Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: httpbin.org.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

    Hosts contacted

    httpbin.orgundeclared

    What it found

    • packages/playwright-best-practices/rules/fixture-abort-cancel.md:114contacts httpbin.org
      const fetchPromise = fetch('https://httpbin.org/delay/10', { signal: abortSignal });

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned vitalics/playwright-labs at 59d65cfafc.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

This skill provides guidance and best practices for using Playwright, a Node.js library for automating browser actions. It focuses on writing reliable end-to-end tests, improving test maintainability, and ensuring consistent results across different environments. The skill aims to help users avoid common pitfalls and write more robust automated testing scripts.

When to use it

  • Automating web application testing: Use this when you need to automate UI tests for a website or web application.
  • Improving test reliability: Apply these practices when your existing Playwright tests are flaky or inconsistent.
  • Onboarding new team members: Share this skill with developers who are learning how to use Playwright effectively.
  • Refactoring legacy tests: Utilize the best practices to clean up and improve older, less maintainable Playwright test suites.

Key capabilities

  • Provides guidance on writing reliable end-to-end tests.
  • Offers advice for improving test maintainability.
  • Focuses on achieving consistent results across environments.
  • Addresses common pitfalls in Playwright usage.

Example prompts

  • "What are the best practices for handling asynchronous operations in Playwright?"
  • "How can I make my Playwright tests more resilient to network issues?"
  • "Suggest ways to improve the maintainability of a large Playwright test suite."

Tips & gotchas

This skill assumes you have a basic understanding of Node.js and Playwright concepts. While it offers best practices, applying them effectively requires careful consideration of your specific project's needs and context.
