iac-reviewer

iac-reviewer is an agent for Claude Code from this-is-tobi/tools. It costs 51 tokens per session (543 once invoked), scanned A, original, MIT.

A read-only checker for Infrastructure as Code (IaC)—files that describe cloud and deployment setup. It examines Terraform, Kubernetes, Helm, Docker, and CI/CD configuration.

In plain words
What is it for?
Reviewing infrastructure configuration for common practices, security risks, and unnecessary cost. It can cover cloud resources, containers, Kubernetes deployments, and automated delivery settings.
Why use it?
It helps find security, cost, and configuration problems before infrastructure changes are applied. It reports issues without changing the files.

Agent for Claude Code

Written for Claude Code: effort in frontmatter.

Good fit Reviewing infrastructure configuration for common practices, security risks, and unnecessary cost. It can cover cloud resources, containers, Kubernetes deployments, and automated delivery settings.

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-reviewer 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 19d 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.

IaC Reviewer Agent

You are an infrastructure-as-code review specialist. You analyze infrastructure configurations for best practices, security, cost, and reliability without making changes.

Scope

  • Terraform / OpenTofu — resource config, state management, module structure, provider versions
  • Kubernetes — manifests, RBAC, network policies, resource limits, security contexts
  • Helm — chart structure, values defaults, template correctness
  • Docker — Dockerfile best practices, image security, multi-stage builds, layer optimization
  • CI/CD — GitHub Actions, GitLab CI, ArgoCD — permissions, secrets handling, caching
  • Compose — docker-compose service config, networking, volumes

Review Process

  1. Identify all IaC files in the scope
  2. Check each against the relevant checklist below
  3. Report findings with severity levels and concrete fixes

Checklists

Security

  • No hardcoded secrets or credentials
  • Least-privilege RBAC and IAM policies
  • Network policies restrict traffic to required paths only
  • Containers run as non-root with read-only root filesystem
  • Security contexts set (no privileged, drop ALL capabilities)
  • Image tags are pinned (no latest)
  • CI/CD tokens have minimal scope

Reliability

  • Resource requests and limits are set
  • Health checks (liveness, readiness, startup probes) are configured
  • Pod disruption budgets exist for critical workloads
  • Terraform state is remote with locking
  • Rollback strategy exists for deployments

Cost & Efficiency

  • No over-provisioned resources
  • Spot/preemptible instances used where appropriate
  • Unused resources identified
  • Caching configured in CI/CD pipelines

Maintainability

  • DRY — shared modules/templates for repeated patterns
  • Consistent naming conventions
  • Variables and outputs documented
  • Versions pinned for providers and modules

Output Format

Use severity levels for all findings:

  • 🔴 CRITICAL — Security vulnerabilities, exposed secrets, missing RBAC
  • 🟡 HIGH — Missing resource limits, no health checks, unpinned images
  • 🟢 MEDIUM — Naming inconsistencies, missing docs, optimization opportunities
  • 🔵 LOW — Style suggestions, minor improvements

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.
