-# VibeTunnel OpenCode Configuration
-
-This file contains frequently used commands and project-specific information for VibeTunnel development.
-
-## Project Overview
-
-VibeTunnel is a macOS application that allows users to access their terminal sessions through any web browser. It consists of:
-- Native macOS app (Swift/SwiftUI) in `mac/`
-- iOS companion app in `ios/`
-- Web frontend (TypeScript/LitElement) and Node.js/Bun server in `web/`
-
-## Essential Commands
-
-### Web Development (in `web/` directory)
-
-```bash
-# Development
-pnpm run dev                   # Standalone development server (port 4020)
-pnpm run dev --port 4021       # Alternative port for external device testing
-
-# Code quality (MUST run before commit)
-pnpm run lint                  # Check for linting errors
-pnpm run lint:fix              # Auto-fix linting errors
-pnpm run format                # Format with Prettier
-pnpm run typecheck             # Check TypeScript types
-
-# Testing (only when requested)
-pnpm run test
-pnpm run test:coverage
-pnpm run test:e2e
-```
-
-### macOS Development (in `mac/` directory)

-
-### Project-wide Commands
-
-```bash
-# Run all tests with coverage
-./scripts/test-all-coverage.sh
-
-# Validate documentation
-./scripts/validate-docs.sh
-```
-
-## Development Workflow
-
-### Web Development Modes
-
-1. **Production Mode**: Mac app embeds pre-built web server
-   - Every web change requires: clean → build → run
-   - Simply restarting serves STALE, CACHED version
-
-2. **Development Mode** (recommended for web development):
-   - Enable "Use Development Server" in VibeTunnel Settings → Debug
-   - Mac app runs `pnpm run dev` instead of embedded server
-   - Provides hot reload - web changes automatically rebuild
-
-### Testing on External Devices
-
-```bash
-# Run dev server accessible from external devices
-cd web
-pnpm run dev --port 4021 --bind 0.0.0.0
-```
-
-Then access from external device using `http://[mac-ip]:4021`
-
-## Code Style Preferences
-
-- Use TypeScript for all new web code
-- Follow existing Swift conventions for macOS/iOS
-- Run linting and formatting before commits
-- Maintain test coverage (75% for macOS/iOS, 80% for web)
-
-## Architecture Notes
-
-### Key Entry Points
-- **Mac App**: `mac/VibeTunnel/VibeTunnelApp.swift`
-- **Web Frontend**: `web/src/client/app.ts`
-- **Server**: `web/src/server/server.ts`
-- **Server Management**: `mac/VibeTunnel/Core/Services/ServerManager.swift`
-
-### Terminal Sharing Protocol
-1. **Session Creation**: `POST /api/sessions` spawns new terminal
-2. **Input**: `POST /api/sessions/:id/input` sends keyboard/mouse input
-3. **Output**: SSE stream at `/api/sessions/:id/stream` (text) + WebSocket at `/buffers` (binary)
-4. **Resize**: `POST /api/sessions/:id/resize`
-
-## Important Rules
-
-1. **NEVER create new branches without explicit user permission**
-2. **NEVER commit/push before user has tested changes**
-3. **NEVER use `git rebase --skip`**
-4. **NEVER create duplicate files with version numbers**
-5. **NEVER kill all sessions** (you're running inside one)
-6. **NEVER rename docs.json to mint.json**
-
-## Useful File Locations

 # Push Notifications in VibeTunnel
 
-Push notifications in VibeTunnel allow you to receive real-time alerts about your terminal sessions, even when the web interface isn't active or visible. This keeps you informed about important events like completed commands, session exits, or system alerts.
+VibeTunnel provides real-time alerts for terminal events via native macOS notifications and web push notifications. The system is primarily driven by the **Session Monitor**, which tracks terminal activity and triggers alerts.
 
-## User Guide
+## How It Works
 
-1. **Enable Notifications**: Click the notification status indicator in the web interface (typically shows as red when disabled)
-2. **Grant Permission**: Your browser will prompt you to allow notifications - click "Allow"
-3. **Configure Settings**: Choose which types of notifications you want to receive
+The **Session Monitor** is the core of the notification system. It observes terminal sessions for key events and dispatches them to the appropriate notification service (macOS or web).
 
-VibeTunnel supports several types of notifications:
+### Key Monitored Events
+- **Session Start/Exit**: Get notified when a terminal session begins or ends.
+- **Command Completion**: Alerts for long-running commands.
+- **Errors**: Notifications for commands that fail.
+- **Terminal Bell**: Triggered by programs sending a bell character (`^G`).
+- **Claude "Your Turn"**: A special notification when Claude AI finishes a response and is awaiting your input.
 
-- **Bell Events**: Triggered when terminal programs send a bell character (e.g., when a command completes)
-- **Session Start**: Notified when a new terminal session begins
-- **Session Exit**: Alerted when a terminal session ends
-- **Session Errors**: Informed about session failures or errors
-- **System Alerts**: Receive server status and system-wide notifications
+## Native macOS Notifications
 
-Access notification settings by clicking the notification status indicator:
+The VibeTunnel macOS app provides the most reliable and feature-rich notification experience.
 
-- **Enable/Disable**: Toggle notifications on or off entirely
-- **Notification Types**: Choose which events trigger notifications (Session Exit and System Alerts are enabled by default)
-- **Behavior**: Control sound and vibration settings
-- **Test**: Send a test notification to verify everything works
+- **Enable**: Go to `VibeTunnel Settings > General` and toggle **Show Session Notifications**.
+- **Features**: Uses the native `UserNotifications` framework, respects Focus Modes, and works in the background.
 
-Note that just because you can configure something, does not mean your browser will support it.
+## Web Push Notifications
 
-## Push and Claude
+For non-macOS clients or remote access, VibeTunnel supports web push notifications.
 
-Claude code by default tries auto detection for terminal bells which can cause issues.  You can force it
-to emit a bell with this command:
-
-```
-claude config set --global preferredNotifChannel terminal_bell
-```
+- **Enable**: Click the notification icon in the web UI and grant browser permission.
+- **Technology**: Uses Service Workers and the Web Push API.
 
 ## Troubleshooting
 
-- **Not receiving notifications**: Check that notifications are enabled both in VibeTunnel settings and your browser permissions
-- **Too many notifications**: Adjust which notification types are enabled in the settings
-- **Missing notifications**: Ensure your browser supports Service Workers and the Push API (most modern browsers do)
+- **No Notifications**: Ensure they are enabled in both VibeTunnel settings and your OS/browser settings.
+- **Duplicate Notifications**: You can clear old or duplicate subscriptions by deleting `~/.vibetunnel/notifications/subscriptions.json`.
+- **Claude Notifications**: If Claude's "Your Turn" notifications aren't working, you can try forcing it to use the terminal bell:
+  ```bash
+  claude config set --global preferredNotifChannel terminal_bell
+  ```
 
-## Technical Implementation
-
-VibeTunnel's push notification system uses rather modern web standards:
-
-- **Web Push API**: For delivering notifications to browsers
-- **Service Workers**: Handle notifications when the app isn't active
-- **VAPID Protocol**: Secure authentication between server and browser
-- **Terminal Integration**: Smart detection of bell characters and session events
-
-### Bell Detection
-
-The system intelligently detects when terminal programs send bell characters (ASCII 7):
-
-- **Smart Filtering**: Ignores escape sequences that end with bell characters (not actual alerts)
-- **Process Context**: Identifies which program triggered the bell for meaningful notifications (best effort)
-
-## Subscription State
-
-VibeTunnel stores push notification data in the `~/.vibetunnel/` directory:
-
-```
-~/.vibetunnel/
-├── vapid/
-│   └── keys.json                     # VAPID public/private key pair
-└── notifications/
-    └── subscriptions.json            # Push notification subscriptions
-```
-
-**VAPID Keys** (`~/.vibetunnel/vapid/keys.json`):
-- Contains the public/private key pair used for VAPID authentication
-- File permissions are restricted to owner-only (0o600) for security
-- Keys are automatically generated on first run if not present
-- Used to authenticate push notifications with browser push services
-- Don't delete this or bad stuff happens to existing subscriptions.
-
-**Subscriptions** (`~/.vibetunnel/notifications/subscriptions.json`):
-- Stores active push notification subscriptions from browsers
-- Each subscription includes endpoint URL, encryption keys, and metadata
-- Automatically cleaned up when subscriptions become invalid or expired
-- Synchronized across all active sessions for the same user
-- If you get duplicated push notifications, you can try to delete old sessions here.
-
-The subscription data is persistent across application restarts and allows VibeTunnel to continue sending notifications even after the server restarts.
