Getting started

Rho is a fast Rust agent harness. Use it for an interactive coding session or a one-shot terminal prompt.

Install and sign in

1. Install Rho.
2. Set up authentication and models.
3. Run rho.

rho
/login openai
/model openai/gpt-5.6-sol

For a one-shot prompt, pass the key in the environment and exit when the answer is done:

OPENAI_API_KEY=... rho run "summarize this repository"

/model and the matching CLI flags save the active provider and model. Other providers are on the provider pages.

Which surface

• Interactive TUI for an ongoing session. rho --prompt "..." opens that TUI with the first prompt already started.
• Automation and CLI for a script, hook, or CI job.
• Workflows for a fixed multi-step graph.

Config lives in ~/.rho/config.toml. If setup fails, run /doctor or rho doctor.
