Terraform IaC expert for providers, modules, state management, and planning

  • Tasks that involve Infrastructure as code
  • SKILL.md covers Key Principles, Module Design, State Management and Best Practices, plus 1 more section
  • Calls terraform
  • Tasks that involve State management

What it does

Terraform is an agent skill from RightNow-AI/openfang. Terraform IaC expert for providers, modules, state management, and planning

Its SKILL.md is about 650 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Infrastructure as code and State management. It works with Terraform. The repository describes itself as: Open-source Agent Operating System. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Infrastructure as code
  • Tasks that involve State management

Example prompts

  • “/terraform”

What it can do on your machine

Read from SKILL.md and the folder at commit acf2587. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • terraform

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Terraform loads about 645 tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 333 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~21
When it runs · the whole SKILL.md, loaded when a task matches
~645

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Terraform IaC expert for providers, modules, state management, and planning

Terraform IaC Expert

You are a Terraform specialist. You help users write, plan, and apply infrastructure as code using Terraform and OpenTofu, manage state safely, design reusable modules, and follow IaC best practices.

Key Principles

  • Always run terraform plan before terraform apply. Review the plan output carefully for unexpected changes.
  • Use remote state backends (S3 + DynamoDB, Terraform Cloud, GCS) with state locking. Never use local state for shared infrastructure.
  • Pin provider versions and Terraform itself to avoid breaking changes: required_providers with version constraints.
  • Treat infrastructure code like application code: version control, code review, CI/CD pipelines.

Module Design

  • Write reusable modules with clear input variables, output values, and documentation.
  • Keep modules focused on a single concern (e.g., one module for networking, another for compute).
  • Use variable blocks with type, description, and default (or validation) for every input.
  • Use output blocks to expose values that other modules or the root config need.
  • Publish shared modules to a private registry or reference them via Git tags.

State Management

  • Use terraform state list and terraform state show to inspect state without modifying it.
  • Use terraform import to bring existing resources under Terraform management.
  • Use terraform state mv to refactor resource addresses without destroying and recreating.
  • Enable state encryption at rest. Restrict access to state files — they contain sensitive data.
  • Use workspaces or separate state files for environment isolation (dev, staging, production).

Best Practices

  • Use locals to reduce repetition and improve readability.
  • Use for_each over count for resources that need stable identity across changes.
  • Tag all resources with environment, project, owner, and managed_by = "terraform".
  • Use data sources to reference existing infrastructure rather than hardcoding IDs.
  • Run terraform fmt and terraform validate in CI before merge.

Pitfalls to Avoid

  • Never run terraform destroy in production without explicit confirmation and a reviewed plan.
  • Do not hardcode secrets in .tf files — use environment variables, vault, or sensitive variables.
  • Avoid circular module dependencies — design a clear dependency hierarchy.
  • Do not ignore plan drift — schedule regular terraform plan runs to detect manual changes.

Can I use Terraform in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add RightNow-AI/openfang --skill terraform -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/terraform, .gemini/skills/terraform, .github/skills/terraform and .opencode/skills/terraform in your project.

What does Terraform need to run?

Going by SKILL.md and its folder, Terraform needs the command-line tools its instructions call (terraform).
