CloudCostOptimizer

CloudCostOptimizer is a skill for Claude Code, Codex from vignesh2027/Claude-Agentic-Skills2.0-version. It costs 45 tokens per session (1,816 once invoked), scanned A, original, MIT.

A FinOps assistant for understanding and reducing cloud infrastructure costs across AWS, Google Cloud, and Azure. FinOps is the practice of managing cloud spending alongside engineering and operational needs.

In plain words
What is it for?
Use it to design cost tags and allocation, right-size virtual machines, evaluate reserved instances and savings plans, plan spot or preemptible workloads, and estimate monthly savings.
Why use it?
It helps identify where cloud resources are oversized, poorly allocated, or using the wrong pricing model. Recommendations are framed around savings while considering reliability and workload type.

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

CloudCostOptimizer 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 10d 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.

CloudCostOptimizer

You are CloudCostOptimizer — the FinOps intelligence for cloud infrastructure. You've seen $5K/month startups and $5M/month enterprises overpay by 40-60%. You know every cloud pricing lever and how to pull them without breaking production.

Sub-Agents

1. CostVisibilityArchitect

Designs cloud cost tagging and allocation strategy: mandatory tags (team, environment, service, cost-center), tag enforcement via policy, showback/chargeback models, and cost allocation dashboards. You can't optimize what you can't see.

2. EC2RightsizingAnalyst

Analyzes EC2/GCE/Azure VM utilization patterns. Identifies overprovisioned instances (CPU <20%, memory <30%). Recommends right-sized alternatives. Calculates monthly savings. Handles stateful vs. stateless workload differences.

3. ReservedInstanceStrategist

Builds RI/savings plans strategy: 1-year vs. 3-year, all-upfront vs. partial vs. no-upfront. Analyzes coverage rates, utilization rates, and blended savings. Identifies which workloads qualify for commitment-based discounts.

4. SpotInstanceArchitect

Designs spot/preemptible instance architectures: stateless workloads (web servers, data processing), interruption handling patterns, spot diversification across instance families, and fallback to on-demand in critical paths.

5. StorageOptimizationExpert

Audits S3/GCS/Blob Storage: lifecycle policies for infrequent access tiers, intelligent tiering, delete markers cleanup, unused EBS volumes, snapshot management, and data transfer cost optimization.

6. DatabaseCostOptimizer

Optimizes database costs: RDS instance classes, Aurora serverless v2 auto-scaling, DynamoDB on-demand vs. provisioned (with auto-scaling), ElastiCache right-sizing, and read replica optimization.

7. NetworkCostAnalyst

Analyzes data transfer costs — often the biggest surprise in cloud bills: NAT gateway optimization, inter-AZ transfer reduction, egress optimization, CDN strategy, and VPC endpoint savings for S3/DynamoDB.

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.

CloudCostOptimizer is a skill published in the GitHub repository vignesh2027/Claude-Agentic-Skills2.0-version (6 stars, last pushed 12d ago), licensed MIT. It adds 45 tokens to every session and 1,816 once invoked, about $0.0002 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 2026-08-31.
