Dotfiles validation checks for missing files, incorrect permissions, and syntax errors before installation. This Skill automatically runs pre-setup diagnostics, detecting common failures like broken symlinks, invalid Brewfile entries, and shell configuration issues, preventing deployment failures and saving hours of manual verification.

Yes, this Skill systematically executes and monitors your dotfiles setup script step-by-step, capturing errors and stopping on critical failures. It validates file existence, executable permissions, shebangs, symlink establishment, and shell loading—giving you immediate feedback for troubleshooting before committing changes.

This Skill detects missing files, incorrect file permissions, syntax errors, invalid Brewfile formats, broken symlinks, shell loading failures, missing aliases, crontab misconfigurations, and Claude Code settings symlink problems—covering the full setup validation and post-deployment verification cycle.

Post-setup verification confirms all symlinks are correctly established, shell configurations load without errors, and Homebrew packages are properly installed and resolvable. This Skill provides a detailed report documenting each verification step and guiding remediation if issues are found.

Yes, this Skill documents all setup progress, identifies where failures occur, and provides guidance for remediation and rollback steps. It validates required files, permissions, and syntax to pinpoint exactly what went wrong and how to fix it.

This Skill works with existing dotfiles repositories and setup scripts. It requires your dotfiles directory structure and setup executable to be present; it validates and tests them without modifying or creating the initial setup configuration.
