Skill UI

Provides comprehensive guidance on building robust evaluation frameworks for complex agent systems. It addresses the inherent challenges of non-determinism and multiple valid paths, enabling systematic performance testing, validating context engineering choices, and measuring continuous improvements across multiple quality dimensions (e.g., factual accuracy, tool efficiency).

Expert in event sourcing, CQRS, and event-driven architecture. Masters event store design, projection building, saga orchestration, and eventual consistency. Ideal for systems requiring audit trails, complex workflows, temporal queries, and event-driven microservices.

This skill guides you in designing and implementing event stores for event-sourced systems. It covers architecture patterns, technology selection (like PostgreSQL, Kafka, EventStoreDB), and implementation best practices. Use it when building event sourcing infrastructure, optimizing storage retrieval, or setting up schemas. Includes templates for SQL and Python implementations to ensure append-only, ordered, and versioned event persistence.

Master building high-performance asynchronous APIs using FastAPI, SQLAlchemy 2.0, and Pydantic V2. Covers microservices, WebSockets, security, testing, and deployment strategies for production-ready Python backend systems. Includes async patterns, database optimization, and observability.

Expert firmware analyst for embedded systems, IoT security, and hardware reverse engineering. Extract, inspect, and assess firmware for vulnerabilities using binwalk, UART/JTAG, emulation, and static analysis.

This skill acts as a specialized expert for transitioning codebases across various frameworks, languages, versions, and platforms. It generates detailed migration plans, automated migration scripts, comprehensive risk assessments, and rollback strategies. Use it when upgrading technology stacks or moving code between disparate systems to ensure minimal disruption and maintain core functionality.

This skill orchestrates full-stack feature development across backend, frontend, and infrastructure layers using an API-first approach. It guides users through architecture design, parallel implementation, and integration testing phases, coordinating specialized agents to deliver cohesive, production-ready systems with proper separation of concerns and comprehensive testing.

This skill covers core principles for game audio implementation, including sound design, music integration, and adaptive audio systems. It details audio categorization, layering techniques, 3D spatialization, platform-specific formats, and mix hierarchy to create immersive experiences.

A comprehensive guide to game design covering core loop design, game design documents, player psychology, difficulty balancing, progression systems, and common anti-patterns. Ideal for game developers and designers seeking to create engaging player experiences.

This guide provides practical implementation steps for ensuring GDPR compliance in data processing, consent management, and privacy controls. Use this skill when developing systems that handle EU personal data, managing Data Subject Requests (DSRs), or designing privacy-first architectures to meet strict international data regulations.

Analyzes and generates llms.txt files, the emerging standard that gives AI systems a structured, machine-readable summary of a website's purpose, key pages, and facts. Covers format rules, section conventions, and the extended llms-full.txt variant for AI discoverability.

A production-grade framework for executing high-performance, robust browser automation and web scraping using Playwright with the Go language. This skill specializes in handling complex Single Page Applications (SPAs), emulating human behavior (e.g., random typing delays, Bezier mouse movements), and implementing advanced stealth techniques to bypass anti-bot systems like Cloudflare. It emphasizes architectural best practices, such as using contexts for isolation and structured logging.
