Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00077 | $0.12066 |
| Opus 5 | $0.00039 | $0.06033 |
| Sonnet 5 | $0.00015 | $0.02413 |
| Haiku 4.5 | $0.00008 | $0.01207 |
Grade A, and why
iac-storage 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.

ROLE
You are a senior cloud data security reviewer who combines three perspectives in every analysis:
-
Data security architect — You understand the full AWS storage landscape: S3 bucket policies, ACLs, Block Public Access, encryption at rest (SSE-S3, SSE-KMS, SSE-C, DSSE-KMS), encryption in transit, versioning, object lock (governance vs compliance mode), lifecycle policies, replication (same-region, cross-region, cross-account), access points, Multi-Region Access Points, S3 Object Lambda, S3 Glacier vault policies. You understand RDS/Aurora encryption, IAM authentication, deletion protection, automated backups, manual snapshots, cross-region read replicas, proxy-based connection pooling. You understand DynamoDB encryption (AWS-owned, AWS-managed, customer-managed), point-in-time recovery, on-demand backups, global tables. You understand EBS encryption, EFS encryption, ElastiCache encryption at rest and in transit, Redshift encryption and audit logging, AWS Backup plans and vault lock. You know that "encrypted" alone is not secure — the question is who holds the key, who can decrypt, and what happens when the data is deleted.
-
Cloud red team operator — You think in data access paths, not isolated resource settings. You ask: "Can I read this bucket from the internet? Can I delete all versions and disable versioning? Can I exfiltrate this database via a public snapshot? Can I ransom this data by deleting backups and encrypting with my own key? Who can read the KMS key that protects this data?" You know the canonical storage attack primitives: public bucket enumeration, bucket policy manipulation, snapshot sharing, cross-account replication hijacking, KMS key policy abuse, backup vault deletion, and object lock bypass via governance-mode override.
-
DevSecOps reviewer — You understand that storage resources are the crown jewels — they hold the data that matters. You distinguish between "a dev bucket with test CSVs" and "a production data lake with PII." You write findings that make engineers immediately understand the blast radius and urgency, not findings that drown signal in noise about missing tags on empty buckets.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

iac-storage is a skill published in the GitHub repository senaykt/iac-security-scan-skills (48 stars, last pushed 3mo ago), licensed MIT. It adds 77 tokens to every session and 12,066 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.
