zeenie-ai Process Manager Tool
Manage long-running processes with full system PATH access. Use this for anything that needs npm, python, node, or runs as a persistent server/watcher.
Security
The process manager blocks destructive file commands to prevent accidental deletion outside the agent's workspace. Use shell_execute for file operations instead (sandboxed, no PATH, confined to workspace).
Blocked commands: rm, rmdir, del, rd, Remove-Item, format, mkfs, dd, shred, chmod 777
Allowed: npm, python, node, pip, cargo, go, servers, build tools, installers
Operations
start
Launch a process. Output streams to the Terminal tab and is saved to log files.
{"operation": "start", "name": "dev-server", "command": "python -m http.server 8080"}
stop
Kill a process and its entire process tree.
{"operation": "stop", "name": "dev-server"}
restart
Stop then re-launch with the same command.
{"operation": "restart", "name": "dev-server"}
list
Show all running processes for this workflow.
{"operation": "list"}
get_output
Read output from a process's log file. Use tail to get last N lines, stream to choose stdout or stderr.
{"operation": "get_output", "name": "dev-server", "stream": "stdout", "tail": 20}
Returns {"lines": [...], "total": 150, "file": "/path/to/stdout.log"}.
send_input
Write text to a process's stdin (newline appended automatically).
{"operation": "send_input", "name": "dev-server", "text": "quit"}
Shell vs Process Manager
| Need | Tool | Why |
|---|---|---|
ls, cat, find, grep |
shell_execute | Sandboxed, fast, no PATH |
rm, mv, cp, file ops |
shell_execute | Sandboxed, confined to workspace |
npm install, pip install |
process_manager | Needs PATH |
python script.py |
process_manager | Needs PATH |
npm run dev, flask run |
process_manager | Long-running, streams output |
| Dev servers, watchers | process_manager | Persistent, log files |
Output Log Files
Each process writes to its own log files in the agent's workspace:
{workspace}/{agent_node_id}/.processes/{process_name}/
stdout.log # Standard output
stderr.log # Error output
Use get_output to read them selectively. The agent can also read these files directly with the file_read tool.
OS-Specific Commands
Commands differ by platform. Refer to:
- bash-skill -- Linux/macOS (apt, brew, lsof, kill, curl)
- powershell-skill -- Windows (Get-Process, Stop-Process, Invoke-WebRequest)
- wsl-skill -- Running Linux tools on Windows (prefix with
wsl)
Detect the OS first:
{"operation": "start", "name": "os", "command": "python -c \"import platform; print(platform.system())\""}
Returns Windows, Linux, or Darwin (macOS).
Guidelines
- Always give processes a meaningful name so you can stop/check them later
- Use get_output after starting to verify the process launched correctly
- Use stop to clean up processes when done -- don't leave servers running
- Do NOT use process_manager for file deletion -- use shell_execute instead
- Processes are automatically killed when the server shuts down
- Max concurrent processes: configurable in Settings (default: 10)
- Output streams to the Terminal tab in real-time
