Coverage

Generates code coverage reports for your Playwright tests, showing you exactly which parts of your application are being exercised during test runs. You'd reach for this when you need to identify untested code paths or justify your testing investment to stakeholders who love metrics. The skill handles both v8 coverage collection and Istanbul-style instrumentation, depending on what you're testing. It's genuinely useful for catching blind spots in your test suite, though don't fall into the trap of chasing 100% coverage at the expense of meaningful test scenarios. Works best as a periodic checkup rather than a gate on every commit.
