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 | $0.00044 | $0.01084 |
| Opus 5 | $0.00022 | $0.00542 |
| Sonnet 5 | $0.00009 | $0.00217 |
| Haiku 4.5 | $0.00004 | $0.00108 |
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.
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.
How it starts
The opening of the file, as written. The whole thing — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 usernameBROWSERSTACK_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:
- Check current
playwright.config.ts - 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 ? [

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.

browserstack is a skill published in the GitHub repository bestagentkits/agency-skills (10 stars, last pushed 2mo ago), licensed MIT. It adds 44 tokens to every session and 1,084 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to browserstack, differing in 2 lines, and is treated as a copy.
