What it does The project is an AI programming assistant that runs in the command line. It can route requests to several LLM providers—OpenRouter, OpenAI, Claude, Zhipu, and any OpenAI-compatible endpoint. What the assistant actually does once it is running is less clear; the README never specifies whether it edits files, executes commands, or simply answers questions in a chat loop.

The interesting bit The most concrete detail is its Windows support. The authors fixed dependency and runtime issues tied to the AWS SDK and other packages on Windows, and they support image input via drag-and-drop or by pasting an image file path directly into the terminal. That is more Windows care than the average Node CLI README admits to.

Key highlights

Provider-agnostic: works with OpenRouter, OpenAI, Claude, Zhipu, and generic OpenAI-compatible APIs.
Explicit Windows fixes for AWS SDK and other Node packages that fail on Windows.
Image input on Windows via drag-and-drop or pasted file paths in the terminal.
Built in TypeScript and released under the Apache 2.0 license.
Acknowledges contributions from shareAI-lab/Kode-cli.

Caveats

The README is vague about the agent’s actual capabilities—file editing, command execution, and project planning are all unspecified.
Cross-platform parity is unclear; only Windows-specific behavior and fixes are documented.

Verdict Worth a look if you want a multi-provider terminal AI and spend most of your time on Windows. Skip it if you need a clear feature list before trying a tool.
