How does this skill detect cost anomalies?

It utilizes specific rules such as daily spend spikes (>20% vs 7-day average) and service cost jumps to flag unusual activity, followed by a structured investigation template to identify the root cause.

Does this skill automate the cost-cutting process?

The skill provides the analysis, risk assessment, and implementation planning. It is designed to assist engineers in making informed decisions rather than making blind, automated cuts that could impact performance.

Can I use this for reserved capacity planning?

Yes, it includes a dedicated analysis phase for Reserved Instances (RIs) that evaluates current coverage, identifies purchase opportunities, and calculates break-even periods.

What cloud providers does this skill support?

While the provided templates use AWS terminology (EC2, RDS, S3), the structured workflow and FinOps principles are designed to be applicable across all major providers including GCP and Azure.
