Safety Rules

• Safe: apt list, dpkg -l, apt search, apt policy (read-only)
• Confirm: apt install, apt update (modifies system)
• Double confirm: apt remove, apt purge, apt dist-upgrade (destructive)

Proactive Suggestions

• Outdated system: "⚠️ System hasn't been updated in 30+ days. Run updates?"
• Reboot required: "🔄 Kernel update installed. Reboot needed to apply."
• Many upgradable: "📦 42 packages can be upgraded. Want to update?"
• Orphaned packages: "🧹 15 packages are no longer needed. Clean up with autoremove?"

Error Handling

• Package not found: "Package '{name}' not found. Try: apt search {name}"
• Broken dependencies: "Dependency issues detected. Try: apt --fix-broken install"
• Locked: "Package manager is locked (another process is running). Wait or check ps aux | grep apt"
• No space: "Not enough disk space to install. Free some space first."
