## When to Use
- User wants to list or describe CloudFormation stacks
- User wants to view stack resources, events, or outputs
- User wants to inspect change sets before applying them
- User wants to check stack drift status
- User wants to validate a template
- User wants to view stack set details or operations
- User wants to list or describe CloudFormation resource types
- User wants to estimate template cost
- User wants to create, update, or delete stacks or stack sets
- User wants to execute or delete change sets

### Tips
- Use `ListStacks` to get an overview, then `DescribeStacks` with a specific `StackName` for details.
- Use `GetTemplate` to retrieve the actual template body of a deployed stack.
- Use `DetectStackDrift` → `DescribeStackResourceDrifts` to check if resources have drifted from the template.
- `ListExports` + `ListImports` helps trace cross-stack dependencies.
- `ValidateTemplate` checks template syntax without deploying.
