jupyter-ai-chat-commands

What it is and what it does

jupyter-ai-chat-commands is a JupyterLab extension that adds two built-in chat commands to Jupyter AI: @file: for attaching files to chat messages, and /refresh-personas for reloading locally-defined personas from the .jupyter/personas directory. It consists of both a Python server extension and a frontend NPM package that integrate with the Jupyter AI ecosystem.

The package requires JupyterLab >= 4.0.0 and Python >= 3.10. It depends on jupyter-ai-persona-manager, jupyter-ai-router, jupyter-server, and jupyterlab-chat. Installation is straightforward via pip, and the extension is enabled automatically; troubleshooting involves checking jupyter server extension list and jupyter labextension list if the commands do not appear.

Use it for:

• Attach local files to AI chat messages without manual copy-paste in JupyterLab notebooks.
• Reload custom AI personas from .jupyter/personas directory without restarting JupyterLab.
• Extend Jupyter AI chat interface with file-based context for code review or documentation tasks.
• Manage multiple AI personas for different workflows within a single JupyterLab session.
