Whether agents can crawl you, find you in the registries and searches they check, and trust what they find.

• ✗Sitemap present & freshrequired0/4

  No valid sitemap found: robots.txt listed 0 Sitemap URL(s), and GET /sitemap.xml returned HTTP 200

  fix → Publish /sitemap.xml, reference it from robots.txt, and include <lastmod> dates so agents can tell what's current. Freshest lastmod seen: none.

  Resolved the sitemap from robots.txt or /sitemap.xml, validated XML, and checked lastmod freshness

  spec ↗report issue
• ◐Brand search discoverabilityrequired2/4

  Search "Expanse" cited expanse.sh (https://wastage.expanse.sh, https://docs.expanse.sh/llms.txt), but search "Expanse infrastructure devops" did not cite your domain

  fix → Your domain doesn't surface when agents search "Expanse infrastructure devops". Strengthen brand pages, structured data, and third-party citations (docs portals, GitHub, directories).

  Ran clean brand-name web searches and checked whether your domain is cited in the results

  report issue
• —MCP registry listingsrecommendedna

  No MCP server detected for this product

  Queried the official MCP registry, Smithery, Glama, and PulseMCP for servers matching your domain

  spec ↗report issue

Whether your robots policy, bot protection, and agent guidance actively admit AI agents instead of blocking them.

• ◐robots.txt present & parseablerequired1/2

  /robots.txt returned HTTP 200 but looks like an HTML page (content-type text/html), not a robots policy

  fix → Serve /robots.txt as plain text with User-agent groups; an HTML error page there is unparseable to crawlers.

  Fetched /robots.txt and validated it parses as a robots policy

  spec ↗report issue
• ✓AI crawler policyrequired5/5

  /robots.txt is unparseable (looks like HTML) — crawlers treat this as no restrictions, so none of the 12 AI crawler user-agents are blocked

  Evaluated robots.txt groups for the major AI agent user-agents (GPTBot, ClaudeBot, PerplexityBot, …)

  report issue
• ✗Content Signals directivesemerging0/2

  /robots.txt is unparseable, so no Content-Signal lines could be read

  fix → Declare Content Signals in robots.txt (e.g. `Content-Signal: search=yes, ai-train=no`) to express AI usage preferences machine-readably.

  Looked for Content-Signal lines in robots.txt

  spec ↗report issue
• ✓Agent user-agent paritybetarequired4/4

  All three UAs get HTTP 200; bot bodies are ClaudeBot 100%, GPTBot 100% of the browser response (44517 bytes)

  Compared responses served to browser and AI-agent user-agents (informational while in beta)

  report issue
• ✗agents.mdrecommended0/3

  No agents.md: https://expanse.sh/agents.md → HTTP 200, https://expanse.sh/AGENTS.md → HTTP 200

  fix → Add /agents.md: what agents may do on your site, key URLs, auth, rate limits, and who to contact.

  Fetched /agents.md and checked for substantive agent guidance

  spec ↗report issue

Whether your pages carry machine-readable identity: structured data, llms.txt, clear copy an agent can quote.

• ✓Homepage states what you arerequired3/3

  Homepage clarity rated 5/5 — an agent can confidently say what this company does (model's one-sentence read: "Expanse provides an intelligence layer for HPC and GPU clusters that predicts resource fit and failure risk to unlock hidden capacity and increase throughput without additional hardware.")

  An LLM read your homepage as an agent would and rated how confidently it could say what you do

  report issue
• ✓OpenGraph / social metadatarecommended2/2

  Homepage has og:title, og:description, and og:image (twitter:card="summary_large_image" present)

  Parsed homepage og:title / og:description / og:image and twitter:card meta tags

  spec ↗report issue
• ✗llms.txtrecommended0/4

  /llms.txt returned HTML (content-type text/html), not markdown

  fix → Serve /llms.txt as plain markdown — an HTML page there is a routing catch-all, not an llms.txt.

  Fetched /llms.txt and validated it against the llmstxt.org shape (H1, summary, curated links)

  spec ↗report issue
• ✗llms-full.txtbonusrecommended0/2

  /llms-full.txt returned HTML (content-type text/html), not markdown

  fix → Serve /llms-full.txt as plain markdown, not an HTML page.

  Fetched /llms-full.txt and checked for substantial inline markdown content

  spec ↗report issue
• ✗JSON-LD structured datarequired0/4

  No application/ld+json blocks found on homepage and pricing page

  fix → Embed Organization + WebSite JSON-LD on your homepage (name, url, logo, sameAs) and Product/Offer JSON-LD on pricing.

  Extracted and validated application/ld+json blocks on the homepage and pricing page

  spec ↗report issue
• ✓Markdown content negotiationrecommended3/3

  https://docs.expanse.sh/ returns markdown for `Accept: text/markdown` (content-type text/markdown)

  Requested key pages with Accept: text/markdown and probed .md twin URLs

Whether the artifacts an agent needs to build on you — docs, API specs, SDKs, MCP servers — exist and are findable.

• —Developer resource discoverabilityrecommendedna

  No public API detected

  Searched for your brand with developer-keyword suffixes and checked which official resources are cited

  report issue
• —OpenAPI spec discoverablerequiredna

• ✓Docs discoverablerequired4/4

  Docs found at https://docs.expanse.sh/ (via homepage link, 2010 chars of readable text)

  Followed homepage nav/footer links and probed /docs, /developers, docs.{domain}

• ✗MCP server discoveryrequired0/5

  No MCP evidence found: probed /.well-known/mcp/server-card.json, /.well-known/mcp.json, /mcp.json and scanned llms.txt, agents.md, and docs for endpoints or install commands

  fix → Publish /.well-known/mcp/server-card.json describing your MCP endpoint so agents can autodiscover it. Evidence found: none.

  Probed /.well-known/mcp/server-card.json, mcp.json, and docs mentions for an MCP endpoint

  spec ↗report issue

Whether your specs, docs, and tools are complete and descriptive enough for an agent to use them without guessing.

• —OpenAPI validity & qualityrecommendedna

  No public developer API detected — API checks don't apply

  Linted the spec: descriptions, operationIds, securitySchemes, servers

  report issue
• ◐Docs qualityrecommended2.3/3

  Docs at https://docs.expanse.sh/ scored clarity 4/5, completeness 3/5, runnable examples 5/5, agent-friendliness 3/5 (mean 3.8/5)

  fix → Docs scored 3/5 on completeness. The documentation provides commands for installing the CLI and registering a compute, but it does not provide a clear, direct path for an agent to obtain the necessary API key without human intervention via the console.

  An LLM rated your docs for clarity, completeness, runnable examples, and agent-friendliness

  report issue
• ✓Quickstart / getting startedrecommended2/2

  Quickstart found: https://docs.expanse.org.uk/quickstart (linked from https://docs.expanse.sh/) returns 200 with a code block

  Looked for a quickstart/getting-started guide containing code blocks

Whether pricing is discoverable and machine-readable, and whether you support agent payment protocols.

• ◐Pricing discoverablerequired2.5/5

  Pricing page found at https://expanse.sh/pricing (via path probe) but no legible price signals in 0 chars of page text — no currency amounts, "per month"/"/mo", or "free plan" terms (reads as contact-sales only).

  fix → Add literal plan prices to https://expanse.sh/pricing; 'Contact sales'-only pricing means agents can't complete a purchase evaluation.

  Followed nav/footer links and probed /pricing for a page with legible price signals

  report issue
• ✗Machine-readable pricingrecommended0/5

  No pricing plans could be extracted from https://expanse.sh/pricing (extraction confidence 0.00); no Offer JSON-LD on the page.

  fix → Add Offer JSON-LD per plan (name, price, priceCurrency, billing period) to https://expanse.sh/pricing so pricing parses without inference.

  Looked for Offer JSON-LD, then had an LLM attempt structured extraction of your plans

  spec ↗report issue
• ✗x402 payment supportbonusrecommended0/2

  /.well-known/x402 returned HTTP 200 but not JSON. No x402 support detected (bonus check — absence costs nothing).

  fix → Support x402: serve payment requirements at /.well-known/x402, or answer unauthenticated API calls with HTTP 402 plus an x402 payment-requirements payload (x402Version, accepts[]).

  Probed /.well-known/x402 and API endpoints for HTTP 402 payment-required envelopes
