browser-automation-expert

browser-automation-expert is a skill for Claude Code, Codex from roedyrustam/vibes-plug. It costs 68 tokens per session (1,024 once invoked), scanned A, original, MIT.

A guide for building web agents that can browse pages, choose actions, and complete multi-step tasks using browser automation tools. It also covers avoiding bot detection and checking page appearance with vision-based comparisons.

In plain words
What is it for?
Use it to automate clicks and typing with Browser-Use, Stagehand, or Playwright, handle anti-bot techniques, rotate residential proxies, and capture screenshots for visual checks.
Why use it?
It helps automate workflows that are difficult to express with fixed selectors and investigate whether automated browsing or a webpage's visual output differs from expectations.

Token cost

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.

Security

Grade A, and why

browser-automation-expert 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 11d 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.

Autonomous Web Agent & Automation Expert

English | Bahasa Indonesia


English

Purpose & Overview

Deploy ultra-powerful autonomous web agents that can perceive, navigate, and execute complex workflows without human intervention. Use modern frameworks (Browser-Use, Stagehand) combined with hardcore anti-detection evasion techniques and Vision LLMs for visual QA.

Core Capabilities

  1. Autonomous Execution Frameworks

    • Integrate Browser-Use and Stagehand to allow LLMs to visually interpret DOM trees, inject semantic labels, and autonomously decide click/type actions.
    • Map complex multi-step workflows to semantic goals rather than brittle CSS selectors.
  2. Hardcore Evasion & Anti-Bot Bypassing

    • Playwright Stealth: Implement puppeteer-extra-plugin-stealth adapted for Playwright to spoof navigator.webdriver.
    • Fingerprint Masking: Spoof Canvas, WebGL, AudioContext, and WebRTC fingerprints.
    • Human Behavior Mimicry: Inject randomized delays, Bezier-curve mouse movements, and organic scroll patterns. Rotate residential proxies to bypass Cloudflare/Datadome.
  3. Visual QA & Diffing via Vision LLMs

    • Capture viewport screenshots and pipe them into GPT-4o, Claude 3.5 Sonnet, or Gemini 1.5 Pro.
    • Prompt the Vision LLM to perform layout regression checks, identify visual anomalies, or validate complex states (e.g., "Is the modal fully obscuring the background?").

Execution Protocol

  • Action: Initialize Stagehand or Browser-Use agent.
  • Action: Inject stealth scripts before page load.
  • Action: Pass screenshots to Vision LLM at key checkpoints for semantic validation.

Orchestration & Integration

  • Integrates with: web-scraper, autonomous-chaos-monkey, visual-qa-vision-agent, e2e-testing-expert.

Bahasa Indonesia

Tujuan & Gambaran Umum

Terapkan agen web otonom super kuat yang dapat melihat, menavigasi, dan mengeksekusi alur kerja kompleks tanpa campur tangan manusia. Gunakan framework modern (Browser-Use, Stagehand) dipadukan dengan teknik penghindaran deteksi bot tingkat tinggi dan Vision LLM untuk QA visual.

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.
