Nineteen open-licensed agent skills let an AI agent test a web app the way a person would: write the test first, open a real browser, click through the flows and report what broke. They come from Vercel Labs' agent-browser, Tech Leads Club, Anthropic, Matt Pocock, Jesse Vincent and lackeyjb.
All 19 are packaged as the QA & Testing plugin in Cuttlefish.MD, HackerNoon's license-checked skills marketplace. They follow the open Agent Skills standard, so they run in Claude Code, Codex CLI and 30+ other tools, and each is indexed in HackerNoon's SKILL.md Library.
