Playwright Agents

Introducing Playwright Agents, three custom agent definitions designed to guide LLMs through the core process of building a Playwright test:

• 🎭 planner explores the app and produces a Markdown test plan
• 🎭 generator transforms the Markdown plan into the Playwright Test files
• 🎭 healer executes the test suite and automatically repairs failing tests

Run npx playwright init-agents with your client of choice to generate the latest agent definitions:

# Generate agent files for each agentic loop
# Visual Studio Code
npx playwright init-agents --loop=vscode
# Claude Code
npx playwright init-agents --loop=claude
# opencode
npx playwright init-agents --loop=opencode
