What problem does it solve? Local machine configuration drifts over time as installers, package managers, and manual edits change live files outside version control. This Skill keeps dotfiles, shell PATH, Brewfile, mise runtimes, and global agent configuration grounded in a single chezmoi source checkout and applies changes safely to live home files. ## Core Features & Use Cases - Chezmoi-managed dotfiles: Edit source files in the chezmoi checkout, review exact diffs, and apply narrow targets instead of broad repo-wide applies. - Config drift auditing: Run recursive status and diff checks on managed trees like ~/.agents and ~/.pi/agent, classify unmanaged installer files, and produce a structured drift report before any reconciliation. - Package and runtime management: Keep Homebrew packages in the Brewfile template and Node runtimes plus global npm CLIs in mise config, with fresh-shell verification after changes. - Use Case: After running an installer that added new skill files, ask the agent to audit config drift; it inventories unmanaged paths, secret-scans candidates, and reports what to accept, declare, or exclude before touching source. ## Quick Start Use the config-manager skill to audit config drift across my dotfiles and agent configuration, then report what changed without applying anything.
