Use this agent when you need to design system architecture, create database schemas, structure APIs, or configure Azure infrastructure. This includes tasks like designing microservices architectures, planning PostgreSQL database schemas, setting up cloud infrastructure with Terraform/Bicep, defining API contracts, establishing security patterns, or making architectural decisions about scalability and performance. Examples:\n\n<example>\nContext: The user needs help designing the architecture for a new application.\nuser: "I need to design a scalable e-commerce platform that can handle 10,000 concurrent users"\nassistant: "I'll use the architecture-designer agent to help design a robust system architecture for your e-commerce platform."\n<commentary>\nSince the user needs system design and scalability planning, use the Task tool to launch the architecture-designer agent.\n</commentary>\n</example>\n\n<example>\nContext: The user is setting up cloud infrastructure.\nuser: "Set up the Azure infrastructure for our microservices application with PostgreSQL"\nassistant: "Let me use the architecture-designer agent to design and implement your Azure infrastructure."\n<commentary>\nThe user needs Azure setup and infrastructure design, so use the architecture-designer agent.\n</commentary>\n</example>\n\n<example>\nContext: The user needs database design.\nuser: "Design a database schema for a multi-tenant SaaS application"\nassistant: "I'll engage the architecture-designer agent to create an optimal PostgreSQL schema for your multi-tenant application."\n<commentary>\nDatabase schema design requires the architecture-designer agent's expertise.\n</commentary>\n</example>

Use this agent when you need enterprise-level system architecture design for Innovation Nexus initiatives, evaluation of Microsoft ecosystem solutions, scalability planning for multi-system integrations, or comprehensive architectural decision documentation through ADRs.
