finops

finops is a skill for Claude Code from pwdev-solucoes/pwdev-claude-marketplace. It costs 83 tokens per session (756 once invoked), scanned A, original, Apache-2.0.

A guide to examining AWS spending and finding unused or oversized resources. AWS is Amazon's cloud platform, and FinOps is the practice of managing cloud costs with usage and operational data.

In plain words
What is it for?
Use it to review Cost Explorer data and inspect EC2, RDS, S3, EKS, EBS, NAT Gateway, Elastic IP, snapshots, and CloudWatch Logs costs.
Why use it?
It helps explain rising bills by checking for idle storage, unused addresses, oversized services, forgotten environments, and logs without retention settings. Most of its checks are read-only.

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

finops 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 6d 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.

FinOps

Você encontra dinheiro parado. É o domínio de maior retorno e menor risco: quase tudo aqui é describe.

Princípio central

Custo alto raramente é preço errado. É recurso ocioso, superdimensionado ou esquecido.

Os 8 desperdícios clássicos

Verifique nesta ordem — a de cima costuma render mais.

# Desperdício Como achar
1 NAT Gateway por AZ com pouco tráfego custo por hora × 3 AZs soma rápido
2 EBS órfão (available) describe-volumes --filters Name=status,Values=available
3 Snapshot antigo sem política describe-snapshots --owner-ids self
4 Elastic IP não associado describe-addresses sem AssociationId
5 EC2/RDS superdimensionado CloudWatch CPU < 10% por 14 dias
6 S3 sem lifecycle objeto antigo em Standard em vez de IA/Glacier
7 Ambiente dev ligado 24/7 agendar parada fora do horário
8 Log sem retenção CloudWatch Logs sem retentionInDays

Relatório

Custo do período: {{valor}} — variação: {{%}}
Top 5 serviços: {{lista}}

| Achado | Economia estimada/mês | Esforço | Risco |
|---|---|---|---|

Só afirme economia quando puder mostrar a conta. Estimativa sem base vira promessa que não se cumpre. Sem dado suficiente, escreva [VERIFICAR: preço unitário].

Antes de recomendar remoção

Todo recurso "órfão" pode ter dono. Antes de propor exclusão:

  • verifique tags de dono e projeto
  • verifique se é backup ou dependência de DR
  • pergunte a quem pertence

Volume "não usado" que era o snapshot de DR é o erro caro deste domínio.

Limites

  • Não exclui recurso — entrega a lista e o comando, quem executa é o humano
  • Não altera reserva, Savings Plan nem compromisso financeiro
  • Não acessa faturamento fora do que a credencial já permite
  • Não promete economia sem a conta que a sustenta

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.
