jupyterlab-claude-code-extension 1.1.25

Browse, resume, and manage your Claude Code CLI sessions from a JupyterLab side panel. One click reactivates the right terminal - no duplicate tabs, live remote-control indicator, and favourites for the projects you keep coming back to.

jupyterlab_claude_code_extension

Browse, resume, and manage your Claude Code sessions from a JupyterLab side panel. One click reactivates the right terminal, no duplicate tabs, with a live indicator showing which sessions are currently active.

Features

• Three-section side panel - Favorites, Recent, and All projects, each scrolling independently
• Live indicator - a green dot marks sessions that are currently running somewhere
• One-click resume - click a row to jump back into that session in a terminal. If a terminal for the project is already open, it's reused instead of duplicated
• Favorites - star projects you keep coming back to via the right-click menu
• Remove - drop a project's Claude history from the panel via the right-click menu; the history folder is moved to the trash (it honours JupyterLab's "move files to trash" setting), not deleted permanently
• Clean up parallel sessions - when a project has accumulated extra sessions beyond the main one, a right-click menu item (showing the count in brackets) removes them all, keeping only the main session; removed files honour the same trash setting
• Search - fuzzy filter toggled by the funnel button next to refresh
• Presentation modes - label rows by session name (so a /rename shows through), folder name, or path relative to the JupyterLab root
• Hover tooltip with project path, last activity, message count, branch, and session id
• Auto-disabled when the Claude Code CLI is not installed

Requirements

• JupyterLab >= 4.0.0
• Python >= 3.10
• claude CLI on PATH

Install

Developers must install via the project Makefile (which orchestrates clean, build, and pip install of the resulting wheel):

make install

End-users can install the published package from PyPI:

pip install jupyterlab_claude_code_extension

[!WARNING] package.json pins webpack: 5.106.0 and chalk: 4.1.2 in both resolutions and overrides. Do not remove these. webpack >= 5.106.1 changed its module-federation share identifier format and crashes the unmaintained license-webpack-plugin (split('=')[1].trim()) that @jupyterlab/builder injects into every production build; the duplicate chalk@2.4.2 pulled by duplicate-package-checker-webpack-plugin crashes on Node 24+ in the build-isolation install. Without the pins, make publish and CI fail on python -m build.

Uninstall

pip uninstall jupyterlab_claude_code_extension
