Skill UI

This guide provides practical implementation steps for ensuring GDPR compliance in data processing, consent management, and privacy controls. Use this skill when developing systems that handle EU personal data, managing Data Subject Requests (DSRs), or designing privacy-first architectures to meet strict international data regulations.

GraphQL enables clients to request precise data structures through a single endpoint with a typed schema. This skill covers schema design, resolvers, DataLoader optimization, federation for microservices, and client integration tools like Apollo. It emphasizes treating the schema as a contract and understanding when to use GraphQL versus REST for complex data relationships.

This skill conducts relentless interviews about plans or designs to stress-test them before building. It resolves uncertainties by walking through the design tree and asking questions one at a time. It helps clarify requirements and dependencies before execution, ensuring the plan is robust.

This skill provides guidance on Apple's Human Interface Guidelines for designing user interfaces across different Apple platforms including iOS, iPadOS, macOS, tvOS, visionOS, and watchOS. It covers key principles like touch-first interaction for mobile, pointer and keyboard usage for desktop, and spatial interaction for visionOS. It helps developers and designers adapt layouts, navigation, and interactions to match platform conventions and user expectations, ensuring a native feel and consistent brand experience.

This skill creates or updates a shared Apple design context document for other HIG skills. It auto-discovers project details from code and assets, then gathers information on product overview, platforms, technology stack, design system, accessibility, and user context. The output is a structured markdown file used to tailor subsequent design guidance.

This skill is designed to detect and rewrite text that exhibits common characteristics of AI-generated Chinese writing, such as rigid structures, mechanical connectors, and over-polished phrasing. It helps users 'de-AI' their content by restoring natural human rhythm. Key use cases include reducing AIGC signals in academic papers (for CNKI/VIP checks), and converting the writing tone to specific styles like Zhihu, Xiaohongshu, or literary prose.

This skill enables the identification and exploitation of client-side DOM vulnerabilities, including DOM Clobbering, PostMessage bypasses, Service Worker abuse, and CSS exfiltration. It is designed for authorized security assessments to discover high-value attack chains that bypass server-side filters. Users must obtain explicit written permission before testing any target.

This skill identifies session management vulnerabilities like session fixation, failure to invalidate sessions after logout or password changes, and weak session ID generation. It is designed for authorized security assessments to prevent Account Takeover (ATO) and unauthorized access. Users must obtain explicit written permission before testing targets.

A comprehensive icon library and AI-driven icon generation skill for premium UI/UX design. Use it to pick coordinated Linear, Bold, Bulk, or Two-tone icon styles, generate custom icons when none exists, and integrate them as SVGs or web components with consistent sizing and alignment.

This skill specializes in creating high-impact portfolios that convert visitors into job opportunities or clients. It covers developer, designer, and creative portfolios, focusing on UX, personal branding, and conversion optimization. The expert balances creativity with usability to ensure memorable experiences within the critical 30-second impression window. Ideal for users needing to showcase work effectively.

Invariant-Guard enforces a correctness-first approach to algorithm design. Instead of writing code and hoping it works, this skill mandates defining the function contract, loop invariants, termination arguments, and all potential edge cases *before* implementation. It is essential for complex algorithms where subtle bugs (like off-by-one errors or missed post-conditions) are common, ensuring mathematically rigorous and verifiable code.

An elite advisory skill designed for CTOs, IT Managers, and digital leaders. It acts as a collective intelligence of eight experts, providing comprehensive guidance on modern IT strategy, governance, and operational excellence. Core capabilities include FinOps management, AI governance roadmapping, C-suite executive communication, and aligning technology investments with core business value.
