Agent Skill: Playwright Best Practices

Empower your AI Agents to write, debug, and maintain Playwright tests with expert knowledge

Installation

npx skills add https://github.com/currents-dev/playwright-best-practices-skill

After installing, the AI will automatically use the skill when your tasks involve Playwright. No additional configuration is required.

What is an Agent Skill

Agent Skills are a new open standard for providing expertise to agents without bloating the context window. Created by Anthropic, skills are now available in all major AI development tools, including Claude Code, Cursor, VS Code, Google Gemini, and more.

At its simplest, a skill is a directory containing a SKILL.md file with metadata and expert knowledge that tells an agent how to perform a task in an opinionated way.

playwright-best-practices-skill/
├── SKILL.md          # Instructions + metadata
└── references/       # Topic-specific documentation
    ├── locators.md
    ├── assertions-waiting.md
    ├── debugging.md
    └── ...

Skills are progressively disclosed to preserve context. When an agent starts, only the skill's name and description are loaded. When a task matches the skill's purpose, the agent reads the full instructions and pulls in relevant references as needed.

This means the agent gets precise, expert knowledge exactly when it's relevant—without loading everything at once.

How is it used?

The skill triggers automatically when the AI infers you need help with Playwright-related tasks. You don't have to mention "skill" or "Playwright best practices"—just describe your task and the AI will use the skill when it's relevant.

Example prompts:

• "Fix this flaky login test" → The agent pulls in debugging and assertions guidance

• "Add a test for the checkout flow" → The agent uses test organization and locator best practices

• "Refactor these tests to use Page Object Model" → The agent references POM patterns and structure

• "Why is this test timing out in CI?" → The agent consults debugging and CI/CD references

• "Set up parallel execution for our test suite" → The agent uses performance and CI/CD guidance

The skill activates for tasks like:

• Writing new E2E, component, API, or visual regression tests

• Reviewing or refactoring Playwright test code

• Fixing flaky tests or debugging failures

• Setting up or changing test infrastructure and config

• Configuring CI/CD, parallel runs, or performance
