單元測試

Generate Vitest test files for the dealflow-network project with proper setup, teardown, database patterns, and assertion styles. Use when creating tests for new features, database operations, or API endpoints.

Implements testing strategies for React Native components, MST stores, and services using Jest, React Testing Library, and Maestro. Use when writing unit, integration, or E2E tests in Fitness Tracker App.

Эксперт k6 нагрузочного тестирования. Используй для performance testing, load scenarios и stress tests.

Challenge and stress-test ideas through adversarial thinking. Use when user wants to "poke holes", "challenge this", "what could go wrong", "devil's advocate", "stress test", "red team", "pre-mortem", "review this", "validate", "audit", or needs to find weaknesses before they become problems. (project)

Implements modern JavaScript features from ES2020-ES2024 including optional chaining, nullish coalescing, private fields, Promise methods, and array transformations. Use when modernizing JavaScript code, using ES2024 features, or when user asks about latest ECMAScript standards.

Performs comprehensive frontend quality assurance reviews using browser automation. Systematically tests UI elements, discovers and reports bugs to GitHub Issues, and provides improvement recommendations. Uses Chrome DevTools Skill for interactive testing. This skill should be used when performing quality assurance reviews of frontend UI components, testing user interfaces for bugs or usability issues, validating frontend implementations before deployment, or conducting systematic UI testing across multiple components.

Generate comprehensive tests following three-layer pyramid - unit (Vitest), integration (real database), E2E (Playwright). Use when user needs "add tests", "improve coverage", "test [feature]", "write E2E tests", "generate test factory", or mentions testing auth, forms, database, AI features, visualizations, real-time collaboration, performance, accessibility, or import/export. Provides templates and patterns for 80%+ coverage including AI mocking, chart testing, WebSocket testing, and Page Object Models. Do NOT use when building new features (use worldcrafter-feature-builder which includes tests), database-only changes (use worldcrafter-database-setup), or simple routes (use worldcrafter-route-creator).

Add backend integration testing with Vitest to an existing app. Sets up isolated test database schema and writes tests for tRPC routers.

Validate API contracts and ensure compatibility. Use when checking OpenAPI specs, running contract tests, detecting breaking changes, or generating types from API specifications.

Comprehensive statistical analysis toolkit for research. Conduct hypothesis tests (t-test, ANOVA, chi-square), regression, correlation, Bayesian stats, power analysis, assumption checks, and APA reporting. Use when the user asks about statistics, needs help analyzing data, or when writing methods sections that include statistical approaches.

Hidden quality gate that runs before showing "Done!" to user - ensures all tests pass, build succeeds, and requirements met before claiming completion

Create best-in-class repository scaffolds with modern tooling, security, CI/CD, testing, and documentation. Works for code, data science, ontologies, APIs, and CLI projects.

Generates .stylelintrc configuration for linting CSS, SCSS, and Vue component styles. Auto-detects stylesheet type and fetches latest package versions for plugins.

Build execution philosophy including TDD discipline, Minimal Intervention Principle, system awareness, and verification protocols. Use when implementing code, managing build phase, enforcing test-first practices, or preventing accumulative complexity. Triggers on: build phase, TDD, test first, red green refactor, minimal code, system awareness, implementation, code quality, verification protocols, build philosophy.

Use this skill when writing Go code following the Uber Go Style Guide. Provides comprehensive guidance on idiomatic Go patterns, error handling, concurrency safety, performance optimization, and test-driven development. Covers all critical Uber Go rules including channel sizing, goroutine management, interface design, and proper error handling. Appropriate for any task involving .go files, Go code reviews, refactoring, or implementing Go best practices.

Safe code refactoring with DDD patterns and test preservation

Production-tested setup for Zustand state management in React applications with TypeScript. This skill provides comprehensive patterns for building scalable, type-safe global state. Use when: setting up global state in React, migrating from Redux or Context API, implementing state persistence with localStorage, configuring TypeScript with Zustand, using slices pattern for modular stores, adding devtools middleware for debugging, handling Next.js SSR hydration, or encountering hydration errors, TypeScript inference issues, or persist middleware problems. Prevents 5 documented issues: Next.js hydration mismatches, TypeScript double parentheses syntax errors, persist middleware export errors, infinite render loops, and slices pattern type inference failures. Keywords: zustand, state management, React state, TypeScript state, persist middleware, devtools, slices pattern, global state, React hooks, create store, useBoundStore, StateCreator, hydration error, text content mismatch, infinite render, localStorage, sessionStorage, immer middleware, shallow equality, selector pattern, zustand v5
