Quality

Content

71%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 highly actionable EKS reference with copy-paste-ready commands and a clear checkpoint in the cluster workflow. Its main weaknesses are explaining basics Claude already knows plus hardcoded time-sensitive version numbers, and a monolithic structure that would benefit from splitting detail into bundle files.

Suggestions

Move hardcoded add-on version strings out of the main examples or into a separately maintained reference, since time-sensitive versions penalize conciseness when inlined.

Trim introductory explanations of what EKS/Kubernetes is and what the control plane runs, as Claude already knows these concepts.

Split the CLI Reference and Troubleshooting sections into separate bundle files (e.g. references/cli.md, references/troubleshooting.md) and link to them from SKILL.md to improve progressive disclosure.

Dimension	Reasoning	Score
Conciseness	Mostly efficient command/code blocks, but it restates basics Claude knows ('runs Kubernetes without installing and operating your own control plane') and hardcodes time-sensitive addon versions (e.g. 'v1.11.1-eksbuild.4') inline rather than in a deprecated section, triggering the version-number penalty.	3 / 5
Actionability	Fully executable, copy-paste-ready aws/eksctl/kubectl commands and YAML covering cluster creation, node groups, IRSA, add-ons, deployment, and troubleshooting across the common cases.	5 / 5
Workflow Clarity	Sequenced patterns with a real checkpoint ('aws eks wait cluster-active --name my-cluster'), but no explicit validate-then-fix-then-retry feedback loops, leaving minor validation gaps versus the top anchor.	4 / 5
Progressive Disclosure	Well-structured with a TOC, headers, and external doc links, but it is a ~390-line monolith with CLI reference tables and troubleshooting inlined and no bundle-file references to split detail into.	3 / 5

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, well-structured description that concretely states both capabilities and explicit use-when triggers for EKS. It is held back from the top tier only by minor keyword/synonym gaps and a slightly broad trailing clause.

Dimension	Reasoning	Score
Specificity	Lists several concrete actions ('creating clusters, configuring IRSA, managing node groups, deploying applications') but the lead 'management' is generic and scaling/upgrading are absent, leaving minor coverage gaps versus the comprehensive anchor.	4 / 5
Completeness	Explicitly answers both what ('AWS EKS Kubernetes management for clusters, node groups, and workloads') and when ('Use when creating clusters, configuring IRSA...') with concrete trigger phrases.	5 / 5
Trigger Term Quality	Good natural keyword coverage ('clusters', 'node groups', 'workloads', 'IRSA', 'deploying applications') that users would say, but missing common synonyms like 'kubectl' or 'EKS cluster' needed for the comprehensive anchor.	4 / 5
Distinctiveness Conflict Risk	The 'AWS EKS Kubernetes' niche is distinct with clear triggers, but the trailing 'integrating with AWS services' is broad and creates minor overlap risk with other AWS skills.	4 / 5
