aws-cloudformation-cloudfront

Provides AWS CloudFormation patterns for CloudFront distributions, origins (ALB, S3, Lambda@Edge, VPC Origins), CacheBehaviors, Functions, SecurityHeaders, parameters, Outputs and cross-stack references. Use when creating CloudFront distributions with CloudFormation, configuring multiple origins, implementing caching strategies, managing custom domains with ACM, configuring WAF, and optimizing performance.

Quality

Content

78%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.

Well-structured, actionable content with executable CloudFormation examples, a clear numbered workflow with a validation checkpoint, and excellent progressive disclosure via clearly labeled reference files. The main improvements are tighter validation feedback loops and trimming redundant best-practice/related-resource lists.

Suggestions

Add an explicit validate->fix->re-validate feedback loop (e.g., 'If cfn-lint fails, fix errors and re-run before deploying') to push workflow clarity toward 5.

Consolidate the 'Best Practices' bullet lists, which overlap with the inline examples and reference files, to reduce redundancy and token cost.

Prune the 'Related Resources' link list to the most authoritative two or three, or move it into a reference file, to improve conciseness.

DimensionReasoningScore

Conciseness

The body is mostly efficient with executable YAML snippets and tight best-practice lists; a few sections (Best Practices, Related Resources) repeat information already in the examples and could be trimmed, but it largely assumes Claude's competence.

4 / 5

Actionability

It provides concrete, copy-paste-ready CloudFormation YAML and validation commands ('aws cloudformation validate-template', 'cfn-lint') covering common cases; minor gaps exist (e.g., some snippets omit surrounding resource context).

4 / 5

Workflow Clarity

An 8-step numbered workflow with an explicit 'Validate before deploying' checkpoint and a change-set/deployment guidance is clearly sequenced with most checkpoints present; it lacks a full validate->fix->retry feedback loop, keeping it just below 5.

4 / 5

Progressive Disclosure

SKILL.md is a clear overview with well-signaled one-level-deep references to real bundle files (template-structure.md, origins.md, caching.md, security.md, advanced-features.md, constraints.md), each clearly labeled by topic, matching the top anchor.

Description

83%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 strong, specific description that clearly states both what the skill provides and when to use it, with concrete trigger phrases and a distinct CloudFront+CloudFormation niche. Minor tightening of synonyms and reducing the long capability list could nudge it higher.

Suggestions

Trim the long parenthetical capability list in the 'what' clause to the highest-value items to reduce verbosity and improve scannability.

Add natural synonyms users might say (e.g., 'CDN', 'edge', 'static site', 'content delivery') to broaden trigger-term coverage.

Consider an even sharper 'Use when...' clause focused on the most common intent to further reduce overlap with adjacent AWS skills.

DimensionReasoningScore

Specificity

The description lists several concrete capabilities (CloudFront distributions, origins like ALB/S3/Lambda@Edge, CacheBehaviors, Functions, SecurityHeaders, parameters, Outputs, cross-stack references) with only minor coverage gaps, matching the 'several specific actions' anchor.

4 / 5

Completeness

It explicitly states both the 'what' ('Provides AWS CloudFormation patterns for CloudFront distributions, origins...') and the 'when' via an explicit 'Use when...' clause with concrete trigger phrases, matching the top anchor.

5 / 5

Trigger Term Quality

It surfaces natural user phrasing such as 'creating CloudFront distributions with CloudFormation', 'configuring multiple origins', 'managing custom domains with ACM', and 'configuring WAF'; a few natural synonyms are missing but coverage is strong.

4 / 5

Distinctiveness Conflict Risk

The CloudFormation+CloudFront niche is clearly distinct with specific trigger phrases; minor overlap risk exists with adjacent AWS/CDN skills, so it sits between anchors 4 and 5.
