eve

A filesystem-first framework for durable AI agents — instructions, tools, skills, channels, and schedules live as conventional files you can inspect, extend, and operate.

Install

via Positronick CLI

$positronick harness install eve --run

Official

$npx eve@latest init my-agent

eve is Vercel's filesystem-first framework for building durable AI agents: an agent is a directory whose core capabilities live in conventional files — instructions.md for the always-on system prompt, tools/ for typed callable functions, skills/ for procedures loaded on demand, channels/ for message transports like HTTP, Slack, and Discord, and schedules/ for recurring cron jobs. Scaffold one with npx eve@latest init, or add eve to an existing project by pointing init at a path. The eve package bundles its full documentation into node_modules so coding agents can read it locally.
