.claude/skills/mcp-playwright/SKILL.md

mcp-playwright is a skill for Claude Code from s-hiraoku/vscode-sidebar-terminal. It costs 47 tokens per session (984 once invoked), scanned A, original, MIT.

A guide for creating Playwright browser tests by carrying out each planned step in a real browser and recording the result. Playwright is a tool for automating and testing web pages.

In plain words
What is it for?
Use it to generate end-to-end tests, which check a complete user flow through the browser, including actions and expected results.
Why use it?
It reduces the gap between a written test plan and a test that actually matches how the site behaves.

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

mcp-playwright 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 10d 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.

Playwright MCP

Overview

This skill enables browser automation using Playwright through MCP. Playwright provides powerful browser control capabilities including navigation, element interaction, screenshots, and form handling.

When to Use This Skill

  • Navigating and interacting with web pages
  • Taking screenshots of web content
  • Filling out forms and submitting data
  • Testing web applications
  • Extracting information from web pages
  • Automating repetitive browser tasks

Quick Start Workflow

  1. Navigate to a page: browser_navigate
  2. Take a snapshot to get element refs: browser_snapshot
  3. Interact with elements using refs from snapshot: browser_click, browser_type

Core Tools

Navigation

browser_navigate - Navigate to a URL

mcp__playwright__browser_navigate({ url: "https://example.com" })

browser_navigate_back - Go back to previous page

mcp__playwright__browser_navigate_back({})

Page Analysis

browser_snapshot - Get accessibility tree (preferred for interaction)

mcp__playwright__browser_snapshot({})

browser_take_screenshot - Capture visual screenshot

mcp__playwright__browser_take_screenshot({
  type: "png",
  fullPage: true,
  filename: "screenshot.png"
})

Element Interaction

browser_click - Click an element (requires ref from snapshot)

mcp__playwright__browser_click({
  element: "Submit button",
  ref: "button[ref='submit']"
})

browser_type - Type text into an element

mcp__playwright__browser_type({
  element: "Search input",
  ref: "input[ref='search']",
  text: "search query",
  submit: true
})

browser_hover - Hover over an element

mcp__playwright__browser_hover({
  element: "Menu item",
  ref: "li[ref='menu']"
})

Form Handling

browser_fill_form - Fill multiple form fields

mcp__playwright__browser_fill_form({
  fields: [
    { name: "Username", type: "textbox", ref: "input[name='user']", value: "john" },
    { name: "Remember", type: "checkbox", ref: "input[name='remember']", value: "true" }
  ]
})

Changes

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.
