What This Skill Does
Audits a Homebrew installation on macOS for outdated packages, unused downloads, and configuration issues. Runs a single script combining brew outdated, cleanup dry-run, and brew doctor checks. Outputs a summary of total formulae and cask counts.
Combines outdated listing, cleanup estimates, and brew doctor diagnostics into one command instead of running three separate brew commands and interpreting their output manually.
When to use it
- Finding which packages need updates before a macOS upgrade
- Estimating disk space recoverable from old Homebrew downloads
- Diagnosing broken symlinks or permission errors after a system update
- Checking cask versions after returning to a development machine
- Running a monthly maintenance check on installed formulae and casks
Example Workflow
Here's how your AI assistant might use this skill in practice.
User asks: Are any of my Homebrew packages outdated, and how much disk space can I free up?
- 1Runs brew-audit.sh to collect outdated formulae and casks with current and available version info
- 2Checks cleanup opportunities and calculates estimated reclaimable disk space
- 3Runs brew doctor to surface permission issues, broken symlinks, or orphaned kegs
- 4Compiles a summary with total formulae count, cask count, and Homebrew prefix
A structured report listing outdated packages, estimated reclaimable disk space, and any health warnings from brew doctor
