Website

**Judgment:** This skill is well-suited for building or reviewing small to medium, mostly static websites that need to be fast, accessible, and SEO-friendly. It encodes a solid, practical checklist of modern frontend best practices. **Strengths & advantages:** - Covers key performance levers (images, render-blocking CSS, third-party scripts, fonts) in line with Lighthouse-style optimization. - Strong accessibility baseline: alt text, labels, contrast, keyboard navigation, heading hierarchy, semantic HTML. - Encourages mobile-first, responsive design and semantic structure, which helps with SEO and maintainability. - Includes pragmatic operational considerations: favicons, HTTP→HTTPS issues, Open Graph tags, sitemaps, uptime monitoring. **Risks & limitations:** - Geared toward conventional static pages; may not fully address complex web apps, advanced JS frameworks, or bespoke design systems. - Cannot replace real-device testing, full accessibility audits, or comprehensive SEO strategy; human review remains necessary. - Framework-, CMS-, or backend-specific concerns (routing, auth, state, security headers, caching/CDN strategy) are only indirectly covered. **Recommended scenarios:** - Generating or polishing marketing sites, landing pages, and content sites where performance and accessibility matter. - Using as a checklist during code review or pre-launch QA of frontends. - Training developers on modern HTML/CSS/UX best practices and avoiding common production pitfalls.
