clean-architecture
42 Clean Architecture rules organized by priority for designing maintainable, testable software systems.
- Covers 8 rule categories from dependency direction and entity design (critical) through testing architecture (low-medium), each with specific guidance and code examples
- Dependency rules enforce inward-pointing dependencies, interface ownership, and acyclic component graphs to prevent architectural decay
- Entity and use case rules isolate business logic from frameworks, persistence, and presentation concerns through clear boundaries and explicit ports
- Includes practical patterns like humble objects, anti-corruption layers, and partial boundaries for phased architectural improvements
Clean Architecture Best Practices
Comprehensive guide to Clean Architecture principles for designing maintainable, testable software systems. Based on Robert C. Martin's "Clean Architecture: A Craftsman's Guide to Software Structure and Design." Contains 42 rules across 8 categories, prioritized by architectural impact.
When to Apply
Reference these guidelines when:
- Designing new software systems or modules
- Structuring dependencies between layers
- Defining boundaries between business logic and infrastructure
- Reviewing code for architectural violations
- Refactoring coupled systems toward cleaner structure
Rule Categories by Priority
| Priority | Category | Impact | Prefix |
|---|---|---|---|
| 1 | Dependency Direction | CRITICAL | dep- |
| 2 | Entity Design | CRITICAL | entity- |

zod
Zod schema validation best practices for type safety, parsing, and error handling. This skill should be used when defining z.object schemas, using z.string validations, safeParse, or z.infer. This skill does NOT cover React Hook Form integration patterns (use react-hook-form skill) or OpenAPI client generation (use orval skill).
2.4Kemilkowal-animations
Emil Kowalski's animation best practices for web interfaces. Use when writing, reviewing, or implementing animations in React, CSS, or Framer Motion. Triggers on tasks involving transitions, easing, gestures, toasts, drawers, or motion.
967vitest
Vitest testing framework patterns for test setup, async testing, mocking with vi.*, snapshots, and test performance (formerly test-vitest). This skill should be used when writing or debugging Vitest tests. This skill does NOT cover TDD methodology (use test-tdd skill), API mocking with MSW (use test-msw skill), or Jest-specific APIs.
930react-hook-form
React Hook Form performance optimization for client-side form validation using useForm, useWatch, useController, and useFieldArray. This skill should be used when building client-side controlled forms with React Hook Form library. This skill does NOT cover React 19 Server Actions, useActionState, or server-side form handling (use react-19 skill for those).
885typescript
This skill should be used when the user asks to "optimize TypeScript performance", "speed up tsc compilation", "configure tsconfig.json", "fix type errors", "improve async patterns", or encounters TS errors (TS2322, TS2339, "is not assignable to"). Also triggers on .ts, .tsx, .d.ts file work involving type definitions, module organization, or memory management. Does NOT cover TypeScript basics, framework-specific patterns, or testing.
850nuqs
nuqs (type-safe URL query state) best practices for Next.js and other React frameworks. This skill should be used when writing, reviewing, or refactoring code that uses nuqs for URL state management. Triggers on tasks involving useQueryState, useQueryStates, search params, URL state, query parameters, nuqs parsers, limitUrlUpdates, Standard Schema, NuqsAdapter, or Next.js routing with state.
