gcp-review is a skill for Claude Code from UnitOneAI/SecuritySkills. It costs 83 tokens per session (2,600 once invoked), scanned A, original, MIT.

A security review of Google Cloud Platform settings against the CIS GCP Foundation Benchmark, a published checklist for safer cloud configurations.

In plain words
What is it for?
Use it with Terraform, Deployment Manager, gcloud output, or configuration files. It checks identity and access, organization policies, networks, virtual machines, storage, Cloud SQL, BigQuery, and audit logs.
Why use it?
It helps identify weak access controls, firewall rules, logging, storage, and other cloud settings before they expose systems or data.

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

gcp-review 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 10d 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.

GCP Security Posture Review

Overview

This skill performs a structured security assessment of Google Cloud Platform environments against the CIS Google Cloud Platform Foundation Benchmark v2.0.0. The benchmark is organized into seven sections covering identity and access management, logging and monitoring, networking, virtual machines, storage, Cloud SQL, and BigQuery. Each recommendation is evaluated by inspecting infrastructure-as-code definitions (Terraform, Deployment Manager), gcloud CLI output, or configuration files available in the repository.

The CIS GCP Foundation Benchmark v2.0.0 provides prescriptive guidance for hardening GCP projects and organizations. This skill evaluates each applicable control and produces a findings report with CIS recommendation IDs, severity ratings, and actionable remediation steps.


When to Use

If a target is provided via arguments, focus the review on: $ARGUMENTS

  • Reviewing GCP infrastructure-as-code before deployment
  • Assessing an existing GCP environment's security posture against CIS benchmarks
  • Preparing for a CIS benchmark audit or compliance assessment
  • Evaluating IAM bindings, org policies, VPC firewall rules, Cloud Audit Logs, or GCS bucket configurations
  • Onboarding a new GCP project or organization into a security program

Context

The CIS Google Cloud Platform Foundation Benchmark v2.0.0 is a consensus-driven security configuration guide developed by the Center for Internet Security. It provides prescriptive guidance for configuring GCP projects and organizations to a hardened baseline. Google Cloud's Security Command Center can assess many of these controls natively, making this benchmark the standard for GCP security posture evaluation.

Prerequisites

  • Access to GCP infrastructure-as-code files (Terraform .tf, Deployment Manager .yaml/.jinja)
  • gcloud CLI output or configuration exports (if reviewing a live environment)
  • IAM policy bindings and org policy definitions
  • VPC and firewall rule definitions
  • Cloud Audit Logs configuration

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.
