Create or refactor a .NET 8 WPF shell for a desktop widget host using CommunityToolkit.Mvvm and a custom viewmodel-first navigation service. Use when working on App.xaml, MainWindow/ShellWindow, shared ResourceDictionaries, runtime Light/Dark theming, or shell layout for widget-style apps. Avoid Prism, Frame navigation, and heavy region managers.
Create a new underwriting agent (assets, credit, collateral) following established patterns. Use when implementing new agents, extending the system with new document analysis capabilities, or understanding how agents work.
Use when converting UI mockups, screenshots, Figma/Sketch designs, wireframes, or building component libraries from design systems into production-ready code
Advanced function patterns including declaration styles, closures, scope chains, hoisting, and this binding. Master function composition and advanced techniques.
Use when working with rEFui (refui) applications where you cannot rely on reading the library source. Covers the retained-mode + signals mental model, DOM/HTML/Reflow renderers, JSX setup (classic pragma vs automatic runtime), directives (on:/class:/style:/attr:/prop:/m: macros), HMR via refurbish/refui/hmr, debugging “UI not updating” issues, and migrating React/Vue/Solid/Svelte patterns to rEFui.
Apply TDD with RED-GREEN-REFACTOR cycles, separate unit tests from integration tests, ensure comprehensive coverage. Apply when writing tests, evaluating test coverage, testing databases, or testing admin flows.
Design game HUDs, menus, and browser-facing frontend surfaces with intentional visual direction and protected playfield space. Use when the user needs polished game UI, low-chrome 3D overlays, menu systems, HUD hierarchy, responsive behavior, or prompt guidance that avoids generic app-like frontend output.
FFmpeg automation for cutting, trimming, concatenating videos. Audio mixing, timeline editing, transitions, effects. Export optimization for YouTube, social media. Subtitle handling, color grading, batch processing. Use for videogen projects, content creation, automated video production. Activate on "video editing", "FFmpeg", "trim video", "concatenate", "transitions", "export optimization". NOT for real-time video editing UI, 3D compositing, or motion graphics.
Evaluate product desirability, market positioning, and emotional resonance—the complement to friction analysis. Assess whether users will WANT a product (not just use it), identity fit, trust signals, and value proposition clarity. Activate on "will they like it", "market positioning", "appeal analysis", "product desirability", "value proposition", "why would someone choose this", "landing page review", "conversion optimization", "messaging strategy". NOT for UX friction analysis (use ux-friction-analyzer), visual design implementation (use web-design-expert), or A/B test setup (use frontend-developer).
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.
Edit an existing connector action (TaskDialog) in a Copilot Studio agent. Modify inputs, outputs, descriptions, connection mode, and other properties using connector definitions as reference.
Reference tables for Copilot Studio YAML authoring: triggers, actions, variables, entities, Power Fx functions, templates. Preloaded by author and troubleshoot agents.
Colyseus multiplayer patterns for Starwards - @gameField decorators, state sync, JSON Pointer commands, room architecture, and avoiding common Colyseus pitfalls; state is source of truth, server authoritative
Provides Tamagui patterns for config v4, compiler optimization, styled context, and cross-platform styling. Must use when working with Tamagui projects (tamagui.config.ts, @tamagui imports).
Dayhoff Atlas accelerates protein design by pairing trillion-token training data with hybrid Mamba-Transformer models for rapid sequence generation and mutation scoring.
Shared cross-cutting guidance for working with Vibe Kit.
Promptions workflows for dynamic control generation, validation, and replay in AI copilots.
Aurora weather forecasting workflows and regional adaptation guidance.
Designs UX and creates wireframes.
Token-efficient codebase navigation through intelligent symbol loading and querying. Use this skill when implementing new features (find existing patterns), exploring codebase structure, searching for components/functions/types, or understanding architectural layers. Reduces token usage by 60-95% compared to loading full files. Layer split enables 50-80% additional backend efficiency.
