What is fat-agent-skill?

FAT Agent is a Claude AI plugin that automates post-launch QA for websites, auditing live URLs across SEO essentials, security headers, accessibility, performance, availability, content, and analytics tracking. Tell Claude "run FAT agent on mysite.com" or use the /fat-audit slash command, and it gathers context on your stack (Next.js, WordPress, etc.) and hosting (Vercel, Netlify), then delivers a prioritized punch list with tailored code fixes and re-tests after redeploy. Built in Python, it also offers standalone scripts to analyze HTML, calculate scores, and generate embeddable SVG badges showing your FAT score.

Why is it gaining traction?

Unlike generic Lighthouse runs or manual checklists, FAT Agent integrates directly into Claude conversations for conversational fixes customized to your framework and platform, covering partial accessibility checks via targeted questions and detecting analytics like GA4 or Plausible. It stands out with FAT score badges for READMEs (SEO 95, A11y 82) and platform-agnostic audits—no setup beyond a plugin install. Developers hook on the post-deploy trigger phrases like "I just deployed—is everything working?" that kick off full QA without leaving chat.

Who should use this?

Frontend devs and indie hackers deploying static sites to Vercel or Netlify who skip QA until SEO drops or accessibility complaints hit. SEO agents auditing client landing pages for OG tags, hreflang, or mixed content. Full-stack teams on Next.js, Astro, or WordPress needing quick security header checks and performance budgets without spinning up CI tools.

Verdict

Grab it if you're deep in Claude Code—installs in one command, docs cover every setup, and 200+ tests back the analyzer. At 10 stars and 1.0% credibility, it's early but mature enough for real audits; extend with your own references for fat agent twitch streams or fat agent valorant sites emphasizing accessibility and agent-led QA.
