Score: 9.2/10
Tested: Jul 14, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 18, 2026 · 89e3f4f

Skill-guided pre-launch package added llms.txt, agent.json, an A2A agent-card.json, and the 2025 Content-Signal robots.txt directive that a baseline (unguided) pass skipped entirely — genuinely current agent-readiness practice, not repackaged classic-SEO boilerplate.

What SEO & LLMO does

A single comprehensive SKILL.md that walks through JSON-LD structured data (Organization/Product/SoftwareApplication/FAQPage), robots.txt with AI-crawler and Content-Signal directives, llms.txt/llms-full.txt, agent-readiness files (agent.json, A2A agent-card.json, mcp.json, pricing.md), Open Graph/meta tags, and Core Web Vitals/SPA fixes. Triggers before any site launch or SEO request, and even implicitly when scaffolding a new public-facing site.
