Coding

This skill guides developers through implementing Metal kernels for PyTorch operators on Apple Silicon (MPS). It covers the complete workflow including updating dispatch configuration in native_functions.yaml, writing Metal shader code with type-specialized functors, implementing host-side stubs in Objective-C++, and testing the implementation.

Add unsigned integer (uint) type support to PyTorch operators by updating AT_DISPATCH macros. Use when adding support for uint16, uint32, uint64 types to operators, kernels, or when user mentions enabling unsigned types, barebones unsigned types, or uint support.

Convert PyTorch AT_DISPATCH macros to AT_DISPATCH_V2 format in ATen C++ code. Use when porting AT_DISPATCH_ALL_TYPES_AND*, AT_DISPATCH_FLOATING_TYPES*, or other dispatch macros to the new v2 API. For ATen kernel files, CUDA kernels, and native operator implementations.

A comprehensive TypeScript reference skill that teaches advanced type system concepts including generics, conditional types, mapped types, template literal types, and utility types. It provides code examples and best practices for building type-safe applications without executing any code.

A comprehensive guide to profiling and optimizing Python code. Covers CPU and memory profiling tools (cProfile, memory_profiler, py-spy), optimization patterns like list comprehensions, caching with lru_cache, NumPy vectorization, and parallel processing with multiprocessing and asyncio.

A comprehensive reference guide for modern JavaScript (ES6+) features and patterns. Covers arrow functions, destructuring, async/await, Promises, functional programming, classes, modules, iterators, generators, and performance optimization techniques for writing clean, maintainable code.

This skill teaches systematic debugging techniques using the scientific method approach. It covers debugging tools and techniques for JavaScript/TypeScript, Python, and Go, including profiler usage, memory leak detection, binary search debugging with git bisect, and best practices for tracking down elusive bugs in any codebase.

A comprehensive documentation resource for writing production-grade Bash scripts. It covers defensive programming techniques, POSIX compliance, Bats testing patterns, and ShellCheck configuration for static analysis and code quality.

A comprehensive educational skill for systems programming. It provides production-ready patterns for Go concurrency (goroutines, channels, worker pools), Rust async programming (Tokio, streams, error handling), and memory safety across C, C++, and Rust. Includes specialized agents for each language to assist with development tasks.

A comprehensive game development reference skill covering multiple engines and platforms. Provides production-ready patterns for Godot 4 GDScript (signals, state machines, object pooling), Unity ECS/DOTS (high-performance entity systems, Jobs, Burst), Unity general development (rendering pipelines, cross-platform deployment), and Minecraft Bukkit/Spigot/Paper plugin development.

A comprehensive migration toolkit that helps upgrade legacy applications to modern frameworks. Covers AngularJS to Angular migration with hybrid mode support, React class-to-hooks conversion, database schema migrations across ORMs (Sequelize, TypeORM, Prisma), and major dependency version upgrades with compatibility analysis and rollback procedures.

Pre-implementation confidence assessment (≥90% required). Use before starting any implementation to verify readiness with duplicate check, architecture compliance, official docs verification, OSS references, and root cause identification.

Use when you have a spec or requirements for a multi-step task, before touching code

Use when executing implementation plans with independent tasks in the current session

Use when completing tasks, implementing major features, or before merging to verify work meets requirements

Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation

Use when you have a written implementation plan to execute in a separate session with review checkpoints

Provides comprehensive guidance for Stripe payment integrations, recommending modern APIs like CheckoutSessions and Payment Element while warning against deprecated patterns. The skill references official Stripe documentation for checkout flows, subscriptions, Connect platforms, and webhook handling.

Comprehensive toolkit for developing Claude Code plugins with 7 specialized skills covering hooks, MCP integration, plugin structure, settings, commands, agents, and skill development. Includes validation utilities, working examples, and detailed documentation following progressive disclosure principles.

This plugin transforms Claude into an interactive learning assistant that asks you to write meaningful code at key decision points (5-10 lines) instead of implementing everything automatically. It also provides educational insights about implementation choices and codebase patterns, helping you learn by doing rather than just watching.

Feature Development provides a structured 7-phase workflow for building new features: discover requirements, explore the codebase with specialized agents, clarify ambiguities, design architecture, implement with approval, review quality, and summarize results. Uses code-explorer, code-architect, and code-reviewer agents in parallel for thorough analysis.

This skill provides installation instructions for the Lua Language Server (lua-language-server), which enables code intelligence, diagnostics, and language server features for .lua files in Claude Code. Users must install the language server binary separately via Homebrew, snap, pacman, or manual download.
