Scored by v3 · source-of-truth hashes: score db860d6ac94e · thresholds e94f8b33e500 — verifiable against the canonical scorer.
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.
An agent is likely to fabricate missing details rather than say “I don’t know”. 0/4 applicable facts come from machine-readable structured data.
Metrics
Token Cost breakdown
Where the page's tokens go (≈21,315 across regions). 54% is non-content — chrome and boilerplate an agent pays for. Add landmark roles (main/nav/header/footer) so agents can skip it.
Final screenshot
Diagnostics
pre-JS raw HTML
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.
agent representation — token decomposition
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.

Agent files & endpoints
Issues (5)
~ 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/
~ Machine-readable prices medium impact No prices found
Business impact When a user asks an agent 'how much does X cost', it needs readable pricing. Hidden, JS-only or 'request a quote' pricing means the agent can't answer — and recommends someone who can.
What we measured We scan the HTML for price patterns and Schema.org Offer/PriceSpecification markup.
How to fix Expose prices (or a starting-from range) in HTML and add Schema.org Offer.
<script type="application/ld+json">{"@type":"Offer","price":"29.90","priceCurrency":"EUR"}</script>Spec: https://schema.org/Offer
~ 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.
~ 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.
Passed audits (7)
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.
Per-header findings (6)
| Header | Evidence |
|---|---|
| ✅ HTTPS | served over HTTPS |
| ✅ HSTS | max-age=15552000 |
| ❌ Content-Security-Policy | no content-security-policy header |
| ❌ X-Content-Type-Options | missing nosniff |
| ⚠️ Referrer-Policy | no referrer-policy header (browser default applies) |
| ➖ CORS exposure | no CORS headers on the document (normal for an HTML page) |

Third-party impact
348 third-party requests · 2275 KiB (47.4% of transfer) · 383 ms main-thread — code an agent must also fetch/run before your content settles. Fewer, lazier third-parties = faster, cheaper agent reads.

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).
