homebrew is a skill for Claude Code, Codex from G1Joshi/Agent-Skills. It costs 16 tokens per session (302 once invoked), scanned A, original, MIT.

A package manager for macOS and Linux that installs command-line tools and desktop applications. It can also record dependencies in a Brewfile so a machine setup can be repeated.

In plain words
What is it for?
Use it to install tools such as Node, Python, Git, Docker, and PostgreSQL, install macOS applications, and automate setup from a Brewfile.
Why use it?
It avoids downloading and configuring each development tool manually. A shared package list makes it easier to reproduce a developer workstation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

homebrew scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

What it actually says

Homebrew

Homebrew is the standard package manager for macOS. v4.2 (2025) is faster (JSON API) and supports declarative Brewfile.

When to Use

  • macOS Dev Setup: Installing Node, Python, Git, Docker, Postgres.
  • Casks: Installing GUI apps (VS Code, Slack, Chrome).
  • Dotfiles: Automating machine setup.

Quick Start

# Install wget
brew install wget

# Install VS Code (Cask)
brew install --cask visual-studio-code

Core Concepts

Formulae

CLI tools compiled from source (or bottles).

Casks

macOS native applications (drag-and-drop apps automation).

Brewfile

Dependency list. brew bundle installs everything listed.

Best Practices (2025)

Do:

  • Use Brewfile: Commit a Brewfile to your dotfiles repo. brew bundle dump generates it.
  • Cleanup: brew cleanup frees up GBs of old versions.
  • Pin versions: If you need stability, use brew pin postgresql@14.

Don't:

  • Don't run as sudo: Homebrew manages permissions.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
