One thing to look at

2 stars2 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Format and validate Terraform code with the fmt / init / validate / tflint loop. Use after editing any .tf file, before committing Terraform changes, when asked to lint, format, validate, or check Terraform modules and root configurations, or when setting up tflint for a repository.

The file declares its own license as MIT. That is the author’s claim about this one file, and it is not the same thing as the license GitHub reports for the repository, which is listed with the other numbers below.

Terraform validation workflow

Run this loop after editing Terraform and before every commit. Fix findings and repeat until all three stages are clean — never commit with failures.

1. Format

From the repository root:

terraform fmt -recursive

This rewrites files in place. In CI or to check without writing, use terraform fmt -recursive -check -diff.

2. Validate

Per changed module or root configuration (validation is per-directory, not monorepo-wide):

terraform -chdir=<module-dir> init -backend=false   # first run only; downloads providers
terraform -chdir=<module-dir> validate

-backend=false skips state/backend configuration — validation needs providers, not state. Validate catches type errors, unknown arguments, and missing required attributes.

3. Lint

tflint --init        # once per clone; downloads rulesets (needs network)
tflint --chdir=<module-dir>

If the repository has no .tflint.hcl, offer to seed one from this skill's bundled tflint.hcl — it enables the recommended Terraform preset plus naming-convention, documented-variables/outputs, unused-declarations, and required-version/providers rules. Add a provider-specific ruleset (AWS/Azure/GCP) only if the repository targets that provider; the bundled config keeps it commented out.

4. Repeat

Re-run the loop after fixing findings. The stages are ordered cheapest-first: fmt is instant, validate needs providers, tflint needs rulesets. A module is done when all three pass.

Notes:

terraform validate spawns provider plugins that communicate over local Unix sockets; in sandboxed environments, ensure Unix-socket connections are permitted or run validation outside the sandbox.
tflint enforces several conventions from the terraform-style skill mechanically (documented variables/outputs, required version/provider constraints, naming) — treat its findings as style violations, not suggestions.
