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 | $0.00050 | $0.01142 |
| Opus 5 | $0.00025 | $0.00571 |
| Sonnet 5 | $0.00010 | $0.00228 |
| Haiku 4.5 | $0.00005 | $0.00114 |
Grade A, and why
browser-use 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 2d 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 — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Browser Use
Use the bundled Python script to control one isolated agent-browser session on the machine running the vBot server. This is a script-backed prototype, not a built-in Tool. On a remote Pi-server plus Windows Desktop Client setup it controls a browser on the Pi, not the user's Windows browser.
Installation
Windows PowerShell
- Run
node --versionandnpm --version. If either command is missing, install the current Node.js LTS release first, reopen PowerShell, and verify both commands before continuing. - Run
npm install -g agent-browser. - Run
agent-browser installto download Chrome for Testing. - Run
agent-browser --version. - Run
python {baseDir}/scripts/browser_use.py --session install-check doctorand require"ok": true. - Run
python {baseDir}/scripts/browser_use.py --session install-check start about:blank, require"ok": true, then runpython {baseDir}/scripts/browser_use.py --session install-check close.
Linux
- Run
node --versionandnpm --version. If either command is missing, install a supported Node.js release through the host's approved package or version manager, then verify both commands. - Run
npm install -g agent-browser. A user-local Node/npm setup provides a writable global npm prefix when needed. - On Debian, Ubuntu, Raspberry Pi OS, and compatible containers, run
agent-browser install --with-depsto install Chrome for Testing plus required system libraries. - On other distributions, run
agent-browser install; if launch verification fails, useagent-browser doctor --jsonto identify missing libraries. - Run
agent-browser --version. - Run
python {baseDir}/scripts/browser_use.py --session install-check doctorand require"ok": true. - Run
python {baseDir}/scripts/browser_use.py --session install-check start about:blank, require"ok": true, then runpython {baseDir}/scripts/browser_use.py --session install-check close.
The native agent-browser binary supports Windows x64 and Linux x64/ARM64. Keep agent-browser discoverable on the vBot server's PATH so vBot requirement checks and later Runs see the installation.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-use is a skill published in the GitHub repository Vironnimo/vbot (1 stars, last pushed 2d ago), licensed Apache-2.0. It adds 50 tokens to every session and 1,142 once invoked, about $0.0003 per session on Opus 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 2026-08-31.

dingtalk_channel_connect
Use a headed browser to automatically complete DingTalk channel integration for QwenPaw. Applicable when the user mentions DingTalk, developer console, Client ID, Client Secret, bot, Stream mode, binding or configuring a channel. Supports pausing when a login page is detected and resuming after the user logs in.
browser_cdp
Use this skill when the user explicitly wants to connect to a running Chrome browser, scan local CDP ports, specify a cdpport, or share a single browser across multiple agents/tools. By default browser opens no debugging port; pass an explicit cdpport only when the user wants another local tool to attach.
browser_cdp
当用户明确希望连接到已运行的 Chrome 浏览器、扫描本地 CDP 端口、显式指定 cdpport，或让多个 agent / 工具共享同一个浏览器时，使用本 skill。browser 默认不开放调试端口；仅当用户明确希望其他本地工具附加时才显式传入 cdpport。.
browser_visible
Use this skill when the user needs to control the browser launch mode for browser. By default browser is managed by Playwright and opens no debugging port (pass an explicit cdpport to let another local tool attach); headed controls whether the window is visible, and privatemode is kept for backward compatibility and…
