A security review of AWS, Google Cloud, or Microsoft Azure infrastructure. It checks cloud settings for public exposure, excessive permissions, misconfigurations, and compliance gaps.

Use it to review cloud accounts, regions, identity and access settings, storage such as S3 buckets, and infrastructure files from tools like Terraform, CloudFormation, or Pulumi.

It helps reveal unsafe cloud settings and access arrangements before they create security problems or leave resources exposed.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00080	$0.01197
Opus 5	$0.00040	$0.00598
Sonnet 5	$0.00016	$0.00239
Haiku 4.5	$0.00008	$0.00120

Security

Grade A, and why

cloud-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 13d 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.

Cloud Audit — Cloud Infrastructure Security Review

Audit cloud infrastructure configurations for misconfigurations, excessive permissions, public exposure, and compliance gaps. Covers AWS, GCP, and Azure.

Cross-references: iam-audit for the consultant-style IAM deep-dive (design / audit / migrate across identity providers and federation patterns) — this skill includes an IAM section but stays at the cloud-posture level; for role design, JIT access, workload identity federation, and migration plans, invoke iam-audit. container-audit for Kubernetes-specific posture sitting on top of cloud. secrets-audit for secrets-manager hygiene and rotation.

Findings should use the three-disposition rule (Fixed / Deferred / Accepted Risk) per owasp-audit's Report Format.

Scope the Audit

Identify:

Cloud provider(s) and account(s)
Regions in use
Whether CLI tools are available (aws, gcloud, az) or reviewing IaC files (Terraform, CloudFormation, Pulumi)

Audit Categories

Identity and Access Management

AWS:

aws iam get-account-summary
aws iam list-users
aws iam generate-credential-report && aws iam get-credential-report --output text --query Content | base64 -d

Check for: root account usage without MFA, access keys older than 90 days, unused credentials, wildcard permissions ("Action": "*"), overprivileged roles.

GCP:

gcloud projects get-iam-policy $PROJECT_ID
gcloud iam service-accounts list

Check for: primitive roles (Owner/Editor) on too many principals, unused service accounts, service account keys instead of workload identity.

Azure:

az role assignment list --all
az ad user list

Check for: excessive Owner/Contributor assignments, guest users with high privileges.

IaC review: Grep Terraform/CloudFormation files for "Action": "*", "Resource": "*", hardcoded secrets, overly broad trust policies.

Network Security

Check for:

Security groups or firewall rules allowing 0.0.0.0/0 ingress
Unrestricted SSH (port 22) or RDP (port 3389) from the internet
VPC flow logs disabled
Databases in public subnets
Missing network segmentation between tiers

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.
