# auth.md

You are an agent. This service supports agentic registration for Dmitri Derevjanko's portfolio.

- Resource server: `https://dmitriderevjanko.com`
- Authorization server: `https://dmitriderevjanko.com`

Public portfolio resources are readable without a token. Private integration access uses an anonymous registration flow followed by a manual contact claim ceremony.

## 1. Discover

### 1a. Protected Resource Metadata

```http
GET /.well-known/oauth-protected-resource HTTP/1.1
Host: dmitriderevjanko.com
Accept: application/json
```

Read:

- `resource`
- `authorization_servers`
- `scopes_supported`
- `bearer_methods_supported`

### 1b. Authorization Server Metadata

```http
GET /.well-known/oauth-authorization-server HTTP/1.1
Host: dmitriderevjanko.com
Accept: application/json
```

Read:

- `issuer`

- `grant_types_supported`
- `agent_auth.skill`
- `agent_auth.register_uri`
- `agent_auth.claim_uri`
- `agent_auth.identity_types_supported`
- `agent_auth.anonymous.credential_types_supported`

## 2. Pick a method

Use this decision tree:

- If the user only needs public portfolio information → read public resources directly, no registration required.
- If the user needs private integration access and no verified identity provider is available → use `anonymous`.
- If the user can verify identity through LinkedIn/email follow-up → complete the claim ceremony after anonymous registration.

Supported registration type for this service:

- `anonymous`

## 3. Register

### anonymous

Request:

```http
POST /api/agent/auth HTTP/1.1
Host: dmitriderevjanko.com
Content-Type: application/json

{
  "type": "anonymous",
  "requested_credential_type": "contact_request"
}
```

Success response:

```json
{
  "type": "anonymous",
  "status": "claim_required",
  "scopes": ["portfolio.read", "profile.read", "discovery.read"],
  "claim_token": "claim_...",
  "claim": {
    "verification_uri": "https://www.linkedin.com/in/dmitri-derevjanko/",
    "user_code": "CONTACT-DMITRI",
    "instructions": "Ask the user to contact Dmitri by email with workflow details."
  },
  "contact_email": "dmitri.derevjanko02@gmail.com"
}
```

## 4. Claim ceremony

### 4a. Start claim

```http
POST /api/agent/auth/claim HTTP/1.1
Host: dmitriderevjanko.com
Content-Type: application/json

{
  "claim_token": "claim_...",
  "email": "user@example.com"
}
```

Pending response:

```json
{
  "status": "authorization_pending",
  "message": "Contact request registered. Dmitri will provision private access manually if appropriate.",
  "contact_email": "dmitri.derevjanko02@gmail.com",
  "verification_uri": "https://www.linkedin.com/in/dmitri-derevjanko/"
}
```

### 4b. Hand off to the user

Tell the user:

1. Open https://www.linkedin.com/in/dmitri-derevjanko/
2. Or email dmitri.derevjanko02@gmail.com
3. Include workflow problem, data sources, desired outcome, and deadline

### 4c. Poll for completion

This portfolio does not issue automated OAuth access tokens. Manual provisioning happens outside the automated flow.

## 5. Use credentials

Public resources require no `Authorization` header.

Supported public scopes:

- `portfolio.read`
- `profile.read`
- `discovery.read`

Example public read:

```http
GET /llms-full.txt HTTP/1.1
Host: dmitriderevjanko.com
Accept: text/plain
```
