robots.txt not served (HTTP 404)

Fix: Serve a /robots.txt. Without it, agent crawlers have to guess what they may fetch.

no <link rel="canonical">

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

5 API link(s), e.g. https://api.jina.ai/openapi.json

5 docs link(s), e.g. https://www.elastic.co/docs/explore-analyze/elastic-inference/eis

/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.

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 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.

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.

ratio 0.0167 — 10802 readable chars in 647435 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 not served (HTTP 404) — docs may live on another path or host

no llms.txt

no llms.txt to parse

/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.

/docs → HTTP 404

Fix: Serve docs at the conventional /docs path, or redirect it to wherever they live. Agents try conventional paths first.

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.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 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.

/api → HTTP 404 (no API at the conventional root)

no MCP endpoint found to probe (none in the input URL and none advertised at /.well-known/mcp.json)
