cost-projection

Project the monthly cost of an infrastructure definition (Terraform, CDK, CloudFormation, SAM) using CloudZero spend data. Reads IaC files, enumerates resources, and produces a line-item cost breakdown.

Quality

Content

75%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 content is highly actionable with concrete commands, MCP calls, and templates organized into a clear 7-phase workflow. Its weakest point is conciseness — the long body could be tightened and some inline detail could move to the referenced files.

Suggestions

Trim redundant 'Goal:' scaffolding and consolidate the auto-discovery find/grep commands to reduce length.

Move the full report template and estimation-formula table into reference files, keeping only a compact example inline, to improve both conciseness and progressive disclosure.

Add an explicit validation checkpoint after Phase 2 (e.g., 'verify inventory is complete before mapping dimensions') to lift workflow clarity toward a 5.

DimensionReasoningScore

Conciseness

The body is mostly action-dense but runs long (~440 lines) with padded 'Goal:' labels, repeated phase scaffolding, and some explanation that could be tightened; it sits at 'mostly efficient but could be tighter'.

3 / 5

Actionability

Provides copy-paste-ready bash find/grep commands, concrete MCP call signatures with parameters, executable WebSearch/WebFetch examples, estimation formulas, and a full report template covering common cases.

5 / 5

Workflow Clarity

Seven phases are clearly sequenced with goals and feedback loops (confirm dimension values exist, ask user for unresolved variables, fall back to estimates on query failure); minor validation gaps keep it just below a 5.

4 / 5

Progressive Disclosure

Good structure with well-signaled, one-level-deep references in 'See Also' and inline (service-mapping.md, best-practices.md, output-examples.md, etc.); the body is fairly long with inline detail (formula table, full report template) that keeps it from a 5.

Description

75%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 specific and distinctive, naming concrete actions and the supported IaC frameworks. Its main weakness is the absence of an explicit 'Use when...' trigger clause, which caps completeness.

Suggestions

Add an explicit 'Use when...' clause with concrete trigger phrases such as 'Use when estimating the cost of a Terraform/CDK/CloudFormation/SAM stack before deployment'.

Include natural user phrasings like 'how much will this cost to run' and common file extensions (.tf, template.yaml) to strengthen trigger-term coverage.

DimensionReasoningScore

Specificity

Names the domain and lists multiple concrete actions — 'Project the monthly cost', 'Reads IaC files', 'enumerates resources', and 'produces a line-item cost breakdown' — giving comprehensive coverage comparable to the anchor-5 example.

5 / 5

Completeness

It clearly answers 'what' the skill does but lacks an explicit 'Use when...' or equivalent trigger clause, which per the judging guidelines caps completeness at 3.

3 / 5

Trigger Term Quality

Good keyword coverage including 'monthly cost', 'infrastructure', and the framework names 'Terraform, CDK, CloudFormation, SAM', but a few natural user phrases (e.g. 'how much will it cost') and file extensions are absent from the description.

4 / 5

Distinctiveness Conflict Risk

It carves a clear niche — projecting IaC cost via CloudZero — with distinct framework-specific triggers and minimal overlap risk with other skills.
