TypeScript expert for type system, generics, utility types, and strict mode patterns
Use when working with TypeScript's type system including strict mode, advanced types, generics, type guards, and compiler configuration.
Use when deciding whether to use Go generics, writing generic functions or types, choosing constraints, or picking between type aliases and type definitions. Also use when a user is writing a utility function that could work with multiple types, even if they don't mention generics explicitly. Does not cover interface design without generics (see go-interfaces).
Custom React hook best practices — dependency arrays, cleanup, stale closures, TypeScript generics, composition, and extraction heuristics
Generate and review Java code using patterns and best practices from Joshua Bloch's "Effective Java" (3rd Edition). Use this skill whenever the user asks about Java best practices, API design, object creation patterns, generics, enums, lambdas, streams, concurrency, serialization, method design, exception handling, or writing clean, maintainable Java code. Trigger on phrases like "Effective Java", "Java best practices", "builder pattern", "static factory", "defensive copy", "immutable class", "enum type", "generics", "bounded wildcard", "PECS", "stream pipeline", "optional", "thread safety", "serialization proxy", "checked exception", "try-with-resources", "composition over inheritance", "method reference", "functional interface", or "Java API design."
Use when you need to review, improve, or refactor Java code for generics quality — including avoiding raw types, applying the PECS (Producer Extends Consumer Super) principle for wildcards, using bounded type parameters, designing effective generic methods, leveraging the diamond operator, understanding type erasure implications, handling generic inheritance correctly, preventing heap pollution with @SafeVarargs, and integrating generics with modern Java features like Records, sealed types, and pattern matching.

Use for Luau type-system work focused on strictness modes, annotations, inference-aware API design, generics, refinements, advanced type patterns, and Roblox-aware type usage at the type level.
Use skill if you are writing or reviewing framework-agnostic TypeScript and need strict typing, tsconfig/lint decisions, safer refactors, or guidance on generics, unions, and typed boundaries.
Intelligent Retrieval Assistant for Cangjie Language Documentation. Supports 4 search modes (Direct Search, PageIndex Intelligent Retrieval, Hybrid Mode, Exploratory Learning). It is used when users need to: (1) Query Cangjie syntax (variable declaration, function definition, generics, etc.), (2) Look up standard library APIs (String, Array, HashMap, etc.), (3) Learn about Cangjie features or get started with the language, (4) Conduct any documentation queries related to Cangjie/cangjie/cj. It uses four MCP tools: cangjie_docs_overview, cangjie_list_docs, cangjie_search, and cangjie_get_doc for intelligent retrieval.
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.
Advanced Rust patterns for ownership, traits, async, error handling, macros, type system tricks, unsafe, and performance. Use when tackling complex Rust problems — not basic syntax, but multi-concern tasks like designing cancellation-safe async services, choosing between trait objects and generics, building typestated APIs, structuring error hierarchies across crate boundaries, writing proc macros, or optimizing hot paths with zero-cost abstractions. Do not use for basic Rust syntax, simple CLI tools, or beginner ownership questions.
Search for and add electronic components to a Zener PCB project using LCSC + easyeda2kicad. Use when designing a board, module, or subsystem and you need a part package that is not already in the workspace or covered by stdlib generics. Covers MPN → LCSC C-number lookup, `easyeda2kicad` import, and generation of a Zener component wrapper (.zen) from the imported `.kicad_sym`.
