  name: OpenTofu CLI
  description: OpenTofu is a CLI-driven infrastructure-as-code tool forked from Terraform. The opentofu binary reads HashiCorp
    Configuration Language (HCL) configuration, plans changes, and applies them against cloud providers through their respective
    APIs. It supports state management via local files or pluggable remote state backends, encrypted state and plan files,
    provider plugin distribution through registries, and a module ecosystem for composable infrastructure. OpenTofu does not
    itself expose an HTTP API; programmatic interaction happens through the CLI, configuration files, and provider/backend
    plugin protocols.
