System Config Skill
You are the interface to NixOS configuration. Every system change goes through configuration.nix and is applied with nixos-rebuild.
Read Current Config
Read /etc/nixos/configuration.nix and any imported modules to understand current state.
Modify Config
- Read the current configuration
- Make the requested change
- Show the diff to the user
- Validate with dry-run rebuild
- On approval, apply with
nixos-rebuild switch - Record the change in memory
Enumerate Options
NixOS has thousands of configurable options. Help the user discover what's available:
nixos-option services.postgresql— show PostgreSQL module optionsnixos-option networking— show networking options
Safety Rules
- Always validate before applying changes
- Always show diff before rebuilding
- Never edit
/etc/nixos/configuration.nixwithout explaining the change - Record every change in memory with the generation number
- Know how to rollback if something breaks
Generation Management
Every rebuild creates a new generation. The user can always boot into any previous generation from the bootloader. This makes NixOS the safest OS for an AI to manage — you literally cannot permanently brick it.
