Test report

Verdict: Tested · Works
Score: 8.8/10
Tested: Jun 19, 2026
Environment: Claude Code 2.x + Playwright

Drove a local app through signup, checkout and error flows via Playwright; caught a real regression our unit tests missed.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

Installs cleanly 4/5
Triggers reliably 5/5
Output vs. baseline 9/10
Docs & honesty 4/5

What it does

End-to-end testing where Claude actually clicks through your app — navigation, forms, edge cases — and reports failures with reproduction steps. Requires Playwright installed locally.

Install

git clone https://github.com/anthropics/skills
cp -r skills/webapp-testing ~/.claude/skills/
npm i -D playwright

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
