browserstack is a skill for Claude Code, Codex from bestagentkits/agency-skills. It costs 44 tokens per session (1,084 once invoked), scanned A, a copy of browserstack, MIT.

A connection between Playwright tests and BrowserStack, a cloud service for testing websites in different browsers and on different devices.

In plain words
What is it for?
Use it to run Playwright tests across browser and device combinations, including Chrome on Windows and tests for browsers such as Safari or Firefox.
Why use it?
It lets a test suite check browser compatibility without relying only on the computers available locally.

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

browserstack 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 yesterday.

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.

Origin

This is a copy

100% identical to browserstack — 2 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.

BrowserStack Integration

Run Playwright tests on BrowserStack's cloud grid for cross-browser and cross-device testing.

Prerequisites

Environment variables must be set:

  • BROWSERSTACK_USERNAME — your BrowserStack username
  • BROWSERSTACK_ACCESS_KEY — your access key

If not set, inform the user how to get them from browserstack.com/accounts/settings and stop.

Capabilities

1. Configure for BrowserStack

/pw:browserstack setup

Steps:

  1. Check current playwright.config.ts
  2. Add BrowserStack connect options:
// Add to playwright.config.ts
import { defineConfig } from '@playwright/test';

const isBS = !!process.env.BROWSERSTACK_USERNAME;

export default defineConfig({
  // ... existing config
  projects: isBS ? [
    {
      name: "chromelatestwindows-11",
      use: {
        connectOptions: {
          wsEndpoint: `wss://cdp.browserstack.com/playwright?caps=${encodeURIComponent(JSON.stringify({
            'browser': 'chrome',
            'browser_version': 'latest',
            'os': 'Windows',
            'os_version': '11',
            'browserstack.username': process.env.BROWSERSTACK_USERNAME,
            'browserstack.accessKey': process.env.BROWSERSTACK_ACCESS_KEY,
          }))}`,
        },
      },
    },
    {
      name: "firefoxlatestwindows-11",

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.
