Setting Up a Strands Agent with AWS Bedrock

Voiced by Amazon Polly

Overview of Strands Agents

Strands Agents is an open-source SDK from AWS that simplifies the development of AI agents through a model-driven approach. It allows you to define a task-specific prompt and tools the agent can use, and relies on foundation models like Claude, LLaMA, or models available in Amazon Bedrock.

With Strands, developers can create intelligent agents that plan, reason, and reflect while completing tasks using minimal code. It is already used internally by several AWS services such as Amazon Q Developer and AWS Glue.

Handle Common Errors

AccessDeniedException for Model ID

  • Make sure you’re using a region where your AWS account has access to the Bedrock model.
  • Double-check IAM permissions for Bedrock.

Region Configuration

  • Ensure AWS_REGION is exported correctly before importing the strands module.

Conditional Write Error

  • If you encounter an error like “pre-condition failed”, verify if you’re trying to overwrite an existing object in S3 via a conditional call — this doesn’t apply directly to Strands, but could arise if tools use S3.

Clean Up Resources

Once testing is done:

  • Deactivate Bedrock Model access enabled
  • Deactivate and remove your virtual environmentml
