This skill provides a comprehensive guide for implementing robust testing strategies in Python. It covers essential practices such as unit testing, integration testing, mocking external dependencies, and adopting Test-Driven Development (TDD). Use this when writing complex Python test suites, setting up CI/CD testing infrastructure, or mastering advanced techniques like property-based testing and async code verification.

A specialist skill for building robust, scalable, and high-performance React applications. Expertise covers modern patterns including React 19, Server Components (RSC), Next.js App Router, and advanced state management (Redux/Zustand). Ideal for implementing complex features, optimizing rendering, and adhering to strict TypeScript/accessibility standards.

This skill guides the process of modernizing React applications. It covers crucial tasks such as major version upgrades, migrating from class components to functional components using hooks, adopting advanced concurrent features (like Suspense), and utilizing codemods for automated, large-scale code transformation. Ideal for maintaining and scaling complex React codebases.

This skill provides production-ready architectural patterns for developing mobile applications using React Native and Expo. It covers complex topics including state management, advanced navigation patterns, integrating native modules, and implementing robust offline-first functionalities. Ideal for starting new projects or optimizing existing mobile codebases to ensure scalable and performant results.

Auto-activating API Integration skill that guides response transformer work, covering common patterns, third-party APIs, webhooks, SDK generation, and delivers best-practice code plus validation advice.

This skill guides the development of robust, high-performance asynchronous Rust applications. It covers essential production patterns using the Tokio runtime, including managing tasks, streams, channels, and proper async error handling. Ideal for implementing concurrent network services or optimizing complex async I/O logic.

Expert in writing, reviewing, and debugging idiomatic Rust code. This skill covers deep systems programming concepts, including mastering ownership, lifetimes, and borrowing patterns for guaranteed memory safety. Specializes in building high-performance, concurrent async applications using Tokio, and designing robust APIs using advanced trait hierarchies. Ideal for projects requiring zero-cost abstractions and maximum reliability.

This skill provides patterns and implementation templates for managing complex, long-running business processes across multiple independent services. It focuses on implementing the Saga pattern, ensuring data consistency in microservices architectures. It defines clear states, handles step execution, and crucially includes compensation logic to reliably roll back changes when any part of the workflow fails.

Basic Text Processor provides word/character statistics, simple text transformations, batch file handling, and dual JSON or human-readable outputs to demonstrate a CLAUDE skill template.

This skill involves designing and implementing websites where scrolling is treated as a narrative device, transforming simple navigation into a cinematic, delightful user journey. Expertise covers scroll-driven animations, parallax storytelling, interactive reveals, and sticky sections. It requires a deep understanding of front-end performance optimization, balancing high visual impact with smooth, performant user interaction across devices.

This skill helps in deriving actionable security requirements directly from threat models and business contexts. It is essential for translating identified security threats into concrete, verifiable requirements, writing robust security user stories, building comprehensive test cases, and mapping compliance needs into architectural documentation.

A specialized skill for conducting comprehensive security audits, including SAST scans, penetration testing, and dependency analysis. It identifies vulnerabilities across code, infrastructure, and cloud environments, generating structured reports with severity ratings (CVSS) and actionable remediation guidance. Essential for DevSecOps and compliance.
