Quick Review

Excellent database schema design skill with comprehensive coverage of SQL/NoSQL design principles, normalization, indexing, constraints, and migrations. The Description clearly conveys capabilities enabling straightforward invocation. Task knowledge is thorough with concrete examples, anti-patterns, checklists, and deep-dive sections covering normalization forms, data types, indexing strategies, and zero-downtime migrations. Structure is well-organized with a logical flow from quick start to commands to principles to detailed expandable sections, though SKILL.md is quite lengthy. Novelty is solid—designing production-ready schemas with normalization, indexing strategies, constraint design, and migration patterns would require significant tokens and domain expertise from a CLI agent alone. Minor improvements could include moving some deep-dive content to separate reference files for even cleaner structure, and adding more NoSQL-specific patterns beyond MongoDB basics.
