CLAUDE.md#

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Repository Overview#

This is lassulus's personal NixOS/nix-darwin configuration repository, built on clan-core for managing multiple machines. It includes:

  • Multiple machine configurations in machines/
  • Configuration modules in 2configs/ and 3modules/
  • Custom packages in 5pkgs/
  • packages which could in theory be upstreamed to nixkgs should go into the pkgs folder, in the tools folder we add tools we write ourself which are more complex or not upstreamable

Key Architecture Components#

Machine Management#

  • Clan-core: Primary framework for managing multiple machines
  • Secrets: Uses password-store for secrets management via clan.core.vars

Network Overlays#

The repository manages multiple overlay networks:

  • Tor: Anonymous network access

Module System#

  • 2configs/: Main configuration modules
  • 2configs/default.nix: imported by all machines
  • 3modules/: Custom NixOS module definitions
  • Stockholm modules are also imported for krebs infrastructure

Common Development Commands#

# Enter development shell
nix develop

# Deploy to a specific machine
clan machines update <MACHINE_NAME>

# Format code
nix fmt

# Build NixOS configuration
nix build .#nixosConfigurations.<machine-name>.config.system.build.toplevel

# Build Darwin configuration
nix build .#darwinConfigurations.barnacle.system

# Deploy/rebuild Darwin configuration (for barnacle)
sudo darwin-rebuild switch --flake .#barnacle

# Access machines via SSH
ssh <machine-name>.r  # via retiolum
ssh <machine-name>.s  # via spora
ssh <machine-name>.n  # via nether
torify ssh $(pass show machines/<machine-name>/tor-hostname)  # via tor

Important: Git Staging for Flake Evaluation#

CRITICAL: New nix files must be staged (git add) before they are available in flake evaluation. When creating new packages, modules, or any nix files, always run git add <files> before testing with nix build, nix run, etc.

Git Push Policy#

CRITICAL: NEVER git push to any remote. Local commits are fine when asked. A push happens only when the user runs it themselves or explicitly says "push" for that specific change in the current conversation. This includes all remotes (origin, HTTPS via gh credentials, pair) and all branches.

Machine Facts and Secrets via vars#

  • SSH public keys
  • Network identities (retiolum, mycelium, zerotier)
  • Syncthing IDs
  • DKIM keys (for mail servers)

Secrets are managed via password-store and uploaded to /run/secrets on deployment.

Adding New Machines#

  1. Create directory machines/<name>/
  2. Add config.nix, physical.nix, and optionally disk.nix
  3. Generate facts using clan-cli
  4. Add to inventory in flake.nix
  5. Deploy using clan machines update <name>

Pre-Commit#

CRITICAL: Always run nix fmt before committing to ensure all files pass the treefmt formatting check in CI.

Commit Message Guidelines#

  • Use simple, descriptive commit messages without attribution footers
  • Use flake attribute paths as prefixes (e.g., tools.mutt: not just mutt:)
  • For flake.lock updates, use: "flake.lock: update"
  • Follow existing patterns seen in git log
