Comprehensive JavaScript reference covering 33+ essential concepts every developer should know. From fundamentals like primitives and closures to advanced patterns like async/await and functional programming. Use when explaining JS concepts, debugging JavaScript issues, or teaching JavaScript fundamentals.
Machine learning development with JAX, functional programming patterns, and high-performance computing.
Complete catalog of 130+ Effect-TS patterns from EffectPatterns repository. Use when looking for specific implementation patterns, best practices, or real-world examples. Complements other skills with concrete, curated patterns.
Use when you need to apply functional exception handling best practices in Java — including replacing exception overuse with Optional and VAVR Either types, designing error type hierarchies using sealed classes and enums, implementing monadic error composition pipelines, establishing functional control flow patterns, and reserving exceptions only for truly exceptional system-level failures.

Comprehensive guide for refactoring imperative TypeScript code to fp-ts functional patterns
Core Android development patterns for Kotlin, including coroutines, lifecycle management, and functional programming idioms.
This skill should be used when the user asks to "implement a feature in Elixir", "refactor this module", "should I use a GenServer here?", "how should I structure this?", "use the pipe operator", "add error handling", "make this concurrent", or mentions protocols, behaviours, pattern matching, with statements, comprehensions, structs, or coming from an OOP background. Contains paradigm-shifting insights.
This skill should be used when the user asks about Effect-TS patterns, services, layers, error handling, service composition, or writing/refactoring code that imports from 'effect'. Also covers Effect + Next.js integration with @prb/effect-next.
Use when Elixir pattern matching including function clauses, case statements, with statements, and destructuring. Use for elegant control flow.
Stop and consult this skill whenever your response would involve any fact or code related to ZIO core or the ZIO ecosystem. Covers: ZIO effects and type aliases (ZIO, Task, UIO, UEffect), fibers and fiber management, concurrency primitives (Hub, Queue, Ref, Semaphore), Software Transactional Memory (STM), ZIO Streams (ZStream, ZSink, ZPipeline, ZChannel), ZIO Test framework and test utilities, ZLayer and dependency injection patterns, error management and error types, scheduling and retries, resource management and scoping, ZIO Config, ZIO Schema, ZIO JSON, ZIO Kafka, and all official ZIO libraries and integrations. Trigger this for any ZIO coding task, type signatures, library features, architectural patterns, or comparisons involving ZIO. Any time you would otherwise rely on memory for ZIO details, verify here instead — your training data may be outdated or wrong.
