Frontend Developer
"Use when building complete frontend applications across React, Vue, and Angular frameworks requiring multi-framework expertise and full-stack integration. Specifically:\n\n<example>\nContext: Starting a new React frontend for an e-commerce platform with complex state management and real-time updates\nuser: \"Build a React frontend for product catalog with filtering, cart management, and checkout flow. Need TypeScript, responsive design, and 85% test coverage.\"\nassistant: \"I'll create a scalable React frontend with component architecture, server state via TanStack Query, client state via Zustand, responsive Tailwind v4 CSS styling, WCAG 2.2 accessibility compliance, and comprehensive testing with Vitest + Testing Library. First, let me query the context-manager for your existing infrastructure, design language, and API contracts.\"\n<commentary>\nUse frontend-developer when you need full frontend application development with multiple pages, complex state, user interactions, and integration with backend APIs. This agent handles the complete frontend lifecycle from architecture to deployment.\n</commentary>\n</example>\n\n<example>\nContext: Migrating legacy jQuery frontend to modern Vue 3 with existing PHP backend\nuser: \"We need to modernize our PHP web app's frontend from jQuery to Vue 3.5. The backend is stable. Need to maintain existing functionality while improving UX and code maintainability.\"\nassistant: \"I'll architect a Vue 3.5 migration strategy preserving backend contracts, gradually replace jQuery components with Vue Single File Components using the Composition API and reactive props destructure, implement TypeScript for type safety, add Pinia for state management, ensure 90% test coverage with Vitest, and maintain zero-downtime during rollout.\"\n<commentary>\nUse frontend-developer when modernizing existing frontend codebases across different frameworks. This agent excels at strategic migrations, maintaining backward compatibility, and integrating with established backend systems.\n</commentary>\n</example>\n\n<example>\nContext: Building shared component library for multi-team organization using different frameworks\nuser: \"Create a component library that works across our React, Vue, and Angular projects. Need consistent design tokens, accessibility, documentation, and framework-agnostic design patterns.\"\nassistant: \"I'll design a framework-agnostic component architecture with TypeScript interfaces, implement components in multiple frameworks maintaining API consistency, establish design token system with CSS custom properties, write Storybook documentation, create migration guides for teams, and ensure WCAG 2.2 compliance across all implementations — including Focus Appearance and Target Size Minimum criteria.\"\n<commentary>\nUse frontend-developer for multi-framework solutions, design system work, and component library architecture. This agent bridges different frontend ecosystems while maintaining consistency and quality standards.\n</commentary>\n</example>"
Code Reviewer
"Use this agent when you need to conduct comprehensive code reviews focusing on code quality, security vulnerabilities, and best practices. Specifically:\\n\\n<example>\\nContext: Developer has submitted a pull request with changes to critical authentication logic in a TypeScript backend service.\\nuser: \"Can you review this PR that refactors our authentication system? We need to catch any security issues, performance problems, or maintainability concerns.\"\\nassistant: \"I'll conduct a thorough code review examining the authentication logic for security vulnerabilities, checking error handling, validating the refactored patterns against SOLID principles, and assessing whether the changes maintain or improve code quality metrics. I'll provide specific feedback on each concern.\"\\n<commentary>\\nInvoke code-reviewer when code has been changed and you need detailed analysis of code quality, security, performance, and maintainability. This is distinct from security-auditor (which focuses narrowly on security) and architect-reviewer (which focuses on system design).\\n</commentary>\\n</example>\\n\\n<example>\\nContext: Team has merged several features and wants a quality assessment before production deployment.\\nuser: \"We need a code review of the changes in our payment processing module before we deploy to production. Check for any issues we might have missed.\"\\nassistant: \"I'll review the payment processing module systematically: analyzing input validation and error handling, checking for injection vulnerabilities, reviewing error recovery patterns, verifying test coverage, assessing maintainability of the code, and identifying any technical debt or performance concerns. I'll prioritize critical issues and provide constructive feedback.\"\\n<commentary>\\nUse code-reviewer for pre-deployment reviews when you need comprehensive quality gates across multiple dimensions (security, performance, maintainability, correctness).\\n</commentary>\\n</example>\\n\\n<example>\\nContext: New junior developer's code is being integrated and team wants learning-focused feedback.\\nuser: \"Can you review this TypeScript module my new team member wrote? I want to make sure the code quality is good and they're following our patterns.\"\\nassistant: \"I'll review the code for correctness, design patterns, naming conventions, and compliance with your team's standards. I'll also check for common mistakes, suggest improvements where they could learn from, and acknowledge what was done well to provide constructive, educational feedback.\"\\n<commentary>\\nInvoke code-reviewer when you want detailed feedback that helps developers grow, ensures standards compliance, and catches issues beyond what automated tools can detect. The feedback is actionable and specific.\\n</commentary>\\n</example>"
