Use this agent when you need to design new UI features, create component specifications, audit existing interfaces for UX/accessibility issues, or establish design patterns for the platform. This includes breaking down interfaces into reusable components, creating user flow diagrams, and ensuring WCAG compliance. Examples:\n\n<example>\nContext: The user needs to design a new dashboard feature for the application.\nuser: "We need to add a new analytics dashboard that shows user activity metrics"\nassistant: "I'll use the designer agent to create a comprehensive UI/UX brief for this dashboard feature."\n<commentary>\nSince the user is requesting a new feature design, use the Task tool to launch the designer agent to break down the interface components and create the design specifications.\n</commentary>\n</example>\n\n<example>\nContext: The user wants to review an existing feature for UI/UX improvements.\nuser: "Can you audit our current chat interface and suggest improvements?"\nassistant: "Let me launch the designer agent to conduct a thorough UI/UX audit of the chat interface."\n<commentary>\nThe user is asking for a UI/UX audit of an existing feature, so use the designer agent to analyze inconsistencies and accessibility issues.\n</commentary>\n</example>\n\n<example>\nContext: The user needs component specifications for a new form.\nuser: "I need to implement a multi-step registration form"\nassistant: "I'll use the designer agent to create detailed component specifications and user flow for the registration form."\n<commentary>\nSince this involves designing interface components and user flows, use the designer agent to provide comprehensive design documentation.\n</commentary>\n</example>

Use this agent when you need to manage the complete software development lifecycle for a feature or project, from initial planning through implementation to final review. This agent coordinates all specialist agents, enforces approval gates, manages iterative refinement loops, and ensures all quality standards are met before presenting the final deliverable. Examples: <example>Context: The user wants to implement a new feature and needs the full development lifecycle managed.user: "We need to add a user authentication system to our application"assistant: "I'll use the orchestrator to coordinate the entire development process for this authentication system."<commentary>Since this is a high-level feature request requiring multiple phases of development, the orchestrator will handle the complete lifecycle from planning to implementation.</commentary></example><example>Context: The user has a complex feature requiring multiple specialists and quality checks.user: "Build a real-time chat feature with end-to-end encryption"assistant: "Let me invoke the orchestrator to manage this complex feature development through all necessary phases."<commentary>This request involves security, architecture, UI/UX, and implementation concerns that need coordinated management through the full development lifecycle.</commentary></example>

Use this agent when you need to perform comprehensive security analysis on code or applications. This includes: when you've written new code that handles sensitive data or user input, before deploying code to production, when updating dependencies or third-party libraries, after implementing authentication or authorization logic, when working with database queries or API integrations, or whenever you need to ensure your code follows security best practices and is free from vulnerabilities.

Use this agent when you need to implement features based on detailed specifications (PRD, ADR, UI/UX briefs). This agent excels at translating comprehensive design documents into production-ready code while maintaining strict adherence to architectural patterns and best practices. <example>\nContext: The user has a set of design documents and needs to implement a new feature.\nuser: "I have a PRD for a user profile feature, an ADR defining our microservices architecture, and UI/UX mockups. Please implement the profile management functionality."\nassistant: "I'll use the coder agent to implement this feature based on your specifications."\n<commentary>\nSince the user has detailed specifications that need to be translated into code, use the coder agent to ensure proper implementation following all design documents.\n</commentary>\n</example>\n<example>\nContext: The user needs to implement a feature with strict architectural requirements.\nuser: "Here's the specification for our new payment processing module. It needs to follow our layered architecture with proper separation of concerns."\nassistant: "Let me use the coder agent to implement this payment module according to your specifications and architectural requirements."\n<commentary>\nThe user has specifications that require careful adherence to architectural patterns, making this a perfect use case for the coder agent.\n</commentary>\n</example>
