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.

⚠️ Your page title reads like a navigation menu, so an agent may cite your business as “Charles Schwab | A Modern Approach to Investing and Retirement Planning | Charles Schwab”.
An agent gets the basics but will guess on the gaps. 3/7 applicable facts come from machine-readable structured data.
Metrics
Token Cost breakdown
Where the page's tokens go (≈8,373 across regions). 60% is non-content — chrome and boilerplate an agent pays for. Add landmark roles (main/nav/header/footer) so agents can skip it.

Diagnostics
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.

✗ 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.
# Your Site
> One-line description for AI agents.
## Key pages
- /products — catalog
- /pricing — plans
- /docs — documentationSpec: https://llmstxt.org
~ XML sitemap fresh medium impact Stale (lastmod 2024-08-22T13:47:30-04:00)
Business impact A sitemap is your table of contents for AI crawlers. Without it agents follow homepage links and miss deep pages (products, docs, pricing) — shrinking what they can recommend.
What we measured We fetch /sitemap.xml (and /sitemap_index.xml), confirm valid XML with <loc> entries, and check <lastmod> freshness.
How to fix Generate an XML sitemap of all public pages with current lastmod dates and reference it in robots.txt.
# robots.txt
Sitemap: https://example.com/sitemap.xml~ 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.

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=31536000; includeSubDomains |
| ✅ Content-Security-Policy | policy present, script-src does not allow inline |
| ✅ X-Content-Type-Options | nosniff |
| ⚠️ Referrer-Policy | no referrer-policy header (browser default applies) |
| ✅ CORS exposure | access-control-allow-origin: www.schwab.com |
