This guide serves as a comprehensive reference for source-file migration patterns required when upgrading to React 19. It details critical API changes, such as updating `ReactDOM.render` to `createRoot().render()`, modernizing ref handling, and adjusting legacy context usage. It is essential for developers migrating large, existing React applications to ensure compatibility with the latest React standards.

Guides React 19 test migrations by outlining act import changes, Simulate-to-fireEvent replacements, full react-dom/test-utils cleanup, and StrictMode call-count verification strategies.

This skill provides comprehensive guidelines and techniques for safe code refactoring. It focuses on improving code structure, readability, and maintainability without altering the external behavior or functionality of the system. Learn to address common code smells, such as long methods, duplicated logic, god objects, and primitive obsession, using established design patterns and best practices. It emphasizes that refactoring should be gradual, test-driven, and methodical.

A comprehensive template for planning large-scale, multi-file refactoring tasks. It enforces a systematic approach by requiring developers to map out the current state, target state, affected files, and execution phases (Types, Implementation, Tests). Crucially, it mandates detailed verification and a robust rollback plan to ensure code stability during major changes.

Roundup gathers GitHub, calendar, email, and chat data from your configured sources and synthesizes it into status briefings that match your tone, audience, and requested timeframe.

Installs npm packages inside virtiofs-mounted Docker workspaces by copying package files to a container-local ext4 directory, running npm ci there, and symlinking node_modules back so native binaries avoid virtiofs crashes.

Clinically informed Claude skill that blends psychology frameworks (IFS, DBT, CFT, schema therapy) with eight wisdom traditions to provide a structured conversation partner for exploring emotions, internal conflicts, and existential distress.

Generates a complete, compilable xUnit integration test project structure for validating complex database migrations, specifically from Oracle to PostgreSQL, within .NET solutions. This scaffolding includes a transaction-rollback base class and a seed data manager, ensuring a robust environment for writing migration integration tests without requiring test cases. Ideal for setting up testing infrastructure before migration validation.

Guides agents to attach to existing Chrome instances via CDP, scan local ports, or expose a fixed endpoint for sharing when explicit remote debugging is requested, while highlighting privacy precautions and workspace limits.

Reads and summarizes local text-based files such as Markdown, JSON, CSV, and source code, including quick type checks and smart tailing for big logs while skipping PDFs, images, and binaries.

A comprehensive automation toolkit for managing Sentry error tracking and monitoring operations. Users can programmatically investigate issues, configure project-level alert rules, manage release versions, and monitor organizational structure. Essential for DevOps and development teams needing deep integration and programmatic control over error data.

This tool provides comprehensive auditing, validation, and generation services for Hreflang tags, crucial for multilingual and multi-regional websites. It checks for common SEO mistakes, including missing self-referencing tags, broken return tags, invalid language/region codes (ISO standards), and canonical URL mismatches. It supports implementation across HTML, HTTP headers, and XML sitemaps, ensuring search engines correctly index all language versions.
