What problem does it solve? Websites often go live with SEO, accessibility, and security mistakes that become expensive to fix after indexing and public exposure. This Skill enforces a mandatory pre-flight audit so nothing ships unaudited. ## Core Features & Use Cases - Gate orchestration: Runs existing quality gates first — visual-qa (WCAG AA accessibility, overflow, console errors), security-gate (secrets, TLS, dependencies), and system-design-gate (lockfile, env example, SQL interpolation) — as ship-blockers. - SEO / GEO audit: Applies the vendored claude-seo methodology covering technical SEO, on-page tags, Schema.org JSON-LD, sitemaps, E-E-A-T content signals, image optimization, and GEO/AEO readiness for AI answer engines. - Prioritized launch checklist: Writes findings into LAUNCH-CHECKLIST.md as blocking / should-fix / nice-to-have items and logs the pass in PROJECT-LOG.md. - Use Case: Before pointing a custom domain at a new marketing site, run this audit to catch a missing sitemap, a stray noindex tag, and absent OG images, fix the blocking items, then publish. ## Quick Start Run the pre-publish audit on my production build and give me the prioritized launch checklist before I deploy.
