Use this agent when you need to evaluate, improve, or ensure accessibility compliance in UI components, web pages, or applications. This includes reviewing existing code for accessibility issues, providing guidance on implementing WCAG AA standards, auditing component libraries, or when building new features that need to be accessible to users with disabilities. Examples: <example>Context: User has just implemented a custom dropdown component and wants to ensure it meets accessibility standards. user: 'I just created this dropdown component, can you review it for accessibility?' assistant: 'I'll use the a11y-expert agent to review your dropdown component for WCAG AA compliance and provide specific recommendations.' <commentary>Since the user is asking for accessibility review of a component, use the a11y-expert agent to evaluate WCAG compliance.</commentary></example> <example>Context: User is planning to build a form and wants proactive accessibility guidance. user: 'I'm about to build a complex multi-step form. What accessibility considerations should I keep in mind?' assistant: 'Let me use the a11y-expert agent to provide comprehensive accessibility guidance for your multi-step form implementation.' <commentary>The user needs proactive accessibility guidance, so use the a11y-expert agent to provide WCAG-compliant recommendations.</commentary></example>

Use this agent when you need to define API contracts between frontend and backend teams. This includes creating clear specifications for endpoints, HTTP methods, request/response parameters, and example payloads. The agent should be used early in the development process before implementation begins, when planning new features that require API integration, or when documenting existing APIs for team alignment. Examples: <example>Context: The user needs to define API contracts for a new user authentication feature. user: "We need to create API contracts for our new authentication system including login, logout, and password reset" assistant: "I'll use the api-contract-architect agent to create comprehensive API contracts for the authentication system" <commentary>Since the user needs API contract documentation between frontend and backend teams, use the api-contract-architect agent to create clear specifications.</commentary></example> <example>Context: The user is planning a new feature and needs API specifications. user: "Let's define the API endpoints for the shopping cart feature" assistant: "I'm going to use the Task tool to launch the api-contract-architect agent to create the API contracts for the shopping cart feature" <commentary>The user needs API contract definitions for a new feature, so the api-contract-architect agent should be used.</commentary></example>

Use this agent when you need to build backend services using Node.js (NestJS), MySQL, and REST APIs. This includes creating API routes, implementing authentication, setting up error handling, defining database schemas, creating ER diagrams, and generating OpenAPI specifications. Examples: <example>Context: User needs to build a user management system backend. user: 'I need to create a user registration and login system with JWT authentication' assistant: 'I'll use the api-engineer agent to build the complete backend system with NestJS, MySQL schema, and authentication endpoints' <commentary>Since the user needs backend API development with the specified stack, use the api-engineer agent to handle the complete implementation.</commentary></example> <example>Context: User is building an e-commerce platform and needs product management APIs. user: 'Create REST endpoints for managing products - CRUD operations with categories and inventory tracking' assistant: 'Let me use the api-engineer agent to design the database schema and implement the product management API endpoints' <commentary>This requires backend API development with database design, perfect for the api-engineer agent.</commentary></example>

Use this agent when you need to review code output from any engineering agent to ensure quality, identify issues, and suggest improvements. Examples: After generating a new React component, use this agent to review the code for best practices and potential issues. When an API engineer creates new endpoints, use this agent to check for security vulnerabilities and performance concerns. After a mobile engineer implements a feature, use this agent to verify the code follows platform-specific guidelines and doesn't contain anti-patterns.
