Skill UI

A comprehensive reference guide detailing best practices, rules, and optimizations for building high-performance React Native and Expo applications. It covers critical areas such as list virtualization, complex animations, UI patterns, state management, and monorepo structure, helping developers avoid common pitfalls and maximize app speed and stability.

This comprehensive workflow guides the development of modern, scalable full-stack applications using Next.js 14+, React, and TypeScript. It covers all phases, from project setup and component architecture to advanced data fetching (Server Components, React Query), styling with Tailwind CSS, robust testing (E2E via Playwright), and deployment optimization. Ideal for building complex, production-grade web interfaces.

RouterBase acts as a unified, OpenAI-compatible API gateway, allowing applications to route requests across diverse large language models (LLMs) like GPT, Claude, and Gemini. It helps developers migrate existing OpenAI SDK calls, implement sophisticated primary/fallback model selection based on cost, latency, and quality, and manage multimodal payloads (image, audio, video) from a single, standardized endpoint.

This skill enables writing idiomatic Ruby code using metaprogramming, Rails patterns, and performance optimization techniques. It specializes in Ruby on Rails application development, gem creation, and testing frameworks like RSpec. Users can get guidance on best practices, code quality with RuboCop, and architectural patterns for maintainable software.

This skill provides comprehensive guidelines for writing idiomatic and efficient Rust code. It covers key topics such as ownership, borrowing, error handling, iterators, pattern matching, structs, enums, and concurrency. It helps developers avoid common anti-patterns and adopt best practices for production-ready Rust applications.

This skill provides comprehensive, production-grade patterns for asynchronous programming in Rust using the Tokio runtime. It covers essential concepts like tasks, channels, and streams, along with robust error handling techniques. Use it when developing concurrent network services, building complex async applications, or optimizing performance in Rust.

This skill provides expert patterns for Salesforce platform development, covering Lightning Web Components, Apex triggers, REST/Bulk APIs, and External Client Apps. It supports Salesforce DX with scratch orgs and 2nd generation packages. Ideal for developers building scalable solutions on the Salesforce ecosystem.

This skill evaluates code diffs against a specific rubric to determine issue detection and resolution. It reads diff files, rubrics, and original fixtures, then answers detection and fix questions for specific problems. Results are appended to a CSV file. Ideal for automated testing and quality assurance workflows in software development.

Expert security auditor for DevSecOps, application security, and compliance. Performs threat modeling, vulnerability assessment, secure code review, and CI/CD security integration to build resilient, compliant systems.

Coordinate multi-layer security scanning and hardening across application, infrastructure, and compliance controls using defense-in-depth strategy. Orchestrates specialized security agents for comprehensive assessments, layered controls, and continuous monitoring. Follows DevSecOps principles with shift-left security, automated scanning, and compliance validation to create a resilient security posture addressing vulnerabilities and future threats.

A comprehensive REST API for sending and receiving multi-channel messages, including iMessage (blue bubbles), SMS, and RCS. This skill allows developers to integrate messaging capabilities into server-side applications, supporting advanced features such as group messaging, reactions, typing indicators, and status callbacks. It also handles inbound messages via webhooks, making it ideal for building robust, real-time communication services that require programmatic control over messaging lifecycles.

This specialized skill guides users through a structured, forensic investigation process when facing sudden, significant drops in organic traffic or search rankings. It is designed for incident scenarios—such as suspected penalties, Core Updates, major technical regressions, or unexplained traffic crashes—providing a systematic approach to triage, root-cause analysis, and developing a prioritized recovery plan.
