Conciseness

The body is lean and assumes competence ('follow the procedure exactly'), but has trimmable duplication: the Overview and 'It uses AWS Secrets Manager... includes proper status monitoring' paragraph restate the frontmatter description, and the Troubleshooting section repeats content that also appears verbatim in the reference file. Not 5 because of this redundancy; not 3 because there is no padding or explanation of concepts Claude already knows.

Actionability

The body itself contains no commands or code — it is a pointer ('follow the procedure exactly. See [Aurora cluster creation procedure]') plus a high-level summary ('creates an empty Aurora cluster first, then adds a database instance'). The referenced file does contain fully executable aws-cli commands, but evaluated on the body alone the concrete guidance is incomplete. Not 4 because no executable detail appears inline; not 2 because the pointer is explicit and the summary accurately conveys the workflow shape and where to execute it.

Workflow Clarity

The body states the sequence clearly ('creates an empty Aurora cluster first, then adds a database instance to make it queryable') and notes 'proper status monitoring with retry logic', delegating to a procedure that contains explicit validation and abort checkpoints (steps 4, 6, 8 with 20-minute failure timeouts). Not 5 because the checkpoints themselves are only summarized, not surfaced even briefly in the body; not 3 because the ordering rationale and the existence of monitoring/retry and validation steps are explicitly stated.

Progressive Disclosure

A clean overview structure with one clearly signaled, one-level-deep reference: 'See [Aurora cluster creation procedure](references/create-amazon-aurora-db-cluster-with-instances.md)' resolves to a real file that itself contains no further references. Content is appropriately split — overview, procedure pointer, and troubleshooting in the body; full SOP detail in the reference. Not 4 because there are no organization gaps: navigation is unambiguous and nothing that belongs in a separate file is inlined.

Specificity

Lists several concrete actions — 'cluster creation, instance provisioning, and Secrets Manager password management in the proper sequence' — plus engine support ('Aurora MySQL or PostgreSQL'). Not 5 because it stops at three actions and omits others the skill actually covers (status monitoring, connection endpoints); not 3 because the actions named are specific and domain-scoped rather than generic.

Completeness

Explicitly answers both: what ('Creates a complete Amazon Aurora database cluster with instances, handling cluster creation, instance provisioning, and Secrets Manager password management') and when ('Use when setting up new Aurora MySQL or PostgreSQL clusters with production-ready configuration') with concrete trigger phrasing. Not 4 because the 'when' clause is specific about engines and use case rather than merely explicit.

Trigger Term Quality

Includes natural terms users would say: 'setting up new Aurora MySQL or PostgreSQL clusters', 'production-ready configuration'. Not 5 because common synonyms and adjacent terms are missing (e.g., 'RDS', 'database instance', 'create a database', 'Aurora DB'); not 3 because the engine names and 'cluster' phrasing cover the primary ways users would express this need.

Distinctiveness Conflict Risk

Aurora cluster creation with managed passwords is a clear niche with engine-specific triggers ('Aurora MySQL or PostgreSQL'). Not 5 because it could overlap with broader RDS/database-setup or Secrets Manager skills; not 3 because the Aurora + engine qualifiers keep it well-distinguishable from generic database skills.
