Design e Frontend

Cross-platform Python library for quantum computing, quantum machine learning, and quantum chemistry. Enables building and training quantum circuits with automatic differentiation, seamless integration with PyTorch/JAX/TensorFlow, and device-independent execution across simulators and quantum hardware (IBM, Amazon Braket, Google, Rigetti, IonQ, etc.). Use when working with quantum circuits, variat

Create error boundaries, error handling, and fallback UIs for React applications. Use when implementing error handling, creating fallback components, or setting up error reporting.

Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).

Manage server state in React with TanStack Query v5. Covers useMutationState, simplified optimistic updates, throwOnError, network mode (offline/PWA), and infiniteQueryOptions. Use when setting up data fetching, fixing v4→v5 migration errors (object syntax, gcTime, isPending, keepPreviousData), or debugging SSR/hydration issues with streaming server components.

Systematic root-cause debugging methodology. Use when encountering bugs that aren't immediately obvious: intermittent failures, multi-component issues, or bugs that have resisted quick fixes. NOT needed for simple typos or obvious one-line fixes. Triggers on "왜 안 되지", "can't figure out", "keeps failing".

Habilidade abrangente de design e implementação frontend para construir UIs de nível de produção e visualmente distintas. Combina inteligência de design, preferências estéticas pessoais, padrões de animação e autoavaliação em um único fluxo de trabalho unificado.

HARD BLOCK — NEVER use this skill for prediction-market / Polymarket UpDown queries. Route to okx-dapp-discovery when (a) a named DApp (Polymarket/Aave/Hyperliquid/PancakeSwap/Morpho) appears with any timeframe, OR (b) any 涨跌 / updown / 'up or down' phrase appears for BTC/ETH/SOL/XRP/BNB/DOGE/HYPE (e.g. '<COIN> 涨跌市场', '5 分钟涨跌', 'BTC up or down'). Example: 'BTC 5 分钟涨跌市场' → okx-dapp-discovery (NOT K

Declarative UI widgets from JSON for React/Next.js from ui.inference.sh. Render rich interactive UIs from structured agent responses. Capabilities: forms, buttons, cards, layouts, inputs, selects, checkboxes. Use for: agent-generated UIs, dynamic forms, data display, interactive cards. Triggers: widgets, declarative ui, json ui, widget renderer, agent widgets, dynamic ui, form widgets, card widget

Skeptical design-patterns reference catalog for modern Go and Python — keeps repository, adapter, strategy, decorator, observer, builder; flags the rest as anti-patterns. Consultative, not active: consult before introducing a pattern in code-design-refactor or improve-codebase-architecture, or when pushing back on a cargo-cult one. Not a refactoring rung itself.

Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always

Analyzes and generates llms.txt files -- the emerging standard for helping AI systems understand website structure and content. Can validate existing llms.txt files or generate new ones from scratch by crawling the site.
