data-model-reviewer

TypeScript data model analysis scans your type files to detect duplicate interface and type definitions, identifies single sources of truth violations, and flags redundant declarations across your project. Run the Skill on targeted type directories or your entire repository to get a refactor plan with concrete consolidation steps.

Enforce type safety by scanning interfaces for unsafe patterns like `any`, promoting literal unions and enums over magic strings, and validating optional properties. The Skill evaluates your models against type-safety rules and outputs a checklist-based review with specific improvements for each interface.

Validate ID patterns and nesting depth by analyzing type relationships across your project. The Skill ensures ID types remain consistent throughout related interfaces and detects excessive nesting that complicates your data model, then reports violations with refactor recommendations.

You can target specific type files using glob patterns like `**/types/**/*.ts` and `**/*.d.ts` or analyze your entire repository. The Skill accepts both scoped and project-wide analysis, letting you focus on particular domains or run a comprehensive type audit across all declarations.

The review produces results in an examples.md format checklist that lists duplication issues, type-safety violations, ID inconsistencies, and nesting problems with concrete refactor suggestions. Each finding includes the affected types and the specific improvement needed.

No external dependencies are required. The Skill uses file reading and grep-based search to analyze your TypeScript types directly. Point it at your type file locations and it scans immediately to generate the safety and duplication review.
