cloud-security-engineer

A structured cloud-security review guide for AWS, Azure, and Google Cloud environments. It covers cloud settings, infrastructure code, containers, and user access.

In plain words
What is it for?
Use it to review cloud security posture, check Terraform or similar infrastructure code, harden Kubernetes environments, and assess identity and access controls.
Why use it?
It replaces informal security checks with repeatable reviews that identify unsafe configurations, excessive permissions, and missing protections.

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

cloud-security-engineer 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 yesterday.

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.

Cloud Security Engineer Role Bundle

A structured cloud security guide for engineers who own the security posture of cloud environments across AWS, Azure, and GCP. This bundle replaces ad-hoc cloud configuration reviews with repeatable engagement patterns that produce hardened environments, least-privilege identity configurations, and infrastructure-as-code security baselines.


When to Use

Invoke this role bundle when any of the following conditions are true:

  • Cloud posture review needed. A cloud environment (AWS account, Azure subscription, GCP project) needs a security assessment — either a new environment before workloads are deployed or an existing environment that has never been formally reviewed.
  • IaC security review. Terraform, CloudFormation, Bicep, or Pulumi templates need security validation before being applied to production infrastructure.
  • Container orchestrator hardening. Kubernetes (EKS, AKS, GKE) or other container orchestration platforms need security configuration review — RBAC, network policies, pod security, and workload identity.
  • Identity governance assessment. IAM policies, roles, service accounts, and cross-account/cross-project trust relationships need review for least privilege, unused access, and privilege escalation paths.
  • Zero trust program. The organization is implementing zero trust architecture and needs to assess current posture, define target architecture, and build the implementation roadmap.

If the ask is about application-layer security (e.g., "review this API for BOLA"), use the appsec-engineer role bundle. If the ask is about overall security program maturity, use the vciso role bundle. This bundle is for cloud infrastructure security.

Skills: All skills referenced in this bundle are available: iam-review, threat-modeling, pipeline-security, aws-review, azure-review, gcp-review, container-security, iac-security, zero-trust-assessment, segmentation, privileged-access.

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.

cloud-security-engineer is a skill published in the GitHub repository UnitOneAI/SecuritySkills (56 stars, last pushed 2mo ago), licensed MIT. It adds 79 tokens to every session and 4,598 once invoked, about $0.0004 per session on Opus 5. 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 2026-08-30.
