01Agent Notes

terraform operations: init, plan, apply, destroy, output, state. Use `terraform plan -json` and `terraform apply -json` for machine output. Always run `terraform init` first. Use `-input=false` for non-interactive mode. `-auto-approve` skips confirmation on apply/destroy. State inspection: `terraform state list`, `terraform state show <resource>`.
