Skill UI

Design and evaluate LLM product features, retrieval, validated outputs, latency, and cost controls. Covers LLM integration patterns, RAG architecture, scalable prompt engineering, trustworthy AI UX, and cost optimization strategies for sustainable AI implementation in production environments.

This skill provides guidelines for senior backend engineers building production-grade services using Node.js, Express, and TypeScript. It covers layered architecture, error handling, validation with Zod, configuration management, and directory structure to ensure maintainability and reliability.

A workflow for building features guided by data insights, A/B testing, and continuous measurement, covering exploratory data analysis, hypothesis formation, experiment design, analytics instrumentation, and implementation.

This comprehensive workflow covers the entire database lifecycle, including design, implementation, optimization, migration, and data engineering. It supports SQL and NoSQL technologies like PostgreSQL and MongoDB. Key phases include schema design, ORM setup, query performance tuning, data pipeline creation, quality assurance, and operational management. Ideal for developers and data engineers managing modern data platforms.

This skill covers the full lifecycle of Docker containers, including building optimized images, managing container lifecycles, configuring networking and volumes, and implementing security best practices. It includes troubleshooting container issues, debugging, and deploying applications efficiently in development and production environments using Docker Engine commands and best practices.

This skill guides users in designing and reviewing polished user interfaces with a focus on animation, interaction feedback, component craftsmanship, and accessibility. It helps implement motion reviews and ensure keyboard accessibility and reduced-motion behavior. Suitable for frontend development tasks requiring high-quality UI polish and adherence to safety boundaries.

This skill enforces strict architectural and performance standards for senior frontend engineers. It guides the creation of scalable React applications using Suspense-first data fetching, feature-based organization, and strict TypeScript discipline. Use it when building components, adding features, fetching data, or refactoring code to ensure maintainability and performance.

Orchestrates game development projects by routing to specialized sub-skills based on platform, dimension, and engine fit. Covers core principles like game loop, pattern selection, input abstraction, performance budgets, AI, and collision strategies. Use when starting or structuring a game project, choosing frameworks, or picking among Phaser, PixiJS, Kaplay, Three.js, Godot, Unity, and more.

This system treats ideas like living species on an 'evolution island.' Instead of simple storage, it runs structured, multi-round iterations simulating biological processes: competition, crossbreeding, and mutation. Users input initial concepts, and the tool systematically evaluates them using a 6-dimensional scoring framework (Novelty, Feasibility, Value, etc.). It helps users deepen viability, discover unexpected connections between disparate ideas, and prioritize the most robust concepts for development and investment.

This skill simulates a highly advanced 'Board of Experts,' consulting multiple specialized personas (e.g., Musk, Buffett, Jobs) simultaneously. It gathers distinct, multi-perspective analyses on any complex topic—from engineering feasibility to market strategy—and synthesizes them into a single, comprehensive, and actionable decision. Ideal for complex strategic planning, product development, and high-stakes investment decisions.

Open Dynamic Workflows (ODW) is an advanced, open-source engine designed to manage complex coding tasks using multiple AI agents. It operates in three stages: planning the task into parallel subtasks, orchestrating various coding agents (like Codex or Antigravity) to work concurrently, and finally, performing an adversarial verification pass to challenge and validate the combined output before merging. It supports multiple model providers and is ideal for structured, high-reliability software development.

Engine selection and platform-specific principles for PC and console games. Covers Unity, Godot and Unreal comparison, Steam and console certification features, controller action mapping, haptics, and profiling-driven performance optimization.
