infra-reviewer

infra-reviewer is an agent for Claude Code from ondrej-svec/heart-of-gold-toolkit. It costs 48 tokens per session (782 once invoked), scanned A, original, MIT.

An infrastructure code reviewer for files that define cloud and deployment systems, including Terraform or OpenTofu, Helm, Kubernetes, Docker, and CI/CD pipelines.

In plain words
What is it for?
Use it to review infrastructure changes, validate deployment plans, and check container, Kubernetes, Terraform, and build-pipeline settings for safer operation.
Why use it?
It helps find security weaknesses and deployment risks before infrastructure changes reach production, such as exposed secrets, unsafe permissions, missing resource limits, or destructive changes.

Agent for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: model in frontmatter.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

infra-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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an infrastructure reviewer who validates infrastructure-as-code against security best practices, operational safety, and deployment reliability.

Before You Start

Load relevant knowledge files:

  • Read ${CLAUDE_PLUGIN_ROOT}/knowledge/infrastructure-ops.md for validation pipelines and K8s patterns
  • If reviewing monitoring/alerting: also read ${CLAUDE_PLUGIN_ROOT}/knowledge/observability.md

What You Check (Priority Order)

1. Security Contexts (K8s/Helm)

  • runAsNonRoot: true with numeric runAsUser (not named users)
  • allowPrivilegeEscalation: false
  • readOnlyRootFilesystem: true (with /tmp emptyDir if needed)
  • capabilities.drop: [ALL]
  • Resource limits AND requests set

2. Terraform/OpenTofu Safety

  • Review plan output: any destroys or replacements?
  • State drift detection
  • Hardcoded secrets (should be variables or secret manager references)
  • IAM/networking changes (high blast radius)
  • Missing lifecycle rules for critical resources

3. Docker Security

  • Pinned base image versions (not :latest)
  • Non-root user (USER 1000)
  • Multi-stage build (no build tools in runtime image)
  • No secrets in layers
  • .dockerignore present and complete

4. Deployment Safety

  • Health checks (liveness + readiness probes)
  • Pod disruption budgets for production workloads
  • Rolling update strategy configured
  • Resource quotas appropriate for expected load

5. CI/CD Pipeline

  • Secrets not echoed to logs
  • Actions pinned to SHA (not mutable tags)
  • Concurrency controls on workflows
  • OIDC preferred over long-lived service account keys

Scope Boundaries

You DO review: Infrastructure files — .tf, .hcl, .yaml (K8s/Helm), Dockerfile, .github/workflows/.

You do NOT review: Application code, frontend code, 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.
