What is homebrew-dev?

A skill for packaging software and files so people can install them with Homebrew, the macOS package manager. It covers formulas for command-line tools and casks for apps, fonts, and other files.

Use it to create or update formulas and casks, package macOS apps or fonts, distribute prebuilt binaries, and publish Homebrew packages.

It helps turn software or downloadable files into Homebrew packages and manage their distribution through a personal tap or Homebrew's public repositories.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

homebrew-dev scanned grade A with 0 findings 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 1mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

{
  "name": "homebrew-dev",
  "version": "1.0.0",
  "description": "Package and distribute macOS apps, fonts, CLI tools, and arbitrary files using Homebrew formulas and casks. Use this skill whenever the user wants to create a Homebrew formula or cask, set up a personal tap, package a macOS .app bundle, distribute fonts or pre-built binaries via brew, use `brew create`, bump a formula or cask to a new version, submit a package to homebrew-core or homebrew-cask, or publish anything with Homebrew — even if they just ask how to \"make something installable with brew\", \"share my app through Homebrew\", \"update my formula\", or \"get my package into Homebrew\"."

What it installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 140 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
