modbender BullyBuddy
Spawns and manages multiple Claude Code CLI sessions. Dual backend: tmux (default, sessions survive server restart) or node-pty (fallback). REST API, WebSocket streaming, web dashboard.
Setup
- Install the package globally:
npm install -g openclaw-bullybuddy
- Start the server:
bullybuddy server
Connection info is auto-saved to ~/.bullybuddy/connection.json on startup. The /bullybuddy command reads it automatically — no env vars needed.
For remote access, start with bullybuddy server --tunnel. The tunnel URL is available via /bullybuddy url.
/bullybuddy Slash Command
/bullybuddy status - Server status & session summary
/bullybuddy list - List all sessions
/bullybuddy spawn [cwd] [task] [group] - Create new session
/bullybuddy send <id> <text> - Send input to session
/bullybuddy output <id> [lines] - Show session output/transcript
/bullybuddy kill <id> - Terminate session
/bullybuddy url - Show dashboard URL (local + tunnel)
/bullybuddy audit [limit] - View audit log
/bullybuddy transcript <id> [limit] - View conversation transcript
/bullybuddy help - Show help
Security Notice
- The auth token grants full control over all spawned Claude Code sessions, including sending arbitrary input. Treat it as a secret.
- The
/bullybuddy urlcommand outputs the dashboard URL with the token embedded. Do not share or log this URL publicly. - When using
--tunnel, the dashboard and API are exposed to the internet via a Cloudflare temporary URL. Anyone with the token can access all sessions remotely. - Spawned sessions run Claude Code with your local permissions. If
--dangerously-skip-permissionsis enabled, Claude can execute any command without confirmation.
Authentication
A random token is generated on each server start and saved to ~/.bullybuddy/connection.json (mode 0600). CLI and /bullybuddy auto-discover it. For the dashboard, the token is included in the URL printed on startup. The connection file is deleted on graceful shutdown.

All endpoints require the token via Authorization: Bearer <token> header or ?token= query parameter. All responses follow { ok: boolean, data?: T, error?: string }.

Spawn Request Body
{
"name": "worker-1",
"group": "myproject",
"cwd": "/path/to/repo",
"task": "Implement feature X",
"args": ["--verbose"],
"cols": 120,
"rows": 40,
"skipPermissions": false
}
All fields optional. When task is provided, it is automatically sent as input when Claude reaches the idle prompt.
Note: When sending input, terminate with \r (carriage return), not \n.
WebSocket Protocol
Connect to ws://<host>:<port>/ws?token=<token>.

State Detection
BullyBuddy analyzes raw PTY output to detect Claude Code's state in real-time.
detailedState |
Meaning |
|---|---|
starting |
Session just spawned, Claude loading |
working |
Claude is thinking/editing (spinner visible) |
permission_needed |
Claude waiting for user approval |
idle |
Claude at prompt, ready for input |
compacting |
Compacting conversation history |
error |
Error detected in output |
State transitions are broadcast via WebSocket and reflected in GET /api/summary.
OpenClaw Integration
Poll GET /api/summary on an interval to check fleet status. The sessionsNeedingAttention field contains IDs of sessions in permission_needed or error state.
Remote Access
Start the server with --tunnel to create a Cloudflare temporary URL automatically:
bullybuddy server --tunnel
The tunnel URL is printed on startup and saved to ~/.bullybuddy/connection.json. Use bullybuddy url or /bullybuddy url to retrieve it anytime.
CLI Commands
bullybuddy server # Start server
bullybuddy server --tunnel # Start with Cloudflare tunnel
bullybuddy url # Show dashboard URL (local + tunnel)
