Agent Passport Profiles

Purpose

An Agent Passport Profile describes the kind of agent being issued, not the minted Agent Passport itself.

This is useful when you want a public catalog or Agent Registry that answers questions like:

What class of agent is this
What capabilities is it expected to have
What restrictions govern it
What proof format or artifact should accompany issuance

Profile vs Passport

Artifact	Role
`Agent Passport Profile`	Reusable issuance recipe or class definition
`Agent Passport™`	Signed credential for one concrete agent instance
`Agent Registry Entry`	Published reference record that may point to a profile, a minted passport proof, or both

Do not collapse these into one object. A profile should remain stable across many issued agents, while a minted passport is instance-specific and revocable.

Use the Vocabulary page for the canonical public terms used across this site.

Suggested Core Fields

These fields are a practical starting point for profile publication:

profile_id
display_name
subject_type
agent_class
issuer
default_name
realm
capabilities
restrictions
endorsements
lifecycle
proof

Example

{
  "profile_id": "hermes.assistant.v1",
  "display_name": "Hermes Agent",
  "subject_type": "agent",
  "agent_class": "assistant",
  "issuer": "passportalliance.org",
  "default_name": "Herman",
  "realm": "passportalliance.org",
  "capabilities": [
    "communicate.user",
    "present.passport",
    "emit.signed_actions"
  ],
  "restrictions": [
    "no_secret_exfiltration",
    "must_emit_audit_events"
  ],
  "endorsements": [
    "passportalliance.reference-agent"
  ],
  "lifecycle": {
    "revocable": true,
    "renewal_required": true
  },
  "proof": {
    "format": "APIS-v2.1",
    "artifact_required": true
  }
}

Registry Pattern

A future Agent Registry can be layered cleanly:

Signed issuer registry
Published profile catalog
Optional agent reference entries with proof artifacts

This keeps the public site useful even before a fully dynamic registry service exists.

Current Reference Milestone

APIS v2.1 includes a verified reference proof for Herman, the Hermes Agent, as the first minted Agent Passport milestone. The website can act as the publication surface for profile definitions, proof artifacts, and later registry records without treating every profile as an already-live credential.
