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 | $0.00073 | $0.03177 |
| Opus 5.5 | $0.00029 | $0.01271 |
| Sonnet 5.5 | $0.00015 | $0.00635 |
| Haiku 4.5 | $0.00007 | $0.00318 |
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 4d 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.

Purpose & Overview
Deploy ultra-powerful autonomous web agents that perceive, navigate, and execute complex workflows without human intervention. Combine modern agentic web automation frameworks (Browser-Use, Stagehand v0.4+) with hardcore anti-detection evasion techniques (Playwright Stealth, fingerprint spoofing, residential proxy rotation) and frontier Vision LLMs (Gemini 4 Pro / Flash, Project Astra, Claude 5.1 Fable / 5.0 Computer Use, OpenAI GPT-5.6 / o3 / GPT-4.5) for pixel-accurate visual QA.
Core Capabilities
-
Autonomous Execution Frameworks (2026 Standard)
- Stagehand v0.4+: Natural language DOM perception with semantic actions (
page.act(),page.extract(),page.observe()). Avoid fragile CSS/XPath selectors. - Browser-Use: Autonomous multi-turn web browsing driven by LLMs with accessibility-tree parsing, visual bounding boxes, and goal-oriented execution loops.
- Stagehand v0.4+: Natural language DOM perception with semantic actions (
-
Hardcore Evasion & Anti-Bot Bypassing
- Playwright Stealth: Mask
navigator.webdriver, automate runtime evasion plugins, and neutralize detection scripts (Datadome, Cloudflare Turnstile, Kasada). - Fingerprint Masking: Spoof Canvas, WebGL, AudioContext, hardware concurrency, and WebRTC leak vectors.
- Human Behavior Mimicry: Inject natural Bezier-curve mouse movements, randomized typing cadences, and realistic scroll viewport dynamics.
- Playwright Stealth: Mask
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-automation-expert is a skill published in the GitHub repository roedyrustam/vibes-plug (113 stars, last pushed today), licensed MIT. It adds 73 tokens to every session and 3,177 once invoked, about $0.0003 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.
