Lists multiple specific concrete actions and concepts: 'table design, single-table design, GSIs, multi-attribute composite keys, one-to-many relationships, cost optimization, Terraform DynamoDB resources' - these are all concrete, actionable domains.

Clearly answers both what ('Patterns and best practices for Amazon DynamoDB data modeling and access patterns') and when ('Use when the user asks about...') with explicit trigger guidance and a dedicated triggers list.

Excellent coverage of natural terms users would say, including both technical terms (GSI, partition key, sort key, TTL) and conceptual terms (single-table design, access patterns, composite keys). The explicit 'Triggers on:' list provides comprehensive keyword coverage.

Highly distinctive with DynamoDB-specific terminology (GSI, partition key, sort key, single-table design) that would not conflict with other database or general data skills. The niche is clearly defined.

Content is lean and efficient with no unnecessary explanations. Uses tables for quick scanning, avoids explaining what DynamoDB is, and every section provides actionable guidance without padding.

Provides concrete, copy-paste ready MCP server configurations for both macOS/Linux and Windows. Decision frameworks give specific criteria for choosing approaches. Anti-patterns are explicit and actionable.

The skill is primarily a reference/decision guide rather than a multi-step workflow, but the MCP server installation section lacks validation steps (e.g., how to verify the server is working, what to do if connection fails).

Excellent structure with a quick reference table pointing to the detailed reference file, clear section organization, and appropriate content split. The 395-line reference file is properly signaled as the deep-dive resource.
