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.

The content is well-structured with clear progressive disclosure to two real reference files and actionable, specific guidance throughout, including concrete API and security instructions. Its main weakness is redundancy: the cross-account IAM least-privilege guidance is repeated near-verbatim in three sections, which hurts token efficiency.

Suggestions

Consolidate the cross-account IAM guidance (condition keys, least-privilege resource scoping, avoiding * wildcards) into a single section and cross-reference it from 'Cross-Account Support' and 'Troubleshooting' instead of repeating it three times.

Make the Workflow validation checklist an explicit feedback loop (e.g., 'If terminology or positioning is wrong, revise before responding') rather than a passive 'Always validate' list.

Tighten the security sections by removing the duplicated condition-key bullet lists and linking once to a canonical statement of the cross-account trust policy requirements.

DimensionReasoningScore

Conciseness

The body is largely substantive domain knowledge rather than padding, but the cross-account IAM guidance (condition keys aws:SourceArn/aws:SourceAccount/sts:ExternalId, least-privilege scoping, avoiding * wildcards) is repeated near-verbatim across the 'Cross-Account Support', 'Security Considerations', and 'Troubleshooting' sections, which could be tightened by stating it once and cross-referencing.

3 / 5

Actionability

Guidance is concrete and specific for an instruction-only skill: exact terminology rules, a specific API call ('start-plan-execution' from the healthy Region), named IAM condition keys, and precise S3 bucket controls (SSE-KMS, aws:SecureTransport=false deny, MFA Delete); minor gaps remain where some instructions are descriptive rather than directly executable.

4 / 5

Workflow Clarity

The 'Workflow' section gives a clear 4-step sequence (classify, answer from knowledge, search docs if insufficient, format for audience) followed by an explicit 'Always validate' checklist; this is not a destructive/batch operation so no cap applies, but the validation checkpoints are advisory rather than enforced feedback loops, leaving it just below 5.

4 / 5

Progressive Disclosure

The body is an organized overview that clearly signals two one-level-deep references ('Load that reference for any customer-positioning...' -> references/positioning.md, 'Load that reference to attach the right AWS doc...' -> references/doc-links.md), both of which exist as real files, with content appropriately split and easy navigation, matching the 5 anchor.

Description

87%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 strong: it explicitly states both what the skill does and when to use it, with a comprehensive list of specific capability topics and a clear niche that minimizes conflict risk. The main limitation is that the action is expressed as a single generic verb ('Answers questions about') rather than multiple distinct actions, capping specificity and trigger breadth just below the top anchor.

DimensionReasoningScore

Specificity

Lists a comprehensive set of specific capability topics ('architecture, plans, execution blocks, workflows, triggers, active/active vs active/passive, cross-account support, recovery time, dashboards, and customer positioning'), but the action itself is a single generic verb ('Answers questions about') rather than multiple distinct concrete actions, so it sits below the 5 anchor.

4 / 5

Completeness

Explicitly answers both 'what' ('Answers questions about Amazon Application Recovery Controller (ARC) Region switch including...') and 'when' ('Applicable when users ask about ARC Region switch adoption, design, or troubleshooting.') with concrete trigger phrases, matching the 5 anchor.

5 / 5

Trigger Term Quality

Includes natural terms users would say ('ARC Region switch adoption, design, or troubleshooting') plus the product name and many topic keywords, giving good coverage; a few common synonyms or phrasings a user might naturally use are missing, so it does not reach the comprehensive 5 anchor.

4 / 5

Distinctiveness Conflict Risk

Targets a clear, narrow niche (Amazon ARC Region switch) with distinct product-specific triggers and minimal overlap risk with other skills, matching the 5 anchor.
