Quality

Content

68%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.

A well-structured, actionable skill body with a concrete template and targeted commands. It is held back by a flat instruction list lacking an explicit validation feedback loop and by single-example coverage of a multi-topic domain.

Suggestions

Add a short sequenced workflow with an explicit validate -> fix -> re-validate feedback loop for stack updates, since CloudFormation updates are destructive and the rubric caps workflow_clarity at 3 without one.

Add one more executable example covering nested stacks or drift detection to close the coverage gap and lift actionability.

Remove the redundancy between Instructions (#3/#6) and the Best Practices do/don't list, or collapse one into the other, to tighten conciseness.

DimensionReasoningScore

Conciseness

Lean body that avoids explaining CloudFormation basics, with only minor redundancy: the intro role line and the Best Practices do/don't list restate instructions #3 and #6.

4 / 5

Actionability

Provides a copy-paste-ready VPC template and specific commands (validate-template, continue-update-rollback --resources-to-skip), but only one example leaves gaps for nested stacks and drift detection.

4 / 5

Workflow Clarity

Instructions are a flat best-practice list rather than a sequenced workflow; a validate-template checkpoint exists but there is no validate->fix->retry feedback loop, and the destructive-stack-update cap at 3 applies.

3 / 5

Progressive Disclosure

No bundle files exist, but the single-file body is self-contained and well-organized with clear section headers; the inline full template is borderline content that could optionally live in a reference.

Description

71%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.

A concise, third-person description that clearly states both capabilities and a use-trigger, with a distinct CloudFormation niche. It could improve trigger-term coverage with more natural synonyms and broaden the 'when' clause.

DimensionReasoningScore

Specificity

Names the CloudFormation domain and several concrete actions ('template optimization, nested stacks, drift detection, and production-ready patterns'), with only minor coverage gaps relative to the comprehensive 5 anchor.

4 / 5

Completeness

Provides a clear 'what' (optimization, nested stacks, drift detection, production patterns) and an explicit 'Use when writing or reviewing CF templates' clause, but the trigger is single and could be more specific.

4 / 5

Trigger Term Quality

Includes relevant terms 'CloudFormation' and 'CF templates' but misses common natural variations users would say such as 'stack', 'IaC', or 'infrastructure as code'.

3 / 5

Distinctiveness Conflict Risk

Occupies a clear CloudFormation-specific niche with distinct triggers and minimal overlap risk with other skills.
