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

nessie-skill

Install the NESSIE (NS Dutch Railways) design system agent skill into your AI tool of choice — Claude Code, Cursor, Codex, or GitHub Copilot — with one command.

It vendors the skill (AGENTS.md + skills/ + reference/) into a .nessie/ folder in your project and writes the small entry file each tool reads, pointing it at .nessie/AGENTS.md.

Usage

# from your project root
npx nessie-skill init            # auto-detects your tool(s)
npx nessie-skill init --all      # configure every supported tool
npx nessie-skill update          # refresh .nessie/ to the latest docs

Options

| Flag | Description | | :--- | :--- | | --tools <list> | Comma list: claude, cursor, codex, copilot (default: auto-detect) | | --all | Configure every supported tool | | --dir <path> | Target project (default: current directory) | | --ref <ref> | Branch, tag, or commit of the skill repo (default: main) | | --repo <o/n> | Source repo (default: gertjankooy/nessie) |

What it writes

your-project/
  .nessie/                          # vendored skill (safe to commit or gitignore)
    AGENTS.md  skills/  reference/
    .nessie-version                 # records repo + ref + install time
  AGENTS.md                         # → points to .nessie/AGENTS.md (Cursor, Codex)
  CLAUDE.md                         # → points to .nessie/AGENTS.md (Claude Code)
  .github/copilot-instructions.md   # → points to .nessie/AGENTS.md (Copilot)
  .cursor/rules/nessie.mdc          # Cursor rule (alwaysApply)

Entry files use a managed block (<!-- nessie:start … -->), so re-running never duplicates content and never overwrites your own instructions — it updates only its block.

How it stays current

init/update download the skill from the public repo tarball at the given --ref (default main), so you always get the latest docs without republishing this package. Pin a release with --ref v1.2.0 if you want a fixed version.

Notes

  • Requires Node 18+ (uses built-in fetch).
  • The source repo is public and read-only — no token or auth needed.
  • To read an actual Figma design (audits, design-to-code), your tool still needs the Figma MCP / Dev Mode MCP server connected — the skill files can't provide that.
  • Maintainer commands (/sync-docs, /sync-tokens, /docs-coverage) live in the skill repo's .claude/ and are intentionally not vendored by this installer.
