terraform fmt and terraform validate, then tflint; if any errors are reported, fix them and re-run until all checks pass cleanly before proceedingterraform plan -out=tfplan and extract a summarized plan highlighting creates, updates, deletes, and especially any destructive actions (recreations or deletions); if the plan fails, see error recovery belowterraform apply tfplan after receiving confirmation. Refuse to apply the plan if approval is withheld, or if destructive changes are present and the user has not explicitly accepted themValidation failures (step 5): Fix reported errors → re-run terraform validate → repeat until clean. For tflint warnings, address rule violations before proceeding.
Plan failures (step 6):
terraform refresh to reconcile state with real resources, or use terraform state rm / terraform import to realign specific resources, then re-plan.terraform init if provider plugins are stale, then re-plan.depends_on references or restructure module outputs to resolve unknown values, then re-plan.After any fix, return to step 5 to re-validate before re-running the plan.

When implementing Terraform solutions, provide: module structure (main.tf, variables.tf, outputs.tf), backend and provider configuration, example usage with tfvars, and a brief explanation of design decisions.
