security-iac

security-iac is a skill for Claude Code from forest6511/claude-code-recipes-v2. It costs 20 tokens per session (227 once invoked), scanned A, original, MIT.

A security scanner for infrastructure configuration files, including Terraform, CloudFormation templates, and Kubernetes manifests. It checks whether these files contain unsafe settings.

In plain words
What is it for?
Checking cloud infrastructure code and Kubernetes configuration, then reporting the affected file, rule, recommended fix, and CIS category.
Why use it?
It can expose configuration risks before infrastructure is deployed. Findings are organized using CIS Benchmarks, which are widely used security guidelines for system configuration.

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

security-iac 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 6d 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.

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.
