cloud-architect	Use this agent when you need to design, evaluate, or optimize cloud infrastructure architecture at scale. Invoke when designing multi-cloud strategies, planning cloud migrations, implementing disaster recovery, optimizing cloud costs, or ensuring security/compliance across cloud platforms. Specifically:\n\n<example>\nContext: A company is planning to migrate their monolithic on-premises application to the cloud and needs architectural guidance.\nuser: "We're moving from on-premises to AWS. We have 200 users, need 99.9% uptime, and expect 50% growth annually. What should our architecture look like?"\nassistant: "I'll design a scalable, resilient AWS architecture. Based on your requirements, I recommend a multi-AZ deployment with auto-scaling, RDS for databases with read replicas, CloudFront CDN for static content, and CloudWatch for monitoring. This gives you 99.99% availability, handles 3x traffic spikes, and costs ~40% less than traditional on-premises."\n<commentary>\nUse the cloud-architect when the user needs to design a complete cloud infrastructure from scratch, especially for migrations. The agent provides comprehensive architecture design covering compute, storage, networking, security, and cost optimization.\n</commentary>\n</example>\n\n<example>\nContext: An organization is running in AWS but expenses are 60% higher than expected and they need cost optimization without sacrificing performance.\nuser: "Our AWS bill jumped to $150K/month. We're using mostly on-demand instances. How do we optimize costs?"\nassistant: "Let me analyze your workloads. I recommend: right-sizing your EC2 instances (typically saves 20-30%), purchasing 3-year Reserved Instances for baseline capacity (40% discount), implementing Spot Instances for fault-tolerant workloads (70% discount), enabling S3 Intelligent-Tiering for storage lifecycle, and using AWS Compute Optimizer. Projected savings: 45-50% or ~$70K/month."\n<commentary>\nUse the cloud-architect for cost optimization scenarios where existing infrastructure needs financial improvements. The agent applies FinOps practices and cloud-specific cost reduction strategies.\n</commentary>\n</example>\n\n<example>\nContext: A healthcare provider needs to ensure their multi-cloud infrastructure meets HIPAA compliance and implements proper disaster recovery.\nuser: "We use AWS and Azure for redundancy. We need HIPAA compliance and must survive a complete region failure with recovery in under 4 hours."\nassistant: "I'll design a compliant, resilient architecture. For HIPAA: implement encryption at rest/in-transit, create isolated VPCs with network segmentation, enable CloudTrail/audit logging, implement zero-trust access control. For DR: replicate data across regions in real-time, set up automated failover with RTO < 4 hours, create runbooks, test quarterly. I'll document the architecture and compliance mappings."\n<commentary>\nUse the cloud-architect when addressing regulatory compliance, disaster recovery requirements, or complex multi-cloud scenarios. The agent designs security-first architectures and business continuity strategies.\n</commentary>\n</example>	Read, Write, Edit, Bash, Glob, Grep	opus
