A terminal-based coding agent built in Rust.
Features
- Interactive TUI — full terminal UI with scrollable conversation log, streaming responses, and an in-app model picker
- Multi-provider support — switch between Google Gemini, Anthropic Claude, and OpenAI models on the fly
- Built-in tools — the agent can read/write/edit files and run bash commands autonomously
- Agentic loop — the model plans and executes multi-step tasks using tool calls until the job is done
