What is terraform-validator?

A checking process for Terraform configuration files, which describe cloud infrastructure, using formatting, syntax checks, linting, planning, and security scans.

Use it to inspect .tf and HCL files, check providers, run Terraform validation, use tflint and Checkov where available, and produce a report with findings.

It helps find invalid configuration, style problems, and potential security issues before infrastructure changes are applied.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/akin-ozer/cc-devops-skills

agentmods

npx agentmods add skills/akin-ozer/cc-devops-skills/terraform-validator

Made for: Claude Code.

Or install devops-skills-plugin, the plugin that ships this one along with the rest of its 31 skills.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00029	$0.04820
Opus 5.5	$0.00012	$0.01928
Sonnet 5.5	$0.00006	$0.00964
Haiku 4.5	$0.00003	$0.00482

Security

Grade A, and why

terraform-validator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/extract_tf_info_wrapper.sh, scripts/extract_tf_info.py, scripts/install_checkov.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Terraform Validator

Comprehensive toolkit for validating, linting, and testing Terraform configurations with automated workflows for syntax validation, security scanning, and intelligent documentation lookup.

⚠️ Critical Requirements Checklist

STOP: You MUST complete these steps in order. Do NOT skip any REQUIRED step.

Step	Action	Required
1	Run `bash scripts/extract_tf_info_wrapper.sh <path>`	✅ REQUIRED
2	Context7 lookup for ALL providers (explicit AND implicit); WebSearch fallback if not found	✅ REQUIRED
3	READ `references/security_checklist.md`	✅ REQUIRED
4	READ `references/best_practices.md`	✅ REQUIRED
5	Run `terraform fmt`	✅ REQUIRED
6	Run `tflint` (or note as skipped if unavailable)	Recommended
7	Run `terraform init` (if not initialized)	✅ REQUIRED
8	Run `terraform validate`	✅ REQUIRED
9	Run `bash scripts/run_checkov.sh <path>`	✅ REQUIRED
10	Cross-reference findings with `security_checklist.md` sections	✅ REQUIRED
11	Generate report citing reference files	✅ REQUIRED
12	Run regression tests (`bash tests/test_regression.sh`)	✅ REQUIRED
13	Run lightweight CI checks (`bash -n`, `py_compile`, smoke)	✅ REQUIRED

IMPORTANT: Steps 3-4 (reading reference files) must be completed BEFORE running security scans. The reference files contain remediation patterns that MUST be cited in your report.

Context7 Fallback: If Context7 does not have a provider (common for: random, null, local, time, tls), use WebSearch: "terraform-provider-{name} hashicorp documentation"

What ships with it

11 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
