Skill UI

A comprehensive guide detailing idiomatic and efficient coding practices for Kotlin, covering modern features like null safety, functional collections, coroutines, and Jetpack Compose UI development. Learn to write clean, concise, and robust Kotlin code.

A comprehensive guide detailing modern, idiomatic, and efficient patterns for TypeScript and JavaScript development. It covers essential best practices from array manipulation (map, reduce) and destructuring to advanced asynchronous handling (async/await, Promise.all) and type safety best practices, helping developers write cleaner, more robust, and performant code.

This skill generates a comprehensive and structured developer onboarding document for any service or codebase. It guides new engineers through the entire product lifecycle, covering architectural overview, local development setup, key coding patterns, testing strategies, CI/CD deployment processes, and team contacts, ensuring rapid productivity from day one.

This comprehensive guide walks new engineers through setting up a complete local development environment from scratch. It covers all necessary prerequisites, including installing required tools (Git, Docker, Go, etc.), cloning repositories, configuring environment variables, and running initial tests. The goal is to ensure a consistent, working environment and allow new team members to start contributing code quickly and confidently.

This skill provides comprehensive guidance for developing professional, interactive, and distributable Power BI developer visuals (.pbiviz). It covers the entire workflow using the pbiviz toolchain, including scaffolding the project, implementing the IVisual class using TypeScript, managing the formatting model, live-previewing, packaging, certifying, and finally publishing the visual to AppSource.

This skill guide provides comprehensive implementation details for the Metro/Modern UI style, mimicking the aesthetic of Windows Phone/8 start screens. It focuses on creating sharply cornered, flat-color tiles arranged in a horizontally scrolling grid. Key features include live data updates (e.g., tile flipping) and replicating the classic interactive 'tilt' effect. Applicable for cross-platform development using Web (CSS), iOS (SwiftUI), and Flutter.

This guide details the principles and technical implementation of widget-based user interfaces, mimicking the aesthetic of modern mobile operating systems (like iOS Home Screen). It covers core design principles such as strict aspect ratios, glanceability, and corner radius matching. Practical code examples are provided for Web (CSS Grid), iOS (SwiftUI), and Cross-platform (Flutter) development, enabling designers to create modular, highly functional mini-apps.

A comprehensive skill for systematically building, refining, and documenting a project's domain model. It helps define core terminology, establish a ubiquitous language, and record critical architectural decisions (ADRs). Use this when you need to challenge ambiguous language, invent edge-case scenarios, or maintain architectural consistency throughout the development lifecycle.

Use Mailtrap Email Sandbox to capture and inspect outbound emails without sending them to real recipients. This is crucial for development, staging, and CI/CD environments. It allows developers to test email content, headers, attachments, and spam scores using dedicated APIs, SMTP settings, or SDKs, ensuring mail integrity before deployment. Ideal for automation and rigorous quality checks.

This skill scaffolds the necessary configurations for advanced engineering workflows. It guides the user through setting up the issue tracking system (GitHub, GitLab, or local markdown), defining the canonical triage label vocabulary, and establishing the domain documentation context (single or multi-context). It must be run once to initialize the repository for subsequent agent-driven development skills.

This tool evaluates how thoroughly a feature implementation meets product requirements (PRDs) or specifications. It scores acceptance criteria case-by-case, independently grading both the code implementation and the associated test coverage (unit and E2E). Ideal for benchmarking multiple development efforts, auditing adherence to specifications, or determining if a feature is 100% complete and compliant with the ground truth PRD.

This skill guides the systematic triage of project issues and external pull requests (PRs). It moves development items through a defined state machine using roles (e.g., bug, enhancement) and states (e.g., ready-for-agent, wontfix). The process involves context gathering, cross-codebase verification, deep questioning (grilling), and generating comprehensive, agent-ready briefs or marking them for human implementation.
