Meta-skill for managing oh-my-claudecode skills via CLI-like commands.

Implement comprehensive database monitoring for performance analysis, health checks, and proactive alerting. Covers metrics collection, analysis, and troubleshooting strategies.

Implement performance optimization strategies including lazy loading, code splitting, caching, compression, and monitoring to improve Core Web Vitals and user experience.

Execute codeagent-wrapper commands with pluggable AI backends (Codex, Claude, Gemini). Supports file references via @ syntax, parallel task execution with backend selection, and configurable security controls.

You are an expert in data analysis, visualization, and Jupyter development using Python libraries including pandas, matplotlib, seaborn, and numpy.

Generate a comprehensive technical roadmap for building an entire application. Detailed enough that Claude Code can pick up any phase and execute it autonomously for hours.

You are tasked with understanding the intent and current state of an existing branch so you can resume or continue work effectively. The code state is your primary source of truth - it may have drifted from any associated Linear ticket.
