Overview
# 🍔 FAT Agent with Superpowers — Fix, Audit, Test
 [](https://github.com/spruikco/fat-agent-skill/actions/workflows/ci.yml) [](https://www.python.org/downloads/) []() [](LICENSE)
**A modular Claude plugin that acts as your post-launch QA engineer.**
FAT Agent systematically audits deployed websites across SEO, security, accessibility, performance, local SEO, e-commerce, email deliverability, internationalisation, DNS infrastructure, and more — then walks you through fixing every issue found.
---
## What It Does
After you deploy a site, say **"run FAT agent"** and it will:
1. **Gather context** — Asks about your site, stack, and critical user flows 2. **Auto-detect modules** — Analyses your HTML for e-commerce, local business, i18n, and email signals 3. **Audit** — Runs core + detected modules against your live URL 4. **Crawl site-wide** — Concurrent crawl into SQLite (pages + full link graph) for the issues single pages can't show: broken internal links, duplicate titles/content, orphan pages 5. **Report** — Generates a prioritised punch list, HTML dashboard, and shareable reports 6. **Fix** — Offers to generate code fixes for every issue found 7. **Re-test** — After you redeploy, verifies the fixes are live (the punch list persists to disk and auto-resolves)
### Core Modules (always enabled)
