Claude Skills

Responsive design system with breakpoints, container queries, and fluid typography. Use when implementing responsive layouts, mobile-first design, or adaptive components.

Create and maintain CLAUDE.md files for Claude Code projects. Use when users want to create a new CLAUDE.md, improve an existing one, audit CLAUDE.md quality, set up Claude Code configuration for a repository, or optimize agent context for monorepos. Triggers on requests like "create CLAUDE.md", "improve my CLAUDE.md", "set up Claude Code", "optimize agent context", or "audit my project documentation for Claude".

Automatic internationalization for Swift/SwiftUI apps. Use when writing ANY user-facing text - always localize with String Catalogs, LocalizedStringResource, and proper pluralization patterns.

Look up the latest version of any package using deps.dev API. Use this skill when checking package versions, updating dependencies, adding new packages to a project, or verifying current library versions.

Design AI agents with recommended patterns and architectures

Search the web and extract content using Exa AI. Use when searching for current information, researching topics, fetching content from URLs, or finding code examples. Also use for competitive research, finding similar pages, or extracting structured content.

Invoke a powerful reasoning model for complex analysis tasks. Use when facing difficult bugs, reviewing critical code, designing complex refactors, needing architectural analysis, or seeking consensus on decisions. Also use for 'ask the oracle', 'get a second opinion', 'consult oracle', or 'deep analysis'.

Test SwiftUI apps with XCTest, UI tests, snapshot testing, and async testing. Use when writing unit tests for ViewModels, creating UI automation tests, implementing snapshot tests, or testing async code.

Linter-driven refactoring patterns to reduce complexity and improve code quality. Use when linter fails with complexity issues (cyclomatic, cognitive, maintainability) or when code feels hard to read/maintain. Applies storifying, type extraction, and function extraction patterns.

Implement Swift 6 concurrency with async/await, actors, Sendable, Task, MainActor. Use when handling asynchronous operations, managing shared state safely, fixing data race errors, or migrating to Swift 6 strict concurrency.

CUDA and GPU development with Flox. Use for NVIDIA CUDA setup, GPU computing, deep learning frameworks, cuDNN, and cross-platform GPU/CPU development.

Activates when the user asks about AI prompts, needs prompt templates, wants to search for prompts, or mentions prompts.chat. Use for discovering, retrieving, and improving prompts.

Guides strict Test-Driven Development (TDD) using the Red-Green-Refactor cycle. Ensures no production code is written without a prior failing test. Use this skill when implementing new features, fixing bugs, or refactoring code to ensure high test coverage and design quality. Triggers on phrases like 'TDD', 'write tests first', 'test-driven', 'red-green-refactor', 'watch it fail', 'test first', or 'behavior driven'.

Principles and patterns for writing effective React tests with Jest and React Testing Library. Use during implementation for test structure guidance, choosing test patterns, and deciding testing strategies. Emphasizes testing user behavior, not implementation details.

REPL-friendly data visualization and literate programming for Clojure with Kindly convention

React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.

Use this skill for general PostgreSQL table design. **Trigger when user asks to:** - Design PostgreSQL tables, schemas, or data models when creating new tables and when modifying existing ones. - Choose data types, constraints, or indexes for PostgreSQL - Create user tables, order tables, reference tables, or JSONB schemas - Understand PostgreSQL best practices for normalization, constraints, or indexing - Design update-heavy, upsert-heavy, or OLTP-style tables **Keywords:** PostgreSQL schema, table design, data types, PRIMARY KEY, FOREIGN KEY, indexes, B-tree, GIN, JSONB, constraints, normalization, identity columns, partitioning, row-level security Comprehensive reference covering data types, indexing strategies, constraints, JSONB patterns, partitioning, and PostgreSQL-specific best practices.
