The fundamental coding agent abstraction is the CLI. It’s not a UI or form factor preference, it’s rooted in the fact that agents need access to the OS layer. Coding agents are, at their core, computer-use agents. They run programs, create new ones, install missing ones, scan the filesystem, read logs. More than text editors, they’re *automating your computer* at a low level. It’s more accurate to think of Claude Code as “AI for your operating system” than a continuation of the copilot autocompletion → IDE AI assistance paradigm. Another consequence is that it works for any computer. Your desktop computer, but crucially, also the ones running in the cloud. 𝚗𝚟𝚒𝚖 nerds like yours truly always liked that it’s an editor that runs on your Mac but also any machine you 𝚜𝚜𝚑 into. Imagine if you could launch a million Claude Codes concurrently to tackle a bug, find cybersecurity threats, process your issue backlog, build features based on user feedback, run QA… That’s why we’re building http://vercel.com/sandbox as the infinite compute layer for agents.
