aws-wa-sustainability

aws-wa-sustainability is a skill for Claude Code, Codex from roboco-io/plugins. It costs 31 tokens per session (1,292 once invoked), scanned A, original, MIT.

An AWS sustainability review for infrastructure-as-code (IaC), the files that define cloud resources. It checks energy use, resource efficiency, hardware choices, serverless services, managed services, and data transfer.

In plain words
What is it for?
Use it to review Graviton instances, Lambda, Fargate, Aurora Serverless, DynamoDB on-demand, managed services, and data-transfer optimization.
Why use it?
It helps identify infrastructure choices that may use more energy or resources than necessary.

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

aws-wa-sustainability 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.

Sustainability Pillar

환경 영향 최소화, 에너지 효율 관점에서 IaC 코드를 검토합니다.

핵심 원칙

  1. 영향 이해: 탄소 발자국 측정
  2. 지속 가능성 목표 수립: 환경 목표 설정
  3. 활용 극대화: 리소스 효율성 최대화
  4. 더 효율적인 하드웨어/소프트웨어 채택: Graviton, Serverless
  5. 관리형 서비스 사용: 공유 인프라 활용
  6. 다운스트림 영향 축소: 데이터 전송 최적화

검토 항목

SUS-01: Graviton 인스턴스 사용

심각도 탐지 유형
Low 자동 탐지

검토 내용: 에너지 효율적인 Graviton 프로세서 사용 여부

Graviton 장점:

  • 최대 60% 에너지 효율 향상
  • 동일 성능 대비 낮은 비용

Terraform 패턴:

# 권장 - Graviton 인스턴스
resource "aws_instance" "sustainable" {
  instance_type = "t4g.medium"  # Graviton2
}

resource "aws_instance" "sustainable_v3" {
  instance_type = "m7g.large"   # Graviton3
}

SUS-02: Serverless 활용

심각도 탐지 유형
Low 자동 탐지

검토 내용: Lambda, Fargate 등 서버리스 서비스 활용 여부

권장 서비스:

  • AWS Lambda
  • AWS Fargate
  • Amazon Aurora Serverless
  • Amazon DynamoDB On-Demand

Terraform 패턴:

# 권장 - Lambda 사용
resource "aws_lambda_function" "sustainable" {
  function_name = "my-function"
  runtime       = "python3.11"
  # 사용하지 않을 때 리소스 소비 없음
}

# 권장 - Fargate 사용
resource "aws_ecs_service" "sustainable" {
  launch_type = "FARGATE"
}

SUS-03: 관리형 서비스 활용

심각도 탐지 유형
Low 자동 탐지

검토 내용: 자체 관리 대신 관리형 서비스 사용 여부

  • Amazon RDS (vs 자체 관리 DB)
  • Amazon ElastiCache (vs 자체 관리 Redis)
  • Amazon OpenSearch Service
  • Amazon MQ

SUS-04: 리소스 적정 규모

심각도 탐지 유형
Low 자동 탐지

  • us-west-2 (Oregon)
  • ca-central-1 (Canada)

SUS-06: 미사용 리소스 정리

SUS-07: 데이터 저장 최적화

심각도 탐지 유형
Low 자동 탐지

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.

Changes

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.
