# Sendbird Management Skill

Manage and analyze Sendbird messaging resources including channels, users, messages, and moderation.

## API Conventions

### Authentication
All API calls use API token in header, injected automatically.

### Base URL
`https://api-{app_id}.sendbird.com/v3`

### Core Helper Function

```bash
#!/bin/bash

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

    if [ -n "$data" ]; then
        curl -s -X "$method" \
            -H "Api-Token: $SENDBIRD_API_TOKEN" \
            -H "Content-Type: application/json" \
            "https://api-${SENDBIRD_APP_ID}.sendbird.com/v3${endpoint}" \
            -d "$data"
    else
        curl -s -X "$method" \
            -H "Api-Token: $SENDBIRD_API_TOKEN" \
            "https://api-${SENDBIRD_APP_ID}.sendbird.com/v3${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 "=== Group Channels ==="
sendbird_api GET "/group_channels?limit=20&order=latest_last_message" \
    | jq -r '.channels[] | "\(.channel_url[0:20])\t\(.name[0:30])\t\(.member_count) members\t\(.last_message.created_at // 0 | . / 1000 | strftime("%Y-%m-%d"))"' \
    | column -t | head -20

echo ""
echo "=== Open Channels ==="
sendbird_api GET "/open_channels?limit=20" \
    | jq -r '.channels[] | "\(.channel_url[0:20])\t\(.name[0:30])\t\(.participant_count) participants"' \
    | head -15

echo ""
echo "=== Users (recent) ==="
sendbird_api GET "/users?limit=20&order=latest_login" \
    | jq -r '.users[] | "\(.user_id[0:20])\t\(.nickname[0:20])\t\(.is_online)\t\(.last_seen_at | . / 1000 | strftime("%Y-%m-%d") // "never")"' \
    | column -t | head -15
```

## Phase 2: Analysis

### Channel Health

```bash
#!/bin/bash
echo "=== Channel Summary ==="
sendbird_api GET "/group_channels?limit=100" \
    | jq '{
        total_channels: (.channels | length),
        total_members: (.channels | map(.member_count) | add),
        avg_members: (.channels | map(.member_count) | if length > 0 then add / length | floor else 0 end),
        frozen_channels: [.channels[] | select(.freeze == true)] | length
    }'

echo ""
echo "=== Channels with Unread Messages ==="
sendbird_api GET "/group_channels?limit=20&unread_filter=unread_message" \
    | jq -r '.channels[] | "\(.channel_url[0:20])\t\(.name[0:25])\tunread:\(.unread_message_count)"' \
    | head -15

echo ""
echo "=== Empty Channels (0 members) ==="
sendbird_api GET "/group_channels?limit=20&members_exactly_in=&member_state_filter=joined_only" \
    | jq -r '.channels[] | select(.member_count <= 1) | "\(.channel_url[0:20])\t\(.name[0:25])\t\(.member_count) members"' \
    | head -10
```

### User & Moderation

```bash
#!/bin/bash
echo "=== Online Users ==="
sendbird_api GET "/users?limit=50&active_mode=activated&show_bot=false" \
    | jq '{
        total_returned: (.users | length),
        online: [.users[] | select(.is_online == true)] | length,
        offline: [.users[] | select(.is_online == false)] | length
    }'

echo ""
echo "=== Banned Users ==="
sendbird_api GET "/users?limit=20&user_ids_filter=" \
    | jq -r '[.users[] | select(.is_blocked == true)] | length | "Blocked users: \(.)"'

echo ""
echo "=== Moderation: Reported Messages ==="
sendbird_api GET "/report/messages?limit=20" \
    | jq -r '.report_logs[] | "\(.report_type)\t\(.reporting_user.user_id[0:16])\t\(.message.message[0:40])\t\(.created_at | . / 1000 | strftime("%Y-%m-%d"))"' \
    | head -10
```

## Output Format

```
=== Sendbird App: <app_id> ===

--- Channels ---
Group: <n>  Open: <n>  Frozen: <n>
Avg Members: <n>

--- Users ---
Total: <n>  Online: <n>  Blocked: <n>

--- Moderation ---
Reports: <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
- **Timestamps**: Sendbird uses Unix milliseconds, not seconds
- **Pagination**: Use `limit` and `token` (next page cursor); max 100 per request
- **Channel URL**: Channel URLs are unique identifiers; URL-encode special characters
- **Rate limits**: Varies by plan; check `X-RateLimit-*` response headers
- **App ID in URL**: Base URL includes the app ID as subdomain
