Skill UI

This skill provides a comprehensive, structured workflow for diagnosing performance bottlenecks in SwiftUI applications. It guides users through a code-first review to detect common issues like invalidation storms, layout thrash, or heavy main-thread work. When code review is insufficient, it provides detailed guidance on collecting runtime evidence using Instruments, enabling precise root cause analysis and targeted remediation strategies.

Apply proven SwiftUI UI patterns for navigation, sheets, async state, and reusable screens. Learn state ownership, dependency injection, and anti-patterns to build efficient iOS and macOS applications.

A comprehensive guide detailing how to refactor large, complex SwiftUI views into smaller, more stable, and explicit components. It emphasizes adopting a lightweight state approach (favoring local state and environment variables over excessive view model layers) to improve data flow, readability, and overall code maintainability in modern iOS development.

A comprehensive guide to implementing the Swiss Design (International Typographic Style). This style emphasizes absolute mathematical grids, clean sans-serif typography (like Helvetica), and asymmetrical layouts. It is ideal for users requiring highly structured, minimal, and objective visual communication across web and mobile platforms.

A comprehensive style guide for implementing the Synthwave and Outrun aesthetic across web and mobile applications. This guide details the core principles, including dark mode backgrounds, glowing neon accents (magenta, cyan), and the signature perspective grid. It provides technical examples using CSS, SwiftUI, Flutter, and React Native to achieve authentic retro-futuristic visual fidelity.

This skill guides the creation of production-ready design systems using Tailwind CSS. It covers advanced topics such as implementing design tokens, managing component variants, establishing responsive patterns, and ensuring high accessibility standards. Use this when building component libraries, applying theming, or standardizing UI patterns across a large codebase.

Execute a comprehensive Test-Driven Development (TDD) workflow enforcing the red-green-refactor discipline. This skill guides test-first development through coordinated agent orchestration, covering requirements analysis, unit test creation, implementation, refactoring, and integration testing with strict coverage thresholds.

Guides the TDD red phase by generating comprehensive failing tests that define expected behavior, edge cases, and error handling across multiple frameworks (Jest, pytest, JUnit, Go, RSpec). Ensures failures are meaningful and test isolation.

This skill transforms the current workspace into a comprehensive, stateful teaching environment. It guides the user through deep, multi-session learning by structuring content into core components: a defined mission, reference materials, curated resources, structured lessons, and continuous learning records. It employs educational best practices (spaced repetition, retrieval practice) to ensure long-term knowledge retention.

A comprehensive reference guide for selecting core infrastructure technologies including databases, caching, message queues, and API protocols. Helps architects and developers make informed decisions based on scale, consistency, and specific use cases to optimize system design.

Expert guide for building durable distributed systems with the Temporal Go SDK, covering deterministic workflow rules, mTLS worker configuration, advanced patterns, and testing/observability strategies for production workloads.

This skill provides comprehensive testing approaches for Temporal workflows using pytest. It covers unit testing with time-skipping, integration testing with mocked activities, and replay testing for determinism validation. Resources guide local development setup, CI/CD integration, and achieving high code coverage targets. Ideal for validating Python SDK workflows efficiently.
