FAQ
What does this tool tell you?
Risk-gate your infrastructure changes: know the score before you apply.
What affects the result most?
Risk score: resources_destroyed × 3 + resources_modified × 1 + resources_added × 0.5. High-risk operations: destroying databases, modifying security groups, replacing instances. Replacement vs in-place update: 'must be replaced' in plan means downtime if no redundancy.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
