yoyo is an open-source terminal coding agent written in Rust that autonomously evolves its own source code — reading its code, planning improvements, implementing changes, running tests, and committing every few hours with no human-written code. It also functions as a practical coding assistant with a streaming REPL, 90+ slash commands, multi-file edits, git management, and test-gated failure recovery.
Use cases
- autonomous coding agent that improves its own codebase
- terminal AI assistant for navigating and editing codebases
- make multi-file code edits from the command line
- agent that runs tests and manages git commits automatically
- study how a self-evolving AI agent works in public
- AI agent that responds to GitHub issues and discussions
- REPL-based coding assistant with slash commands
When to choose
- you want a terminal-based AI coding agent with deep git and test integration
- you're interested in self-improving/autonomous agent experiments with a fully public history
- you prefer a lightweight Rust CLI over heavier agent frameworks
- you want an agent that engages with its community via GitHub issues and discussions
When to avoid
- you need a battle-tested, human-maintained coding assistant with guaranteed support
- you're uncomfortable with code written autonomously by an AI agent
- you need IDE integration or a graphical interface
- you require strict code review processes before changes land
