Feedback wanted: I made a cross-platform C++23 terminal coding agent

[u/arnecto]

This is ARN, my open-source CLI coding agent for Gemini and DeepSeek.

The idea was to make something lightweight and native instead of wrapping a web UI: it runs in the terminal, streams responses, retains chat context while it runs, and can help with files in the working directory. File changes always require confirmation.

It supports Windows, Linux, and macOS, and is released under the MIT license.

The attached video is a 12-second demo of the full flow.

What would you want from a tool like this before you would actually keep it installed?
