aws-cloudformation-rds

Provides AWS CloudFormation patterns for Amazon RDS databases. Use when creating RDS instances (MySQL, PostgreSQL, Aurora), DB clusters, multi-AZ deployments, parameter groups, subnet groups, and implementing template structure with Parameters, Outputs, Mappings, Conditions, and cross-stack references.

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.

A well-structured, actionable CloudFormation RDS skill: real YAML/CLI examples, a sequenced build workflow with validation, and clean one-level-deep reference splits. The main weakness is redundancy between the per-step snippets and the fully assembled example, plus a few undefined parameter references in the examples.

Suggestions

Remove the duplicated subnet-group, security-group, and instance snippets from the Examples section or replace them with a single assembled template that only adds what the steps did not already show (KMS key, DeletionPolicy, Conditions).

Define every parameter the example templates reference (MasterUserPassword, KmsKeyId, VpcId, SubnetIds) in the shown Parameters block, or note explicitly that they come from an upstream stack.

Interleave a 'Validate before deploy' checkpoint into the Steps 1-6 flow (e.g. after Step 6) rather than only in a separate trailing section, to make the validate-fix-retry loop part of the main workflow.

DimensionReasoningScore

Conciseness

Efficient body of code, tables, and references with no concept padding, but the fully assembled Examples template substantially duplicates the Steps 1-6 snippets (subnet group, security group, instance) and references appear both inline and again in the References section — minor trimming available. Not a 5 because of this redundancy; not a 3 because there is no unnecessary concept explanation.

4 / 5

Actionability

Provides concrete, copy-paste-ready CloudFormation YAML and AWS CLI commands across the common cases, but the Step 4 instance references MasterUserPassword and the Examples template references KmsKeyId/VpcId that are not defined in the shown Parameters — minor gaps keeping it below fully executable. Not a 3 because the shown code is real YAML, not pseudocode.

4 / 5

Workflow Clarity

Steps 1-6 are clearly sequenced and a dedicated Validation Steps section covers validate-template, change-set review, then execute for this destructive infrastructure operation. Below 5 because validation is a separate trailing section rather than explicit per-step checkpoints with a fix-and-retry feedback loop; above 3 because explicit validation commands are present.

4 / 5

Progressive Disclosure

Clear overview body pointing to well-signaled, one-level-deep references (template-structure.md, database-components.md, security-secrets.md, high-availability.md, operational-practices.md, constraints.md, examples.md, reference.md), all verified present in references/, with a grouped References section for easy navigation.

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 ('Provides...') description that names a clear niche and many concrete capabilities with an explicit 'Use when' trigger clause. It hits the top anchor on all four dimensions with no fluff or over-claims.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'creating RDS instances (MySQL, PostgreSQL, Aurora), DB clusters, multi-AZ deployments, parameter groups, subnet groups' plus template sections (Parameters, Outputs, Mappings, Conditions, cross-stack references) — giving comprehensive coverage rather than 1-2 actions.

5 / 5

Completeness

Explicitly answers both what ('Provides AWS CloudFormation patterns for Amazon RDS databases') and when ('Use when creating RDS instances...') with concrete trigger phrases, matching the top anchor exactly.

5 / 5

Trigger Term Quality

Comprehensive natural terms users actually say: 'RDS instances', 'MySQL, PostgreSQL, Aurora', 'DB clusters', 'multi-AZ deployments', 'parameter groups', 'subnet groups' — engine names act as synonyms covering common variations.

5 / 5

Distinctiveness Conflict Risk

Clear niche (CloudFormation for RDS specifically) with distinct triggers; the engine/type qualifiers make overlap with generic CloudFormation or EC2 skills minimal.
