+# Agent Targeted Messages
+
+This sample demonstrates how to use **targeted messaging** in Microsoft Teams. Targeted messages are private messages that appear in a shared channel or group chat but are **only visible to a specific user**. The sample implements a reminder agent where all agent responses — confirmations, reminder deliveries, active reminder lists, and snooze confirmations — are sent as targeted messages.

+
+- Agents
+- Targeted Messaging (`MessageActivity.withRecipient()`)
+- Proactive Targeted Messaging (`app.send()`)
+- Adaptive Cards with `Action.Execute`
+- Mention Stripping (`stripMentionsText()`)
+
+## Interaction with Agent
+
+![Targeted Messages Agent](agent-targeted-messages.gif)
+
+### Set a Reminder
+
+- `remind me in 5 minutes to check email`
+- `remind me in 1 hour meeting starts`
+- `remind me in 30 seconds test`
+- `remind @John in 10 minutes review PR`
+
+### Supported Time Formats
+
+- Seconds: `30 seconds`, `30 secs`, `30s`

+- Hours: `1 hour`, `2 hrs`, `1h`
+
+### Manage Reminders
+
+- `my-reminders` — View your active reminders (targeted, only you see the list)
+- `cancel-reminder [id]` — Cancel a specific reminder
+- `reminder-help` — Show help information
+
+### Where Targeted Messages Are Used
+
+Every agent response in this sample is a targeted message — only the intended recipient can see it:
+
+| Action | Recipient | How |
+|---|---|---|
+| Setting a reminder | The command sender | `send(new MessageActivity(...).withRecipient(creator, true))` |
+| Reminder delivery | The reminder target | `app.send(conversationId, new MessageActivity(...).withRecipient(recipient, true))` |
+| Viewing active reminders | The command sender | `send(new MessageActivity(...).withRecipient(sender, true))` |
+| Snooze confirmation | The snoozing user | `send(new MessageActivity(...).withRecipient(recipient, true))` |
+

+
+# How to run these samples
+
+1. You can run these samples locally in the Teams Client after you have provisioned the Teams Application and configured it with your local DevTunnels URL.
+
+## Run in the Teams Client
+
+To run these samples in the Teams Client, you need to provision your app in a M365 Tenant, and configure the app to your DevTunnels URL.
+
+1. Install the tool DevTunnels https://learn.microsoft.com/en-us/azure/developer/dev-tunnels/get-started
+2. Get Access to a M365 Developer Tenant https://learn.microsoft.com/en-us/office/developer-program/microsoft-365-developer-program-get-started
+3. Create a Teams App with the Bot Feature in the Teams Developer Portal (in your tenant) https://dev.teams.microsoft.com
+
+### Configure DevTunnels
+
+Create a persistent tunnel for the port 3978 with anonymous access
+
+```
+devtunnel create -a my-tunnel  
+devtunnel port create -p 3978  my-tunnel 
+devtunnel host  my-tunnel
+```
+
+Take note of the URL shown after *Connect via browser:*
+
+### Provisioning the Teams Application
+
+Navigate to the Teams Developer Portal http://dev.teams.microsoft.com
+
+#### Create a new Bot resource
+
+1. Navigate to `Tools->Bot management`, and add a `New bot`
+1. In Configure, paste the Endpoint address from devtunnels and append `/api/messages`
+1. In Client secrets, create a new secret and save it for later
+
+> Note. If you have access to an Azure Subscription in the same Tenant, you can also create the Azure Bot resource ([learn more](https://learn.microsoft.com/en-us/azure/bot-service/abs-quickstart?view=azure-bot-service-4.0&tabs=singletenant)).
+
+#### Create a new Teams App
+
+1. Navigate to `Apps` and create a `New App`
+1. Fill the required values in Basic information (short and long name, short and long description and App URLs)
+1. In `App features->Bot` select the bot you created previously
+1. Select `Preview in Teams`
+
+> Note. When using an Azure Bot resource, provide the ClientID instead of selecting an existing bot.
+
+## Configure the new project to use the new Teams Bot Application
+
+For NodeJS and Python you will need a `.env` file with the next fields
+
+```
+TENANT_ID=
+CLIENT_ID=
+CLIENT_SECRET=
+```
+
+For dotnet you need to add these values to `appsettings.json` or `launchSettings.json` using the next syntax.
+
+appsettings.json
+
+
+```json
+"urls" : "http://localhost:3978",
+"Teams": {
+    "ClientID": "",
+    "ClientSecret": "",
+    "TenantId": ""
+  },
+```
+
+Or to use Env Vars from the profile defined in `launchSettings.json` (using the Environment Configuration Provider)
+
+```json
+ "teamsbot": {
+      "commandName": "Project",
+      "dotnetRunMessages": true,
+      "launchBrowser": false,
+      "applicationUrl": "http://localhost:3978",
+      "environmentVariables": {
+        "ASPNETCORE_ENVIRONMENT": "Development",
+        "Teams__TenantId": "YOUR_TenantId",
+        "Teams__ClientID": "YOUR_ClientId",
+        "Teams__ClientSecret": "YOUR_ClientSecret"
+      }
+    }
+```
+
+## Pro Tip: Read the configuration settings using the Azure CLI
+
+To obtain the TenantId, ClientId and ClientSecret you can use the Azure CLI with:
+
+> Note. If you don't have access to an Azure Subscription you can still use the Azure CLI, make sure you login with `az login --allow-no-subscription` 
+
+```
+az ad app credential reset --id $appId
+```
+
+## Troubleshooting
+
+- If Teams cannot communicate with your agent, verify your DevTunnels URL is reachable.
+- Ensure your .env or appsettings file is setup correctly.
+- Use the Channels UI in Azure Bot Service in the Azure Portal to see detailed endpoint errors (not available in Teams Developer Portal).

+# Agent Targeted Messages in Microsoft Teams - TypeScript
+
+This sample demonstrates how to use **targeted messaging** in Microsoft Teams with an agent. Targeted messages are private messages that appear in a shared channel or group chat but are **only visible to a specific user**. The sample implements a reminder agent where all agent responses — confirmations, reminder deliveries, active reminder lists, and snooze confirmations — are sent as targeted messages. The agent includes commented-out stubs showing where agentic flows (e.g., LLM-based intent parsing, smart scheduling, and summarization) can be integrated.
+
+## Prerequisites
+
+- [Node.js](https://nodejs.org/) (LTS version recommended)
+
+## Run the sample
+
+1. Navigate to this directory:
+   ```
+   cd agent-targeted-messages/nodejs/agent-targeted-messages
+   ```
+
+2. Install dependencies:
+   ```
+   npm install
+   ```
+
+3. Run the agent:
+   ```
+   npm start
+   ```
+
+The agent will start listening on `http://localhost:3978`.
+
+Refer to the main [README.md](../../README.md) to interact with your agent in the agentsplayground or in Teams.
