## What it does

This skill covers turning an agent identity into an agent user — a separate account inside Microsoft Entra ID. A plain agent identity gets tokens marked `idtyp=app`; an agent user gets `idtyp=user`, which is what APIs and services demand when they insist on a real user identity, such as Exchange mailboxes, Teams, and org charts.

Four steps, each with an HTTP call and a PowerShell equivalent built on `Invoke-MgGraphRequest`. First confirm the agent identity came from an agent identity blueprint: the service principal must carry `@odata.type: #microsoft.graph.agentIdentity` and `servicePrincipalType: ServiceIdentity`. Then create the user with `POST https://graph.microsoft.com/beta/users/microsoft.graph.agentUser`, passing `accountEnabled`, `displayName`, `mailNickname`, `userPrincipalName`, and `identityParentId`. Optionally attach a manager through `manager/$ref`, and assign a license after setting `usageLocation`.

Agent users have no password — they authenticate with the credentials of the parent agent identity. The link is strictly 1:1, so a second user for the same identity comes back as `400 Bad Request`. You need a tenant with Agent ID support, one of the permissions such as `AgentIdUser.ReadWrite.IdentityParentedBy`, and the Agent ID Administrator role. Point `identityParentId` at an ordinary application service principal and the call fails, which is exactly why step 1 exists.

## Requirements
- Works with: Azure

## Install

### GitHub Copilot (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add github/awesome-copilot --skill entra-agent-user
```

2. **GitHub CLI**
```bash
gh skill install github/awesome-copilot entra-agent-user
```

3. **Manually: put the files in place**
- File: `.github/skills/entra-agent-user/SKILL.md`

### Claude Code

1. **Skills CLI (Vercel)**
```bash
npx skills add github/awesome-copilot --skill entra-agent-user -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/entra-agent-user/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/entra-agent-user/

### Codex

**Manually: put the files in place**
- File: `.agents/skills/entra-agent-user/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/entra-agent-user/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/github/awesome-copilot --path skills/entra-agent-user
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/entra-agent-user/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/github/awesome-copilot/tree/HEAD/skills/entra-agent-user/SKILL.md

## When to use it
- create an agent user from an agent identity via Microsoft Graph
- give an agent an Exchange mailbox and Teams presence
- verify a service principal is a real agentIdentity, not a plain app
- attach an agent to a manager for the org chart
- set usageLocation and assign a license to an agent

## Example prompts
- Create an agent user for this agent identity and show me the Graph API response
- Check that the service principal has `@odata.type` `#microsoft.graph.agentIdentity` and `servicePrincipalType` `ServiceIdentity`
- Assign a license to the agent: set `usageLocation` first, then call `assignLicense`

# SKILL: Creating Agent Users in Microsoft Entra Agent ID

## Overview

An **agent user** is a specialized user identity in Microsoft Entra ID that enables AI agents to act as digital workers. It allows agents to access APIs and services that strictly require user identities (e.g., Exchange mailboxes, Teams, org charts), while maintaining appropriate security boundaries.

Agent users receive tokens with `idtyp=user`, unlike regular agent identities which receive `idtyp=app`.

---

## Prerequisites

- A **Microsoft Entra tenant** with Agent ID capabilities
- An **agent identity** (service principal of type `ServiceIdentity`) created from an **agent identity blueprint**
- One of the following **permissions**:
  - `AgentIdUser.ReadWrite.IdentityParentedBy` (least privileged)
  - `AgentIdUser.ReadWrite.All`
  - `User.ReadWrite.All`
- The caller must have at minimum the **Agent ID Administrator** role (in delegated scenarios)

> **Important:** The `identityParentId` must reference a true agent identity (created via an agent identity blueprint), NOT a regular application service principal. You can verify by checking that the service principal has `@odata.type: #microsoft.graph.agentIdentity` and `servicePrincipalType: ServiceIdentity`.

---

## Architecture

```
Agent Identity Blueprint (application template)
    │
    ├── Agent Identity (service principal - ServiceIdentity)
    │       │
    │       └── Agent User (user - agentUser) ← 1:1 relationship
    │
    └── Agent Identity Blueprint Principal (service principal in tenant)
```

| Component | Type | Token Claim | Purpose |
|---|---|---|---|
| Agent Identity | Service Principal | `idtyp=app` | Backend/API operations |
| Agent User | User (`agentUser`) | `idtyp=user` | Act as a digital worker in M365 |

---

## Step 1: Verify the Agent Identity Exists

Before creating an agent user, confirm the agent identity is a proper `agentIdentity` type:

```http
GET https://graph.microsoft.com/beta/servicePrincipals/{agent-identity-id}
Authorization: Bearer <token>
```

Verify the response contains:
```json
{
  "@odata.type": "#microsoft.graph.agentIdentity",
  "servicePrincipalType": "ServiceIdentity",
  "agentIdentityBlueprintId": "<blueprint-id>"
}
```

### PowerShell

```powershell
````
