# DNS for AI Discovery (DNS-AID)

DNS-AID publishes agent entry points in DNS itself, so discovery works before a single HTTP request is made and cannot be broken by an HTML change.

## When to use this skill

Use this when a site fails the "DNS for AI Discovery (DNS-AID)" check and you need to implement it.

## Goal

Publish DNS for AI Discovery (DNS-AID) records for DNS-based agent discovery

## Pass criteria

ServiceMode SVCB/HTTPS records or a TXT index exist under the _agents namespace, ideally DNSSEC-signed.

## Implementation

This skill covers the diagnosis. The step-by-step implementation prompt is part
of the paid tier and is served per scan by the API — see https://agent-ready.t0ols.com/llms-full.txt.

## Specifications

- https://datatracker.ietf.org/doc/draft-mozleywilliams-dnsop-dnsaid/

## Verifying

Re-run the scan against the site and confirm the check reports a pass:

    curl -s https://agent-ready.t0ols.com/api/scan \
      -H 'content-type: application/json' \
      -d '{"url":"https://example.com","enabledChecks":["dnsAid"]}'
