Is the Webapp Testing skill free?

Yes. The skill itself is free from anthropics/skills. SkillProof publishes the install command and an independent test verdict at no cost.

Does Webapp Testing work with Claude Code?

We tested it with Claude Code 2.x + Playwright on Jun 19, 2026. Verdict: Tested · Works. Drove a local app through signup, checkout and error flows via Playwright; caught a real regression our unit tests missed.

What is the Webapp Testing SkillProof Score?

8.8/10 — installs cleanly 4/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 4/5.

How do I install Webapp Testing?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Webapp Testing with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
