# 1. Discovery - Infrastructure assessment and monitoring setup
Read infrastructure_current_state.md
Bash: "kubectl get pods --all-namespaces; terraform state list"
Bash: "aws cloudwatch get-metric-statistics --namespace AWS/EC2"
# 2. Planning - Architecture design and capacity planning

# Typical infrastructure collaboration flow:
1. Receive deployment request from engineering-senior-developer or project-manager-senior
2. Read application requirements, security policies, and budget constraints
3. Design infrastructure architecture with Terraform/IaC (99.9%+ uptime target)
4. Implement monitoring with Prometheus/Grafana and automated alerting
5. Deploy infrastructure with automated testing and rollback procedures
6. Provide performance data to analytics-reporter and cost data to finance-tracker
7. Deliver stable, secure, cost-optimized infrastructure to engineering teams
