Declare your namespace.

Agentic infrastructure that does not declare its namespace position is invisible to agents. Declaration is not optional — it is the prior condition for agent-readable presence.

This site publishes specifications and schemas for namespace declarations: AGENTS.md, /.well-known/agent.json, and the cluster manifest format. These are the files agents read before reading anything else. Getting them right is the first step.

The concept behind namespace declarations is defined at semanticnamespace.org. The framework for scoring how well a domain declares its namespace lives at semantic-domains.com. This site is the implementation reference.

Core Declaration Files

• /AGENTS.md Site purpose, role, scope, and crawl policy in human and agent-readable markdown
• /.well-known/agent.json Machine-readable role, capabilities, and cluster cross-references
• /.well-known/namespace-cluster.json Cluster manifest declaring all nodes, roles, and canonical links
• /robots.txt Explicit AI crawler permissions — named per vendor UA string
• /sitemap.xml Valid sitemap ensuring crawler path coverage
