terraform-validator

terraform-validator is a skill for Claude Code from akin-ozer/cc-devops-skills. It costs 29 tokens per session (4,820 once invoked), scanned A, original, Apache-2.0.

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

In plain words
What is it for?
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.
Why use it?
It helps find invalid configuration, style problems, and potential security issues before infrastructure changes are applied.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is 2. MUST: bash scripts/extract_tf_info_wrapper.sh ./modules/vpc/.

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.

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 8d 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 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.
