aws-cost-optimization

AWS cost optimization and FinOps workflows. Use this skill whenever the user mentions AWS costs, cloud spending, FinOps, Reserved Instances, Savings Plans, or cost reduction. Triggers include finding unused resources, analyzing the AWS bill, rightsizing EC2 or RDS instances, evaluating Spot instances, detecting cost anomalies, migrating to Graviton or newer instance generations, implementing tagging for cost allocation, setting up AWS Budgets, conducting monthly cost reviews, comparing RI vs Savings Plans, and optimizing storage, network, or database costs.

Quality

Content

76%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is highly actionable with copy-paste AWS CLI commands and well-signaled one-level references to real bundle files, but it carries minor redundancy and, critically, its destructive workflows lack explicit validation checkpoints, capping workflow clarity at 3.

Suggestions

Add an explicit validation checkpoint before destructive actions in Workflow 1 — e.g. a 'Step 4: Validate findings before deletion' step that cross-references ownership/tags and confirms snapshots have backups elsewhere — to lift the workflow_clarity cap.

Remove or consolidate the duplicated command listings and savings percentages between the Quick Reference, Service-Specific Optimization, and the workflows to tighten conciseness.

Fix time-sensitive values such as the hardcoded '2025-01-01' snapshot filter (use a computed date) so the examples remain executable and do not decay.

DimensionReasoningScore

Conciseness

The body is largely lean, copy-paste AWS CLI commands with minimal concept explanation, but the Quick Reference and Service-Specific Optimization sections repeat commands and savings figures already shown in the workflows — minor trimmable redundancy rather than padding.

4 / 5

Actionability

Commands are concrete and runnable (with reasonable placeholders like INSTANCE_ID and --region), and specific examples cover the common cases across unused resources, cost anomalies, rightsizing, RI/SP analysis, generation migration, Spot, and troubleshooting.

5 / 5

Workflow Clarity

Steps are sequenced, but the destructive 'Implement' step ('Delete unused resources…') lacks an explicit validate-before-destroy checkpoint in the main workflow; per the rubric's destructive/batch cap, implicit-only validation keeps this at 3 even though some verification notes appear in Troubleshooting and the checklist.

3 / 5

Progressive Disclosure

Real bundle files (references/best_practices.md, references/service_alternatives.md, references/finops_governance.md, assets/templates/monthly_cost_report.md) are referenced one level deep with consistent 'See references/… → section' signaling; structure is good, though the ~480-line body is somewhat long for an overview and a few inline sections duplicate referenced material.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is exemplary: it states the skill's purpose, gives an explicit 'Use this skill whenever…' trigger clause, and enumerates both natural user keywords and concrete capabilities. It is comprehensive without becoming vague.

DimensionReasoningScore

Specificity

Lists many concrete actions — 'finding unused resources, analyzing the AWS bill, rightsizing EC2 or RDS, evaluating Spot instances, detecting cost anomalies, migrating to Graviton… optimizing storage, network, or database costs' — giving comprehensive coverage of the domain.

5 / 5

Completeness

Explicitly answers both 'what' ('AWS cost optimization and FinOps workflows') and 'when' ('Use this skill whenever the user mentions… Triggers include…') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Covers natural user phrases including synonyms and product names — 'AWS costs, cloud spending, FinOps, Reserved Instances, Savings Plans, cost reduction' plus 'AWS bill' — matching the comprehensive-coverage anchor.

5 / 5

Distinctiveness Conflict Risk

A clear, AWS-specific FinOps niche with AWS-only trigger terms, giving minimal overlap risk with other skills; voice is third-person ('Use this skill…').
