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.
