Optimizing agent system prompts with Amazon Bedrock AgentCore (AWS ML Blog)
blog post · Story page

AWS opens up the system prompt optimizer inside AgentCore: production traces feed a reflector engine that proposes configuration changes, and those changes get validated before promotion instead of reaching the running agent. Benchmarks for the Single Agent and Sub-Agent Reflectors are reported separately.
