Why this is unscored

Content available to the tested client

Raw content extractability

5.6/8 ptsUseful
What we found

Substantial visible text (7,271 chars) is readable without JavaScript on at least one probed page.

How this affects the score

These are recorded points before the total is normalized to 100.

When this matters

Public pages; distinguish HTTP and browser clients

Critical content available in the response is a direct prerequisite for the tested client. An extraction ratio alone does not prove that the needed facts were captured.

UnscoredNot observed
What we found

No crawl-cost signals found (no sitemap URL inventory or Crawl-delay directive).

Why this is unscored

Useful context, outside the readiness score. Adoption, payment support and retrieval cost are not readiness quality by themselves.

When this matters

Measured retrieval path

Tokens, bytes and elapsed time explain retrieval cost and tradeoffs. They are context and do not affect the readiness score.

UnscoredObserved
What we found

A substantive first-hop page exposed another static same-site content link, but sampled second-hop pages were not substantive.

Why this is unscored

Measured, but not yet weighted. It adds no points and its absence subtracts none. Scoring requires calibration of reliability, applicability and overlap with existing checks.

When this matters

Sites with linked public content

Bounded path traversal can explain missing content. Absolute clicks from the homepage is not a validated universal quality scale.

What we found

All 5 agent crawler probes passed. ChatGPT-User=200, ClaudeBot=200, Google-Extended=200, PerplexityBot=200, DeepSeekBot=200

Why this is unscored

A limited scanner observation, not proof of access from real agent infrastructure. It remains unscored until the probe can support that claim.

When this matters

Named client and network context; publisher-permitted retrieval

Current probes identify as HonestClaw with agent-token markers. They cannot verify real vendor access. A bot-protection vendor name alone is not a failure.

An emerging convention, not a universal requirement. It adds no points and its absence subtracts none. Adoption and reliable testing must justify any future weight.

When this matters

Detected emerging authentication scheme

An auth.md file is one possible guide. Reachable metadata and bounded simulation are not proof that credentials can be issued successfully.

Evidence basis

These sources inform the check. They do not validate our exact point weights.
