pi-notifier

Windows desktop notifications for Pi. Get notified when the agent finishes, when API errors occur, or when tools fail.

Features

• Agent Finished - Know when Pi is ready for your next input
• Provider Error - Instant alerts for HTTP 4xx/5xx errors (rate limits, auth failures, etc.)
• Tool Error - Get notified when any tool execution fails
• Focus Detection - Notifications are suppressed when Pi's terminal is already focused (no redundant popups)
• Custom Sounds - Choose from 13 Windows system sounds or disable sounds per notification type
• Dark/Light Theme - Stylish toast popups with a modern look

Install

pi install npm:@steven-rothwell/pi-notifier

Configure

Run the /notifier command in Pi's TUI to:

• Toggle notifications on/off per type
• Change notification sounds
• Switch between dark and light themes
• Test notifications before enabling

/notifier

Requirements

• Windows - Uses PowerShell and WinForms for native notifications
• Pi - Requires @earendil-works/pi-coding-agent and @earendil-works/pi-tui

Configuration File

Settings are stored in ~/.pi/notifier.json. You can edit this file directly:

{
  "theme": "dark",
  "notifications": {
    "agentFinished": {
      "enabled": true,
      "sound": "C:\\Windows\\Media\\Windows Notify Messaging.wav"
    },
    "providerError": {
      "enabled": true,
      "sound": "C:\\Windows\\Media\\Windows Error.wav"
    },
    "toolError": {
      "enabled": true,
      "sound": "C:\\Windows\\Media\\Windows Exclamation.wav"
    }
  }
}

How It Works

Pi-notifier hooks into three Pi events:

1. agent_end - Fires when the agent finishes processing and is waiting for input
2. after_provider_response - Fires on HTTP 4xx/5xx responses from AI providers
3. tool_execution_end - Fires when any tool execution fails (isError: true)

Before showing a notification, it checks if Pi's terminal is the foreground window. If it is, the notification is skipped since you're already looking at Pi.
