Automates Foursquare workflows through Composio's Rube MCP toolkit, guiding discovery of current tool schemas, connection checks, and execution steps so integrations stay schema-compliant.

This guide teaches developers how to achieve type-safe and predictable error handling in TypeScript using functional programming concepts from fp-ts, specifically focusing on the Either and TaskEither patterns. Instead of relying on disruptive try/catch exceptions, this pattern treats errors as explicit data values, forcing the calling code to handle failure paths, which is crucial for building robust, maintainable, and functional APIs and services.

A practical, jargon-free guide to applying functional programming principles using the fp-ts library in TypeScript. It teaches essential patterns like `pipe`, `Option`, `Either`, and `flatMap` to handle null checks, errors, and complex data transformations in a clean, maintainable, and robustly functional way. Ideal for developers looking to refactor imperative code.

This skill acts as a specialized expert for transitioning codebases across various frameworks, languages, versions, and platforms. It generates detailed migration plans, automated migration scripts, comprehensive risk assessments, and rollback strategies. Use it when upgrading technology stacks or moving code between disparate systems to ensure minimal disruption and maintain core functionality.

This skill acts as an expert dependency manager, specializing in planning and executing safe, incremental upgrades for project dependencies. It provides comprehensive risk assessment, compatibility analysis, step-by-step migration guides, and robust testing/rollback plans to ensure system stability during major framework updates.

Automates Fraudlabs Pro workflows through Rube MCP/Composio, guiding you to discover current schemas, validate toolkit connections, and run schema-compliant multi-tool executions safely in each session.

Automate FreshBooks operations to list businesses, manage projects, and track time/budgets for SMB accounting workflows via the Rube MCP-backed toolkit.

Automate Freshservice ITSM workflows via Rube MCP and Composio toolkits, covering ticket search, creation, bulk updates, service requests, and email-triggered tickets while retrieving current schemas before each call.

Mastery of modern frontend development using React 19+ and Next.js 15. This skill covers building scalable, high-performance user interfaces, managing complex client-server state, implementing advanced features like Server Components (RSC), and ensuring WCAG accessibility compliance. Ideal for architecting full-stack web applications and optimizing Core Web Vitals.

This expert specializes in scaffolding complete, production-ready, accessible, and performant React and React Native components. It generates full boilerplate code including TypeScript definitions, unit tests, styles (CSS Modules, Styled-Components, Tailwind), and accessibility hooks, ensuring adherence to modern best practices for scalable frontend architecture.

This skill acts as a comprehensive security scanner specializing in detecting Cross-Site Scripting (XSS) vulnerabilities in client-side code. It performs static analysis across React, Vue, Angular, and vanilla JavaScript, specifically identifying unsafe practices like direct HTML manipulation (innerHTML), raw rendering (v-html), and insecure URL handling. Use it when auditing frontend code for security flaws and needing best practices for secure coding.

An expert skill dedicated to building secure, robust frontend applications. It specializes in preventing client-side vulnerabilities such as XSS and clickjacking. Core capabilities include safe DOM manipulation, implementing Content Security Policy (CSP), advanced input sanitization (allowlisting), and securing complex interactions like secure redirects and session management.
