This is a monorepo for @vercel/microfrontends, a library that enables splitting large applications into independently developed and deployed microfrontends on Vercel. The package provides generic platform support for microfrontends in multiple frameworks, such as Next.js, SvelteKit, React Router, Vite, and React.

The above commands can be run for a particular package by using a filter option: pnpm checks -F <package name>. Use…

CLAUDE.md vs AGENTS.md

About CLAUDE.md

What is CLAUDE.md?

A file Claude Code reads at the start of every session. It holds the commands, conventions and warnings the agent needs for this project.

Where does it go?

At the repository root. Claude Code also reads CLAUDE.md files in subdirectories when it works there.

What should it contain?

Build and test commands, the project's layout, conventions that aren't obvious from the code, and mistakes to avoid. Short files tend to work better than long ones.

CLAUDE.md or AGENTS.md?

Claude Code reads CLAUDE.md; most other agents read AGENTS.md. Many projects keep one and point the other at it.
