RhoA lightweight agent harness inspired by Pi

Built in Rust to stay fast and memory-efficient.

Interactive TUI

Terminal-native

Run rho to open an inline terminal UI with streaming assistant output, reasoning deltas, compact tool blocks, and scrollback-friendly history.

Automation-ready

Use rho run for one-shot prompts in scripts, hooks, aliases, and CI jobs.

Rust-first

Rho is built in Rust instead of TypeScript to avoid the runtime overhead of a Node.js-based harness.
