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 🙏

Readme

cmdlens

cmdlens is a POSIX-focused command line assistant that works in two directions:

  • explain an existing shell command in plain English
  • turn a natural-language request into a shell command

Before cmdlens executes anything, it shows the exact command, highlights risks, and asks for confirmation. While cmdlens is waiting on Codex, it shows progress on stderr. If Codex stalls or fails, cmdlens stops waiting and prints retry guidance such as codex login status.

Requirements

  • Node.js 22+
  • A local codex CLI installation
  • An active Codex/ChatGPT login in the local codex client

If you have not signed in yet, run:

codex login

cmdlens uses the local codex client for model-backed explanation and command generation, so the primary setup path does not require manually creating an API key.

Install

npm install

Usage

Explain a command:

npm run dev -- explain "tar -czf backup.tgz ~/Documents"

Generate a command from plain English:

npm run dev -- make "archive my Documents folder into backup.tgz"

Auto-detect command vs natural language:

npm run dev -- run "find all jpg files modified today"

Start interactive mode:

npm run dev

Flags

  • --json prints the structured result as JSON
  • --yes skips the execution confirmation prompt

Verification

Run the full test suite with:

npm run check
