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.

~ Server response (TTFB) low impact 871ms (good ≤800, warn ≤1800)

Business impact Slow servers cause agents to time out and move on. Fast response keeps you in the running.

What we measured We time the response (time-to-first-byte) against good (<800ms) / warn (<1800ms) thresholds.

How to fix Use a CDN, caching and an optimized origin to get TTFB under 800ms.

Spec: https://web.dev/ttfb/

~ 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.

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.

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.

Transport & Trust (SEC 1.0.0)

HTTPS, HSTS, CSP, sniffing, referrer and CORS posture. Diagnostic only — this does not affect the CAV score. A security header does not make a page more legible to an agent, so scoring it would reward a CDN toggle that changes nothing an agent can recover. We measure it and say so.

Third-party impact

Wasted JavaScript (by bundle)

Transfer-accurate — each bundle's transfer size × its unused %, ranked by wasted bytes (the biggest code-splitting wins). Unused JS also inflates Token Cost (TC).
