What Core Agent Vitals is

Core Agent Vitals (CAV) is the framework — created by Rafael Lopes — for measuring how AI agents read, understand, and act on a web page: what a machine consumer actually recovers, comprehends, and can use.

The six metrics (defined by Rafael Lopes)

CRR — Content Recovery Ratio (good ≥ 0.95)

Meaningful content present in the raw pre-JavaScript HTML divided by the content available after a full render. A client-rendered page can score near zero even when it looks perfect to a person.

SSD — Semantic Signal Density (good ≥ 0.60)

Half the share of tokens that are main content (signal vs. boilerplate noise) plus half the coverage of required structured-data (JSON-LD) fields for the page’s critical entities.

ARR — Action Resolution Rate (good = 1.0)

The share of critical-path actions resolvable through stable accessible-tree locators with zero selector drift. Your ARIA labels are the agent’s API.

TC — Token Cost (good < 4,000)

The cl100k_base token count of the agent representation of the page. A bloated, boilerplate-heavy page burns the agent’s budget before it reaches your content.

TTFUT — Time to First Useful Token (good low / watch)

How fast the first useful token reaches a streaming agent — the latency signal. Timing-based, so a signal to watch rather than a hard gate.

AF — Answer Fidelity (good ≥ 0.95)

The north-star metric: given only the page’s agent representation, an LLM correctly answers canonical per-template questions about it. Measures whether the page is not just recoverable but actually understood.

The 28-day score is the p75 of nightly runs — the stable number to cite. Deterministic metrics (CRR/SSD/TC) show their latest value (they move only when the site changes); timing (TTFUT) and answer-fidelity (AF) are smoothed by 28-day p75 — the same lab-vs-field split Core Web Vitals uses. Synthetic daily measurement, not real-user field data.

medium CRR Content is hidden behind JavaScript

pre-JS raw HTML

Evidence8% of content requires JS · 92% of rendered content recovered (rest is placeholder/wrong)

ImpactA non-rendering agent never sees the JS-injected content.

Effort1–4 h

Fix: Server-render or statically generate the main content so a non-JS agent still receives it; make client rendering a progressive enhancement, not the source of truth.

medium TC 42% of tokens are non-content (boilerplate/chrome)

agent representation — token decomposition

EvidenceToken decomposition: content 58%, chrome 14.9%, boilerplate 5.6%, other 21.6%. Only 58% of the agent's tokens are real content.

ImpactAn agent pays for boilerplate on every request and has less context left for the real content.

Effort30–90 min

Fix: Strip repeated nav/header/footer/cookie chrome from the agent-visible output; wrap content in <main>/<article> so the extractor keeps signal and drops boilerplate.

Issues (7)

✗ robots.txt allows AI bots high impact Blocks: * (all)

Business impact If robots.txt blocks AI crawlers you are invisible to ChatGPT, Claude and Perplexity — they skip you and recommend a competitor instead.

What we measured We read /robots.txt and test it against 16 AI user-agents (GPTBot, ClaudeBot, PerplexityBot, …) for a Disallow that blocks them.

How to fix Allow major AI bots to public content; restrict only private paths (/admin, /api).

Learn how to implement →

User-agent: GPTBot
Allow: /
Disallow: /admin/

Spec: https://platform.openai.com/docs/gptbot

~ No content-blocking cookie wall medium impact Consent platform: onetrust (verify it doesn't block content)

Business impact A consent wall that hides content until a click is invisible to agents — they cannot click 'Accept'.

What we measured We fingerprint OneTrust, Cookiebot, Usercentrics and similar managers and flag content-blocking ones.

How to fix Use an overlay banner that leaves content in the DOM, not a blocking interstitial.

Spec: https://gdpr.eu/cookies/

✗ llms.txt present high impact Absent at /llms.txt and /.well-known/llms.txt

Business impact llms.txt is the robots.txt for AI: it tells agents what your site is, what matters, and where to find it. Without it AI guesses — and guessing means inaccurate recommendations and lost visibility.

What we measured We fetch /llms.txt and /.well-known/llms.txt and validate the spec (H1 title + a one-line blockquote summary). We also note /llms-full.txt (your full content as Markdown).

How to fix Create /llms.txt with a short summary + key pages; optionally /llms-full.txt with full content in Markdown.

Learn how to implement →

# Your Site
> One-line description for AI agents.

## Key pages
- /products — catalog

Spec: https://llmstxt.org

~ No login wall on public content high impact Login signal: please log in

Business impact Public content behind authentication is unreachable to agents (they have no account). Gate only genuinely private material.

What we measured We follow redirects and detect 401/403 and login-form signals on content pages.

How to fix Separate public marketing/docs from authenticated areas; keep public pages reachable without login.

Spec: https://llmstxt.org

~ agents.json discovery low impact Absent (emerging standard)

Business impact agents.json describes what your site can DO for agents (services, endpoints, capabilities) — an emerging discovery standard. Early adopters get native agent integration.

What we measured We check /agents.json and /.well-known/agents.json for a valid configuration.

How to fix Publish /agents.json describing your site's capabilities and actions.

Learn how to implement →

Spec: https://github.com/wild-card-ai/agents-json

~ WebMCP endpoint low impact Absent (emerging standard)

Business impact WebMCP lets agents call actions on your site directly (book, buy, query) instead of scraping the DOM. Early adopters get native AI-agent interoperability.

What we measured We check /.well-known/webmcp and /webmcp.json for a valid actions array.

How to fix Add a WebMCP endpoint exposing your key actions to agents.

Learn how to implement →

Spec: https://webmcp.org

~ API documentation low impact No OpenAPI/Swagger found

Business impact Programmatic agents prefer a typed API. An OpenAPI/Swagger spec lets them integrate without scraping.

What we measured We probe /openapi.json, /swagger.json, /api-docs and /.well-known/openapi.json.

How to fix Publish an OpenAPI spec at a well-known path.
