Discovery 10.6/22.2

robots.txt allows agent crawlersdetailsFAIL
robots.txt blocks ClaudeBot, GPTBot, Google-Extended from /
Fix: Remove the Disallow rules for ClaudeBot, GPTBot, Google-Extended in /robots.txt, or narrow them to the paths you really want kept out. Blocking these crawlers is the single most effective way to make your product invisible to AI agents.
sitemap.xml exists and parsesdetailsFAIL
sitemap.xml not served (HTTP 404)
Fix: Publish /sitemap.xml listing your public pages, and reference it from robots.txt with a `Sitemap:` line.
API reference linked from the homepagedetailsWARN

<a href="https://www.vorza.dev/score/lens.dev"><img src="https://www.vorza.dev/api/badge/lens.dev" alt="agent readiness score" /></a>

no link to an API reference in the homepage HTML

Fix: If you have an API, link its reference from the homepage. If you don't, this check is safe to ignore.

Canonical URL declareddetailsWARN

no <link rel="canonical">

Fix: Add <link rel="canonical"> to the homepage so agents and crawlers converge on one URL for this page.

Homepage has a meta descriptiondetailsWARN

description is only 44 characters

Fix: Expand the meta description to at least 50 characters.

Homepage has a descriptive titledetailsWARN

title is only 4 characters: 'Lens'

Fix: Expand the <title> to 10–70 characters naming the product and what it does.

robots.txt points at the sitemapdetailsWARN

robots.txt does not reference a sitemap

Fix: Add `Sitemap: https://<domain>/sitemap.xml` to /robots.txt so crawlers find it without guessing.

Documentation linked from the homepagedetailsPASS

4 docs link(s), e.g. /docs

Open Graph tags presentdetailsPASS

Accessibility 25.7/33.3

llms.txt is publisheddetailsFAIL
/llms.txt not served (HTTP 404)
Fix: Publish /llms.txt: a plain-markdown index that tells an agent what this product is and where the authoritative docs live. It is the cheapest high-leverage file you can add.
Structured data (JSON-LD) on the homepagedetailsWARN
no JSON-LD blocks on the homepage
Fix: Add a JSON-LD block (schema.org Organization or SoftwareApplication) so agents get your name, description and links as data rather than prose.
llms-full.txt is publisheddetailsWARN
/llms-full.txt not served
Fix: Optional but cheap: publish /llms-full.txt with your docs inlined as one markdown file, so an agent can read everything in a single fetch.
Serves markdown when asked for itdetailsWARN
Accept: text/markdown → text/html; charset=utf-8
Fix: Optional but increasingly expected: honour `Accept: text/markdown` by serving a markdown rendering of the page, so agents skip HTML parsing entirely.
Content-to-markup ratio is reasonabledetailsWARN
ratio 0.0093 — 2062 readable chars in 222663 bytes of HTML
Fix: Most of what you serve is markup and inline script rather than content. Reduce inline payloads or server-render more text so the signal-to-noise ratio favours readers.
Docs are readable without JavaScriptdetailsPASS
2515 characters of text at /docs
Homepage responds to an agent requestdetailsPASS
HTTP 200 for / (agent UA)
Served over HTTPSdetailsPASS
https://lens.xyz/
Same response for agents and browsersdetailsPASS
both User-Agents got HTTP 200
Homepage has readable text without JavaScriptdetailsPASS
2062 characters of text in the served HTML
No long redirect chain on the homepagedetailsPASS
1 redirect(s)
Links in llms.txt resolvedetailsN/A
no llms.txt
llms.txt is structured markdowndetailsN/A
no llms.txt to parse

Usability 25.7/44.4

agents.md is publisheddetailsWARN
/agents.md not served (HTTP 404)
Fix: Publish /agents.md: what an agent may do here, which endpoints matter, auth requirements, and rate limits. It is the agent-facing counterpart to a README.
Errors are machine-readabledetailsWARN
404 returns HTML, not a machine-readable body
Fix: Content-negotiate your errors: return a JSON body with a stable `code` (and a `next_action` where recovery exists) to clients that ask for JSON.
OpenAPI document publisheddetailsWARN
/openapi.json not served (HTTP 404)
Fix: If you have an HTTP API, publish its OpenAPI document at a predictable path (/openapi.json). It is the difference between an agent reading your contract and an agent guessing it. If you have no HTTP API, ignore this.
.well-known/mcp.json advertises an MCP serverdetailsWARN
/.well-known/mcp.json not served (HTTP 404)
Fix: If you run an MCP server, advertise it at /.well-known/mcp.json so agents discover it without being told its URL.
A documentation endpoint respondsdetailsPASS
/docs → HTTP 200
The /api root behaves predictablydetailsN/A
/api → HTTP 404 (no API at the conventional root)
MCP server completes the initialize handshakedetailsN/A
no MCP endpoint found to probe (none in the input URL and none advertised at /.well-known/mcp.json)

no listed MCP tools to inspect
Every MCP tool has a descriptiondetailsN/A
