Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00097 | $0.03095 |
| Opus 5 | $0.00048 | $0.01548 |
| Sonnet 5 | $0.00019 | $0.00619 |
| Haiku 4.5 | $0.00010 | $0.00310 |
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 5d 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 Review
Overview
This skill performs a structured security review of Infrastructure as Code (IaC) templates covering Terraform, CloudFormation, Pulumi, and Bicep. It identifies security anti-patterns, misconfigurations, and policy violations by applying checks equivalent to those performed by static analysis tools (Checkov, tfsec, KICS, cfn-nag) while grounding findings in established frameworks: the OWASP Infrastructure as Code Security Cheat Sheet, SLSA v1.0 supply chain integrity requirements, and relevant CIS Benchmarks.
The review covers eight security domains: secrets management, public exposure, encryption, IAM and access control, logging, network security, supply chain integrity, and resource hardening. Each finding is mapped to a specific policy rule equivalent from Checkov, tfsec, or KICS.
When to Use
If a target is provided via arguments, focus the review on: $ARGUMENTS
- Reviewing Terraform plans or modules before merge or deployment
- Auditing CloudFormation templates for security misconfigurations
- Evaluating Pulumi or Bicep code for anti-patterns
- Supplementing or replacing static IaC scanning when tooling is unavailable
- Preparing IaC for production deployment with security sign-off
- Investigating findings from Checkov, tfsec, or KICS that need deeper analysis
Context
Infrastructure as Code enables declarative, version-controlled management of cloud resources. This power also means that a single misconfiguration in a template can expose production systems, leak credentials, or create attack surfaces at scale. IaC security scanning is a critical gate in the deployment pipeline.
The OWASP IaC Security Cheat Sheet categorizes common IaC vulnerabilities. SLSA v1.0 provides supply chain integrity requirements relevant to how IaC modules are sourced and deployed. CIS Benchmarks provide the specific configuration baselines against which resource configurations are evaluated.
Prerequisites
What ships with it
1 file 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.
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 UnitOneAI/SecuritySkills (58 stars, last pushed 2mo ago), licensed MIT. It adds 97 tokens to every session and 3,095 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.
