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 🙏

useskl

v0.2.1

Published

The skl CLI — publish, install, and version Agent Skills across Claude Code, Codex, Cursor, Copilot, Gemini & Grok. Cross-harness skill manager. Installs the `skl` command.

Readme

useskl

The skl CLI — publish a skill once, install it into any agent, rebuild it anywhere.

skl is a self-hosted, cross-harness skill manager for Agent Skills. Think of it as a package manager for the SKILL.md-based skills your coding agents use: version them, share them, and pin them in a manifest so a teammate or a fresh machine ends up with the exact same setup — across Claude Code, Codex, Copilot, Cursor, Gemini, and Grok.

npm install -g useskl
skl --version

Installs the skl command. (The package is named useskl because skl was already taken on npm — the command itself is skl.)

Why skl?

The skills ecosystem tells you how to write a skill. skl manages what happens after:

  • Distributeskl publish pushes a skill to your registry; skl install <skill> pulls one into a project. No copy-pasting folders between repos.
  • Reproduce — every project gets a skl.json manifest. skl install rebuilds the exact pinned versions on another machine (the npm ci of skills).
  • Cross-harness — one skill fans out to every agent you target. Pick your harnesses once; skl lands the files in each one's directory.
  • Yours — self-hosted and private-capable. Skills can be public or private, and nothing has to leave your network.

Quick start

skl login                  # authenticate this device
skl init                   # create skl.json, choose your target agents
skl install <user>/<skill>  # install a skill + record it in skl.json
skl install                 # rebuild every skill from skl.json (new machine / CI)
skl publish ./my-skill     # publish your own skill (versioned, immutable)

Pin a skill to an exact version (user/[email protected]) for reproducible installs, or track the latest (user/skill) and re-resolve on every skl install.

Run skl --help for the full command set — add, install, remove, info, list, scan, publish, fork, config, and more.

Other ways to install

# macOS / Linux — one-line installer (checksum-verified)
curl -fsSL https://useskl.com/install.sh | sh

# Homebrew (macOS + Linux)
brew install loopdoop/tap/skl

# Debian / Ubuntu — grab the .deb from Releases
sudo dpkg -i skl_*_amd64.deb

Or download a native binary directly from Releases.

How this package works

skl is a single Bun-compiled native binary, not a Node script. This package is a tiny launcher that execs the right binary for your OS/arch, installed automatically as an optionalDependencies package (useskl-darwin-arm64, useskl-darwin-x64, useskl-linux-x64, useskl-linux-arm64). npm pulls only the one matching your machine — there is no postinstall download. Windows and Alpine/musl aren't supported yet.
