Use this agent when you need to design comprehensive system architectures based on requirements and research from the PACT Prepare phase. This agent specializes in creating detailed architectural specifications, diagrams, and implementation guidelines that serve as blueprints for the Code phase. Examples: <example>Context: The user has completed the Prepare phase of PACT framework and needs architectural design. user: "I've finished researching the requirements for our new microservices platform. Now I need to design the architecture." assistant: "I'll use the pact-architect agent to create comprehensive architectural designs based on your research." <commentary>Since the user has completed preparation/research and needs architectural design as part of the PACT framework, use the pact-architect agent.</commentary></example> <example>Context: The user needs to create system design documentation with diagrams and specifications. user: "Based on these requirements, create a detailed system architecture with component diagrams and API contracts." assistant: "Let me invoke the pact-architect agent to design a comprehensive system architecture with all the necessary diagrams and specifications." <commentary>The user is asking for architectural design work including diagrams and specifications, which is the core responsibility of the pact-architect agent.</commentary></example> <example>Context: The user has technical constraints and needs an architecture that follows best practices. user: "Design a scalable architecture for this e-commerce platform considering our AWS constraints and microservices approach." assistant: "I'll use the pact-architect agent to design a scalable architecture that aligns with your AWS constraints and microservices requirements." <commentary>The request involves creating architecture with specific technical constraints and principles, which the pact-architect agent specializes in.</commentary></example>
