…estration pattern Step Functions state machine orchestrates multiple Bedrock AgentCore agents in parallel using Map state, then aggregates responses via Bedrock Converse API. Uses NodejsFunction with bundled SDK since @aws-sdk/client-bedrock-agentcore is not in Lambda runtime. Key features: - Parallel multi-agent invocation via SFN Map state - Lambda intermediary handles AgentCore streaming responses - Bedrock Converse aggregation of multi-agent outputs - Configurable agent runtime ARNs and model ID - Retry logic for AgentCore cold starts
- Scope bedrock:InvokeModel to inference profile ARN + foundation-model/* - Scope bedrock:ApplyGuardrail to account guardrails instead of wildcard - Add comment explaining agentcore wildcard (dynamic user-provided ARNs)

Step Functions + Bedrock AgentCore Multi-Agent Orchestration
Orchestrates multiple Bedrock AgentCore agents in parallel using SFN Map state, then aggregates responses via Bedrock Converse API.
Architecture: Trigger Lambda → SFN → Map (parallel AgentCore invocations) → Aggregate Lambda (Bedrock Converse) → Summary
Key decisions:
@aws-sdk/client-bedrock-agentcorevia NodejsFunction (not in Lambda runtime)Deployed and tested — SFN orchestrated 2 AgentCore agents in parallel, produced aggregated summary via Bedrock Converse.
