Available Skills

The CloudZero Cost Analyst plugin includes 8 AI-powered skills that Claude automatically uses based on your questions:

1. Cost Spike Investigation

Triggered by: "What caused the cost spike?", "Why did costs increase?", "Investigate cost jump"

Analyzes sudden cost increases by comparing recent spending to baselines and identifying which services, accounts, or resources are responsible.

Example:

"Our AWS costs spiked last week. Can you investigate what happened?"

2. Top Cost Drivers

Triggered by: "What are my biggest costs?", "Show top spending", "Where is money going?"

Identifies and ranks the highest cost contributors across services, accounts, teams, and regions to prioritize optimization efforts.

Example:

"What are my top 10 cost drivers this month?"

3. Cost Trend Analysis

Triggered by: "How are costs trending?", "Show cost growth", "Forecast spending"

Analyzes cost trends over time to identify patterns, growth rates, seasonality, and forecast future spending.

Example:

"Analyze my cost trends over the last 90 days and forecast next month"

4. Cost Comparison

Triggered by: "Compare costs between...", "Production vs staging costs", "This month vs last month"

Compares costs across time periods, environments, accounts, regions, or teams to understand variations and benchmark efficiency.

Example:

"Compare production costs to staging and development environments"

5. Service Cost Deep Dive

Triggered by: "Analyze EC2 costs", "Deep dive into RDS", "Break down S3 spending"

Performs detailed analysis of specific cloud services, breaking down by usage types, resources, regions, and identifying optimization opportunities.

Example:

"Do a deep dive on our EC2 costs and identify optimization opportunities"

6. Tag Coverage Analysis

Triggered by: "Check tag coverage", "Show untagged resources", "Tagging quality"

Evaluates tagging quality and coverage to identify untagged resources, calculate coverage percentages, and improve cost allocation.

Example:

"What's our tag coverage and which resources are untagged?"
