playwright-skill

playwright-skill is a skill for Claude Code, Codex from agentverus/agentverus-scanner. It costs 46 tokens per session (3,300 once invoked), scanned A, a copy of playwright-skill, MIT.

A browser-automation tool built around Playwright, a library for controlling web browsers with code. It can detect development servers, create temporary test scripts, fill forms, take screenshots, and check pages, login flows, responsive layouts, and user experience.

In plain words
What is it for?
Use it to test web pages, submit forms, check login flows, capture screenshots, and validate responsive design and user experience.
Why use it?
It removes the need to perform repeated browser checks by hand. It also lets you test a running local website across concrete interactions and screen sizes.

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

playwright-skill 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

88% identical to playwright-skill — 13 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 — 460 lines — stays where its author put it; the contents beside it link to each section on GitHub.

IMPORTANT - Path Resolution: This skill can be installed in different locations (plugin system, manual installation, global, or project-specific). Before executing any commands, determine the skill directory based on where you loaded this SKILL.md file, and use that path in all commands below. Replace $SKILL_DIR with the actual discovered path.

Common installation paths:

  • Plugin system: ~/.claude/plugins/marketplaces/playwright-skill/skills/playwright-skill
  • Manual global: ~/.claude/skills/playwright-skill
  • Project-specific: <project>/.claude/skills/playwright-skill

Playwright Browser Automation

General-purpose browser automation skill. I'll write custom Playwright code for any automation task you request and execute it via the universal executor.

CRITICAL WORKFLOW - Follow these steps in order:

  1. Auto-detect dev servers - For localhost testing, ALWAYS run server detection FIRST:

    cd $SKILL_DIR && node -e "require('./lib/helpers').detectDevServers().then(servers => console.log(JSON.stringify(servers)))"
    • If 1 server found: Use it automatically, inform user
    • If multiple servers found: Ask user which one to test
    • If no servers found: Ask for URL or offer to help start dev server

  2. Write scripts to /tmp - NEVER write test files to skill directory; always use /tmp/playwright-test-*.js

  3. Use visible browser by default - Always use headless: false unless user specifically requests headless mode

  4. Parameterize URLs - Always make URLs configurable via environment variable or constant at top of script

How It Works

  1. You describe what you want to test/automate
  2. I auto-detect running dev servers (or ask for URL if testing external site)
  3. I write custom Playwright code in /tmp/playwright-test-*.js (won't clutter your project)
  4. I execute it via: cd $SKILL_DIR && node run.js /tmp/playwright-test-*.js
  5. Results displayed in real-time, browser window visible for debugging
  6. Test files auto-cleaned from /tmp by your OS

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.
