Curated by Skill Harbor — a workflow skill that reverse-engineers a public website's design primitives into project-local starter token files: run the `extract-design-system` npx tool against a URL, review the normalized output (likely colors, fonts, spacing, radius, shadow scales), then generate `design-system/tokens.json` and `tokens.css`. By @arvindrk, listed here with credit to its creator. Honest caveats: extraction only, not pixel-perfect reproduction and not a full component library; works on public sites only — results are starter material that need review, not an authoritative design system. Skill Harbor never reviews the code, review it yourself before use.
Version:
Install
Prerequisites: Node.js with npx (the tool installs Playwright's Chromium on first run); a public website URL to extract from Install "Extract Design System" for me. Extract design primitives from a public website and generate starter token files (colors, fonts, spacing, radius, shadows) Repository: https://github.com/arvindrk/extract-design-system 1. Fetch the SKILL.md file for the arvindrk-extract-design-system skill from the repository into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "arvindrk-extract-design-system". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. any accounts, API keys, or CLI tools mentioned in the prerequisites above). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. Never ask me to paste secrets in chat — credentials go through the secure vault or environment variables. If anything looks off, stop and ask me.
Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
