Diagnoses and resolves issues with Flux GitOps deployments, Kubernetes pods, services, and HelmReleases in the Superbloom cluster

Create forms, validation schemas, and CRUD API endpoints. Use when building new data entry features or managing existing forms.

Design learning materials for right-to-left languages, complex scripts, bidirectional text, and multi-script environments. Calculate text expansion factors and specify typography requirements. Use when creating content for Arabic, Hebrew, Asian scripts, or mixed-direction text. Activates on "RTL", "right-to-left", "bidirectional text", or "complex scripts".

Designs and documents control testing procedures. Creates test plans, executes walkthroughs, and documents results for audit workpapers.

Essential Linux command line commands for navigation, file management, and daily tasks. Includes Windows equivalents. Use when the user needs to learn basic terminal commands, file operations, or mentions being intimidated by the command line.

Design command-line interface parameters and UX: arguments, flags, subcommands, help text, output formats, error messages, exit codes, prompts, config/env precedence, and safe/dry-run behavior. Use when you’re designing a CLI spec (before implementation) or refactoring an existing CLI’s surface area for consistency, composability, and discoverability.

Use when design is complete and you need detailed implementation tasks for engineers with zero codebase context - creates comprehensive implementation plans with exact file paths, complete code examples, and verification steps assuming engineer has minimal domain knowledge

Analyze and implement purposeful UI animations for Svelte/SvelteKit + Tailwind projects. Specialized in Svelte transitions, actions, and animation patterns. Use when user asks to add animations, enhance UI motion, animate pages/components, or improve visual feedback. Triggers on "add animations", "animate UI", "motion design", "hover effects", "scroll animations", "page transitions", "micro-interactions".

Interactive browser automation via Chrome DevTools Protocol. Use when you need to interact with web pages, test frontends, or when user interaction with a visible browser is required.

Generate comprehensive handoff documentation optimized for AI agent takeover by analyzing project structure, design docs, and codebase

Try 2-3 different approaches before implementing - don't settle for first design you think of

Frontend development guidelines for Quantum Skincare's Next.js 16 App Router application with React 19.2, Tailwind CSS v4, Clerk authentication, and TypeScript. Covers Server/Client Components, React 19.2 features (useEffectEvent, Activity component, cache signals, React Compiler auto-optimization), data fetching patterns, Tailwind styling, route groups, form validation, and performance optimization. Use when creating pages, components, API routes, styling, or working with frontend code.

Declare new iOS Feature cases by collecting details via interactive form and automatically updating all required files (Feature.swift, FeatureInfo.swift, Localizable.strings, ScreenID, Routes). Use when "add new feature", "declare new feature", "create feature case", "add feature to menu", or "new feature declaration".

Guidance for building fullstack apps with Vite (React + TypeScript) frontend and FastAPI backend. Use when demos need a web UI beyond what Streamlit provides.

Game engines, physics, graphics, networking, and game design patterns.

Create distinctive, production-grade terminal user interfaces with high design quality. Use this skill when the user asks to build CLI tools, TUI applications, or terminal-based interfaces. Generates creative, polished code that avoids generic terminal aesthetics.

Supabase development guidelines for Next.js applications. Use when working with Supabase Auth SSR, database migrations, RLS policies, database functions, Edge Functions, or declarative schema management. Covers @supabase/ssr patterns, PostgreSQL best practices, and Deno-based Edge Functions.

Use the MIDI Markdown Compiler (mmdc) CLI for compiling MMD to MIDI, validating syntax, real-time playback with TUI, exporting to different formats (JSON, CSV, table), and managing device libraries. Use when the user wants to compile, validate, play, inspect MMD files, or work with device libraries.

Build mobile-first, responsive layouts that adapt across screen sizes. Use this skill when implementing breakpoints, fluid layouts, or touch-friendly interfaces. When working on files with media queries, responsive utilities, or layout components. When using rem/em units, percentage widths, or viewport-relative sizing. When optimizing for mobile performance or testing across device sizes.
