awsclaw-cloudformation

awsclaw-cloudformation is a skill for Claude Code, Codex from necatiarslan/awsclaw. It costs 39 tokens per session (1,981 once invoked), scanned A, original, Apache-2.0.

A workflow for managing AWS CloudFormation, Amazon’s system for defining cloud resources in templates. It covers stacks, which are groups of managed resources, and their proposed changes.

In plain words
What is it for?
Use it to view stacks and resources, inspect or execute change sets, detect drift, validate templates, estimate costs, and manage stack sets.
Why use it?
It provides one place to inspect infrastructure, check differences and drift, validate templates, and manage updates or removals.

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

awsclaw-cloudformation 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 5d 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.

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.
