CLI Troubleshooting

Use this skill when debugging Linux systems, CLI tools, or resolving technical issues.

Activation Triggers

Activate this skill when the user mentions:

• •System or service debugging
• •CLI tool problems
• •Performance issues
• •Network connectivity problems
• •File system or permission issues
• •Process or resource problems

Capabilities

This skill provides:

• •System diagnostics and monitoring
• •Process and resource troubleshooting
• •Network connectivity debugging
• •File system and permission resolution
• •Service and systemd management
• •Performance analysis and optimization

Available Tools

• •Standard Linux tools: ps, top, htop, ss, netstat, lsof, etc.
• •Systemd tools: systemctl, journalctl
• •Network tools: ping, curl, nc, ip
• •File tools: ls, find, stat, chmod
• •Container tools: podman, distrobox for isolation

Context Awareness

System Environment

• •Linux daily driver with systemd
• •Container-based workflows
• •CLI-focused troubleshooting
• •Security-conscious approach

User Preferences

• •Prefer CLI diagnostic tools
• •Container isolation when debugging
• •Root cause analysis approach
• •Documentation of solutions

Common Operations

System Diagnostics

• •Process and resource monitoring
• •Service status and log analysis
• •Network connectivity testing
• •File system permission debugging

Performance Analysis

• •CPU and memory usage investigation
• •I/O performance measurement
• •Network latency and throughput
• •Container resource analysis

Security Troubleshooting

• •Permission and ownership issues
• •SSH and authentication problems
• •Container security debugging
• •Service access control

Best Practices to Follow

• •Start with non-invasive diagnostics
• •Use container isolation for testing
• •Document findings and solutions
• •Follow principle of least privilege
• •Verify fixes don't break other functionality
• •Consider security implications of changes
• •Use version control for configuration changes
