# MielinOS CLI - Debugging Operations Examples
# This file demonstrates agent debugging workflows

# 1. Attach debugger to agent
echo "=== Attach debugger ==="
mielinctl debug attach agent-001
# Alias: mielinctl debug connect agent-001

# Attach with custom port
mielinctl debug attach agent-001 --port 9229

# 2. Trace agent execution
echo -e "\n=== Trace execution ==="
mielinctl debug trace agent-001 --duration 30
# Alias: mielinctl debug track agent-001 --duration 30

# Trace with output file
mielinctl debug trace agent-001 --duration 60 --file trace-output.json

# 3. Dump agent state
echo -e "\n=== Dump agent state ==="
mielinctl debug dump agent-001
# Alias: mielinctl debug snapshot agent-001

# Dump with memory details
mielinctl debug dump agent-001 --memory

# 4. Show profiling data
echo -e "\n=== Show profiling data ==="
mielinctl debug profile agent-001
# Alias: mielinctl debug perf agent-001

# Profile CPU usage
mielinctl debug profile agent-001 --cpu

# Profile memory usage
mielinctl debug profile agent-001 --mem

# Profile both
mielinctl debug profile agent-001 --cpu --mem

# 5. Complete debugging workflow
echo -e "\n=== Complete debugging workflow ==="

# 8. Remote debugging setup
echo -e "\n=== Remote debugging setup ==="

# Attach debugger and get connection URL

# 9. Debugging with different output formats
echo -e "\n=== Different output formats ==="
mielinctl debug profile agent-001 --output json
mielinctl debug profile agent-001 --output yaml
mielinctl debug profile agent-001 --output table
