Key Additions

Memory Store (365 days) · 4 New Pages · ECS/EKS Container Cost · OpenCost Integration · 3 Hardcoded Values Removed

AgentCore Memory Store

Introduced a Memory Store that retains per-user conversation history for 365 days. Storage/search logic is managed in src/lib/agentcore-memory.ts.

Item	Description
Retention Period	365 days (eventExpiryDuration)
User Isolation	Email extracted from Cognito JWT (src/lib/auth-utils.ts)
Stored Data	Question, summary, route, tools used, response time
Setup Script	06e-setup-agentcore-memory.sh
Config File	memoryId, memoryName in data/config.json

Memory Naming Rules

Memory names cannot use hyphens (-). Only underscores (_) are allowed. Correct: awsops_memory / Incorrect: awsops-memory

AgentCore Page Integration:

• 6 StatsCards: total calls, average response time, per-gateway call ratio, per-model token usage
• Conversation history search: keyword, date range, per-route filters

AI Page Integration:

• Bottom toggle panel for viewing conversation history
• Ability to reference previous question/response context

New Pages (4)

Page	Path	Query File	Key Features
EBS	/ebs	queries/ebs.ts	Volumes/snapshots, encryption, EC2 attachments, idle volume detection
MSK	/msk	queries/msk.ts	Kafka clusters, broker node metrics (CPU/Memory/Network), KRaft mode
OpenSearch	/opensearch	queries/opensearch.ts	Domains, N2N/At-Rest encryption, VPC configuration, cluster status
Resource Inventory	/inventory	resource-inventory.ts	Quantity trends for 18 resource types (snapshot-based, zero additional queries)

Steampipe JSONB Notes

• MSK: provisioned column is JSONB containing broker count, storage size, etc.
• OpenSearch: Check the enabled field within the encryption_at_rest_options JSONB
• Always verify column names via information_schema.columns before writing queries

Container Cost Analysis

Added 2 pages and APIs for analyzing ECS and EKS container costs.

Item	ECS (/container-cost)	EKS (/eks-container-cost)
Data Source	CloudWatch Container Insights	OpenCost API
Fallback	None	Request-based calculation
Cost Calculation	Fargate vCPU/GB pricing applied	Pod CPU/Memory allocation cost
API Route	/api/container-cost	/api/eks-container-cost
Setup	-	06f-setup-opencost.sh (Prometheus + OpenCost)

AI Routing Improvements

Item	Before	After
AgentCore Config	Hardcoded in code	ARN read from data/config.json
Tool Usage Display	None	Keyword matching infers MCP tools → UI badges
Multi-Route Failure	Total failure	Bedrock Direct fallback
Timeout	60s	90s

Tool Usage Inference

AgentCore returns only final text (no tool_call tags). The extractUsedTools() function matches keywords in the response content to infer which MCP tools were used and displays them as badges in the UI.

Security Enhancements

Issue	Fix
Sign Out	HttpOnly cookie server-side API deletion (POST /api/auth)
Hardcoded #1	Steampipe password → dynamic lookup
Hardcoded #2	Code Interpreter ID → data/config.json
Hardcoded #3	Gateway URL → data/config.json
