Pyspark Transformer - Auto-activating skill for Data Pipelines. Triggers on: pyspark transformer, pyspark transformer Part of the Data Pipelines skill category.
World-class color theory expertise combining the scientific precision of Josef Albers' "Interaction of Color," the systematic thinking of color systems from Pantone and RAL, and the perceptual psychology insights from researchers like Bevil Conway. Color is not just aesthetics - it's communication, emotion, and usability compressed into wavelengths. Great color work is invisible when done right. Users don't notice "nice colors" - they notice when they can't read text, when buttons don't look clickable, when errors don't feel urgent, or when the interface feels "off" without knowing why. Color theory is the science of making the right thing feel obvious. Use when "color theory, color palette, color scheme, color harmony, complementary colors, analogous colors, contrast ratio, dark mode colors, light mode, color tokens, semantic colors, color accessibility, color blindness, color psychology, color system, brand colors, data visualization colors, color, design, accessibility, contrast, dark-mode, theming, tokens, wcag, palette, harmony" mentioned.
Master React Navigation - stacks, tabs, drawers, deep linking, and TypeScript integration
Framework-agnostic frontend security guide based on OWASP Secure Coding Practices. Covers XSS prevention, CSRF protection, Content Security Policy (CSP), secure cookie configuration, client-side authentication patterns, input validation, secure storage, and security headers. Activates for security audits, vulnerability reviews, or browser security questions in any web application. NOT for backend/NestJS security (use generating-nest-servers). NOT for Nuxt-specific implementation (use developing-lt-frontend).
AI-simulated event storming workshop with multi-persona support. Use when discovering domain events, commands, actors, and bounded contexts. Supports three modes - full-simulation (5 persona agents debate), quick (single-pass analysis), and guided (interactive with user). Orchestrates persona agents and synthesizes results.
Guide for conducting comprehensive accessibility audits of code to identify WCAG compliance issues and barriers to inclusive design. This skill should be used when reviewing accessibility, ARIA implementation, keyboard navigation, or screen reader compatibility.
Use when implementing async operations with Kotlin coroutines, Flow, StateFlow, or managing concurrency in Android apps.
Use when FastAPI validation with Pydantic models. Use when building type-safe APIs with robust request/response validation.
Unvarnished technical criticism combining Linus Torvalds' precision, Gordon Ramsay's standards, and James Bach's BS-detection. Use when code/tests need harsh reality checks, certification schemes smell fishy, or technical decisions lack rigor. No sugar-coating, just surgical truth about what's broken and why.

This skill should be used whenever domain modeling is taking place. It provides specialized guidance for type-driven and data-driven design based on Rich Hickey and Scott Wlaschin's principles. The skill helps contextualize current modeling within the existing domain model, identifies inconsistencies, builds ubiquitous language, and creates visualizations (Mermaid, Graphviz/DOT, ASCII diagrams) to communicate domain concepts clearly. Use this skill when designing types, modeling business domains, refactoring domain logic, or ensuring domain consistency across a codebase.
