cost-optimization
Optimize cloud costs through resource rightsizing, tagging strategies, reserved instances, and spending analysis. Use when reducing cloud expenses, analyzing infrastructure costs, or implementing cost governance policies.

Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a well-crafted skill description that follows best practices. It uses third person voice, lists specific concrete capabilities, includes a clear 'Use when...' clause with natural trigger terms, and carves out a distinct niche around cloud cost optimization that differentiates it from general cloud infrastructure skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'resource rightsizing, tagging strategies, reserved instances, and spending analysis' - these are distinct, actionable capabilities rather than vague language. | 3 / 3 |
Completeness | Clearly answers both what ('Optimize cloud costs through resource rightsizing, tagging strategies, reserved instances, and spending analysis') and when ('Use when reducing cloud expenses, analyzing infrastructure costs, or implementing cost governance policies') with explicit trigger guidance. | 3 / 3 |
Trigger Term Quality | Includes natural keywords users would say: 'cloud costs', 'cloud expenses', 'infrastructure costs', 'cost governance', 'rightsizing', 'reserved instances' - good coverage of terms a user seeking cost optimization would naturally use. | 3 / 3 |
Distinctiveness Conflict Risk | Clear niche focused specifically on cloud cost optimization with distinct triggers like 'rightsizing', 'reserved instances', 'cost governance' - unlikely to conflict with general cloud or infrastructure skills due to the specific cost/financial focus. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a comprehensive cloud cost optimization skill with strong actionability through executable Terraform examples and good progressive disclosure. The main weaknesses are moderate verbosity in the framework sections and lack of validation/verification workflows to confirm cost optimizations are working as expected.
Suggestions
Add a validation workflow showing how to verify cost savings after implementing changes (e.g., 'After applying reserved instances, verify in Cost Explorer that savings appear within 24-48 hours')
Condense the 'Purpose' and 'When to Use' sections or remove them entirely since they duplicate the skill description
Add a feedback loop for the optimization checklist showing how to measure before/after costs and rollback procedures if performance is impacted
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is reasonably efficient but includes some unnecessary framing (e.g., 'Purpose' and 'When to Use' sections that largely repeat the description). The framework sections are somewhat verbose with bullet lists that could be more condensed. | 2 / 3 |
Actionability | Provides fully executable Terraform/HCL code examples for S3 lifecycle policies, budget alerts, auto-scaling, and tagging. The code is copy-paste ready with realistic configurations and specific values. | 3 / 3 |
Workflow Clarity | The checklist at the end provides a sequence of actions, but there are no validation checkpoints or feedback loops for verifying cost optimization changes. Missing guidance on how to verify savings were achieved or rollback if performance degrades. | 2 / 3 |
Progressive Disclosure | Well-organized with clear sections, references to external files (tagging-standards.md, cost-analysis-template.xlsx), and related skills. Content is appropriately structured with quick reference tables and detailed code examples separated logically. | 3 / 3 |
Total | 10 / 12 Passed |
