MarketCore Editorial Review
A smart specialization: most SEO skills handle strategy but FAT Agent handles post-launch QA. The combination of SEO + security + accessibility + performance in one audit skill fills a real gap — these are exactly the checks that get skipped after a landing page launches under deadline pressure.
Best For
- Post-launch checklist for marketing landing pages before traffic is sent
- Catch broken links, missing meta tags, and security header regressions after CMS updates
- Accessibility audit for compliance and SEO benefit on campaign microsites
Code Quality
Clean implementation with a clear scope boundary. The audit checklist is comprehensive and the severity ratings are useful for prioritization. Well-suited for devs on marketing teams rather than pure marketers.
Limitations
More dev-oriented than marketer-oriented — requires comfort with terminal and technical audit output. Not a replacement for dedicated performance tools like Lighthouse. Limited documentation for non-technical users.
