19 Agent Skills Test Your Web App With Playwright and Real Browsers

Nineteen open-licensed agent skills enable an AI agent to test a web application in a manner similar to human interaction. The skills originate from Vercel Labs agent-browser, Tech Leads Club, Anthropic, Matt Pocock, Jesse Vincent, and lackeyjb. They are packaged as the QA & Testing plugin within Cuttlefish.MD, a license-checked skills marketplace on HackerNoon.

These 19 skills adhere to the open Agent Skills standard, ensuring compatibility with Claude Code, Codex CLI, and 30+ other tools. Each skill is indexed in HackerNoon's SKILL.md Library.

The skills cover a range of functionalities, including browser automation through a CLI built for AI agents by Vercel Labs, running agent-browser on AWS Bedrock by Vercel Labs, debugging and automating the browser via Chrome DevTools MCP server by Tech Leads Club, recording a demo video of a feature on a real desktop with real cursor by Tech Leads Club, reverse-engineering a site's internal API and generating a client by Vercel Labs, exploring a web app systematically to find bugs and UX problems by Vercel Labs, automating Electron desktop apps by Vercel Labs, and more.

To utilize all 19 skills, one can execute a single command /plugin marketplace add hackernoon/cuttlefish-agent-skills /plugin install qa-testing@cuttlefish. For Codex CLI, Cursor, or other agents supporting the standard, one must clone the repository and copy the plugins/qa-testing/skills/ directory into the agent's skills folder, such as .agents/skills/.

Each skill retains its license and an ATTRIBUTION.md file, crediting its author and source commit. To explore the full library, visit hackernoon.com/skills, and star Cuttlefish.MD on GitHub.
