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.
/plugin marketplace add trtmn/agent-pluginsnpx agentmods add plugins/trtmn/agent-plugins/homebrew-devgit clone --depth 1 https://github.com/trtmn/agent-pluginsGrade 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 yesterday.
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.
What it actually says
{
"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 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.
