Expert code review for TypeScript/Node.js applications focusing on quality and best practices
TypeScript performance optimization guidelines for build times, type-checking, declaration emit, and editor responsiveness. This skill should be used when writing, reviewing, or optimizing TypeScript code and tsconfig settings. Triggers on tasks involving slow builds, slow type-checking, CI timeouts, editor lag, tsserver memory issues, monorepo configuration, project references, incremental builds, declaration emit, or any TypeScript performance investigation.
Precision and type-safety hardening for Phoenix calculation paths. Use when configuring ESLint/TypeScript, replacing parseFloat in P0 files, or validating Decimal.js precision.
Chrome拡張機能開発に関する包括的なガイド。ベストプラクティス、アンチパターンの回避、型安全性、Manifest V3への準拠をサポート。Claudeが以下のためにChrome拡張機能を扱う場合に使用:(1) 新規拡張機能の計画・作成、(2) 既存コードのデバッグ・修正、(3) セキュリティレビュー、(4) Manifest V2からV3への移行、(5) TypeScript型の問題解決。
Implement, refactor, or review worker-based multithreading in TypeScript/JavaScript apps (browser or Node). Use when offloading CPU-heavy loops to Web Workers, setting up a worker pool, moving data across threads, or diagnosing worker crashes, slowdowns, or synchronization bugs.
MCP ツールを TypeScript コードとして実行し、トークン消費を最大 98.7% 削減します。Serena MCP ツール呼び出しが必要な場合、大規模データセット処理、コードベース全体への操作、バッチ処理、プライバシーに配慮したデータ処理が必要な場合に使用してください。
Эксперт по TypeScript. Используй для типизации, дженериков, декораторов, паттернов проектирования и best practices в TypeScript.
Teaches how to write custom type guards with type predicates and use built-in type narrowing in TypeScript. Use when working with unknown types, union types, validating external data, or implementing type-safe runtime checks.
TypeScript performance optimization guidelines for build times, type-checking, declaration emit, and editor responsiveness. This skill should be used when writing, reviewing, or optimizing TypeScript code and tsconfig settings. Triggers on tasks involving slow builds, slow type-checking, CI timeouts, editor lag, tsserver memory issues, monorepo configuration, project references, incremental builds, declaration emit, isolatedDeclarations, --noCheck flag, TypeScript 5.6+ features, TypeScript 7 migration, or any TypeScript performance investigation.
Implement, refactor, or review worker-based multithreading in TypeScript/JavaScript apps (browser or Node). Use when offloading CPU-heavy loops to Web Workers, setting up a worker pool, moving data across threads, or diagnosing worker crashes, slowdowns, or synchronization bugs.
Analyze TypeScript errors and provide detailed diagnostics with root cause analysis and specific fix recommendations
Teaches when type assertions are safe versus dangerous in TypeScript. Use when considering using 'as' keyword, type casting, or when working with external data that might use assertions instead of proper validation.
TypeScript strict patterns and best practices. Trigger: When implementing or refactoring TypeScript in .ts/.tsx (types, interfaces, generics, const maps, type guards, removing any, tightening unknown).
East programming language - a statically typed, expression-based language embedded in TypeScript. Use when writing East programs with @elaraai/east. Triggers for: (1) Writing East functions with East.function() or East.asyncFunction(), (2) Defining types (IntegerType, StringType, ArrayType, StructType, VariantType, etc.), (3) Using platform functions with East.platform() or East.asyncPlatform(), (4) Compiling East programs with East.compile(), (5) Working with East expressions (arithmetic, collections, control flow), (6) Serializing East IR with .toIR() and EastIR.fromJSON(), (7) Standard library operations (formatting, rounding, generation).
TypeScript coding conventions and best practices. Use when working with TypeScript files, defining types, or setting up TypeScript projects.
TypeScript development best practices, patterns, and conventions. Use when writing TypeScript code, reviewing .ts/.tsx files, discussing type safety, generics, utility types, or TypeScript project configuration. Triggers on mentions of TypeScript, tsconfig, type inference, generics, discriminated unions, React TypeScript.
TypeScript type system for type-safe JavaScript development. Covers types, interfaces, generics, and configuration for both frontend and backend. Trigger: When writing TypeScript code, when defining types or interfaces, when using generics, when configuring tsconfig.json.
TypeScript development guidelines and patterns. Use this skill when writing TypeScript code, creating React components with TypeScript, configuring tsconfig.json, using advanced types like generics or utility types, or when the user asks about TypeScript best practices.
Adds static typing to JavaScript with TypeScript including type annotations, interfaces, generics, and advanced type utilities. Use when setting up TypeScript projects, defining types, creating generic utilities, or debugging type errors.
