Cognito JWT auth locks the gateway, an interceptor Lambda injects identity on a channel the model can't touch, and DynamoDB grows a composite key.Building an Agent on Bedrock AgentCore, Part 4: The Notes Were Always Ephemeralhttps://kenkitts.com/posts/bedrock-agentcore-part-4/Tue, 30 Jun 2026 00:00:00 +0000https://kenkitts.com/posts/bedrock-agentcore-part-4/For three posts the agent has saved your notes to a Python list that dies with the process. This post gives them a real home — DynamoDB behind a Lambda, served to the agent as MCP tools through an AgentCore Gateway. The agent can't tell the remote tools from the local ones. That's the trick, and the knife.Building an Agent on Bedrock AgentCore, Part 3: Giving It a Memory That Outlives the Processhttps://kenkitts.com/posts/bedrock-agentcore-part-3/Sat, 27 Jun 2026 00:00:00 +0000https://kenkitts.com/posts/bedrock-agentcore-part-3/The agent runs in the cloud now, and it still forgets everything the instant the box recycles. This post wires it to AgentCore Memory — durable conversation that survives a cold start, then long-term memory so it remembers you across sessions. Two honest scars included, free of charge.Building an Agent on Bedrock AgentCore, Part 1: The Loop Was Never the Hard Parthttps://kenkitts.com/posts/bedrock-agentcore-part-1/Thu, 25 Jun 2026 00:00:00 +0000https://kenkitts.com/posts/bedrock-agentcore-part-1/I already built an agent from scratch — a while loop and 600 lines of Python. It worked great, right up until I had to run it somewhere other than my laptop. This series is about that 'somewhere.' Part 1: what AgentCore actually is, and a Strands notes agent running locally in 40 lines.Building an Agent on Bedrock AgentCore, Part 2: Teaching It to Run Somewhere I Can Close My Laptophttps://kenkitts.com/posts/bedrock-agentcore-part-2/Thu, 25 Jun 2026 00:00:00 +0000https://kenkitts.com/posts/bedrock-agentcore-part-2/In Part 1 the agent ran on my laptop, which is a great place for software to live right up until you close the lid. This post hands the exact same agent to AgentCore Runtime — one new file, no changes to the agent — and gets it running in the cloud behind a real endpoint.
