Is it safe to clean these developer caches?

Yes, the targeted caches generally contain re-downloadable assets like package binaries or build artifacts. The skill focuses on 'safe' cleanups where the primary cost of deletion is simply the time to re-download if needed later.

Does this skill require third-party tools like dust or ncdu?

While the skill can perform basic audits using native macOS 'df' and 'du' commands, it includes a reference guide and installation commands for enhanced tools like dust and dua-cli for a better user experience.

Which developer caches can this skill manage?

It provides specific cleanup commands for Homebrew, uv, pip, npm, Cargo, Rustup, Docker, Playwright, sccache, and Hugging Face model caches.

Does this skill delete files automatically without my consent?

No, the skill is designed to be interactive. It audits your disk usage and presents findings, using the AskUserQuestion tool to require your confirmation before any files are deleted or moved.

开发者工具

Optimizes macOS storage by auditing disk usage, pruning developer tool caches, and identifying large forgotten files.

Disk Hygiene is a specialized Claude Code skill designed to help macOS developers reclaim storage space and maintain a lean system environment. It automates the identification and cleanup of bloated developer caches from tools like Homebrew, Docker, npm, and uv, while providing a structured workflow for triaging the Downloads folder and locating large files that haven't been accessed in months. By integrating popular CLI tools like dust and dua-cli, it offers both high-level overviews and granular control over file deletion, ensuring developers can focus on coding rather than managing storage alerts.
