Test it

Using "aws-cost-optimizer". Compare this month with last month and identify the main cost drivers.

Expected outcome:

  • EC2 increased by 18 percent and contributed the largest absolute change.
  • Data transfer increased by 11 percent, concentrated in one region.
  • Validate deployment growth and cross-region traffic before changing resources.

Using "aws-cost-optimizer". Find quick savings opportunities without changing resources.

Expected outcome:

  • Seven unattached EBS volumes are candidates for owner review.
  • Three Elastic IPs have no current association.
  • Keep the assessment read-only until owners approve each action.

Using "aws-cost-optimizer". Prepare a rightsizing summary for leadership.

Expected outcome:

The review identifies prioritized EC2 and RDS candidates, estimated savings, supporting utilization metrics, operational risks, and approval steps.

Security Audit

Medium Risk
v5 • 7/23/2026 Open versioned report

All 23 static findings are false positives caused by Markdown fences, fixed date substitutions, JMESPath backticks, or links to official AWS documentation. The skill still presents a medium-risk operational concern because its workflow recommends destructive AWS actions that require explicit approval and environment-specific validation.

Potential Destructive AWS Resource Actions
The workflow recommends deleting volumes and snapshots, releasing addresses, and stopping or terminating instances. It also offers deletion-script generation, which could cause data loss or outages without explicit approval.
The cited prose explicitly names deletion, release, stop, and termination actions. Later safety notes reduce risk but do not require an approval gate.

What You Can Build

Review Monthly Cloud Spend

Compare recent AWS costs by service and identify the largest spending increases.

Find Idle Infrastructure

Inventory unused storage, addresses, snapshots, and low-utilization compute before a cleanup review.

Prepare a Savings Roadmap

Turn usage evidence into prioritized actions, estimated savings, and a leadership summary.

Try These Prompts

Summarize AWS Costs 
Analyze read-only AWS costs for the last three months. Break down spending by service and highlight the five largest month-over-month changes.
Inventory Idle Resources 
Find unattached EBS volumes, unused Elastic IPs, and snapshots older than 90 days. Return resource identifiers, regions, age, and estimated monthly savings.
Assess Compute Rightsizing 
Review 30 days of EC2 and RDS utilization. Recommend rightsizing candidates with evidence, expected savings, performance risks, and validation steps.
Build an Optimization Roadmap 
Create a 90-day AWS cost optimization roadmap. Rank actions by savings, effort, and risk. Require approval before any resource change.

Best Practices

  • Start with read-only permissions and preserve the evidence used for each recommendation.
  • Confirm ownership, backups, dependencies, and rollback plans before changing any resource.
  • Validate savings estimates against current pricing and review results after implementation.

Avoid

  • Do not delete, stop, or resize resources based only on low utilization.
  • Do not purchase commitments without stable usage history and coverage analysis.
  • Do not expose account identifiers, resource names, or cost reports beyond authorized recipients.

Frequently Asked Questions

What AWS access does this skill need?
It needs configured AWS CLI credentials and read access to Cost Explorer, resource inventories, and relevant CloudWatch metrics.
Does the skill change AWS resources automatically?
The documented analysis commands are read-only. Any generated mutation command requires separate review, explicit approval, and suitable AWS permissions.
Can it estimate potential savings?
Yes. Estimates depend on current pricing, usage history, resource metadata, and the completeness of available metrics.
Which resources can it review?
It covers EC2, EBS, Elastic IPs, snapshots, RDS, S3 lifecycle opportunities, Lambda memory, logs, and commitment options.
Will every example command work on macOS?
No. Several examples use GNU date options, so macOS users may need compatible date syntax or GNU core utilities.
How should recommendations be validated?
Review workload dependencies, ownership, backups, performance requirements, pricing, and rollback plans before implementing any recommendation.
