exo

Why we included this project

Exo is built for people who want a long-running agent that can change its own code, prompts, and tooling at runtime rather than treating those parts as fixed. The harness keeps a canonical event log of everything it has tried and uses that history to improve itself incrementally, with an eye to avoiding loops. It comes as a minimal framework with a sandboxed Docker runtime, a scheduler for recurring tasks, and chat adapters for CLI, web chat, IRC, Discord, WhatsApp, Signal, and Slack. Because it keeps durable infrastructure like state and security separate from agent-specific logic, it is a reasonable starting point when you want an agent that evolves its own behavior over time instead of staying frozen at whatever you first configured.
