Terraform / HCL explainer

AI

Paste root or child module HCL, variables, or a single resource block. You will get a structured overview of providers, resources, and inputs—without running Terraform or OpenTofu.

What to include

Paste the smallest HCL block that answers your question: a resource, module call, variables file, provider block, or output. The explanation can describe intent and common risks, but it cannot read state, contact cloud APIs, or replace a real plan review.

Terraform HCL

?
Paste .tf files or fragments. Nothing runs here—redact tokens, access keys, and backend credentials.

Common use cases

  • Read a teammate’s module before you change variables or add resources.
  • Compare with Kubernetes or Docker manifests when the same stack is deployed multiple ways.
  • Pair with the CI YAML explainer when Terraform runs in a pipeline.
  • Understand providers, resources, variables, outputs, and module calls before reviewing an infrastructure pull request.
  • Summarize what a small HCL snippet intends to create without giving it access to cloud credentials or state.

Common mistakes to avoid

  • Pasting real tokens or backend secrets

    Redact AWS keys, HCP tokens, and .tfvars with secrets. Use placeholders in examples.

  • Treating explanations as a security or compliance sign-off

    Output is educational. Follow your org’s IaC review and policy-as-code process.

  • Forgetting state and provider defaults

    Actual changes depend on state, provider versions, data sources, and defaults that may not appear in the pasted snippet.

  • Pasting complete private infrastructure maps

    Trim to the module or resource you need explained, and replace account ids, domains, and private CIDR details when they are not essential.

FAQ

Does this run terraform plan or apply?

No. Only the text you paste is described. No cloud APIs, no state access, no Terraform binary.

Does it support OpenTofu?

HCL for OpenTofu is the same language. Provider and resource semantics follow HashiCorp-style docs unless you note otherwise.

Can it predict the exact infrastructure diff?

No. Only terraform plan or tofu plan with your state and provider configuration can show the exact diff.

What should I include for module explanations?

Include the module block, relevant variable defaults, and any resource snippets you want explained. Redact secrets and environment-specific identifiers first.
