GitHub·medium signal

Vercel Labs released an open-source reference application for building and running background coding agents on Vercel infrastructure. At 3,074 stars with 735 gained today, it implements a key architectural principle: 'the agent is not the sandbox' — agents run separately from execution environments, communicating through tools. Features include durable multi-step execution, sandbox hibernation/resumption, automatic GitHub PR creation, and session sharing via read-only links.
