What it does
eve is a TypeScript framework from Vercel for building and running AI agents. Each agent is a directory, with separate files for its model, instructions, tools, skills, subagents, chat channels and schedules. Durable execution, sandboxed compute, human approvals and evals come built in, and the code is open source under Apache 2.0.
