No useful agent discovery Link headers were found.

Link headers let automated clients discover API catalogs, documentation, and machine-readable alternates without parsing page markup first.

No MCP server card was found at current, transitional, or linked discovery paths.

MCP server cards give agents a stable, public pre-connection discovery surface for server identity, remote transports, protocol compatibility, and safe routing without guessing endpoints.

No WebMCP surface was found to probe.

WebMCP gives agents structured page and browser tool hints so they can understand actions without relying only on screen scraping.

No explicit User-agent rules were found for major AI crawler tokens.

AI crawler product tokens have different meanings. Explicit robots.txt groups make training, search, and retrieval access policy auditable for compliant crawler operators.

/llms.txt was not found or could not be fetched.

llms.txt is an emerging Markdown convention for giving language-model clients curated context and links before they crawl broadly. Broken, private, or low-signal links make the file much less useful even when it exists.

No Organization or Organization subtype was found in Schema.org structured data. No WebSite entity was found in Schema.org structured data. Missing identity field(s): Organization.name, Organization.url, WebSite.name, WebSite.url. WebSite.publisher is missing. Organization schema is missing logo and sameAs or public contact evidence.

Organization and WebSite schema help agents identify the publisher, canonical site identity, logo, and related profiles for attribution.

No JSON-LD, Microdata, or RDFa structured data was found.

Structured data gives agents explicit entities, relationships, and page meaning that are harder to infer reliably from visual layout alone.

The site appears to support login, signup, account access, or credentials but does not publish /auth.md.

Human login and signup flows are often opaque to agents. Auth.md gives automated clients a stable registration contract instead of forcing them to scrape docs, automate browser forms, or guess credential flows.

Generic authentication signals were found, but no OAuth/OIDC discovery signal was detected.

OAuth and OIDC discovery let agents and API clients find authorization, token, and key endpoints programmatically instead of scraping login pages or guessing provider setup.

Generic authentication signals were found, but no OAuth Protected Resource metadata signal was detected.

Protected-resource metadata tells agents which API/resource is locked, which authorization servers can issue tokens for it, and how a 401 challenge maps back to the correct resource.

Best candidate returned Content-Type "text/html; charset=UTF-8" instead of text/markdown.

Markdown representations give agents a cleaner page form while preserving normal HTML for browsers and cache-safe representation handling.

Referrer-Policy header is missing.

Referrer-Policy controls how much URL context is sent to other origins, limiting accidental leakage of paths, queries, and identifiers.

No A2A Agent Card was found at the current, legacy, or fallback discovery paths.

A2A Agent Cards provide protocol-specific discovery for agent identity, skills, input and output modes, transport bindings, capabilities, and security requirements. Legacy A2A also used /.well-known/agent.json, so scanners must classify the card shape before reporting readiness.

No Agent Skills discovery index was found at the canonical or legacy path.

An Agent Skills index lets agents discover task-specific instructions through a small trusted index, then verify and load only the skill artifacts they need.

No Wildcard-style agents.json file was found.

Wildcard agents.json gives agents workflow-level context beyond plain OpenAPI, including flows, links, examples, and API action structure. It is an emerging OpenAPI-adjacent proposal, so scanners should validate the contract shape without treating it as an A2A or IETF standard.

No Content-Usage or Content-Signal declarations were found.

Content usage preference signals communicate intended downstream AI use separately from robots.txt crawl permission. They can express training and search preferences for compliant systems without replacing access-control rules.

No DNS-AID HTTPS/SVCB records were found under _agents.

DNS-AID lets agents discover index, A2A, and other agent entrypoints before fetching HTTP metadata. HTTPS/SVCB records provide the service-binding substrate, while DNSSEC can authenticate the discovery answer when available.

No RSL declarations were found.

Really Simple Licensing is an emerging rights-expression layer for communicating content usage and licensing terms separately from robots.txt crawl permission.

No TDMRep declaration was found at /.well-known/tdmrep.json.

TDMRep is a W3C Community Group protocol and IANA-registered well-known URI for declaring text and data mining reservation policy on applicable content.

Applicable HTML response is missing an enforcing Content-Security-Policy header.

Content Security Policy reduces the impact of injection bugs by limiting where scripts, styles, frames, forms, and other browser resources can load or execute.

No valid X-Frame-Options fallback is present.

Frame protection blocks hostile sites from embedding pages in deceptive frames, reducing clickjacking and UI redressing risk.

HTTPS response is missing Strict-Transport-Security.

HSTS tells browsers to keep using HTTPS after the first secure visit, reducing downgrade, SSL-stripping, and mixed-transport risk for repeat users.

No evidence-backed, citation-length explanatory paragraph was found.

Generative answer systems work best with visible, self-contained, evidence-backed content, clear entities, trustworthy attribution, structured page sections, and crawler-accessible HTML. These signals improve machine understanding even though they do not guarantee AI citations.

Browser-loadable response is missing X-Content-Type-Options.

X-Content-Type-Options tells browsers to trust declared media types instead of sniffing content, reducing the risk that mislabeled files execute as active content.

Semantic HTML is incomplete: expected exactly one visible main landmark, found 0; invalid h1 structure (visible h1 count 2); skipped or empty headings; 4 images missing alt attributes; 4 image alt text quality issues.

Semantic HTML gives browsers, assistive technology, search systems, and agents reliable landmarks, headings, controls, form semantics, and image context.

No named author or publisher identity could be extracted.

Author attribution helps agents cite content responsibly, assess source credibility, and distinguish editorial pages from anonymous marketing copy.

8 section(s) bury or omit a concise opening answer.
