Native OS notifications for OpenCode V2

A CLI plugin for OpenCode V2 that delivers native OS notifications when tasks complete, errors occur, or the AI needs your input.

Why This Exists

You delegate a task and switch to another window. Now you're checking back every 30 seconds. Did it finish? Did it error? Is it waiting for permission?

This plugin solves that:

• Stay focused - Work in other apps. A notification arrives when the AI needs you.
• Uses OpenCode's built-in attention API - Native notifications on all platforms
• Smart defaults - Won't spam you. Only notifies for meaningful events with parent-session filtering and quiet-hours support.
• Lightweight - Event-driven, no tools added to your conversation

Installation

opencode plugin add @serkanalgur/opencodev2-notification

Via opencode.json

Add to your opencode.json or opencode.jsonc:

{
  "plugins": ["@serkanalgur/opencodev2-notification"]
}

As a local plugin

Or copy the plugin files to your .opencode/plugins/ directory:

.opencode/plugins/notification/index.ts

How It Works

"Notify the human when the AI needs them back, not for every micro-event."

Event	Notifies?	Sound	Why
Session complete	Yes	Glass	Main task done - time to review
Session error	Yes	Basso	Something broke - needs attention
Permission needed	Yes	Submarine	AI is blocked, waiting for you
Question asked	Yes	Submarine (default)	Questions should always reach you promptly
Sub-task complete/error	No (default)	-	Set notifyChildSessions: true to include child sessions

The plugin automatically:

• Uses OpenCode's built-in attention.notify() API for native notifications
• Only notifies when terminal is not focused (no spam while you're working)
• Deduplicates rapid-fire notifications

FAQ

Does this add bloat to my context?

Minimal footprint. The plugin is event-driven - it listens for session events and fires notifications. No tools are added to your conversation.

Will I get spammed with notifications?

No. Smart defaults prevent noise:

• Only notifies for parent sessions (not every sub-task)
• Supports quiet-hours suppression
• Only notifies when terminal is not focused
• Deduplication prevents rapid-fire notifications

Can I disable it temporarily?

Remove the plugin from your opencode.json or delete the plugin files.
