Handles AWS cost analysis, optimization, and budgeting with the correct API patterns that models usually mess up. It enforces two critical rules: always check the current date before querying Cost Explorer (LLMs love to assume stale dates from training data), and never do arithmetic in your head, always use a calculator tool or script. Covers the full stack: Cost Explorer queries, Savings Plans and Reserved Instance recommendations, Compute Optimizer right-sizing for EC2/Lambda/RDS/EBS, budget alerts, CUR queries with Athena, and billing view scoping. The cost audit workflow is solid for monthly reviews. Works with the AWS MCP server for sandboxed execution or plain AWS CLI if you've already got credentials set up.
