Rust Coding Agent

A small coding agent for the terminal, written in Rust. It sends your requests to Anthropic's Claude models and can run shell commands and read, write and edit files in the current directory.

Install

You need Rust, curl and unzip.

With minisign installed, the script also checks the release signature.

curl -fsSL https://raw.githubusercontent.com/ravshansbox/rust-coding-agent/main/install.sh | sh

Then start it with rca, the short name for rust-coding-agent.
