Expert motion and interaction design auditor with context-aware perspective weighting. \n \n Audits animations, transitions, and hover states through three designer lenses: Emil Kowalski (restraint and speed), Jakub Krehel (production polish), and Jhey Tompkins (playful experimentation) \n Performs motion gap analysis to identify conditional renders and UI state changes missing AnimatePresence or transitions \n Delivers per-designer findings with severity-ranked recommendations, accessibility ch

Language-agnostic reference for SOLID principles, design patterns, DRY, KISS, and clean code fundamentals. \n \n Covers seven rule categories prioritized by impact: SOLID principles, core principles (DRY, KISS, YAGNI), design patterns, code organization, naming, functions, and documentation \n Includes 23 rules across SOLID (5), core principles (8), and design patterns (8), with 4 additional categories planned \n Provides quick reference tables, TypeScript code examples, and an audit output form

You are a senior design engineer specializing in motion and interaction design. When asked to audit motion design, you MUST follow this workflow exactly.

Review animation code for compliance with Disney's 12 principles adapted for web interfaces.

Apply SOLID design principles for maintainable, flexible code architecture.

Framework for effective AI collaboration defining task decomposition, context management, abstraction selection, and automation philosophy. \n \n Divide complex tasks into small, independently verifiable steps; AI performs significantly better with clear, bounded instructions than large ambiguous requests \n Keep context fresh and single-purpose; use separate conversations for different topics and apply HANDOFF.md summaries when conversations grow long to prevent context drift \n Adjust abstract

This skill encodes design principles derived from comparing polished, production-quality SwiftUI apps against poorly-built ones. The patterns here represent what separates an app that feels "right" from one where the margins, spacing, and text sizes just look "off."

Core principles for effective AI agent collaboration: divide tasks, manage context, choose abstraction levels, automate patterns, and validate results. \n \n Decompose large tasks into small, explicit steps; AI performs 39% better on focused instructions than vague, complex requests \n Keep context fresh and single-purpose using separate conversations or HANDOFF.md documentation to avoid context drift and performance degradation \n Switch between high-level \"vibe coding\" for prototyping and de

Master REST and GraphQL API design principles to build intuitive, scalable, and maintainable APIs that delight developers and stand the test of time.

REST and GraphQL API design principles for building scalable, developer-friendly APIs. \n \n Covers resource-oriented REST patterns including HTTP method semantics, URL design, pagination, filtering, and error handling with consistent status codes \n Includes GraphQL schema-first development with type definitions, resolver patterns, Relay-style pagination, and DataLoader implementation for N+1 prevention \n Provides versioning strategies (URL, header, query parameter) and HATEOAS patterns for hy
