Resolves React hook violations (rules of hooks, useEffect dependencies, hook ordering).
Design and implement retro/cyberpunk/hacker-style terminal UIs. Covers React (Tuimorphic), SwiftUI (Metal shaders), and CSS approaches. Use when creating terminal aesthetics, CRT effects, neon glow, scanlines, phosphor green displays, or retro-futuristic interfaces.
Comprehensive growth strategy expertise combining SEO/SMO/CRO implementation, marketplace and network effects frameworks (Andrew Chen), growth loops methodology (Brian Balfour/Reforge), and Silicon Valley growth thinking. Use when building growth strategy, designing growth loops, improving SEO/SMO/CRO, planning acquisition channels, building network effects, or scaling product-led growth. Growth is not marketing — it's systematic application of product, engineering, and data.
Performs pseudo-mutation analysis on .NET production code to find gaps in existing test suites. Use when the user asks to find weak tests, discover untested edge cases, check if tests would catch a bug, or evaluate test effectiveness through mutation-style reasoning. Analyzes production code for mutation points (boundary conditions, boolean flips, null returns, exception removal, arithmetic changes) and checks whether existing tests would detect each mutation. Works with MSTest, xUnit, NUnit, and TUnit. DO NOT USE FOR: writing new tests (use writing-mstest-tests), detecting test anti-patterns (use test-anti-patterns), measuring assertion diversity (use assertion-quality), or running actual mutation testing tools.
Rules and formatting guidelines for writing Dart /// API documentation and doc comments. Use when documenting Dart code, writing doc comments for any Dart declaration (libraries, classes, methods, variables, etc.), or when instructed to follow the Effective Dart documentation guidelines.
GLSL shader programming for JARVIS holographic effects
Guidelines for using skills effectively - load relevant skills before complex tasks, not every message
Use when creating frosted glass effects, transparent overlays, or modern glass UI. Covers blur, layering, colored shadows.
Extract, reproduce, and locally replay a single WebGL / WebGPU / Canvas / shader / animated-3D visual effect from a web page — the GPU-rendered surface that DOM/CSS cloning is blind to. Use whenever a page has a WebGL/WebGPU/canvas shader background, animated 3D hero, generative gradient, particle field, or Unicorn Studio / Spline / Three.js effect that must be captured and rebuilt as a runnable local module. This is the GPU track of a site clone (driven by clone-site) but also stands alone. Trigger on "extract this shader", "clone the WebGL background", "port this canvas effect", "rebuild this animated hero", "reproduce this Three.js scene locally". NOT for ordinary DOM/CSS cloning (use dom-clone).
Game audio engineer using Web Audio API for procedural music and sound effects in browser games. Zero dependencies. Use when adding music or SFX to a game.
Help users design and execute platform business strategies. Use when someone is building a marketplace, creating an ecosystem, deciding on API strategy, thinking about multi-sided network effects, or building developer platforms.
When the user wants to design product-driven viral growth -- including invite mechanics, collaboration loops, embedding loops, or network effects. Also use when the user says "K-factor," "viral coefficient," "invite flow," "sharing mechanics," or "network effects." For structured referral programs, see referral-program. For growth loop design, see growth-loops.
