An agent-ready website works for AI agents as reliably as it works for human visitors. LLMs.txt, WebMCP-annotated forms, schema markup optimized for AI citation, and a passing Lighthouse Agentic Browsing score, shipped on every Vibe89 build at no extra charge.
More and more customers are letting AI tools browse and shop on their behalf. Google AI Mode, Gemini, ChatGPT, and Perplexity all need clear signals to understand your business, navigate your site, and cite you accurately. Agent-ready architecture gives them that map, without sacrificing the experience your human customers expect.
A markdown file at your domain root with curated links to the most important pages and one-line descriptions. Parseable by ChatGPT, Gemini, Perplexity, Claude, and other AI systems at inference time. Learn more
Declarative HTML attributes on forms that turn contact, booking, and quote flows into machine-readable tools agents can call directly, instead of guessing which field is which. Learn more
LocalBusiness, Service, FAQ, and industry-specific structured data that feeds Google's generative UI, AI Mode citation engines, and conversational discovery flows.
The same clean navigation path that screen readers use is the path AI agents follow. ADA WCAG 2.1 AA compliance and agent-readiness share the same foundation.
LLMs.txt lives at yourdomain.com/llms.txt. We research your site, curate the pages that matter most, write concise descriptions, and deploy both llms.txt and an expanded llms-full.txt on every Spark-tier build and above.
Chrome’s Lighthouse Agentic Browsing category, shipped in Lighthouse 13.3, audits for its presence directly, so this is a published standard rather than a convention. Worth being precise about the limits: Google Search does not use LLMs.txt as a ranking signal and says so in its own documentation. What the file gives you is a canonical, machine-readable account of your business that agentic tooling can read without inferring it from scraped page text, and a passing mark on an audit your competitors will fail.

WebMCP is a proposed open web standard (Chrome 149 origin trial). It adds toolname, tooldescription, and toolparamdescription attributes to HTML forms, letting browser-based AI agents interact with your contact, booking, and quote forms directly.
Every Vibe89 build ships WebMCP on at least the contact form. Spark and above include annotations on all forms. We test with Chrome's Model Context Tool Inspector before launch.
Added May 2026 to Lighthouse, Google's own tool for scoring a site's speed and quality. This new category checks accessibility tree quality, LLMs.txt presence, and WebMCP integration. Vibe89 targets 90+ on this category on every build, alongside Performance, Accessibility, Best Practices, and SEO.
Clean semantic structure agents and assistive technology both rely on. No overlay widgets, no bolt-on fixes.
Verifies a curated LLMs.txt file exists at the domain root and points to meaningful pages.
Confirms forms expose machine-readable tool metadata so agents can complete actions reliably.
You don't need a full rebuild to get agent-ready. Pick what's missing, we link you to the explainer and the standalone service on every card.
