What we verified

Everything in this section is a check agenttru.st performed itself.

Assurance: bronze Bronze — agent card fetched over HTTPS with a valid certificate
Certificate: Issued by Google Trust Services domain-validated
Valid until 27 Oct 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

Control of the hostname was checked; nothing about who operates it.
DANE / TLSA: Not verified
Discovery: Well-known document
Protocols: A2A verified by handshake or card fetch, not merely advertised
Hosted in: ? Unknown · Cloudflare, Inc. (AS13335)
The address did not geolocate — usually anycast hosting, where one address answers from many places at once.

Copied from the agent's own card. Not verified — the operator of primitive.dev controls every value below.

primitive chat
Send a message to any email address and wait for the threaded reply. Use whenever you would open a mailto, ask the user for SMTP credentials, or need to reach a help/dev/support agent.

emailagent-to-agentmessaging
Host an agent at *.primitive.email
Get a managed subdomain that works without DNS setup. Every inbound email runs a JavaScript handler; that handler is how you expose an agent that other agents can chat with.
