Workflow: Process Investigation

Phase 1: Discovery

Step 1.1: List Processes

Use process_list with:
- sort: "cpu" or "memory"
- limit: 20

Step 1.2: Find Specific Process

Use process_find with:
- name: Process name pattern
- user: Specific user (optional)

Phase 2: Analysis

Step 2.1: Process Tree

Use process_tree to see parent/child relationships

Step 2.2: Resource Usage

Use process_limits to check:
- Max open files
- Max processes
- Memory limits

Phase 3: Port Investigation

Step 3.1: Find by Port

Use process_ports with:
- port: Port number

Identifies which process is using the port

---

Workflow: Tmux Management

Step 1: List Sessions

Use tmux_list_sessions to see all sessions

Step 2: Create Session

Use tmux_create_session with:
- session_name: Descriptive name
- window_name: Initial window name

Step 3: Send Commands

Use tmux_send_keys with:
- session: Session name
- keys: Command to execute

Step 4: Capture Output

Use tmux_capture_pane with:
- session: Session name
- pane: Pane number

Common Signals

Signal	Number	Purpose
SIGTERM	15	Graceful termination
SIGKILL	9	Force kill
SIGHUP	1	Hangup/reload
SIGINT	2	Interrupt (Ctrl+C)
SIGSTOP	19	Pause process
SIGCONT	18	Resume process

---

Best Practices

✅ GOOD:

• Use SIGTERM before SIGKILL
• Check process tree before killing
• Name tmux sessions descriptively
• Use tmux for long-running tasks

❌ BAD:

• SIGKILL as first option
• Kill without investigation
• Leave orphan processes
• Unnamed tmux sessions

Checklist

• Process identified (PID/name)
• Resource usage checked
• Port conflicts resolved
• Graceful termination attempted
• Tmux sessions organized
