+### Chezmoi Sync
+When making changes to dotfiles (including Claude files in `~/.claude/`), always:
+1. Sync with chezmoi:
+   - `chezmoi add <file>` for new files
+   - `chezmoi re-add <file>` for updated files
+2. Commit the changes in the chezmoi source directory:
+   - `cd $(chezmoi source-path) && git add -A && git commit -m "<descriptive message>"`
