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 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.
Best practices and guidelines for TypeScript (2025-2026 Edition), focusing on TS 5.x+, modern type safety, and performance.
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.
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 TypeScript for type-safe JavaScript: types, interfaces, generics, narrowing, tsconfig, modules, and strict mode. Use when writing or reviewing TypeScript, configuring tsconfig.json, defining types or interfaces, generics, type inference, or when the user mentions TypeScript, TS, or type checking.
Use when forced to use any. Use when any is too broad. Use when function types need any.
TypeScript language expertise for type-safe, production-quality code. Use for advanced type system features (generics, discriminated unions, conditional and mapped types), strict mode configuration, type-safe APIs with zod/trpc/prisma, and modern tooling across Node, Deno, and Bun.
MUST be used whenever fixing correctness and error handling issues in a Flows app. This skill finds AND fixes bugs, missing error states, unhandled rejections, and edge-case failures — it does not just report them. Triggers: correctness, error handling, bug fix, edge case, crash, unhandled, null, undefined, empty state, loading state, error boundary, try catch, async error, useEffect cleanup, type guard, runtime error, robustness.
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.
