iac-security

iac-security is a skill for Claude Code from snyk/studio-recipes. It costs 90 tokens per session (2,347 once invoked), scanned A, original, Apache-2.0.

A security scanner for infrastructure-as-code, files that describe cloud and cluster resources in formats such as Terraform, Kubernetes, CloudFormation, and Azure ARM.

In plain words
What is it for?
Use it to discover supported infrastructure files, scan them, assess findings by severity, and review safer configuration alternatives.
Why use it?
It finds configuration mistakes, security risks, and compliance problems in code before they reach a deployed environment.

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

iac-security 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.

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.

Infrastructure as Code Security

Comprehensive security scanning for Infrastructure as Code to catch misconfigurations before they become production vulnerabilities.

Core Principle: Security issues are cheaper to fix in code than in production.


Quick Start

1. Identify IaC files (Terraform, K8s, CloudFormation, ARM)
2. Run snyk_iac_scan on the directory
3. Analyze misconfigurations by severity
4. Provide secure configuration alternatives

Supported IaC Formats

Platform File Types
Terraform .tf, .tf.json, .tfvars
Terraform Plan JSON plan output (terraform show -json)
Kubernetes .yaml / .yml with apiVersion + kind
Helm Chart templates (requires Chart.yaml)
AWS CloudFormation .json / .yaml with AWSTemplateFormatVersion
Azure ARM .json with $schema ARM URL
Serverless Framework serverless.yml

Phase 1: Discovery

Goal: Identify all IaC files that need scanning.

Check for these indicators to confirm IaC type:

  • Terraform: .tf files, terraform.tfstate, provider blocks
  • Kubernetes: YAML with apiVersion/kind, directories named k8s, manifests
  • CloudFormation: AWSTemplateFormatVersion key, Resources section with AWS types
  • Azure ARM: $schema containing deploymentTemplate

Then determine scan scope: single file, directory, or recursive.


Phase 2: Execute Scan

Goal: Run appropriate IaC security scan.

Basic Scan

Run snyk_iac_scan with:
- path: <directory or file path>

Terraform with Variables

Run snyk_iac_scan with:
- path: <terraform directory>
- var_file: <path to .tfvars if using variables>

Terraform Plan (more accurate)

terraform plan -out=tfplan
terraform show -json tfplan > tfplan.json
Run snyk_iac_scan with:
- path: tfplan.json
- scan: "planned-values"  # or "resource-changes"

What ships with it

2 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.

iac-security is a skill published in the GitHub repository snyk/studio-recipes (62 stars, last pushed 4d ago), licensed Apache-2.0. It adds 90 tokens to every session and 2,347 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
