You can use skills to extend another bot.
A skill is a bot that can perform a set of tasks for another bot.
A skill's interface is described by a manifest. Developers who don't have access to the skill's source code can use the information in the manifest to design their skill consumer.
A skill can use claims validation to manage which bots or users can access it.
This article demonstrates how to implement a skill that echoes the user's input.
Some types of skill consumers are not able to use some types of skill bots.
The following table describes which combinations are supported.
Multi-tenant skill
Single-tenant skill
User-assigned managed identity skill
Multi-tenant consumer
Supported
Not supported
Not supported
Single-tenant consumer
Not supported
Supported if both apps belong to same tenant
Supported if both apps belong to same tenant
User-assigned managed identity consumer
Not supported
Supported if both apps belong to same tenant
Supported if both apps belong to same tenant
Note
The Bot Framework JavaScript, C#, and Python SDKs will continue to be supported, however, the Java SDK is being retired with final long-term support ending in November 2023.
Only critical security and bug fixes within this repository will be undertaken.
Existing bots built with the Java SDK will continue to function.
Starting with version 4.11, you don't need an app ID and password to test a skill locally in the Bot Framework Emulator. An Azure subscription is still required to deploy your skill to Azure.
About this sample
The skills simple bot-to-bot sample includes projects for two bots:
The echo skill bot, which implements the skill.
The simple root bot, which implements a root bot that consumes the skill.
This article focuses on the skill, which includes support logic in its bot and adapter.
For deployed bots, bot-to-bot authentication requires that each participating bot has valid identity information.
However, you can test multi-tenant skills and skill consumers locally with the Emulator without an app ID and password.
Optionally, add the skill's identity information to its configuration file. If either the skill or skill consumer provides identity information, both must.
The allowed callers array can restrict which skill consumers can access the skill.
Add an "*" element, to accept calls from any skill consumer.
Note
If you're testing your skill locally without bot identity information, neither the skill nor the skill consumer run the code to perform claims validation.
Optionally, add the skill's identity information to the appsettings.json file.
{
"MicrosoftAppType": "",
"MicrosoftAppId": "",
"MicrosoftAppPassword": "",
"MicrosoftAppTenantId": "",
// This is a comma separate list with the App IDs that will have access to the skill.
// This setting is used in AllowedCallersClaimsValidator.
// Examples:
// [ "*" ] allows all callers.
// [ "AppId1", "AppId2" ] only allows access to parent bots with "AppId1" and "AppId2".
"AllowedCallers": [ "*" ]
}
echo-skill-bot/.env
Optionally, add the skill's identity information to the .env file.
Optionally, add the skill's app ID and password to the application.properties file.
MicrosoftAppId=
MicrosoftAppPassword=
server.port=39783
# This is a comma separate list with the App IDs that will have access to the skill.
# This setting is used in AllowedCallersClaimsValidator.
# Examples:
# * allows all callers.
# AppId1,AppId2 only allows access to parent bots with "AppId1" and "AppId2".
AllowedCallers=*
Optionally, add the skill's app ID and password to the config.py file.
The skill consumer can send information to the skill. One way to accept such information is to accept them via the value property on incoming messages. Another way is to handle event and invoke activities.
The skill in this example doesn't accept input parameters.
To continue or complete a conversation
When the skill sends an activity, the skill consumer should forward the activity on to the user.
However, you need to send an endOfConversation activity when the skill finishes; otherwise, the skill consumer will continue to forward user activities to the skill.
Optionally, use the activity's value property to include a return value, and use the activity's code property to indicate why the skill is ending.

To cancel the skill
For multi-turn skills, you would also accept endOfConversation activities from a skill consumer, to allow the consumer to cancel the current conversation.
The logic for this skill doesn't change from turn to turn. If you implement a skill that allocates conversation resources, add resource cleanup code to the end-of-conversation handler.
protected override Task OnEndOfConversationActivityAsync(ITurnContext<IEndOfConversationActivity> turnContext, CancellationToken cancellationToken)
{
// This will be called if the root bot is ending the conversation. Sending additional messages should be
// avoided as the conversation may have been deleted.
// Perform cleanup of resources if needed.
return Task.CompletedTask;
}
echo-skill-bot/bot.js
Use the onUnrecognizedActivityType method to add an end-of-conversation logic. In the handler, check whether the unrecognized activity's type equals endOfConversation.
this.onEndOfConversation(async (context, next) => {
// This will be called if the root bot is ending the conversation. Sending additional messages should be
// avoided as the conversation may have been deleted.
// Perform cleanup of resources if needed.
// By calling next() you ensure that the next BotHandler is run.
await next();
});
echoSkillBot\EchoBot.java
protected CompletableFuture<Void> onEndOfConversationActivity(TurnContext turnContext) {
// This will be called if the root bot is ending the conversation. Sending
// additional messages should be
// avoided as the conversation may have been deleted.

return CompletableFuture.completedFuture(null);
}
echo-skill-bot/bots/echo_bot.py
async def on_end_of_conversation_activity(self, turn_context: TurnContext):
# This will be called if the root bot is ending the conversation. Sending additional messages should be
# avoided as the conversation may have been deleted.
# Perform cleanup of resources if needed.

Claims validator
This sample uses an allowed callers list for claims validation. The list is defined in the skill's configuration file and is read into the validator object when it's created.
You must add a claims validator to the authentication configuration. The claims are evaluated after the authentication header. Your validation code should throw an error or exception to reject the request. There are many reasons you may want to reject an otherwise authenticated request. For example:
The skill is part of a paid-for service. User's not in the database shouldn't have access.
The skill is proprietary. Only certain skill consumers can call the skill.
Important
If you don't provide a claims validator, your bot will generate an error or exception upon receiving an activity from the skill consumer.
The SDK provides an AllowedCallersClaimsValidator class that adds application-level authorization based on a simple list of IDs of the applications that are allowed to call the skill. If the list contains an asterisk (*), then all callers are allowed. The claims validator is configured in Startup.cs.

Skill adapter
When an error occurs, the skill's adapter should clear conversation state for the skill, and it should also send an endOfConversation activity to the skill consumer. Use the code property of the activity to signal that the skill ended due to an error.

Skill manifest
A skill manifest is a JSON file that describes the activities the skill can perform, its input and output parameters, and the skill's endpoints.
The manifest contains the information you need to access the skill from another bot.
The latest schema version is v2.1.
{
"$schema": "https://schemas.botframework.com/schemas/skills/skill-manifest-2.0.0.json",
"$id": "EchoSkillBot",
"name": "Echo Skill bot",
"version": "1.0",
"description": "This is a sample echo skill",
"publisherName": "Microsoft",
"privacyUrl": "https://echoskillbot.contoso.com/privacy.html",
"copyright": "Copyright (c) Microsoft Corporation. All rights reserved.",
"license": "",
"iconUrl": "https://echoskillbot.contoso.com/icon.png",
"tags": [
"sample",
"echo"
],
"endpoints": [

"msAppId": "00000000-0000-0000-0000-000000000000"
}
]
}
The skill manifest schema is a JSON file that describes the schema of the skill manifest. The current schema version is 2.1.0.
Test the skill
At this point, you can test the skill in the Emulator as if it were a normal bot. However, to test it as a skill, you would need to implement a skill consumer.
Run the echo skill bot locally on your machine. If you need instructions, refer to the README file for the C#, JavaScript, Java, or Python sample.
Use the Emulator to test the bot as shown below. When you send an "end" or "stop" message to the skill, it sends an endOfConversation activity in addition to the reply message. The skill sends the endOfConversation activity to indicate the skill has finished.
More about debugging
Since traffic between skills and skill consumers is authenticated, there are extra steps when debugging such bots.
The skill consumer and all the skills it consumes, directly or indirectly, must be running.
If the bots are running locally and if any of the bots has an app ID and password, then all bots must have valid IDs and passwords.
Coming soon: Throughout 2024 we will be phasing out GitHub Issues as the feedback mechanism for content and replacing it with a new feedback system. For more information see: https://aka.ms/ContentUserFeedback.
