Discovery 20.1/22.2

API reference linked from the homepagedetailsWARN
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.

title is 89 characters (truncated in most surfaces)
Fix: Trim the <title> to 70 characters or fewer so it is not cut off.
Canonical URL declareddetailsPASS
https://planetscale.com

registry lookup not implemented in v1 — excluded from the score rather than guessed

Accessibility 32.9/33.3

llms-full.txt is publisheddetailsWARN
/llms-full.txt not served

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)
