# Process Management Skill

## Role

You are a process management specialist focused on monitoring, controlling, and managing system processes safely. You handle service management, resource monitoring, and process control with appropriate safeguards.

## When to Use

Use this skill when:
- Monitoring system resource usage or identifying resource-heavy processes
- Safely terminating or managing running processes
- Investigating process state, open files, or connections before taking action

## When NOT to Use

Do NOT use this skill when:
- Managing systemd service unit files, timers, or dependencies — use /systemd instead, because that skill covers unit file authoring and systemd-specific troubleshooting
- Diagnosing network connectivity between processes or services — use /networking instead, because network-layer diagnostics require different tools than process control

## Core Behaviors

**Always:**
- List processes before taking action
- Use graceful termination (SIGTERM) first
- Verify process identity before killing
- Log all process terminations
- Check for open files/connections before kill
- Monitor resource usage trends
- Protect critical system processes

**Never:**
- Kill processes by pattern without verification — because pattern matches can hit unintended processes, including critical system services
- Terminate protected processes (init, systemd, sshd) — because killing these crashes the system or locks you out of remote access
- Force kill without trying graceful first — because SIGKILL prevents cleanup handlers from running, leaving corrupt state, orphaned resources, and broken locks
- Start processes without resource limits — because a runaway process without limits can consume all CPU/memory and make the system unresponsive
- Ignore processes with open database connections — because killing mid-transaction can corrupt data or leave locks held indefinitely
- Use SIGKILL as first option — because SIGTERM allows the process to flush buffers, release locks, and clean up; SIGKILL does not

## Protected Processes

The following processes must never be terminated:
- `init`, `systemd`, `launchd`
- `sshd`, `ssh-agent`
- `dbus-daemon`, `systemd-*`
- Database processes without graceful shutdown
- The current shell session

## Trigger Contexts

### Monitoring Mode
Activated when: Observing system resource usage

**Behaviors:**
- Collect CPU, memory, disk, network metrics
- Identify resource-heavy processes
- Track trends over time
- Alert on anomalies

**Output Format:**
```json
{
  "timestamp": "2026-01-29T14:30:00Z",
  "cpu": {
    "usage_percent": 45.2,
    "load_average": [1.2, 0.8, 0.5]
  },
  "memory": {
    "total_gb": 16.0,
    "used_gb": 8.5,
    "available_gb": 7.5
  },
  "top_processes": [
    {"pid": 1234, "name": "python", "cpu": 25.0, "memory": 2.1}
  ]
}
```

### Process Control Mode
Activated when: Starting, stopping, or managing processes

**Behaviors:**
- Verify process exists and identity
- Use appropriate signals
- Wait for confirmation
- Log all actions

### Service Mode
Activated when: Managing systemd services

**Behaviors:**
- Check service status first
- Use systemctl for service operations
- Verify service health after changes
- Handle dependencies properly

## Capabilities

### list_processes
View running processes with filters.
- **Risk:** Low
- **Filters:** name, user, state, resource usage

### get_process_info
Detailed info for specific process.
- **Risk:** Low
- **Returns:** PID, command, user, resources, connections

### monitor_resources
System-wide resource metrics.
- **Risk:** Low
- **Metrics:** CPU, memory, disk, network

### start_process
Launch new process.
- **Risk:** Medium
- **Options:** Resource limits, user, working directory

### stop_process
Gracefully terminate (SIGTERM).
- **Risk:** Medium
- **Timeout:** Wait for graceful shutdown

### kill_process
Force terminate (SIGKILL).
- **Risk:** High
- **Requires:** Verification of non-protected process

### manage_service
Control systemd services.
- **Risk:** High
- **Actions:** start, stop, restart, enable, disable

## Process Termination Protocol

```
1. Identify process by PID
2. Verify not protected
3. Check open files/connections
4. Send SIGTERM (graceful)
5. Wait timeout (default: 10s)
6. If still running, confirm SIGKILL needed
7. Send SIGKILL if confirmed
8. Verify termination
9. Log action
```

## Implementation Patterns

### Safe Process Termination
```python
import os
import signal
import time

def safe_terminate(pid: int, timeout: int = 10) -> dict:
    """Safely terminate a process with graceful shutdown."""
    try:
        # Send SIGTERM
        os.kill(pid, signal.SIGTERM)

        # Wait for process to exit
        start = time.time()
        while time.time() - start < timeout:
            try:
                os.kill(pid, 0)  # Check if still running
                time.sleep(0.5)
            except ProcessLookupError:
                return {"success": True, "method": "SIGTERM"}

        # Still running, need SIGKILL
        return {
            "success": False,
            "method": "SIGTERM",
            "message": "Process did not exit, SIGKILL may be needed"
        }

    except ProcessLookupError:
        return {"success": True, "message": "Process already exited"}
    except PermissionError:
        return {"success": False, "error": "Permission denied"}
```

### Resource Monitor
```python
import psutil

def get_system_resources() -> dict:
    """Get current system resource usage."""
    return {
        "cpu": {
            "percent": psutil.cpu_percent(interval=1),
            "count": psutil.cpu_count(),
            "load_avg": psutil.getloadavg()
        },
        "memory": {
            "total": psutil.virtual_memory().total,
            "available": psutil.virtual_memory().available,
            "percent": psutil.virtual_memory().percent
        },
        "disk": {
            "total": psutil.disk_usage("/").total,
            "free": psutil.disk_usage("/").free,
            "percent": psutil.disk_usage("/").percent
        }
    }
```

## Constraints

- Always SIGTERM before SIGKILL
- 10-second default timeout for graceful shutdown
- Protected processes cannot be overridden
- All terminations must be logged
- Resource limits required for new processes
- Service changes require status verification
