🛡️ Safety System

Commands are classified into four risk levels:

Level	Examples	Behaviour
✅ safe	ls, df, ps, grep	Confirm → execute
🟡 medium	rm file.txt, systemctl stop	Warn + explain + confirm
🟠 high	rm -rf ~/dir, curl … | bash	Warn prominently + explain + confirm
🔴 critical	rm -rf /, fork bomb, mkfs, dd wipe	Blocked — never executed

Patterns detected include:

• Recursive root deletion (rm -rf /)
• Disk format (mkfs)
• Disk wipe via dd
• Fork bomb :(){ :|:& };:
• Base64 obfuscated eval tricks
• Pipe-to-shell downloads (curl … | bash)
• System shutdown/reboot

---

⚙️ Configuration Reference

Config is stored in ~/.config/shellai/config.json.

Key	Default	Description
ollama_url	http://localhost:11434	Ollama API base URL
model	qwen2.5:7b	Default Ollama model
timeout	120	Seconds to wait for Ollama response
history_limit	500	Max entries kept in history
stream_explain	true	Stream tokens when explaining
confirm_safe	true	Ask confirmation for safe commands
max_retries	2	LLM retry attempts on bad output
