aws-cloudformation-dynamodb

Provides AWS CloudFormation patterns for DynamoDB tables, GSIs, LSIs, auto-scaling, and streams. Use when creating DynamoDB tables with CloudFormation, configuring primary keys, local/global secondary indexes, capacity modes (on-demand/provisioned), point-in-time recovery, encryption, TTL, and implementing template structure with Parameters, Outputs, Mappings, Conditions, cross-stack references.

Quality

Content

70%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 delivers executable examples, a validated deploy workflow with rollback feedback, and a useful constraints/troubleshooting reference. It is held back by frontmatter-duplicating overview sections and two bundle files (examples.md, reference.md) that are present but never referenced from the skill body.

Suggestions

Remove or collapse the Overview and When-to-Use sections (lines 11-18) since they duplicate the frontmatter description verbatim, or replace them with information not already in the description.

Add explicit links to references/examples.md and references/reference.md from the body (e.g., in the References or Quick Reference section) so all bundle files are discoverable, or remove them if unused.

Complete the auto-scaling example by defining the AutoScalingRole (and showing the ScalingPolicy) so the snippet is self-contained and copy-pasteable.

DimensionReasoningScore

Conciseness

The body is mostly efficient, but the Overview and When-to-Use sections (lines 11-18) restate the frontmatter description almost verbatim, adding tokens without new information; not 4 because this duplication is more than a minor trim, and not 2 because the technical sections (examples, quick reference, constraints) are lean and earn their place.

3 / 5

Actionability

Provides concrete, copy-pasteable CloudFormation YAML and explicit AWS CLI commands ('aws cloudformation validate-template', 'create-stack', 'describe-stack-events'); not 5 because the auto-scaling example references an undefined AutoScalingRole and DynamoDBTable resource, leaving a minor gap in that snippet.

4 / 5

Workflow Clarity

The 12-step Instructions sequence includes an explicit validation checkpoint (step 9: validate-template before deploy) and a feedback loop (step 11 monitor events for ROLLBACK, step 12 on failure review events, fix, re-deploy), matching the anchor for clear sequence with validation and error recovery; the destructive-operation cap does not apply because validation is present.

5 / 5

Progressive Disclosure

Structure is decent and the two linked references (complete-examples.md, advanced-configuration.md) are clearly signaled one level deep, but the references/ bundle also contains examples.md and reference.md that are never linked from the body, so half the bundle is not navigable; not 4 because orphaned bundle files are more than a minor organization gap.

Description

100%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 concretely states capabilities and provides an explicit 'Use when' clause with comprehensive trigger keywords and synonyms. It clearly distinguishes this skill from neighboring AWS skills.

DimensionReasoningScore

Specificity

Lists many concrete actions ('creating DynamoDB tables', 'configuring primary keys', 'local/global secondary indexes', 'capacity modes (on-demand/provisioned)', 'point-in-time recovery, encryption, TTL', 'Parameters, Outputs, Mappings, Conditions, cross-stack references'), matching the comprehensive-coverage anchor; not below because nothing major is missing.

5 / 5

Completeness

Explicitly answers both what ('Provides AWS CloudFormation patterns for DynamoDB tables, GSIs, LSIs, auto-scaling, and streams') and when ('Use when creating DynamoDB tables with CloudFormation, configuring primary keys...') with concrete trigger phrases, matching the top anchor exactly.

5 / 5

Trigger Term Quality

Covers the natural terms users say for this domain ('DynamoDB tables', 'CloudFormation', 'GSIs', 'LSIs', 'auto-scaling', 'TTL') with synonyms expanded ('local/global secondary indexes', 'on-demand/provisioned'); not 4 because synonym coverage is comprehensive rather than missing a few.

5 / 5

Distinctiveness Conflict Risk

Targets a clear niche (CloudFormation-managed DynamoDB tables/indexes) with distinct triggers unlikely to fire for unrelated skills; not 4 because the DynamoDB-plus-CloudFormation scoping leaves only minimal overlap risk.
