Amazon Bedrock Agents code examples for the SDK for Python

Overview

Shows how to use the AWS SDK for Python (Boto3) to work with Amazon Bedrock Agents.

Amazon Bedrock Agents offer you the ability to build and configure autonomous agents in your application.

⚠ Important

  • Running this code might result in charges to your AWS account. For more details, see AWS Pricing and Free Tier.
  • Running the tests might result in charges to your AWS account.
  • We recommend that you grant your code least privilege. At most, grant only the minimum permissions required to perform the task. For more information, see Grant least privilege.
  • This code is not tested in every AWS Region. For more information, see AWS Regional Services.

Code examples

Prerequisites

For prerequisites, see the README in the python folder.

Install the packages required by these examples by running the following in a virtual environment:

python -m pip install -r requirements.txt

Single actions

Code excerpts that show you how to call individual service functions.

Scenarios

Code examples that show you how to accomplish a specific task by calling multiple functions within the same service.

Run the examples

Instructions

Create and invoke an agent

This example shows you how to do the following:

  • Create an execution role for the agent.
  • Create the agent and deploy a DRAFT version.
  • Create a Lambda function that implements the agent's capabilities.
  • Create an action group that connects the agent to the Lambda function.
  • Deploy the fully configured agent.
  • Invoke the agent with user-provided prompts.
  • Delete all created resources.

Start the example by running the following at a command prompt:

python scenario_get_started_with_agents.py

Create and invoke a flow

Shows how to create a simple flow that generates music playlists. The flow includes a prompt node that generates a playlist for a chosen genre and number of songs. The example creates the nodes and permissions for the flow.

Start the example by running the following at a command prompt:

python flows/playlist_flow.py

When prompted, enter the genre of music and the number of songs you want in the playlist. Optionally, the script can delete the resources that it creates. If you want to use the flow later, such as in the Amazon Bedrock console, enter n when the script prompts you to delete resources. Note that you will then need to manually delete the resources.

List flows

Shows how to List Amazon Bedrock flows, versions of a flow, and aliases of a flow.

Start the example by running the following at a command prompt:

python flows/list_flows.py

The example first lists the flows in the current AWS Region. It then prompts for a flow ID, which you can get from the list of flows. Finally, the example lists the flow versions and flow aliases for the flow ID that you entered.

Tests

⚠ Running tests might result in charges to your AWS account.

To find instructions for running these tests, see the README in the python folder.
