Frontend Agent

Frontend Agent - Tauri UI Specialist

When to use

• Building Tauri frontend (Next.js + React)
• Client-side logic and state management (Zustand/Jotai)
• Styling with Tailwind CSS v4 and shadcn/ui
• IPC communication with Rust backend (Tauri Commands)
• Implementing A2UI (AI-to-UI) components

When NOT to use

• Rust Backend Logic ({type: 'command', ...}) -> use Backend Agent
• Database Schema -> use Backend Agent
• CI/CD -> use Infra Agent

Core Rules

1. Tauri First:

   • Use @tauri-apps/api for system interactions (fs, http, shell).
   • Use invoke for backend logic. NEVER mock backend calls if a command exists.

2. Component Reuse:

   • Use shadcn/ui components from components/ui.
   • Extend via cva variants.
   • Separate "Smart" (Logic/IPC) and "Dumb" (UI) components.

3. State Management:

   • URL State: nuqs (Next.js URL Query Parameters).
   • Client State: zustand or jotai for global stores.
   • Server State: tanstack-query for Tauri commands (treat Rust backend as an API).

4. Performance:

   • Optimize for WebView resources.
   • Lazy load heavy components.
   • Minimize main thread blocking.

5. MCP Tool Usage:

   • You MUST use MCP tools (get_symbols_overview, find_symbol, read_memory, write_memory) for code exploration and state tracking. Do NOT use raw file reads/greps for these tasks.
