# Skill: Publish DNS-AID Discovery Records (RFC 9460)

> **Standard:** RFC 9460
> **Category:** DISCOVERABILITY
> **Classification:** SPECIFICATION_AND_GUIDE

## Overview
Configure DNS-AID SVCB/TXT records enabling autonomous agents to discover capabilities at the network transport layer via DNS.

## Learning Objectives
1. Publish _index._agents TXT record on the domain zone apex.
2. Advertise supported agent protocols and version digests.

## Prerequisites
- Authoritative DNS management with DNSSEC enabled

## Implementation & Execution Guide

### Step 1: Create Zone Apex TXT Record
Publish the standardized DNS-AID record.

```http
_index._agents.tinycto.tv. IN TXT "v=aid1; mcp=https://tinycto.tv/api/mcp/sse; skills=https://tinycto.tv/.well-known/agent-skills/index.json"
```

## Architectural Takeaway
DNS-AID eliminates HTTP discovery roundtrips by resolving machine capabilities directly during initial DNS lookup.
