What problem does it solve? Claude lacks context about your personal machine setup — drive layouts, important paths, naming conventions, and installed software — so it gives generic advice that doesn't match your environment. This Skill interviews you and records that context in a persistent os-profile.md file that other skills can reference. ## Core Features & Use Cases - Structured Interview Workflow: Guides you through phased questions covering Windows 11, macOS, and Linux Ubuntu — drive/partition layout, important paths, and development tools. - Naming Convention Capture: Documents your folder, file, project, Git branch/commit, and environment variable naming styles using examples from a built-in reference guide. - Persistent Config Management: Stores your chosen save path in ~/.config/claude-utility/settings.json so the profile survives plugin updates, with support for changing the path later. - Use Case: You work across a Windows PC and a Mac Mini and want Claude to always know your projects live in D:\code on Windows and ~/Developer on macOS. Run the interview once, and the generated os-profile.md becomes shared context for other utility skills. ## Quick Start Run /utility:os-design and answer the interview questions to create your personal os-profile.md setup reference.
