This skill should be used when implementing non-trivial software features that require planning, review, testing, and documentation. It orchestrates a team of specialized development agents (Groucho, Chico, Zeppo, Harpo) through a rigorous 7-phase workflow to ensure features are properly architected, implemented, reviewed, verified, and documented. Use this skill for multi-file features, new functionality, or any work where quality and thoroughness matter. Do not use for trivial single-line fixes or quick experimental prototypes.

This skill should be used when the user asks to "create a slash command", "add a command", "write a custom command", "define command arguments", "use command frontmatter", "organize commands", "create command with file references", "interactive command", "use AskUserQuestion in command", or needs guidance on slash command structure, YAML frontmatter fields, dynamic arguments, bash execution in commands, user interaction patterns, or command development best practices for Claude Code.
This skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.
