Who it is forA designer or developer who wants an honest, evidence-based review of a live site before showing it to a client or submitting it.
The problemOpinions about a site's design, speed and accessibility are hard to compare, and most reviews do not cite evidence.
The outcomeA .jury/ folder with a scorecard.md, screenshots and reports, where every number cites a screenshot or measurement, and fixes ranked by how much score they would gain.
What you need first
- Node 22.20+ for the skills CLI (helper scripts need Node 20+)
- An agent that supports skills, such as Claude Code, Codex, Cursor or Gemini CLI
- A model that can read images, so the QA loop can check its own screenshots
- Playwright and a Chromium browser (the skills install them when needed)
- A Vercel, Netlify or Cloudflare account only if you want the site deployed
Steps
- Run
npx skills add juliobsz/skills -gin a terminal. - Open a new agent session so it loads the skill.
- Type
/jury https://your-site.comwith the URL of the live site. - Open .jury/scorecard.md and read the ranked fix list first.
- Check the jury estimate band against the critic score before you act on it.
Prompt for your agent
Using the juliobsz/skills repo, run the /jury skill on <target URL>. Expect a .jury/scorecard.md file with screenshots, Core Web Vitals measurements and a ranked fix list. Verify that each score in the scorecard links to a screenshot or measurement in the .jury folder.
Caveat. The jury estimate rests on two winning sites and is not affiliated with Awwwards, and pages behind a login cannot be scored.
