## What it does

This skill covers the Microsoft 365 Agents SDK for TypeScript and Node.js. Its examples use `AgentApplication` to route events and `startServer` to host an agent with Express. They also show invoke handling and messages sent in streaming chunks with `streamingResponse`.

For Azure OpenAI, the skill demonstrates streaming generated text. Copilot Studio examples start a conversation through `CopilotStudioClient` and connect the client to WebChat with `CopilotStudioWebChat`. Azure OpenAI setup uses environment values such as `AZURE_API_KEY` and `AZURE_OPENAI_DEPLOYMENT_NAME`; Copilot Studio uses environment and client identifiers, a schema name, and a bearer token. The author advises checking current API signatures in Microsoft documentation and package versions on npm, so verify those details before relying on the samples.

## Requirements
- Works with: Azure

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add microsoft/skills --skill m365-agents-ts -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/m365-agents-ts/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/m365-agents-ts/

### Codex

**Manually: put the files in place**
- File: `.agents/skills/m365-agents-ts/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/m365-agents-ts/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install microsoft/skills m365-agents-ts
```

2. **Manually: put the files in place**
- File: `.github/skills/m365-agents-ts/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/microsoft/skills --path .github/plugins/azure-sdk-typescript/skills/m365-agents-ts
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/m365-agents-ts/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/microsoft/skills/tree/HEAD/.github/plugins/azure-sdk-typescript/skills/m365-agents-ts/SKILL.md

## When to use it
- route agent messages with `AgentApplication`
- host a Microsoft 365 agent through Express
- send Azure OpenAI output as streaming chunks
- connect an SDK client to Copilot Studio
- handle invoke activities and return a response

## Example prompts
- Create a TypeScript Teams agent with `AgentApplication` routing and start it with `startServer`.
- Add an Azure OpenAI streaming reply for user messages with `streamingResponse`.
- Connect `CopilotStudioClient` and display its replies in WebChat.

# Microsoft 365 Agents SDK (TypeScript)

Build enterprise agents for Microsoft 365, Teams, and Copilot Studio using the Microsoft 365 Agents SDK with Express hosting, AgentApplication routing, streaming responses, and Copilot Studio client integrations.

## Before implementation

- Use the microsoft-docs MCP to verify the latest API signatures for AgentApplication, startServer, and CopilotStudioClient.
- Confirm package versions on npm before wiring up samples or templates.

## Installation

```bash
npm install @microsoft/agents-hosting @microsoft/agents-hosting-express @microsoft/agents-activity
npm install @microsoft/agents-copilotstudio-client
```

## Environment Variables

```bash
PORT=3978
AZURE_RESOURCE_NAME=<azure-openai-resource>
AZURE_API_KEY=<azure-openai-key>
AZURE_OPENAI_DEPLOYMENT_NAME=gpt-4o-mini

TENANT_ID=<tenant-id>
CLIENT_ID=<client-id>
CLIENT_SECRET=<client-secret>

COPILOT_ENVIRONMENT_ID=<environment-id>
COPILOT_SCHEMA_NAME=<schema-name>
COPILOT_CLIENT_ID=<copilot-app-client-id>
COPILOT_BEARER_TOKEN=<copilot-jwt>
```

## Core Workflow: Express-hosted AgentApplication

```typescript
import {
  AgentApplication,
  TurnContext,
  TurnState,
} from "@microsoft/agents-hosting";
import { startServer } from "@microsoft/agents-hosting-express";

const agent = new AgentApplication<TurnState>();

agent.onConversationUpdate("membersAdded", async (context: TurnContext) => {
  await context.sendActivity("Welcome to the agent.");
});

agent.onMessage("hello", async (context: TurnContext) => {
  await context.sendActivity(`Echo: ${context.activity.text}`);
});

startServer(agent);
```

## Streaming responses with Azure OpenAI

```typescript
import { azure } from "@ai-sdk/azure";
import {
  AgentApplication,
  TurnContext,
  TurnState,
} from "@microsoft/agents-hosting";
import { startServer } from "@microsoft/agents-hosting-express";
import { streamText } from "ai";

const agent = new AgentApplication<TurnState>();

agent.onMessage("poem", async (context: TurnContext) => {
  context.streamingResponse.setFeedbackLoop(true);
  context.streamingResponse.setGeneratedByAILabel(true);
  context.streamingResponse.setSensitivityLabel({
    type: "https://schema.org/Message",
    "@type": "CreativeWork",
    name: "Internal",
  });

  await context.streamingResponse.queueInformativeUpdate("starting a poem...");

  const { fullStream } = streamText({
    model: azure(process.env.AZURE_OPENAI_DEPLOYMENT_NAME || "gpt-4o-mini"),
    system: "You are a creative assistant.",
    prompt: "Write a poem about Apollo.",
  });

  try {
    for await (const part of fullStream) {
````
