# Semantic Kernel: Agent syntax examples
This project contains a collection of examples on how to use _Semantic Kernel Agents_.
#### NuGet:
- [Microsoft.SemanticKernel.Agents.Abstractions](https://www.nuget.org/packages/Microsoft.SemanticKernel.Agents.Abstractions)
- [Microsoft.SemanticKernel.Agents.Core](https://www.nuget.org/packages/Microsoft.SemanticKernel.Agents.Core)
- [Microsoft.SemanticKernel.Agents.OpenAI](https://www.nuget.org/packages/Microsoft.SemanticKernel.Agents.OpenAI)
#### Source
- [Semantic Kernel Agent Framework](https://github.com/microsoft/semantic-kernel/tree/main/dotnet/src/Agents)
The examples can be run as integration tests but their code can also be copied to stand-alone programs.
## Examples
The concept agents examples are grouped by prefix:
Prefix|Description
---|---
OpenAIAssistant|How to use agents based on the [Open AI Assistant API](https://platform.openai.com/docs/assistants).
MixedChat|How to combine different agent types.
ComplexChat|How to deveop complex agent chat solutions.
Legacy|How to use the legacy _Experimental Agent API_.
## Legacy Agents
Support for the OpenAI Assistant API was originally published in `Microsoft.SemanticKernel.Experimental.Agents` package:
[Microsoft.SemanticKernel.Experimental.Agents](https://github.com/microsoft/semantic-kernel/tree/main/dotnet/src/Experimental/Agents)
This package has been superseded by _Semantic Kernel Agents_, which includes support for Open AI Assistant agents.
## Running Examples
Examples may be explored and ran within _Visual Studio_ using _Test Explorer_.
You can also run specific examples via the command-line by using test filters (`dotnet test --filter`). Type `dotnet test --help` at the command line for more details.
Example:
```
dotnet test --filter OpenAIAssistant_CodeInterpreter
```
## Configuring Secrets
Each example requires secrets / credentials to access OpenAI or Azure OpenAI.
We suggest using .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) to avoid the risk of leaking secrets into the repository, branches and pull requests. You can also use environment variables if you prefer.
To set your secrets with .NET Secret Manager:
1. Navigate the console to the project folder:
```
cd dotnet/samples/GettingStartedWithAgents
```
2. Examine existing secret definitions:
```
dotnet user-secrets list
```
3. If needed, perform first time initialization:
```
dotnet user-secrets init
```
4. Define secrets for either Open AI:
```
dotnet user-secrets set "OpenAI:ChatModelId" "..."
dotnet user-secrets set "OpenAI:ApiKey" "..."
```
5. Or Azure Open AI:
```
dotnet user-secrets set "AzureOpenAI:DeploymentName" "..."
dotnet user-secrets set "AzureOpenAI:ChatDeploymentName" "..."
dotnet user-secrets set "AzureOpenAI:Endpoint" "https://... .openai.azure.com/"
dotnet user-secrets set "AzureOpenAI:ApiKey" "..."
```
> NOTE: Azure secrets will take precedence, if both Open AI and Azure Open AI secrets are defined, unless `ForceOpenAI` is set:
```
protected override bool ForceOpenAI => true;
```
