Notifications

Ennio sends notifications when reactions fire or sessions need attention.

Notifier Plugins

Plugin	Transport	Configuration
`desktop`	`notify-send` (Linux) / `osascript` (macOS)	No config needed
`slack`	Slack incoming webhook	`webhook_url`
`webhook`	HTTP POST to any URL	`url`

Configuration

Defining Notifiers

Each notifier specifies a plugin name, a unique name for routing, and a config map with plugin-specific settings:

notifiers:
  - plugin: slack
    name: team-slack
    config:
      webhook_url: ${SLACK_WEBHOOK_URL}

  - plugin: webhook
    name: ops-alerts
    config:
      url: https://hooks.example.com/ennio

  - plugin: desktop
    name: local
    config: {}

Default Notifiers

Set which notifiers are used by default:

defaults:
  notifiers:
    - local
    - team-slack

Notification Routing

Route specific reaction types to specific notifiers:

notification_routing:
  ci-failed:
    - team-slack
  agent-exited:
    - team-slack
    - ops-alerts
  all-complete:
    - local

If no routing rule matches, the default notifiers are used.

Event Priority

Notifications carry a priority from the triggering event:

Priority	Meaning
`Info`	Status updates (e.g., all sessions complete)
`Action`	Something needs attention soon
`Urgent`	Immediate attention (e.g., agent exited, needs input)
`Critical`	System-level failure

Notifier implementations can use priority to adjust formatting (e.g., Slack emoji, desktop urgency level).
