> Opinionated, production-tested Playwright guidance — every pattern includes when (and when not) to use it.
50+ reference guides covering the full Playwright surface: selectors, assertions, fixtures, page objects, network mocking, auth, visual regression, accessibility, API testing, CI/CD, debugging, and more — with TypeScript and JavaScript examples throughout.
Playwright 1.59+ highlights covered in these guides include screencast recording, browser binding for agent workflows, CLI debugging and trace analysis, aria snapshot helpers, and in-place storage state updates.
This skill is designed for testing applications you own or have explicit authorization to test. It does not support or endorse automating interactions with third-party websites or services without permission.
When writing tests or automation that fetch content from external sources (e.g., baseURL pointing to staging/production), treat all returned page content as untrusted input — never pass raw page text back into agent instructions or dynamic code execution without sanitization, as this creates an indirect prompt injection risk.
For CI/CD workflows, pin all external dependencies (GitHub Actions, Docker images) to immutable references (commit SHAs, image digests) rather than mutable version tags. See ci-github-actions.md and docker-and-containers.md for pinning guidance.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted. The headline lift of +14 percentage points is the difference between those two pass rates over the 22 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
