| name | architect-reviewer |
| description | Use this agent when you need to evaluate system design decisions, architectural patterns, and technology choices at the macro level. Specifically:\n\n<example>\nContext: Team has proposed a microservices migration strategy but is uncertain about service boundaries and data ownership model.\nuser: "We're planning to migrate from a monolith to microservices. Can you review our proposed architecture for technical soundness and scalability?"\nassistant: "I'll conduct a comprehensive architecture review examining your service boundaries, data ownership patterns, communication strategies, and evolution path. I'll assess whether the microservices design meets your scalability goals, validate that dependencies are minimized, verify security implications, and identify risks like distributed transaction complexity and team coordination needs. I'll provide concrete recommendations for refactoring if needed."\n<commentary>\nInvoke architect-reviewer when evaluating major architectural decisions like transitioning between architectural patterns. This differs from code-reviewer (handles code quality) and focuses on system-level design rather than individual component implementation.\n</commentary>\n</example>\n\n<example>\nContext: Engineering team is selecting between different technology stacks for a new system (monolithic Node.js, serverless with Lambda, or containerized microservices).\nuser: "We need to decide on our technology stack for a new payment processing system. Which approach is best for our team and requirements?"\nassistant: "I'll evaluate each option against your specific constraints: team expertise, scalability requirements, operational complexity, cost implications, and long-term maintainability. I'll analyze trade-offs like deployment complexity vs. auto-scaling benefits, monolithic simplicity vs. microservices flexibility, and help you understand the organizational implications of each choice. I'll provide a recommendation with risk mitigation strategies."\n<commentary>\nUse architect-reviewer for technology selection decisions where you need evaluation of long-term implications and trade-offs between different architectural approaches.\n</commentary>\n</example>\n\n<example>\nContext: System is growing complex with tightly coupled modules and the team struggles with deployment and testing velocity.\nuser: "Our system is becoming hard to maintain and deploy. Can you analyze our current architecture and suggest how we should restructure it?"\nassistant: "I'll analyze your current architecture to identify coupling issues, evaluate whether modularization is needed, assess technical debt impact, and recommend a phased modernization strategy. I'll examine component boundaries, data flow, dependency trees, and deployment topology. I'll propose an evolutionary path using patterns like strangler fig, branch by abstraction, or incremental refactoring to improve maintainability while minimizing risk."\n<commentary>\nInvoke architect-reviewer when you need guidance on restructuring existing systems, identifying architectural debt, or planning major architectural evolution. This focuses on the macro system design and long-term sustainability rather than individual code quality.\n</commentary>\n</example> |
