aws-cloudformation-elasticache

Provides AWS CloudFormation patterns for Amazon ElastiCache. Use when creating ElastiCache clusters (Redis, Memcached), replication groups, parameter groups, subnet groups, and implementing template structure with Parameters, Outputs, Mappings, Conditions, and cross-stack references for distributed caching infrastructure.

Quality

Content

38%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 comprehensive on ElastiCache specifics but bloated with general CloudFormation primer material that duplicates the reference bundle, and several examples use invalid resource type names. The workflow lacks integrated validation checkpoints and the in-body reference links are broken.

Suggestions

Move the general CloudFormation template-structure primer (Parameters, Mappings, Conditions, Transform, Outputs sections) into references/reference.md and keep SKILL.md as a concise overview with one-level-deep links.

Fix the resource type names throughout the examples (AWS::ElastiCache::Cluster -> AWS::ElastiCache::CacheCluster, AWS::ElastiCache::Cluster::Id -> AWS::ElastiCache::CacheCluster::Id) and correct the broken EXAMPLES.md/REFERENCE.md links to references/examples.md and references/reference.md.

Integrate validation as an explicit checkpoint in the Instructions workflow (e.g., run cfn-lint after drafting, only deploy when validation passes) rather than leaving it in a separate section.

DimensionReasoningScore

Conciseness

The 1339-line body extensively explains general CloudFormation concepts Claude already knows (template sections, AWSTemplateFormatVersion, Description, Metadata, Mappings, Conditions, Transform, Outputs) and inlines large reference tables that duplicate references/reference.md, making it noticeably verbose and padded rather than lean.

2 / 5

Actionability

Many concrete YAML examples are provided, but a meaningful share use incorrect resource type names (AWS::ElastiCache::Cluster appears repeatedly instead of the valid AWS::ElastiCache::CacheCluster, and AWS::ElastiCache::Cluster::Id parameter types), so several examples are not copy-paste valid as written.

3 / 5

Workflow Clarity

An 8-step Instructions sequence exists and a separate 'Validate Before Deployment' section is present, but the main workflow has no validation checkpoints or error-feedback loops; because provisioning ElastiCache is a destructive/batch operation, the rubric caps this at 3.

3 / 5

Progressive Disclosure

Although references/examples.md and references/reference.md exist, the SKILL.md body inlines ~1000 lines of material that clearly belongs in those files, and the final navigation links point to EXAMPLES.md/REFERENCE.md without the references/ prefix, so they are broken while content that should be external is inlined.

Description

90%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 well-crafted: third-person voice, explicit 'Use when' trigger, and a comprehensive, concrete list of capabilities scoped tightly to ElastiCache on CloudFormation. The only minor gap is a lack of synonym/extension variants for trigger terms.

DimensionReasoningScore

Specificity

Lists multiple concrete capabilities — 'creating ElastiCache clusters (Redis, Memcached), replication groups, parameter groups, subnet groups' plus 'template structure with Parameters, Outputs, Mappings, Conditions, and cross-stack references' — giving comprehensive, specific coverage rather than vague language.

5 / 5

Completeness

Explicitly answers both 'what' ('Provides AWS CloudFormation patterns for Amazon ElastiCache') and 'when' ('Use when creating...') with concrete trigger phrases, matching the 5 anchor.

5 / 5

Trigger Term Quality

Strong natural terms ('ElastiCache clusters', 'Redis, Memcached', 'replication groups', 'CloudFormation', 'distributed caching infrastructure') that users would actually say, but missing common synonyms and shorthand variants that would push it to a 5.

4 / 5

Distinctiveness Conflict Risk

Clearly niched to ElastiCache CloudFormation with distinct triggers (Redis/Memcached clusters, replication groups, subnet groups); minimal risk of firing for an unrelated skill.
