SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Investigating AWS spend anomalies and proposing cost optimizations is risky because billing data is delayed, estimated, and sensitive, and premature changes to resources, budgets, or commitments can cause outages or financial lock-in. This Skill enforces a read-only, evidence-first workflow before any cost-related change. ## Core Features & Use Cases - Read-only cost baseline: Verifies account identity and billing scope, then queries Cost Explorer or CUR with documented metrics, time windows, and groupings. - Evidence-backed recommendations: Separates observations from interventions, requiring utilization, SLO, and allocation evidence before suggesting rightsizing, tagging fixes, or commitment purchases. - Approval gates for changes: Requires explicit confirmation and a structured risk/verification/rollback plan before modifying budgets, IAM, exports, resources, or Savings Plans/Reserved Instances. - Use Case: When a monthly AWS bill spikes unexpectedly, use this Skill to identify the accountable account scope, reproduce the anomaly with a bounded Cost Explorer query, and present a verified recommendation with rollback criteria instead of deleting resources on cost data alone. ## Quick Start Use the aws-finops skill to investigate why our AWS spend increased last month and propose safe optimization options.

FAQPage Schema
How do I investigate an unexpected AWS cost spike?

Start read-only: confirm the account and billing scope with aws sts get-caller-identity, then query Cost Explorer with a bounded date range, explicit metric, and service grouping. Compare like-for-like periods and record data freshness before attributing a cause.

How to analyze AWS costs with Cost Explorer and CUR?

Use Cost Explorer for grouped daily or monthly cost and usage trends, noting that the End date is exclusive and API calls can incur charges. For resource-level attribution, query the approved Cost and Usage Report in its S3 bucket with least-privilege access.

Can I rightsize or delete AWS resources based on cost data alone?

No. Cost data alone is insufficient; recommendations require utilization over a representative period, workload schedule, SLO headroom, dependencies, and a recovery method. Any stop, resize, or deletion needs explicit owner approval and a rollback plan.

What should I check before buying Savings Plans or Reserved Instances?

Verify eligible usage history, coverage and utilization, term and payment option, break-even assumptions, and account allocation. Commitment purchases require explicit approval since they create financial lock-in that a utilization graph alone cannot justify.

Why is current-month AWS cost data unreliable for decisions?

Current-month cost and usage figures are estimates that AWS can revise, and billing data arrives with delay. Always record the query scope, time window, metric, and freshness, and avoid claiming savings or root cause until data is final.
