Default Blocked Command Patterns

By default, PicoClaw blocks the following dangerous commands:

• Delete commands: rm -rf, del /f/q, rmdir /s
• Disk operations: format, mkfs, diskpart, dd if=, writing to /dev/sd*
• System operations: shutdown, reboot, poweroff
• Command substitution: $(), ${}, backticks
• Pipe to shell: | sh, | bash
• Privilege escalation: sudo, chmod, chown
• Process control: pkill, killall, kill -9
• Remote operations: curl | sh, wget | sh, ssh
• Package management: apt, yum, dnf, npm install -g, pip install --user
• Containers: docker run, docker exec
• Git: git push, git force
• Other: eval, source *.sh
