Guides TypeScript best practices for type safety, code organization, and maintainability. Use this skill when configuring TypeScript projects, deciding on typing strategies, writing async code, or reviewing TypeScript code quality.
TypeScript strict mode configuration for 2025. Recommended tsconfig.json settings, strict flags explained, moduleResolution strategies (Bundler vs NodeNext), verbatimModuleSyntax, noUncheckedIndexedAccess. Use when setting up TypeScript projects or migrating to stricter type safety.
Architectural refactoring guide for Rust applications covering type safety, ownership patterns, error handling strategies, API design, project organization, module structure, naming conventions, conversion traits, and idiomatic patterns. Use when refactoring Rust codebases, reviewing PRs for architectural issues, improving type safety, designing error handling strategies, or organizing project structure. Complements the rust-optimise skill (performance patterns). Does NOT cover performance optimization, memory allocation, or async concurrency tuning (see rust-optimise skill).
Use when upgrading to PHP 8.1+, implementing type safety, configuring PHPStan/Rector/PHP-CS-Fixer, or modernizing PHP code with enums, DTOs, and readonly properties.
Core TypeScript conventions for type safety, inference, and clean code. Use when writing TypeScript, reviewing TypeScript code, creating interfaces/types, or when the user asks about TypeScript patterns, conventions, or best practices.
Use when forced to use any. Use when any is too broad. Use when function types need any.
Use when writing, fixing, or editing TypeScript code that touches APIs, JSON, environment variables, storage, databases, browser APIs, SDKs, generated clients, or other external boundaries.
Acts as a Senior Staff Engineer to enforce high-quality software development standards. Use this skill when the user asks for code implementation, architectural review, debugging, or technical design. It ensures all code is production-ready, typed, and architecturally sound.
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.
TypeScript best practices, type safety, and toolchain standards. Use when: - Writing or reviewing TypeScript code - Setting up TypeScript projects or tsconfig - Choosing state management patterns - Configuring build tools (tsup, Vitest) - Avoiding type gymnastics or any-abuse Keywords: TypeScript, tsconfig, strict mode, no-any, pnpm, Vitest, tsup, TanStack Query, discriminated unions, type safety, ESLint
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.
Implement branded (nominal/opaque) types in TypeScript to prevent accidental mixing of structurally identical types. Use when writing type-safe IDs (UserId, PostId), validated strings (Email, URL), unit-specific numbers (Meters, Seconds), or any scenario requiring nominal typing in TypeScript's structural type system.
