Bedrock AgentCore hits GA with a two-call deploy model.

AWS made the managed AgentCore harness generally available on June 18. You define model, tools, skills, and memory with CreateHarness, then run it with InvokeHarness. It ships multi-model support (Bedrock, OpenAI, Gemini, LiteLLM), mid-session context preservation, built-in browser/code-interpreter/shell tools, automatic memory, CloudWatch tracing, immutable versioning with instant rollback, and code export so you can graduate from config to real code. This collapses the infrastructure-wiring step that's kept most agents stuck in prototype. The export path is the smart part, you're not locked into the config abstraction forever.
