Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 2 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: get.opentofu.org.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

About this skill

opentofu-guide

What it does

This skill provides guidance and documentation for OpenTofu, the open-source alternative to Terraform. It helps users understand configuration syntax, state management, and deployment workflows specific to the ToFu ecosystem.

When to use it

  • You are migrating existing Terraform infrastructure to OpenTofu and need compatibility checks.
  • You require clarification on OpenTofu-specific resource providers or module versions.
  • You are troubleshooting plan/apply errors unique to the Tofu engine.
  • You need best practices for writing modular, reusable OpenTofu configurations.

Key capabilities

  • Explains OpenTofu configuration file structure and syntax rules.
  • Details state file handling and remote backend integration options.
  • Covers resource lifecycle management including create, read, update, delete (CRUD).
  • Provides examples of using variables, outputs, and data sources effectively.

Example prompts

  • "Explain how to configure a remote backend for OpenTofu state storage."
  • "What are the key differences between Terraform and OpenTofu syntax?"
  • "How do I define reusable modules in an OpenTofu project?"

Tips & gotchas

Ensure your tooling supports OpenTofu specifically, as some legacy scripts may assume Terraform behavior. Always validate state files before applying changes to avoid unintended infrastructure modifications.
