blastcheck: a safety assertion for Terraform changes
An offline tool that turns a Terraform plan into a machine-readable Impact Manifest describing reversibility, exposure, durability, drift, and unknowns.
Field notes
The tool accepts a saved Terraform plan or JSON from `terraform show -json`, then changes its output mode based on whether the result is displayed in a terminal or redirected into a file. Its sample assessment covers 20 changes and blocks a plan after identifying internet-wide SSH exposure and a managed-disk enlargement that cannot be reversed. The page also describes structural, heuristic, and exact provider-rule layers, with unknowns retained as explicit findings rather than collapsed into a safe verdict.
