feat(02-use-cases): integrate AgentCore Memory with SRE Agent for intelligent context-aware incident response (#210)
* feat: integrate long-term memory system into SRE agent

- Add AgentCore Memory integration with three memory strategies:
  * User preferences (escalation, notification, workflow preferences)
  * Infrastructure knowledge (dependencies, patterns, baselines)
  * Investigation summaries (timeline, actions, findings)

- Implement memory tools for save/retrieve operations
- Add automatic memory capture through hooks and pattern recognition
- Extend agent state to support memory context
- Integrate memory-aware planning in supervisor agent
- Add comprehensive test coverage for memory functionality
- Create detailed documentation with usage examples

This transforms the SRE agent from stateless to learning assistant
that becomes more valuable over time by remembering user preferences,
infrastructure patterns, and investigation outcomes.

Multi-Agent System

Built on LangGraph, the multi-agent system orchestrates specialized agents for complex investigations.

Supervisor Agent

The central coordinator that:

  • Analyzes incoming queries and determines investigation strategy
  • Routes tasks to appropriate specialist agents based on expertise
  • Coordinates multi-step investigations across multiple domains
  • Manages all memory interactions - only the supervisor has direct access to AgentCore Memory
  • Personalizes investigations based on retrieved user preferences and past investigations

Specialist Agents

Each agent focuses on a specific domain with dedicated tools:

Kubernetes Infrastructure Agent

Handles container orchestration and cluster operations. This agent investigates issues across pods, deployments, services, and nodes by examining cluster state, analyzing pod health, resource utilization, and recent events.

Capabilities:

  • Check pod status across namespaces
  • Examine deployment configurations and rollout history
  • Investigate cluster events for anomalies
  • Analyze resource usage patterns
  • Monitor node health and capacity

Application Logs Agent

Processes log data to find relevant information. This agent understands log patterns, identifies anomalies, and correlates events across multiple services.

Capabilities:

  • Full-text search with regex support
  • Error log aggregation and categorization
  • Pattern detection for recurring issues
  • Time-based correlation of events
  • Statistical analysis of log volumes

Performance Metrics Agent

Monitors system metrics and identifies performance issues. This agent understands relationships between different metrics and provides both real-time analysis and historical trending.

Capabilities:

  • Application performance metrics (response times, throughput)
  • Error rate analysis with thresholding
  • Resource utilization metrics (CPU, memory, disk)
  • Availability and uptime monitoring
  • Trend analysis for capacity planning

Operational Runbooks Agent

Provides access to documented procedures, troubleshooting guides, and best practices. This agent helps standardize incident response by retrieving relevant procedures based on the current situation.

Capabilities:

  • Incident-specific playbooks for common scenarios
  • Detailed troubleshooting guides with step-by-step instructions
  • Escalation procedures with contact information
  • Common resolution patterns for known issues
  • Best practices for system operations

Search Agent

Provides cross-domain information retrieval capabilities:

Capabilities:

  • Unified search across all infrastructure domains
  • Context-aware result ranking and filtering
  • Cross-reference information between different agent domains

Agent Collaboration

The supervisor coordinates complex investigations by:

  1. Breaking down queries into specialized tasks
  2. Routing tasks to appropriate agents in parallel or sequence
  3. Aggregating results from multiple agents
  4. Applying memory-based personalization to findings
  5. Generating unified, context-aware reports

Amazon Bedrock AgentCore

The system leverages three fundamental AgentCore primitives that provide enterprise-grade AI infrastructure:

1. AgentCore Runtime

A serverless execution environment designed specifically for AI agents:

  • Managed Infrastructure: Fully managed compute with automatic scaling from zero to thousands of concurrent sessions
  • Container-based Deployment: Supports ARM64 Docker containers with built-in security and isolation

  • Multi-model Support: Compatible with Amazon Bedrock models and external LLM providers
  • Production Features: Built-in monitoring, logging, debugging, and observability

2. AgentCore Gateway

A secure API bridge that enables agents to interact with backend systems:

  • Protocol Translation: Converts REST/GraphQL/gRPC APIs into standardized MCP (Model Context Protocol) tools
  • Universal Tool Interface: Provides a consistent interface for any agent framework to discover and use tools
  • Enterprise Security: JWT-based authentication with support for multiple identity providers (Cognito, Auth0, Okta)
  • API Management: Health monitoring, automatic retries, rate limiting, and error handling
  • Schema-driven: Uses OpenAPI specifications to automatically generate tool definitions

3. AgentCore Memory

A persistent knowledge system that enables agents to learn and personalize over time:

  • Event-based Storage: Immutable event log that accumulates knowledge without data loss
  • Namespace Isolation: Automatic routing based on actor IDs for user and context separation
  • Flexible Retention: Configurable retention policies for different memory types (30-90 days)
  • Pattern Extraction: Automatic extraction of structured data from unstructured agent responses
  • Cross-session Learning: Enables agents to build on past investigations and user interactions

Integration Architecture

Data Flow

  1. User Query → Supervisor Agent analyzes and retrieves relevant memories
  2. Investigation Planning → Supervisor routes to specialist agents
  3. Tool Execution → Agents access backend APIs through Gateway
  4. Response Processing → Memory system extracts and stores patterns
  5. Report Generation → Personalized report based on user preferences

Security Model

  • IAM Integration: Full AWS IAM support with BedrockAgentCoreFullAccess policy
