Agent-readiness feedback: should mintlify.com expose llms.txt on the main site?

[WillSuo-Github]

I ran MARK's docs profile against https://mintlify.com because Mintlify is directly in the developer-docs-for-AI category.

MARK found the homepage, robots.txt, and sitemap.xml, but it did not detect these public agent-readiness entrypoints on the main domain:

• https://mintlify.com/llms.txt
• https://mintlify.com/llms-full.txt
• https://mintlify.com/.well-known/openapi.json
• https://mintlify.com/.well-known/mcp.json
• https://mintlify.com/.well-known/agent.json

This may be a MARK targeting/profile issue rather than a Mintlify issue. The feedback I am trying to get is narrow:

• Should an agent-readiness audit expect the vendor's own main site to expose llms.txt / capability metadata?
• Or should MARK only expect those files on customer docs domains generated by the platform?
• If the main site should expose them too, is this finding worth fixing, obvious, or wrong?

Local repro, no telemetry:
