Frontend

This skill should be used when the user asks to "choose between skill and agent", "compose multi-agent system", "orchestrate agents", "manage agent context", "design component architecture", "should I use a skill or agent", "when to use hooks vs MCP", "build orchestrator workflow", needs decision frameworks for Claude Code components (skills, sub-agents, hooks, MCP servers, slash commands), context management patterns, or wants to build effective multi-component agentic systems with proper orchestration and anti-patterns guidance.
