Needs attention

Auth.md Agent Registration

Failed check
01

Issue

auth.md response did not match Auth.md v1 agent registration guidance. Content-Type "text/html; charset=utf-8" is not Markdown or text/plain; missing registration instructions; missing OAuth Protected Resource Metadata discovery guidance; missing OAuth authorization-server metadata guidance; missing Auth.md credential type guidance; missing agent_verified/user_claimed or claim ceremony guidance; missing credential usage, expiry, error, or revocation guidance.

Details

02

Why it matters

Human login and signup flows are often opaque to agents. Auth.md gives automated clients a stable registration contract instead of forcing them to scrape docs, automate browser forms, or guess credential flows.
