gcp-sec-audit is a command for Claude Code from HermeticOrmus/LibreSecOps-Claude-Code. It costs 0 tokens per session (1,165 once invoked), scanned A, original, MIT.

A command for auditing the security settings of Google Cloud Platform, Google's cloud infrastructure service. It checks areas such as user access, storage, networks, audit logs, and organization rules.

In plain words
What is it for?
Use it to review a live Google Cloud project, Terraform configuration, exported security findings, or a selected area such as access control or networking.
Why use it?
It helps identify cloud configuration gaps that could expose systems or data before deployment or after organizational changes.

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-sec-audit 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.

How it starts

The opening of the file, as written. The whole thing — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/gcp-sec-audit

Structured security audit of GCP configuration covering IAM, GCS, VPC, Cloud Audit Logs, and Organization Policies.

Trigger

Use when you need to:

  • Review GCP project or organization configuration for security gaps
  • Audit Terraform configurations targeting GCP before deployment
  • Validate Organization Policy constraints and IAM bindings
  • Prepare for a CIS GCP Foundations Benchmark assessment
  • Investigate GCP security posture after organizational changes

Input

One of:

  • Live environment: gcloud CLI authenticated with Viewer role at project or organization level
  • Infrastructure-as-code: Terraform files (.tf) using the Google provider
  • Configuration export: Output from gcloud commands, Security Command Center findings, ScoutSuite reports
  • Specific scope: Focus area (e.g., "IAM only", "networking", "Cloud SQL")

Process

Phase 1: Identity & Access Management

  1. Service account hygiene

    • Service accounts with keys (gcloud iam service-accounts keys list --iam-account=SA_EMAIL)
    • Default service accounts in use ([email protected])
    • Service accounts with basic roles (Owner, Editor)
    • User-managed service account key rotation (keys older than 90 days)
    • Service account impersonation chains
  2. IAM bindings

    • Basic roles (Owner/Editor/Viewer) assigned to any principal
    • allUsers or allAuthenticatedUsers in any IAM binding
    • IAM bindings at organization/folder level (high blast radius)
    • Separation of duties (same principal with conflicting roles)
    • Domain-restricted sharing (constraints/iam.allowedPolicyMemberDomains)
  3. Workload Identity

    • External workloads using service account keys vs Workload Identity Federation
    • GKE workloads using node-level SA vs Workload Identity

Phase 2: Storage Security

  1. Cloud Storage (GCS)
    • Uniform bucket-level access enforced (gcloud storage buckets describe gs://BUCKET)
    • Public buckets (allUsers or allAuthenticatedUsers in bucket IAM)
    • Bucket-level CMEK encryption
    • Retention policies on critical buckets
    • Access logging enabled

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.

gcp-sec-audit is a command published in the GitHub repository HermeticOrmus/LibreSecOps-Claude-Code (4 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,165 tokens. 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 2026-08-31.
