# OneSignal Management Skill

Manage and analyze OneSignal push notification resources including notifications, segments, and delivery metrics.

## API Conventions

### Authentication
All API calls use REST API key and App ID, injected automatically.

### Base URL
`https://onesignal.com/api/v1`

### Core Helper Function

```bash
#!/bin/bash

onesignal_api() {
    local method="$1"
    local endpoint="$2"
    local data="${3:-}"

    if [ -n "$data" ]; then
        curl -s -X "$method" \
            -H "Authorization: Basic $ONESIGNAL_REST_API_KEY" \
            -H "Content-Type: application/json" \
            "https://onesignal.com/api/v1${endpoint}" \
            -d "$data"
    else
        curl -s -X "$method" \
            -H "Authorization: Basic $ONESIGNAL_REST_API_KEY" \
            "https://onesignal.com/api/v1${endpoint}"
    fi
}
```

## Output Rules
- Target ≤50 lines per script output
- Use `jq` to extract only needed fields
- Never dump full API responses

## Phase 1: Discovery

```bash
#!/bin/bash
echo "=== App Info ==="
onesignal_api GET "/apps/$ONESIGNAL_APP_ID" \
    | jq '{name: .name, players: .players, messageable_players: .messageable_players, gcm_key_set: (.gcm_key != null), apns_configured: (.apns_certificates != null)}'

echo ""
echo "=== Recent Notifications ==="
onesignal_api GET "/notifications?app_id=$ONESIGNAL_APP_ID&limit=20" \
    | jq -r '.notifications[] | "\(.id[0:12])\t\(.successful)\tconv:\(.converted // 0)\t\(.headings.en[0:30] // "no-title")\t\(.completed_at // "pending")"' \
    | column -t | head -20

echo ""
echo "=== Segments ==="
onesignal_api GET "/apps/$ONESIGNAL_APP_ID/segments" \
    | jq -r '.segments[] | "\(.id[0:16])\t\(.name)\t\(.is_active)"' | head -15
```

## Phase 2: Analysis

### Delivery Analytics

```bash
#!/bin/bash
echo "=== Notification Delivery Summary (recent 50) ==="
onesignal_api GET "/notifications?app_id=$ONESIGNAL_APP_ID&limit=50" \
    | jq '{
        total_sent: [.notifications[].successful // 0] | add,
        total_failed: [.notifications[].failed // 0] | add,
        total_converted: [.notifications[].converted // 0] | add,
        avg_delivery_rate: ([.notifications[] | select(.successful != null and .remaining == 0) | (.successful / ((.successful + .failed) // 1) * 100)] | if length > 0 then add / length | floor else 0 end)
    }'

echo ""
echo "=== Failed Notifications ==="
onesignal_api GET "/notifications?app_id=$ONESIGNAL_APP_ID&limit=50" \
    | jq -r '.notifications[] | select(.failed > 0) | "\(.id[0:12])\tsent:\(.successful)\tfailed:\(.failed)\t\(.headings.en[0:30] // "no-title")"' \
    | head -10

echo ""
echo "=== Platform Breakdown ==="
onesignal_api GET "/notifications?app_id=$ONESIGNAL_APP_ID&limit=20" \
    | jq -r '.notifications[0] | .platform_delivery_stats // "N/A"'
```

### User Engagement

```bash
#!/bin/bash
echo "=== Subscriber Summary ==="
onesignal_api GET "/apps/$ONESIGNAL_APP_ID" \
    | jq '{total_players: .players, messageable: .messageable_players, unsubscribed: (.players - .messageable_players)}'

echo ""
echo "=== Top Performing Notifications (by conversion) ==="
onesignal_api GET "/notifications?app_id=$ONESIGNAL_APP_ID&limit=50" \
    | jq -r '.notifications[] | select(.converted > 0) | "\(.converted)\t\(.successful)\t\(.headings.en[0:40] // "no-title")"' \
    | sort -rn | head -10
```

## Output Format

```
=== App: <name> ===
Subscribers: <n>  Messageable: <n>

--- Delivery (recent) ---
Sent: <n>  Failed: <n>  Converted: <n>
Avg Delivery Rate: <n>%

--- Segments ---
Total: <n>  Active: <n>
```

## Anti-Hallucination Rules

1. **NEVER assume resource names** — always discover via CLI/API in Phase 1 before referencing in Phase 2.
2. **NEVER fabricate metric names or dimensions** — verify against the service documentation or `--help` output.
3. **NEVER mix CLI commands between service versions** — confirm which version/API you are targeting.
4. **ALWAYS use the discovery → verify → analyze chain** — every resource referenced must have been discovered first.
5. **ALWAYS handle empty results gracefully** — an empty response is valid data, not an error to retry.

## Counter-Rationalizations

| Shortcut | Counter | Why |
|----------|---------|-----|
| "I'll skip discovery and check known resources" | Always run Phase 1 discovery first | Resource names change, new resources appear — assumed names cause errors |
| "The user only asked for a quick check" | Follow the full discovery → analysis flow | Quick checks miss critical issues; structured analysis catches silent failures |
| "Default configuration is probably fine" | Audit configuration explicitly | Defaults often leave logging, security, and optimization features disabled |
| "Metrics aren't needed for this" | Always check relevant metrics when available | API/CLI responses show current state; metrics reveal trends and intermittent issues |
| "I don't have access to that" | Try the command and report the actual error | Assumed permission failures prevent useful investigation; actual errors are informative |

## Common Pitfalls
- **App ID required**: Most endpoints need `app_id` as query parameter
- **Two auth keys**: REST API Key for most endpoints, User Auth Key for app management
- **Rate limits**: 1 request/second for notification creation, higher for reads
- **Pagination**: Use `limit` and `offset`; max limit is 50 for notifications
