Advanced TypeScript patterns for strict mode development. Covers type utilities (Pick, Omit, Partial, Record, Awaited), generics with constraints and inference, type guards and narrowing, discriminated unions, conditional and mapped types, template literal types, const assertions, satisfies operator, module patterns, and modern JavaScript idioms (eslint-plugin-unicorn). Use when building type-safe APIs, preventing runtime errors through types, working with strict TypeScript configuration, debugging complex type errors, or enforcing modern JS idioms. Use for generics, type guards, utility types, strict mode, type inference, narrowing, type safety, const assertions, satisfies, module augmentation, unicorn, for-of, modern-js.
TypeScript wizard specializing in advanced type systems, complex generics, and eliminating any types
TypeScript 5.x development with type system, generics, utility types, and strict mode patterns. Use when writing TypeScript code or adding types to JavaScript projects.
Swift language structures including collections, optionals, closures, generics, control flow, and core language features.
Advanced TypeScript types (generics, conditionals, mapped, utilities). Use when building type-safe libraries or implementing complex type logic.
Java coding standards for Spring Boot services: naming, immutability, Optional usage, streams, exceptions, generics, and project layout.
Python type checking expertise using ty - the extremely fast type checker by Astral. Use when: (1) Adding type annotations to Python code, (2) Fixing type errors reported by ty, (3) Migrating from mypy/pyright to ty, (4) Configuring ty for projects, (5) Understanding advanced type patterns (generics, protocols, intersection types), (6) Setting up ty in editors (VS Code, Cursor, Neovim, PyCharm).
Master enterprise-grade TypeScript development with type-safe patterns, modern tooling, and framework integration. This skill provides comprehensive guidance for TypeScript 5.9+, covering type system fundamentals (generics, mapped types, conditional types, satisfies operator), enterprise patterns (error handling, validation with Zod), React integration for type-safe frontends, NestJS for scalable APIs, and LangChain.js for AI applications. Use when building type-safe applications, migrating JavaScript codebases, configuring modern toolchains (Vite 7, pnpm, ESLint, Vitest), implementing advanced type patterns, or comparing TypeScript with Java/Python approaches.
ArkType runtime validation with TypeScript-native syntax. Type-safe schemas using string expressions, morphs, scopes, and generics. Use when defining schemas, validating data, transforming input, or building type-safe APIs with ArkType.
MUST be used when user asks to document TypeScript or Vue code — add TSDoc/JSDoc blocks, docblocks, или «задокументировать» functions, classes, methods, interfaces, type aliases, enums, generics, Vue composables, defineProps/defineEmits/defineModel. Enforces strict TSDoc spec (tsdoc.org) and writes all descriptions in Russian. Triggers on phrases like «добавь tsdoc», «задокументируй», «напиши док», «add tsdoc», «document this», «generate jsdoc».
TypeScript refactoring and modernization guidelines from a principal specialist perspective. This skill should be used when refactoring, reviewing, or modernizing TypeScript code to ensure type safety, compiler performance, and idiomatic patterns. Triggers on tasks involving TypeScript type architecture, narrowing, generics, error handling, or migration to modern TypeScript features.
Comprehensive naming convention guide for TypeScript and Angular applications. Covers casing rules (camelCase, PascalCase, UPPER_CASE), prefix conventions (I for interfaces, _ for private, T for generics), boolean naming, the S-I-D principle (Short, Intuitive, Descriptive), context duplication, and structured naming patterns (P/HC/LC for variables, A/HC/LC for functions). Use when writing, reviewing, or refactoring TypeScript code. Triggers on tasks involving naming, variables, functions, interfaces, or code style.
