Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

jupyterlab_claude_code_extension

Published

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.

Manage Claude Code CLI sessions from inside JupyterLab. A left-sidebar panel lists every project under ~/.claude/projects/ deduplicated to one row per folder, marks live remote-control sessions with a green dot, and lets you jump back into any session by opening (or reactivating) a terminal pwd'd to that project and auto-running claude --resume <id>.

Claude Code Sessions panel

Features

  • Three-section side panel - Favourites, Recent (top 10 by activity), and All. Each section scrolls independently; Favourites disappears when empty
  • Live remote-control indicator - green dot on rows whose ~/.claude/sessions/<pid>.json is alive (verified via os.kill(pid, 0))
  • One-click resume - click a row to find an existing terminal pwd'd to that project (queried server-side from the pty's process tree) and reactivate its tab; only spawns a fresh terminal if none matches. Concurrent rapid clicks are coalesced
  • Smart name resolution - shows the user-set /rename name when available; auto-detected names (volatile across the same sessionId or 3+ token lowercase-kebab) fall back to the folder basename. Toggle the behaviour via the resolveSessionNames setting
  • Path-segment disambiguation - when two sessions share the same display name, the row reveals the minimum number of trailing path segments needed for each to be unique
  • Favourites - star a session via the right-click menu; persisted server-side at ~/.claude/jupyterlab_claude_code_extension.json
  • Layout restorer - panel visibility persists across JupyterLab reloads
  • Auto-disabled when the claude binary is not on PATH
  • Hover tooltip with relative path (vs JL root), last activity, message count, branch, first prompt, session id

Requirements

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