Using reasoning with Anthropic agents

This sample demonstrates how to use extended thinking/reasoning capabilities with Anthropic Claude agents.

What this sample demonstrates

  • Creating an AI agent with Anthropic Claude extended thinking
  • Using reasoning capabilities for complex problem solving
  • Extracting thinking and response content from agent output
  • Managing agent lifecycle

Prerequisites

Before you begin, ensure you have the following prerequisites:

  • .NET 8.0 SDK or later
  • Anthropic API key configured
  • Access to Anthropic Claude models with extended thinking support

Note: This sample uses Anthropic Claude models with extended thinking. For more information, see Anthropic documentation.

Set the following environment variables:

$env:ANTHROPIC_API_KEY="your-anthropic-api-key"  # Replace with your Anthropic API key
$env:ANTHROPIC_MODEL="your-anthropic-model"  # Replace with your Anthropic model

Run the sample

Navigate to the AgentWithAnthropic sample directory and run:

cd dotnet\samples\GettingStarted\AgentWithAnthropic
dotnet run --project .\Agent_Anthropic_Step02_Reasoning

Expected behavior

The sample will:

  1. Create an agent with Anthropic Claude extended thinking enabled
  2. Run the agent with a complex reasoning prompt
  3. Display the agent's thinking process
  4. Display the agent's final response
