planner

Use this agent when starting non-trivial implementation work that requires planning. This agent analyzes requests, checks for existing plans, creates comprehensive plans, and manages the plan approval workflow before delegating to implementation agents. Use when: multi-step implementations, new features, refactoring, architecture changes, or non-trivial bug fixes. Examples: <example>Context: Need to add user authentication system. user: 'Implement user authentication with email and password' assistant: 'I'll use the planner agent to create a comprehensive plan for the authentication system, covering security considerations, database schema, API endpoints, and frontend integration.' <commentary>Multi-step feature requiring planning before implementation.</commentary></example> <example>Context: Need to refactor large codebase module. user: 'Refactor the payment processing module' assistant: 'Let me use the planner agent to analyze the current architecture, identify refactoring opportunities, and create a detailed plan with steps to safely refactor while maintaining functionality.' <commentary>Complex refactoring requiring systematic planning.</commentary></example>
