Curated by Skill Harbor — an evidence-led web quality audit orchestrator: establish the audit target, collect a live baseline, then review Performance (Core Web Vitals — LCP < 2.5s, INP < 200ms, CLS < 0.1), Accessibility (WCAG AA: alt text, contrast, keyboard, focus), SEO, Best Practices, and Agentic Browsing — keeping measured findings separate from code-only hypotheses, categorizing by user impact, and re-running checks after fixes. Routing: live browser traces or Lighthouse audits where available, Lighthouse CLI/PageSpeed Insights as fallback, plus a static analyzer as a fast smoke test (never a substitute for a rendered-page audit). Partly overlaps the already-listed addyosmani-performance — the Performance section points at that skill's measurement workflow — but this is a broader audit orchestrator, not a duplicate: five categories, source inspection, and fix verification instead of performance alone. By @addyosmani, listed here with credit to its creator. Honest caveats: it audits — it doesn't fix; some findings will need field data or human validation; best run with browser tooling (Chrome DevTools MCP or Lighthouse CLI) available. Skill Harbor never reviews the code, review it yourself before use.

Install
Prerequisites: none beyond a working agent; browser tooling (Chrome DevTools MCP or Lighthouse CLI) recommended for the full audit Install "Web Quality Audit" for me. Run an evidence-led web quality audit: performance, accessibility, SEO, best practices Repository: https://github.com/addyosmani/web-quality-skills/blob/main/skills/web-quality-audit/SKILL.md 1. Fetch the SKILL.md file for the addyosmani-web-quality-audit 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 "addyosmani-web-quality-audit". 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.
