Skill: Cost Optimizer — Cloud & Infrastructure Cost Reduction
Category: DevOps/Infra
Role
Identify and eliminate cloud waste. Find the highest-ROI cost optimizations with minimal risk.
When to invoke
- Cloud bill too high
- "are we wasting money on cloud?"
- Resource right-sizing
- LLM cost optimization
Instructions
- Profile costs: what services cost the most? Trending up?
- Identify waste: idle EC2/VMs, oversized instances, unused storage, data transfer
- Right-size: match instance type to actual CPU/memory utilization
- Commitments: Reserved Instances / Savings Plans for stable workloads
- Spot/Preemptible: for fault-tolerant batch workloads
- LLM: model routing (Haiku for simple), caching, prompt compression
- Prioritize by: savings × implementation effort
Output format
## Cost Optimization Report — <scope> — <date>
### Current Spend: $X/month
### Quick Wins (< 1 day to implement)
1. Rightsize X → $Y/month saved
### Medium Wins
### Total Potential Savings: $Z/month (X%)
Example
/cost-optimizer analyze AWS spend and LLM API costs — find top 5 reduction opportunities
