Guide for implementing Next.js - a React framework for production with server-side rendering, static generation, and modern web features. Use when building Next.js applications, implementing App Router, working with server components, data fetching, routing, or optimizing performance.

Collaborative brainstorming partner for multi-session ideation projects. Use when the user wants to brainstorm, ideate, explore ideas, or think through problems—whether for SaaS products, software tools, book ideas, newsletter content, business strategies, or any creative/analytical challenge. Handles session continuity across days/weeks via versioned markdown documents. Includes brainstorming methods catalog and supports both connected (cross-project awareness) and clean-slate modes.

Comprehensive Ruby development skill covering language fundamentals, object-oriented design patterns, error handling strategies, performance optimization, modern Ruby 3.x features (pattern matching, ractors, typed Ruby), testing patterns, metaprogramming, concurrency, and Rails-specific best practices. Use when writing Ruby code, refactoring, implementing design patterns, handling exceptions, optimizing performance, writing tests, or applying Ruby idioms and conventions.

Core development patterns and architecture for PepMetrics. Use when building features or understanding the codebase.

Generate comprehensive implementation guides for coding tasks instead of writing code directly. Use when the user requests detailed implementation documentation, step-by-step development guides, or when they want to implement features themselves using tools like Cursor. Creates exhaustive guides with background context, architecture decisions, milestones with verification points, and rationale for a "build-it-yourself" workflow.

Implement robust error handling with user-friendly messages, proper exception types, and graceful degradation. Use this skill when writing try-catch blocks, defining custom exceptions, or handling failures from external services. When implementing retry strategies, cleaning up resources, or designing centralized error handling. When validating preconditions or failing fast with clear error messages.

Create components and pages following the Family Gifting Dashboard "Soft Modernity" design system. Use when building UI components, pages, or implementing design specifications. Includes Apple-inspired warmth, generous radii, diffused shadows, and token-optimized styling.

Use when user mentions bookmarks, knowledge management, notes, saving URLs, or taking screenshots - provides quick reference for km (Zettelkasten notes), bookmark (URL manager), and shot-scraper (automated website screenshots) CLI tools installed on this system

Generate SEO-optimized code snippets for websites. Use when asked to optimize SEO, generate meta tags, create structured data (JSON-LD/schema.org), fix heading hierarchy, or audit page SEO. Outputs implementation-ready code for handoff to developers. Supports multilingual sites (Ukrainian/English) and industry-specific schemas for construction equipment, aquaculture, and engineering services.

This skill should be used when designing agent coordination, implementing context handoffs, reducing context overhead, creating multi-agent workflows, optimizing agent communication, implementing progressive disclosure, selecting architectural patterns (hierarchical vs swarm), or debugging agent context issues. Provides SOTA patterns for multi-agent systems achieving 78%+ context reduction while maintaining analysis quality.

Expert RPG map creation and generation for tabletop and online games. Specializes in creating visual descriptions and optimized prompts for z-image turbo model in ComfyUI. Covers all map types (world/continent, regional/local, battle/encounter, dungeon/interior) across multiple themes and settings (fantasy, sci-fi, cyberpunk, post-apocalyptic, horror, etc.). Use when Claude needs to: (1) Create RPG maps of any type, (2) Generate image prompts for map visualization in ComfyUI, (3) Design environments, biomes, settlements, or tactical battlefields, (4) Provide expert knowledge of cartography, terrain, and world-building for games, (5) Convert map descriptions into optimized prompts for image generation models, or (6) Help with any map creation or visualization for tabletop RPGs, video games, or online play.

Capture bugs/enhancements/ideas to request-logs. For quick operations use /mc command instead.

Use when animation excludes users with vestibular disorders, cognitive disabilities, or assistive technology needs

Analyze branch divergence, detect potential conflicts, and guide merge resolution for any Git repository. Auto-detects current branch or accepts parameters.

Breaks cryptographic systems and decrypts ciphertext. Use when working with RSA, AES, XOR, classical ciphers, hash functions, or when challenge involves encryption, decryption, keys, or mathematical crypto attacks.

Common RPA automation patterns (retry, polling, circuit breaker) for resilient automation. Use when: implementing RPA workflows, error handling, resilient automation, retry with backoff, polling for conditions, circuit breaker patterns.

Understand and maintain HuleEdu documentation and task documentation structure. Guides placement, naming, and validation using the canonical specs and management scripts.

Use when implementing UI features in Atomic CRM - enforces design system consistency with Tailwind v4 semantic utilities, desktop-first responsive design, JSONB array patterns, and accessibility standards before writing component code

This skill should be used when confirming implementation matches spec exactly. Use when the orchestrator invokes phase 3 (verify) or when validating completed code against requirements.

Use this skill whenever the user wants to analyze, improve, or enforce performance best practices in a Next.js (App Router) + TypeScript + Tailwind + shadcn/ui project, including bundle size, data fetching, caching, streaming, images, fonts, and client/server boundaries.
