Raven: The Self-Improving Agent Harness

Raven is an open-source agent harness by EverMind that enables agents to improve across runs by continuously refining their tools, skills, memory, code execution, policies, and working environment. Built on top of EverOS — which provides durable user memory, agent memory, and world knowledge across sessions — Raven turns successful workflows into reusable Agent Templates and digital workers.

Key features:

  • CLI + TUI + gateway interfaces with messaging gateway support (Telegram, Discord, etc.)
  • Built-in tool library, skill framework, and policy management
  • Runs on Linux, macOS, WSL2, and native Windows (PowerShell installer)
  • One-line install: curl -fsSL https://raven.evermind.ai/install.sh | bash
  • Available models/gateways configurable for various LLM providers

The project has 1,100+ GitHub stars and is developed by EverMind AI, a team focused on self-improving agent infrastructure.
