About this skill
What does the testing-browser-compatibility skill do?

Test across multiple browsers and devices for cross-browser compatibility. Use when ensuring cross-browser or device compatibility with BrowserStack, Sauce Labs, LambdaTest, or Kobiton. Trigger with phrases like "test browser compatibility", "check cross-browser", "validate on browsers", "test on real devices", "kobiton test". '

How do I install it?

Run `npx skills add jeremylongshore/claude-code-plugins-plus-skills --skill testing-browser-compatibility --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From jeremylongshore/claude-code-plugins-plus-skills, a repository with 2,596 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
