Frequently Asked Questions

FAQPage Schema
How to install MetaMask extension skills?▼

Run `npx skills add MetaMask/metamask-extension --all -g -y` in your terminal to install all skills in this suite globally.

What do these MetaMask agent skills do?▼

They teach your AI coding agent the exact build commands, testing standards, and security rules needed to contribute safely to the MetaMask browser extension.

How do I run MetaMask E2E tests with an AI agent?▼

The skills route your agent to the Page Object Model testing standards, so it writes specs that call page objects and flows instead of raw locators.

Do these skills work with Claude Code and Cursor?▼

Yes. The AGENTS.md instructions are read natively by Claude Code, Cursor, and other agent frameworks that support the standard.

Can the agent commit code on its own?▼

No. The rules forbid committing or staging unless you explicitly ask, and pull requests are opened as drafts using Conventional Commits titles.
