Usage

rho

For one-off prompts:

rho run "summarize this repository"

Inline shell

Prefix TUI input with ! to run a command locally and add its command, output, and exit status to model context. Use !! to run it without adding anything to context. The composer uses distinct colors and labels for the two modes.

Rho defaults to Bash on Unix-like systems and PowerShell on Windows. Choose another detected shell under /config -> Inline shell.
