Skill UI

Automate software version management and changelog generation based on Semantic Versioning principles and Conventional Commits. Supports tools like semantic-release and standard-version for CI/CD integration, ensuring consistent release workflows and version precedence.

This skill covers essential principles for managing production servers, focusing on decision-making rather than memorizing commands. It includes process management, monitoring strategies, log handling, scaling decisions, health checks, and security best practices to ensure system stability and reliability.

This skill identifies error-prone APIs, dangerous configurations, and footgun designs that enable security mistakes. It evaluates whether interfaces are resistant to developer misuse, focusing on algorithm selection, default values, primitive types, and configuration cliffs. Use when reviewing API designs, cryptographic library ergonomics, or assessing authentication interfaces to ensure secure-by-default principles are followed.

This skill provides guidance for quality-focused software development and architecture based on Clean Architecture and Domain Driven Design principles. It covers code style rules, best practices like library-first approach, naming conventions, separation of concerns, and avoiding anti-patterns to ensure maintainable and scalable code.

Safely refactor code with a comprehensive TDD safety net: establish a green baseline, detect code smells, apply design patterns and SOLID principles, optimize performance, and verify all tests remain green.

Guidelines for virtual and augmented reality development covering platform selection, comfort, performance, interaction, spatial design, and anti-patterns. Use when designing immersive locomotion, spatial interaction, comfort settings, or measuring frame times on a target headset.

Master advanced vulnerability analysis principles aligned with OWASP 2025 standards. Learn to think like an attacker and defend like an expert. Covers supply chain security, attack surface mapping, risk prioritization using CVSS and EPSS, and exceptional condition handling. Includes methodologies for scanning, code pattern analysis, and cloud security considerations to identify and mitigate critical security risks effectively.

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.

Generate comprehensive onboarding documentation for software engineers ranging from newcomers to principals. This skill creates two complementary guides: a principal-level overview covering architecture, design principles, and decision logs, and a zero-to-hero contributor guide with setup instructions and workflows. It automatically detects programming languages and includes Mermaid diagrams for clarity.

This document provides a comprehensive guide to the principles and vocabulary needed to write high-quality, predictable, and effective skills. It covers advanced concepts like model-invoked vs. user-invoked skills, managing context load, structuring information hierarchies (steps vs. reference), and implementing progressive disclosure to improve agent predictability.

This comprehensive guide provides developers with the foundational principles and actionable code examples for implementing the Y2K aesthetic. Learn how to achieve the signature look—incorporating chrome metallic effects, amorphous blob shapes, digital grid backgrounds, and neon glows—across web (CSS), iOS (SwiftUI), and cross-platform (Flutter) environments.

Shared vocabulary and principles for designing deep modules with small interfaces, clean seams, and testable, AI-navigable codebases.
