Brew Update

Runs a full Homebrew maintenance cycle: update, upgrade outdated packages, and cleanup old caches.

Locating the script

Commands below use ${SKILL_DIR} for the folder that contains this skill. Set it to wherever the skill is installed, for example:

SKILL_DIR="$HOME/.claude/skills/brew-update"      # Claude Code
# SKILL_DIR="$HOME/.config/opencode/skills/brew-update"   # OpenCode / OpenWork
# On Claude Code you can also reuse the injected variable: SKILL_DIR="$CLAUDE_SKILL_DIR"

Quick Start

Run the helper script:

bash "${SKILL_DIR}/brew-update.sh"

What It Does

Update — Runs brew update to fetch the latest formulae
Upgrade — Upgrades all outdated packages (skipped if --no-upgrade flag is passed)
Cleanup — Removes old versions, downloads, and caches
Report — Prints a summary of what changed

Options

Flag	Effect
`--no-upgrade`	Only update and cleanup, skip upgrades
`--dry-run`	Show what would be upgraded without doing it
`--quiet`	Suppress verbose output

Example:

bash "${SKILL_DIR}/brew-update.sh" --dry-run

Notes

The script locates the brew binary via command -v brew, so it works with both /opt/homebrew (Apple Silicon), /usr/local (Intel), and custom HOMEBREW_PREFIX installs. If brew is not on PATH, set BREW before running: BREW=/path/to/brew bash "${SKILL_DIR}/brew-update.sh"
Logs are written to a logs/ directory next to the script
If a formula's post-install step fails (e.g. fontconfig), suggest running brew postinstall <formula>
