aws-cloudformation-auto-scaling

Provides AWS CloudFormation patterns for Auto Scaling including EC2, ECS, and Lambda. Use when creating Auto Scaling groups, launch configurations, launch templates, scaling policies, lifecycle hooks, and predictive scaling. Covers template structure with Parameters, Outputs, Mappings, Conditions, cross-stack references, and best practices for high availability and cost optimization.

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.

The content is highly actionable with executable templates and commands and a clear step sequence, but it under-uses its bundle files — two of three reference files are unreferenced and large example/reference material stays inlined, limiting progressive disclosure.

Suggestions

Link examples.md and reference.md from the body (e.g., a '## Further examples' / '## Resource reference' section pointing to them) so all bundle files are surfaced and SKILL.md can shed inlined detail.

Move the full 'Complete Auto Scaling Template' example and detailed resource snippets into examples.md/reference.md, keeping only a compact quick-start snippet inline in SKILL.md.

Frame the validation/verification commands as an explicit feedback loop (validate → if errors, fix and re-validate → only then deploy) with named checkpoints to raise workflow clarity.

DimensionReasoningScore

Conciseness

The body is mostly efficient with concrete YAML snippets and minimal re-explanation of known concepts, but at ~430 lines it carries some redundancy between the step-by-step sections and the later 'Complete Auto Scaling Template' example.

4 / 5

Actionability

Fully executable, copy-paste-ready CloudFormation YAML and concrete aws-cli commands cover the common cases (ASG, ALB, target-tracking scaling, lifecycle hooks, outputs) without pseudocode placeholders.

5 / 5

Workflow Clarity

A clear 8-step numbered sequence is present with validation/verification commands (validate-template, change sets, describe-*), but these are presented as a flat command menu rather than an explicit validate→fix→retry feedback loop with named checkpoints.

4 / 5

Progressive Disclosure

Structure is reasonable and the single linked reference (constraints.md) is well-signaled, but examples.md and reference.md bundle files exist yet are not referenced anywhere in the body, and substantial example/reference content is inlined in SKILL.md rather than split out.

Description

88%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, third-person description that pairs a clear statement of capabilities with an explicit 'Use when' trigger list. It is comprehensive and well-targeted, with only minor distinctiveness risk from its broad template-structure coverage.

DimensionReasoningScore

Specificity

The description lists multiple concrete actions — 'Auto Scaling groups, launch configurations, launch templates, scaling policies, lifecycle hooks, and predictive scaling' — plus template-structure constructs, giving comprehensive coverage of the domain.

5 / 5

Completeness

It explicitly answers 'what' (CloudFormation patterns for Auto Scaling incl. EC2/ECS/Lambda) and 'when' with a concrete 'Use when...' clause enumerating trigger phrases.

5 / 5

Trigger Term Quality

Strong natural terms users would say (Auto Scaling groups, launch configurations/templates, scaling policies, lifecycle hooks, CloudFormation), but a few common variations or synonyms are missing, so it sits just below the comprehensive anchor.

4 / 5

Distinctiveness Conflict Risk

The CloudFormation-plus-Auto-Scaling niche is distinct with clear triggers, but the trailing 'Covers template structure with Parameters, Outputs, Mappings, Conditions, cross-stack references' broadens toward a general CloudFormation skill, creating minor overlap risk.
