Special-Use Domain Names
This document describes what it means to say that a Domain Name (DNS name) is reserved for special use, when reserving such a name is appropriate, and the procedure for doing so. It establishes an IANA registry for such domain names, and seeds it with entries for some of the already established special domain names.
cloudflare/agent-skills-discovery-rfc
A mechanism for discovering Agent Skills using the .well-known URI path prefix as specified in RFC 8615 for discovering Agent Skills.
Declare and resolve website links for at:// URIs. A demo of the me.byjp.atproto.deeplink lexicons.
ai/nanoid
A tiny (118 bytes), secure, URL-friendly, unique string ID generator for JavaScript
CID (Content IDentifier)
Self-describing content-addressed identifiers for distributed systems
README
This is a browser extension that provides “wormhole” navigation between different AT Protocol/Bluesky services inspired by Dame’s Shortcut. The extension transforms URLs and identifiers from one service to equivalent URLs on other services.

DNS-Anchored Durable Identity for AI Agents (DNSid)
Autonomous software agents are being deployed across enterprise, cloud, and cross-organizational boundaries. These agents negotiate, transact, delegate, and produce work products that persist beyond their own ephemeral runtime. Current standards and initiatives for agent identity collectively address runtime authentication, authorization, lifecycle management, and tool interaction, but a gap remains: a durable, governance-backed identifier that lets a relying party determine and verify the accountable entity behind an agent it encounters, including agents that have since been retired or whose keys have rotated, and attribute past and present work products to that entity. Lifecycle-history verification is governed by the applicable log method and deployment scope. DNSid addresses the accountable layer of identity: the durable ownership anchor that existing agent identity standards do not provide. This document specifies DNSid, a minimal identity primitive that assigns each agent a Fully Qualified Domain Name (FQDN), binds it to an accountable entity identified by a DNS domain under that entity's control, and publishes a structured set of pointers in DNS TXT records to the agent's cryptographic keys, lifecycle log, and operational status. DNSid uses accountable-entity-controlled signatures for record integrity and an abstract append-only lifecycle log for history. It is designed to sit beneath existing identity, authentication, authorization, and agent interaction standards without competing with them. DNSid introduces no new DNS resource record types, opcodes, or response codes, and requires no changes to DNS resolvers, authoritative servers, or the DNS protocol. It applies to any agent that can be assigned an FQDN whose accountable entity can publish verification material; public discoverability of the agent is not required.
Evolution of AI Agent Registry Solutions: Centralized, Enterprise, and Distributed Approaches
Autonomous AI agents now operate across cloud, enterprise, and decentralized domains, creating demand for registry infrastructures that enable trustworthy discovery, capability negotiation, and identity assurance. We analyze five prominent approaches: (1) MCP Registry (centralized publication of mcp.json descriptors), (2) A2A Agent Cards (decentralized self-describing JSON capability manifests), (3) AGNTCY Agent Directory Service (IPFS Kademlia DHT content routing extended for semantic taxonomy-based content discovery, OCI artifact storage, and Sigstore-backed integrity), (4) Microsoft Entra Agent ID (enterprise SaaS directory with policy and zero-trust integration), and (5) NANDA Index AgentFacts (cryptographically verifiable, privacy-preserving fact model with credentialed assertions). Using four evaluation dimensions: security, authentication, scalability, and maintainability, we surface architectural trade-offs between centralized control, enterprise governance, and distributed resilience. We conclude with design recommendations for an emerging Internet of AI Agents requiring verifiable identity, adaptive discovery flows, and interoperable capability semantics.
