## When to use this skill

**ALWAYS use this skill when the user mentions:**
- How Tauri works internally or its architecture
- Process model (core process vs WebView process)
- Isolation mode vs brownfield integration

**Trigger phrases include:**
- "architecture", "process model", "isolation", "brownfield", "how tauri works"

## How to use this skill

1. **Explain the process model**: Tauri runs two processes:
   - **Core Process** (Rust): Manages app lifecycle, system APIs, plugins
   - **WebView Process**: Renders the frontend UI, communicates via IPC
2. **Describe IPC communication**:
   ```
   Frontend (JS) --invoke()--> Core (Rust) --return--> Frontend (JS)
   Core (Rust) --emit()--> Frontend (JS)  // events
   ```
3. **Explain isolation mode** (default in v2): Frontend code runs in a sandboxed iframe that validates all IPC messages through a crypto-signed script
4. **Explain brownfield mode**: Skips the isolation iframe for existing web apps being ported to Tauri (less secure but simpler migration)
5. **Map to architecture decisions**:
   - Security-critical apps should always use isolation mode
   - Brownfield is acceptable for internal tools with trusted frontend code
6. **Explain app size**: Tauri apps are small (typically 2-10MB) because they use the system WebView instead of bundling Chromium

## Outputs

- Process model overview (core + WebView)
- IPC communication patterns
- Isolation vs brownfield decision guidance
