cis-aws-foundations-2.16

cis-aws-foundations-2.16 is a skill for Claude Code, Codex from CyberStrikeus/CyberStrike. It costs 22 tokens per session (1,243 once invoked), scanned A, original, AGPL-3.0.

An AWS security check that verifies computing instances use IAM roles to access AWS resources. AWS is Amazon's cloud platform, and IAM manages identities and permissions.

In plain words
What is it for?
It helps audit whether AWS instances receive resource permissions through instance roles.
Why use it?
It reduces the need to store long-lived access credentials on instances, lowering the risk of exposed keys.

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

cis-aws-foundations-2.16 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 11d 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.

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.
