### Default Gateway

- Bind: `127.0.0.1:18789` (loopback)
- Dashboard: `http://127.0.0.1:18789/`
- Protocol: WebSocket (JSON text frames)

## Core Workflow

### Diagnosing Issues

Always follow this command ladder:

1. `openclaw status` — quick overview
2. `openclaw gateway status` — daemon running? RPC probe ok?
3. `openclaw logs --follow` — watch for errors
4. `openclaw doctor` — config/service diagnostics
5. `openclaw channels status --probe` — per-channel health

### Starting / Restarting Gateway

```bash
# Foreground with verbose logging
openclaw gateway --port 18789 --verbose

# Force-kill existing listener then start
openclaw gateway --force

# Service management (launchd on macOS, systemd on Linux)
openclaw gateway install
openclaw gateway start
openclaw gateway stop
openclaw gateway restart
```

### Configuration

Edit config via any method:

```bash
# Interactive wizard
openclaw onboard                    # Full setup
openclaw configure                  # Config wizard

# CLI one-liners
openclaw config get <path>          # Read value
openclaw config set <path> <value>  # Set value (JSON5 or raw string)
openclaw config unset <path>        # Remove value

# Direct edit
# Edit ~/.openclaw/openclaw.json (JSON5 format)
# Gateway hot-reloads on save (if gateway.reload.mode != "off")
```

Minimal config example:

```json5
{
  agents: { defaults: { workspace: "~/.openclaw/workspace" } },
  channels: { whatsapp: { allowFrom: ["+15555550123"] } },
}
```

### Channel Setup

For detailed per-channel setup, see [references/channels.md](references/channels.md).
For per-channel troubleshooting (failure signatures, setup walkthroughs), see [references/channel_troubleshooting.md](references/channel_troubleshooting.md).
For plugins adding new channels (Matrix, Nostr, MS Teams, etc.), see [references/plugins.md](references/plugins.md).

Quick channel add:

```bash
# Interactive wizard
openclaw channels add

# Non-interactive
openclaw channels add --channel telegram --account default --name "My Bot" --token $BOT_TOKEN
openclaw channels login --channel whatsapp     # QR pairing for WhatsApp
openclaw channels status --probe               # Verify
```

### Model Provider Setup

For detailed provider setup, see [references/providers.md](references/providers.md).

```bash
# Set default model
openclaw models set anthropic/claude-sonnet-4-5

# List available models
openclaw models list --all

# Check auth/token status
openclaw models status --probe

# Add auth interactively
openclaw models auth add
```

Config example:

```json5
{
  agents: {
    defaults: {
      model: {
        primary: "anthropic/claude-sonnet-4-5",
        fallbacks: ["openai/gpt-5.2"],
      },
    },
  },
}
```

### Multi-Agent Routing

For detailed multi-agent config, see [references/multi_agent.md](references/multi_agent.md).

```bash
openclaw agents add <id>                # Create agent
openclaw agents list --bindings         # Show agent-channel bindings
openclaw agents delete <id>             # Remove agent
```

### Nodes (iOS / Android / macOS / Headless)

For detailed node setup, see [references/nodes.md](references/nodes.md).

```bash
openclaw nodes status                   # List connected nodes
openclaw nodes describe --node <id>     # Node capabilities
openclaw devices list                   # Pending device approvals
openclaw devices approve <requestId>    # Approve a device
openclaw node run --host <host> --port 18789  # Start headless node host
```

openclaw security audit --fix           # Auto-fix safe issues
openclaw secrets reload                 # Re-resolve secret refs
openclaw secrets audit                  # Scan for plaintext leaks
```

## Common Failure Signatures

| Error | Cause | Fix |
|---|---|---|
| `refusing to bind gateway ... without auth` | Non-loopback bind without token | Set `gateway.auth.token` or `gateway.auth.password` |
| `another gateway instance is already listening` / `EADDRINUSE` | Port conflict | `openclaw gateway --force` or change port |
| `Gateway start blocked: set gateway.mode=local` | Local mode not enabled | Set `gateway.mode="local"` |
| `unauthorized` / reconnect loop | Token/password mismatch | Check `OPENCLAW_GATEWAY_TOKEN` or config auth |
| `device identity required` | Missing device auth | Ensure client completes connect.challenge flow |
| No replies from bot | Pairing/allowlist/mention gating | Check `openclaw pairing list`, DM policy, mention patterns |
| `Embedding provider authentication failed (401)` | `.env` has placeholder API key (e.g. `your-jina-api-key-here`) | Replace with real API key in `~/.openclaw/.env`, restart Gateway |
| `config change requires gateway restart (plugins.*)` | Plugin config changes can't hot-reload | Full `openclaw gateway restart` or `launchctl kickstart -k` |
| `Bootstrap failed: 5: Input/output error` | LaunchAgent plist in stale/stuck state | `openclaw gateway install` then `launchctl kickstart -k gui/$(id -u)/ai.openclaw.gateway` |
| `Missing env var "X" referenced at config path: ...` | `.env` missing or variable not defined | Add variable to `~/.openclaw/.env` and restart Gateway |
