Skill UI

Optimize Linux system performance by configuring kernel parameters, analyzing bottlenecks, and tuning resources like memory, CPU, and network. Includes monitoring tools and sysctl settings for production environments.

This skill helps plan work by creating a concise Product Development Requirement (PDR) and implementation-sized tasks within the YYLO Ledger system. It reads project instructions, defines scope, risks, and acceptance criteria, then registers tasks using CLI commands. It ensures proper task ownership and dependencies without starting actual implementation or deployment.

Manage containers using Podman's daemonless, rootless container engine. Covers basic commands, pods, systemd integration, networking, storage, and registry configuration for security-conscious environments.

This skill provides expert guidance on writing highly portable shell scripts that adhere strictly to POSIX standards. It teaches users how to avoid shell-specific extensions (like advanced arrays, specific conditionals, or GNU features) to ensure maximum compatibility and robustness across diverse Unix-like systems (Linux, BSD, Solaris, etc.). Ideal for critical infrastructure scripting and environments requiring extreme cross-platform reliability.

Design efficient PostgreSQL schemas using best practices for data types, indexing, and constraints. Covers normalization, partitioning, and performance optimization for scalable database systems.

A comprehensive playbook for optimizing the entire lifecycle of pull requests. It guides developers through systematic pre-flight cleanup, critical self-audits, local test verification, and structuring high-signal PR descriptions to ensure code quality and fast maintainer approval.

This skill autonomously deep-scans entire codebases line-by-line to identify security vulnerabilities, performance bottlenecks, and architectural flaws. It systematically refactors code to meet enterprise-grade production standards, including adding logging, monitoring, CI/CD pipelines, and security hardening. Ideal for preparing software for deployment.

This skill systematically audits a given project by analyzing its historical memory, rollout summaries, and local skill definitions. It identifies repeated complex workflows, recurring operational patterns, or areas where existing skills are stale. The audit process guides the user to recommend the highest-value skills to either add (if a new pattern emerges) or update (if current skills are outdated or incomplete), ensuring the AI agent operates with the most accurate and context-specific knowledge base for optimal project execution.

Configure Prometheus and Grafana for comprehensive metrics collection, visualization, and alerting. This skill covers Docker and Kubernetes deployment, PromQL query writing for analysis, and setting up alerting rules for system performance monitoring. Ideal for DevOps engineers managing infrastructure observability.

Build accessible, production-grade design systems with Radix UI headless primitives. Covers theming strategies, compound component patterns, and WCAG-compliant React component libraries with full styling control.

Generate production-quality React components and UIs using the specialized Rayden UI component library and Tailwind CSS. This skill ensures that all generated code strictly adheres to a defined design system, including correct component usage, design tokens, prop validation, and established layout patterns. Ideal for scaffolding complex pages like dashboards, login forms, and data tables while maintaining premium aesthetics and consistency.

A comprehensive optimization guide maintained by Vercel, covering 45 rules for React and Next.js. Use this resource when building new components, implementing complex data fetching (client or server-side), refactoring code, or systematically improving bundle size and overall load times for high-performance web applications.
