What problem does it solve?
This Skill helps you empirically validate how CloudFormation handles specific resource property changes, ensuring your infrastructure updates behave as expected and preventing costly errors or unexpected downtime.
Core Features & Use Cases
- Empirical Validation: Test if CloudFormation resource property changes trigger replacement or in-place updates.
- Documentation Verification: Verify accuracy of "Update requires" documentation for CloudFormation resources.
- Workaround Justification: Determine if workarounds (e.g., hash-based logical IDs) are necessary before architectural decisions.
- Use Case: Before changing an immutable property on an AWS resource via CloudFormation, use this skill to deploy a minimal test stack, make the change, and observe the actual CloudFormation events to confirm if a replacement occurs.
Quick Start
Use the cfn-behavior-validator skill to test if changing the 'Email' property of an 'AWS::SNS::Subscription' resource causes a replacement.
