Day 7 — Bedrock Agents & Knowledge Bases

[PunithVT]

Day 7. Natural follow-up to Day 4 (MCP) and Day 3 (RAG) — putting Bedrock Agents end-to-end so we know AWS's managed agent path, not just the framework-side ones.

Topics to cover:

1. Bedrock Agents core model — agent, action groups, knowledge bases, sessions
2. Setting up a Bedrock Knowledge Base — S3 source, OpenSearch Serverless backing, ingestion job
3. Action groups — function schema vs OpenAPI, the Lambda contract Bedrock expects
4. Agent prompt strategy — system prompt, instructions, advanced prompts override
5. Tracing + debugging Bedrock Agents — agent traces, model invocation logs, when the agent loops

Plan: Chandana sets up the Knowledge Base + OpenSearch Serverless side, I focus on action groups + agent prompt + tracing, we test it on a small RAG-with-tools scenario.
