Design

Collaborative design refinement that transforms rough ideas into fully-formed specifications through Socratic questioning. Explores alternatives, validates incrementally, and presents designs in digestible chunks for feedback. Use before writing code or implementation plans when requirements are unclear or multiple approaches exist. Do NOT use when requirements are already well-defined, you're implementing a known pattern, or making small changes - proceed directly to implementation instead.

Guide newcomers through learnings with patience and context. Use when user says "mentor me", "guide me through", "I'm new to", "help me understand", "walk me through". Auto-trigger when frustration or confusion detected.

Guide for integrating Gemini AI models with Firebase using Firebase AI Logic SDK. This skill should be used when implementing Gemini features (chat, content generation, structured JSON output), configuring security (App Check), or troubleshooting issues (rate limits, schema errors).

Responsive layout considerations using CSS and Javascript. When Claude needs to build responsive, fluid layouts.

Master testing strategies (unit, integration, E2E), security best practices, OWASP Top 10, secure coding, and system monitoring. Learn to write secure code, comprehensive tests, and build resilient systems with proper incident response and compliance.

Design multi-agent workflows with DAGs, state machines, and event-driven patterns

Use for LangGraph agent design and refactors. Prefer explicit state, small nodes, and clear transitions.

Create dbt models following FF Analytics Kimball patterns and 2×2 stat model. This skill should be used when creating staging models, core facts/dimensions, or analytical marts. Guides through model creation with proper grain, tests, External Parquet configuration, and per-model YAML documentation using dbt 1.10+ syntax.

Design emotionally compelling escape room narratives using Danpyeonsun methodology (2024 Korean award winners). Creates 3-act dramatic structures with complex characters, multiple endings, and integrated puzzle-narrative flow. Use when designing story, characters, emotional arcs, or branching narratives for mystery and detective games.

Build specific targets in the nx-std monorepo using just tasks. Use when compiling NRO files, libraries, or other build artifacts.

Analyzes Fulfil order data to determine profitable free shipping thresholds using order value distribution, hero product analysis, and shipping economics. Use when merchants ask about free shipping strategy, threshold optimization, shipping offers, AOV analysis, or need data-driven shipping decisions. Requires access to Fulfil data warehouse (sales_orders, shipments tables).

Create beautiful Rich terminal output with tables, panels, progress bars, and styled text. Use when building terminal UI components.

Use for HTML/CSS layout, responsive behavior, and UI styling on the NestMind site; follow the Zed-inspired design system in css/styles.css and reuse existing patterns.

Look up HVAC equipment specifications (capacity, efficiency, dimensions, electrical requirements) by brand and model number. Use when the user mentions equipment specs, model numbers, AHU, VAV, chiller, boiler, pump, fan specifications, or needs to find manufacturer data sheets. Searches manufacturer websites and processes PDF spec sheets with security safeguards.

Comprehensive Expo expert with access to complete official documentation covering React Native development, EAS Build, EAS Submit, EAS Update, Expo Router, Expo Modules API, configuration, deployment, and all platform features. Invoke when user mentions Expo, React Native, EAS, Expo Router, mobile app development, iOS/Android development, or cross-platform development.

Automatically review documents against checklists and best practices. Use when creating or reviewing ADRs, Design Docs, meeting notes, technical proposals, or RFCs. Detects anti-patterns, vague expressions, and missing elements.

Write academic research documents following academic guidelines with peer-reviewed sources from Google Scholar and other academic databases. Always verify source credibility and generate IEEE standard references. Use for research papers, literature reviews, technical reports, theses, dissertations, conference papers, and academic proposals requiring proper citations and scholarly rigor.
