Testing skills make Claude verify instead of assert. The best-known are browser-driven: the official Webapp Testing skill and the Playwright plugin let Claude open a local app, click through it and read what actually rendered. Others shape the process around tests, such as Spec Kit for spec-driven development, PICT-based pairwise test design, and issue-to-fix workflows that write a failing test before the patch.

Install one when "done" in your project means a passing check rather than code that looks right. A browser skill is the difference between Claude saying a form works and Claude submitting it. Test-design skills help when coverage is thin and you want cases enumerated systematically instead of the three obvious ones. Teams that pair a testing skill with a hook that runs the suite after every edit get the tightest loop.

Like every skill, these live under ~/.claude/skills/<name>/ with a SKILL.md and load when a task matches their description; the entry page gives the install command. Browser skills need Playwright and its browsers on the machine, and they will drive a real browser against whatever URL you give them, so run them against local or staging. Open a new session after installing.
