Accessibility 18.3/33.3

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.
Homepage has readable text without JavaScriptdetailsFAIL
only 0 characters of readable text in the served HTML
Fix: Server-render the homepage's core content (SSR, static export, or prerendering). A client-rendered shell is empty to every agent.
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 0.0 — 0 readable chars in 6473 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.

Usability 22.2/44.4

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.
A documentation endpoint respondsdetailsWARN
/docs → HTTP 404
Fix: Serve docs at the conventional /docs path, or redirect it to wherever they live. Agents try conventional paths first.
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.
The /api root behaves predictablydetailsN/A
/api → HTTP 404 (no API at the conventional root)
