AI brief

Amazon Bedrock AgentCore now includes a system prompt optimizer that converts production traces into proposed configuration changes and validates them before they are promoted. AWS detailed how the optimizer's reflector engine works and shared benchmark results.

Why it matters: It lets teams tune agent system prompts from real production traces rather than manual trial and error.
