Playwright
Authoring Playwright tests, shipped in the Playwright repository itself — locators, waiting, fixtures, traces.
Installation
$ npx skills add microsoft/playwrightThe CLI's unit is the repository, so this installs everything in microsoft/playwright, not playwright-dev alone. It writes into whichever agent directories it finds — Claude Code, Codex, Cursor, Copilot, Windsurf, Zed.
Summary
Authoring Playwright tests, shipped in the Playwright repository itself — locators, waiting, fixtures, traces.
- Reach for it when your generated E2E tests are full of arbitrary sleeps and brittle CSS selectors.
- Sits in Test — proving the change does what it claims — and finding the assertions that were never written.
- Assumes web.
- Published by Playwright, who ship the thing it is about — a stronger claim than a well-regarded engineer having written something good.
- Installing pulls the whole microsoft/playwright repository, which is the CLI's unit — not this file alone.

The skill itself
The full text lives with its publisher and changes when they change it. Read it there rather than here — a mirrored copy of somebody else's procedure goes stale silently, and this page would have no way of telling you.
