Skill UI

Master comprehensive evaluation strategies for LLM applications, covering automated metrics like BLEU and ROUGE, human evaluation dimensions, and LLM-as-Judge patterns. This skill helps measure performance, compare models, detect regressions, and validate prompt improvements. Includes Python implementation examples for metrics and evaluation suites.

Generates, compares, and integrates multiple production-ready UI component variations using Magic by 21st.dev. Delivers modern, responsive TypeScript components inspired by premium design patterns like Shadcn UI, Magic UI and Tailwind CSS.

This comprehensive guide details how to configure, integrate, and troubleshoot live email sending using Mailtrap. It covers two primary methods: the Email API (REST) and SMTP. Learn the differences between core email streams—transactional (app-generated notifications), bulk (promotional marketing), and batch requests (high-volume efficiency)—along with recommended integration patterns and specific technical endpoints.

This skill provides comprehensive guidance on Makepad 2.0's Domain Specific Language (DSL) syntax for building UI code. It covers key rules like property assignment, named instances, merge operators, and registration patterns. Use this when developing or debugging Makepad applications to understand the runtime script_mod! macro and Splash scripting language.

This skill assists developers in writing and understanding Makepad DSL code for the Rust makepad-widgets crate. It covers syntax rules, object definitions, inheritance patterns, property overriding, and linking Rust structs to UI prototypes. Use it for live_design! macro implementation, widget composition, and UI styling within Makepad applications.

Expert guidance on Makepad event and action handling, covering Event enum variants, Hit processing, widget actions, and patterns for widget-to-parent communication. Suitable for UI interaction, lifecycle, and input event handling in Makepad applications.

Expert skill for Makepad shader system development. Generate shader code, debug custom drawing, implement SDF-based visuals, and work with GPU-rendered widget appearance. Supports draw_bg, Sdf2d, gradients, effects, and Makepad-specific shader patterns and APIs. Includes vertex and fragment shader functions with built-in GLSL utilities.

Provides guidance for developing Makepad UI in Rust, covering setup, patterns, shaders, packaging, and troubleshooting. Helps identify relevant tools and workflows for building cross-platform applications.

A Rust-based UI framework skill for creating and working with Makepad widgets. Covers core widgets like View, Button, Label, and advanced components for building desktop applications with rich user interfaces. Includes documentation patterns, widget traits, and built-in widget references for UI development.

Expert skill for building Model Context Protocol (MCP) servers and tools from scratch. Covers the full development lifecycle—from defining tool schemas and resources to implementation, testing, and publishing to registries. Supports robust patterns using TypeScript and Python for integrating custom capabilities into AI agents.

This skill provides a comprehensive framework for mastering microservices architecture patterns. It covers critical aspects of building robust, distributed systems, including defining service boundaries (Domain-Driven Design), managing inter-service communication, handling distributed data transactions, and implementing various resilience patterns (e.g., circuit breaker, circuit breaker). It is essential for large-scale system decomposition.

A comprehensive mobile design skill enforcing mobile-first, touch-first, platform-respectful principles. It includes a feasibility risk index, mandatory thinking before work, reference reading requirements, and hard bans on performance, UX, and security anti-patterns. Ideal for designing or building mobile apps with optimal user experience and performance.
