name: dotfiles-config description: Use when editing ANY configuration file in this dotfiles repository. Ensures files are edited in the repo (not symlinks), identifies correct file locations, and tracks the repository structure.

Dotfiles Config Skill

Golden Rule

ALWAYS edit files in ~/dev/dotfiles/, NEVER edit symlinked files in ~/ or ~/.config/.

The files in your home directory are symlinks pointing back to this repo. Verify with:

ls -la ~/.config/ghostty/config  # Should show symlink to dotfiles

Config File Locations

Package Management

CLI Tools (Nix Home Manager)

Edit: home/.config/home-manager/home.nix Apply: home-manager switch

GUI Apps (macOS Homebrew)

Edit: home-mac/Brewfile Apply: cd home-mac && brew bundle

Language Runtimes (mise)

Edit: home/.config/mise/config.toml Apply: mise install

macOS System Settings (nix-darwin)

Edit: mac/nix-darwin/flake.nix Apply: just nix-darwin-switch

Stow Commands

After adding new config files, re-run stow:

just stow-mac    # macOS
just stow-linux  # Linux
just stow-home   # Just base home/

Skills Location

Skills live in home/.claude/skills/ and are symlinked to ~/.claude/skills/.

To create a new skill:

1. Create directory: mkdir -p home/.claude/skills/skill-name
2. Create SKILL.md with frontmatter (name, description)
3. Stow will automatically symlink it

Common Mistakes to Avoid

1. Editing symlinked files - Always navigate to ~/dev/dotfiles/ first
2. Forgetting to stow - New files need just stow-* to create symlinks
3. Wrong platform directory - macOS GUI apps go in home-mac/, not home/
4. Editing ~/.config directly - These are symlinks, edit the source in dotfiles

Verification

Before declaring a config change complete:

1. Confirm you edited the file in ~/dev/dotfiles/
2. Check the symlink exists: ls -la ~/.config/<tool>/
3. Test the config works (reload app or run verification command)
