URL、读取动态页面和执行真实网页交互。- 两者是独立能力。不要把 Agent Browser 的结果伪装成
web_search结果，也不要宣称它能稳定替代搜索服务。 - 本 skill 中的 Agent Browser 专指外部
agent-browserCLI；web_fetch、Chrome/Edge DevTools MCP 和 Browser Connector 是其他独立能力，不能冒充或混称 Agent Browser。 - 当
web_search未配置、未启用或请求失败，而浏览器仍可能推进任务时，先用一句话告诉用户将改用浏览器自动化，再继续本流程。 - 遇到验证码、登录墙、地区限制或搜索结果明显无关时，不得声称已经搜到或验证过信息。
首次使用与就绪检查
先检查外部 CLI 是否存在：
command -v agent-browser
agent-browser --version
如果 CLI 不存在：
- 明确告诉用户这会安装第三方全局 npm 包并下载浏览器运行文件。
- 用户当前请求若没有明确授权安装，先征得同意，不要静默安装。
- 获得授权后执行：
npm install -g agent-browser
agent-browser install
安装后或怀疑环境异常时先运行只读快速诊断：
agent-browser doctor --offline --quick
只有诊断表明需要修复且用户同意时，才运行可能重装浏览器或清理旧状态的 agent-browser doctor --fix。
本地模式不要求付费云浏览器，也不要求 Browserbase、Browser Use 等云 provider key。选择外部云 provider 时，才按对应服务的账户和计费规则处理。
先读取当前版本指南
Agent Browser 的命令会随版本演进。执行非简单任务前，先读取 CLI 自带且与当前版本匹配的核心指南：
agent-browser skills get core
只有需要完整参数或复杂工作流时再使用：
agent-browser skills get core --full
以这份版本匹配指南为准，不要只凭记忆猜测命令或复制过时示例。
标准执行循环
为每个任务使用独立、简短、仅含小写字母、数字和连字符的 session 名称，例如 nextclaw-research-1。同一任务的所有浏览器命令都带同一个 --session：
agent-browser --session nextclaw-research-1 open https://example.com
agent-browser --session nextclaw-research-1 snapshot -i -u
agent-browser --session nextclaw-research-1 get title
agent-browser --session nextclaw-research-1 get url
核心循环：
open打开明确 URL。snapshot -i -u读取可交互元素和链接；只读正文时可使用完整 snapshot 或针对元素执行get text。- 使用最新 snapshot 生成的
@eNref 交互。 - 页面导航、提交或动态重绘后先等待，再重新 snapshot；旧 ref 已失效。
- 用页面标题、最终 URL、可见文本或预期状态验证结果。
- 从实际打开和读取的页面记录来源 URL，不把搜索结果摘要当成已核验来源。
任务完成、失败或准备回复用户前，关闭本任务的 session：
agent-browser --session nextclaw-research-1 close
不要默认使用 close --all，它可能关闭其他并行任务的浏览器 session。
用浏览器进行信息发现
浏览器信息发现是受限制的替代路径，不等于搜索 API：
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.
- 1mo ago First seen · 127 lines · 35 tokens per session scan A 8d8abadf780e
agent-browser is a skill published in the GitHub repository Peiiii/nextclaw (262 stars, last pushed yesterday), licensed MIT. It adds 35 tokens to every session and 1,502 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
