Agent Ready Auth Md

Skill: Implement Auth.md Agent Registration Discovery

What This Skill Does

Helps a service publish Auth.md support for agent registration. Use this when a scanner reports the authMd check is failing or when adding the Auth.md standard to an API or application.

Requirements

• Serve /auth.md from the service root as Markdown with an H1 heading that contains auth.md (for example, # auth.md or # Example auth.md).
• Prefer publishing OAuth Protected Resource Metadata at /.well-known/oauth-protected-resource for the resource server.
• Include resource, authorization_servers, scopes_supported, and bearer_methods_supported with header in the PRM document.
• Publish OAuth Authorization Server metadata at each advertised authorization server's /.well-known/oauth-authorization-server URL.
• Include a valid issuer in Authorization Server metadata and ensure it matches the issuer advertised in PRM.
• Add an agent_auth block with skill, register_uri, and at least one complete registration method when Authorization Server metadata is available.
• If OAuth metadata is not available, keep /auth.md self-contained: identify the agent audience, document registration or provisioning endpoint(s), list supported method(s), and explain credential use.

Flow Metadata

• ID-JAG: include identity_types_supported: ["identity_assertion"], identity_assertion.assertion_types_supported with urn:ietf:params:oauth:token-type:id-jag, and credential types. Include revocation_uri and the revocation event in events_supported when supported.
• Verified email: include identity_assertion.assertion_types_supported with verified_email, credential types, and claim_uri.
• Anonymous: include identity_types_supported: ["anonymous"], anonymous.credential_types_supported, and claim_uri.
