87%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A concise, highly actionable reference skill with excellent progressive disclosure and concrete DynamoDB design conventions. The only gap is the absence of explicit validation/feedback-loop workflows for its database operations, which caps workflow clarity.
Suggestions
Add an explicit design workflow with sequenced steps (e.g., list access patterns → choose keys → select indexes → verify with sample queries) so the process is unambiguous.
For concurrency and write operations, include a brief validate/retry checkpoint (e.g., use ConditionExpression with optimistic locking and retry on ConditionalCheckFailedException) to provide the feedback loop the rubric expects for database ops.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Lean, opinionated body using tables and code blocks; it assumes Claude's competence and avoids explaining what DynamoDB is, so nearly every token earns its place. | 3 / 3 |
Actionability | Provides concrete PK/SK encoding examples, a worked one-to-many item layout, explicit GSI-vs-LSI conditions, and specific capacity figures (400 KB limit, '~100 KB → S3 offload', '2x WCU'), giving copy-ready design guidance. | 3 / 3 |
Workflow Clarity | Well-structured with a corrective Common-Mistakes table, but there is no explicit sequenced workflow, and the database/concurrency operations lack validate/retry feedback loops — which the rubric notes cap workflow clarity at 2 for database operations. | 2 / 3 |
Progressive Disclosure | Clear overview in SKILL.md with five well-signaled one-level-deep references (all verified to exist in references/) and a consolidated Reference Files section, splitting detail appropriately. | 3 / 3 |
