opencode-plugin-apprise

OpenCode plugin for multi-service notifications via Apprise.

Features

• Multi-service support for 128+ notification services via Apprise.
• Automatic notifications when foreground sessions go idle, with a 30-second grace period (background tasks are excluded).
• Delayed notifications for Question tool prompts (30-second grace period).
• Notifications for permission requests with dual-mechanism reliability.

Prerequisites

• OpenCode
• Python 3.x
• Apprise (pip install apprise)

Quick Start

• Install the plugin by adding it to your opencode.json plugin array:

  "plugins": ["opencode-plugin-apprise"]
  

  Or use the CLI: opencode plugins add opencode-plugin-apprise

• Configure Apprise with your notification URLs in a default Apprise config file such as ~/.apprise, ~/.apprise.yml, or ~/.config/apprise/apprise.yml.

  Example:

  # ~/.config/apprise/apprise.yml
  urls:
    - slack://TokenA/TokenB/TokenC
    - discord://webhook_id/webhook_token
    - tgram://bottoken/ChatID
  

• Restart OpenCode — the plugin will automatically detect Apprise and use your configured services.

Configuration

The plugin relies on Apprise's default configuration file behavior.

Apprise Config File Locations

Apprise automatically looks for config files in these locations (in order):

• ~/.apprise
• ~/.apprise.yml
• ~/.config/apprise/apprise.yml

For complete configuration options, see: https://github.com/caronc/apprise#configuration-file

Environment Variables

Variable	Required	Description
OPENCODE_NOTIFY_TAG	No	Apprise tag for filtering which configured services receive notifications. When set, only services matching this tag in your Apprise config will be notified.

Behavior Defaults

Setting	Value
Idle notification delay	30 seconds
Deduplication TTL	5 minutes (max 100 entries)
Question notification delay	30 seconds
Apprise CLI timeout	30 seconds

Notification Triggers

Idle

Fires 30 seconds after a foreground session goes idle. If the session becomes active again within 30 seconds, the notification is cancelled. Only root sessions (no parent) are notified — background agent sessions are automatically excluded. Includes the last user request, agent response, and todo status.

Severity: info

📢 OpenCode Attention Required
📝 Request: Build a REST API
🤖 Response: I've created the Express server...
📋 Todo: ✅ 3 done | ▶️ 1 in_progress | ⚪ 2 pending

Question

Fires 30 seconds after the Question tool is invoked. If the user answers within 30 seconds, the notification is cancelled. This prevents spam for quick interactions.

Severity: warning

❓ OpenCode Question
❓ Question: Deploy to production?
Options:
  1. yes
  2. no
  3. cancel

Permission

Fires when a tool requires explicit user permission. Uses two mechanisms for reliability: the primary permission.ask hook and a fallback permission.updated event listener. Permissions are deduplicated by ID to prevent double notifications.

Severity: warning

🔐 OpenCode Permission Required
🔧 Tool: bash
⚡ Action: execute rm -rf node_modules

Supported Services

Apprise supports many services. Use these URL formats:

• Slack: slack://TokenA/TokenB/TokenC
• Discord: discord://webhook_id/webhook_token
• Telegram: tgram://bottoken/ChatID
• Email: mailto://user:[e-mail]

How It Works

Deduplication

Identical notifications are suppressed for 5 minutes. Duplicates are identified by a hash of the notification type, title, user request, and question text. The cache holds a maximum of 100 entries with LRU eviction.

Troubleshooting

• apprise CLI not found: Run pip install apprise to install the required dependency.
• No notifications received: Check your Apprise config file (~/.apprise, ~/.apprise.yml, or ~/.config/apprise/apprise.yml) and test with apprise -t test -b test.
• Notifications not reaching a specific service: Set OPENCODE_NOTIFY_TAG to match the tag assigned to that service in your Apprise config.
• Too many notifications: Deduplication suppresses identical notifications for 5 minutes.
• Apprise command hangs: The CLI timeout is 30 seconds. If Apprise doesn't respond in time, the notification fails silently.
