The agent-readiness package files, explained
Our agent-readiness files help AI agents that land on your website find and understand your business without changing your theme, existing plugins, or server code, and without a new backend.
The exact package is driven by published standards, working-group proposals, and documented conventions, sized to your site's profile (typically 13 files). Every file below links to a plain-English education page with its origin, who defines or maintains it, and where adoption stands today.
Files are grouped by the four Agent Readiness Score dimensions from your free Pre-Check and dashboard: Discoverability, Content Understanding, Agentic Capabilities, and Permissions and Governance.
Discoverability
robots.txt
Your standard robots file, upgraded with modern AI crawler rules and Cloudflare Content Signals, upserted onto your existing rules and never overwritten.
Learn about robots.txt →sitemap.xml
The map agents follow to discover all your content. Generated only when your site has none; an existing sitemap is scored, referenced, and never clobbered.
Learn about sitemap.xml →llms.txt
The foundational answer key at your website root: a curated, machine-readable overview AI agents read first. Proposed by Jeremy Howard (Answer.AI), now checked by Google Chrome's Lighthouse Agentic Browsing audit.
Learn about llms.txt →.well-known/agent-card.json
A structured capability card in the Agent2Agent protocol format (a standard now backed by 150+ organizations) for static agent-to-agent discovery.
Learn about agent-card.json →Content Understanding
schema.jsonld
Validated Schema.org structured data generated from your actual content and merged with any JSON-LD you already have. Used by more than half of all websites.
Learn about schema.jsonld →llm-info.html
A single canonical briefing page for AI systems, following the AI Info Page convention originated by Amin Foroutan. Agents can read one briefing instead of reconstructing your business from fragments.
Learn about llm-info.html →agenticweb.md
The strategic layer: your brand narrative, capabilities, and a recommended agent reading order, in the Markdown format agents parse best. Our own convention, labeled honestly.
Learn about agenticweb.md →Agentic Capabilities
webmcp-registration.js
An experimental static wrapper for WebMCP, the browser API Google and Microsoft are building so websites can offer structured tools to agents. We ship it and keep the claim scoped to what the file actually does.
Learn about webmcp-registration.js →.well-known/agent-skills/index.json
A static catalog of your business capabilities in the Agent Skills format, the open standard originated by Anthropic and adopted across major AI clients.
Learn about the agent-skills catalog →.well-known/mcp/server-card.json
A static Model Context Protocol server card that prepares your site for MCP discovery, without claiming a live MCP server is installed.
Learn about the MCP server card →.well-known/api-catalog
The IETF-standard well-known URI where agents discover your published APIs, or a valid, honest placeholder stating that no public API is advertised.
Learn about api-catalog →Permissions and Governance
.well-known/agent-permissions.json
A machine-readable permission manifest for AI agents, per the spec published by Oxford, Stanford, and Microsoft researchers. Your rules, published where compliant agents look.
Learn about agent-permissions.json →.well-known/ucp
Your Universal Commerce Protocol profile (the Google-and-Shopify-led open standard for agentic commerce), or a clear no-commerce placeholder for service businesses.
Learn about ucp →Never clobbered: your existing files are safe
Three of these files may already exist on your site, and we treat them with an augment-if-present, create-if-absent, never-clobber rule: `robots.txt` is upserted onto your existing rules, `sitemap.xml` is generated only if you have none, and `schema.jsonld` is merged with your existing structured data. An existing customer file is preserved and built upon, never silently overwritten.
Important boundary
AgentReadyWebsite delivers static files and installation guidance. We do not modify your theme, existing plugins, or server code, create live server-side MCP/A2A/NLWeb/WebMCP endpoints, host your website, rewrite your site's accessibility tree or layout stability, or guarantee traffic and revenue lift. For WordPress websites, our free installer plugin installs your agent-readiness package from WordPress admin after you upload the delivery zip (no FTP required). On other platforms you upload the zip.
How this relates to Google AI Search
Google's guidance on AI features in Search says special AI files, AI-only markup, or llms.txt are not required to appear in AI Overviews or AI Mode, yet that’s what we deliver in our agent-readiness package.
The reason we deliver these files is we leave AI Mode placement and SEO rankings alone. We help AI agents that have already reached your website understand your business and accurately answer questions about what you offer.
See the FAQ for how generative AI search visibility differs from agentic browsing, which is the job we focus on.
How this relates to Google's Chrome Lighthouse Agentic Browsing
Google Chrome's Lighthouse Agentic Browsing category groups four areas: llms.txt presence, WebMCP integration, accessibility tree integrity, and layout stability. The WebMCP area itself has multiple named audits; Lighthouse's expected install pattern is live tool registration on the page, not a static file alone.
llms.txtOur package includes the root-level llms.txt file Chrome's audit looks for.
We include an experimental static webmcp-registration.js wrapper, but do not count WebMCP toward Lighthouse coverage until live registration (declarative form attributes or the browser API) is verified against Chrome's audits.
Accessibility tree integrity depends on your site's existing HTML, labels, and interactive elements.
Cumulative Layout Shift depends on your site's CSS, scripts, images, fonts, and rendering behavior.
