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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.00876 |
| Opus 5 | $0.00000 | $0.00438 |
| Sonnet 5 | $0.00000 | $0.00175 |
| Haiku 4.5 | $0.00000 | $0.00088 |
Grade E, and why
setup-mac scanned grade E with 3 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 2d 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.
Harvests environment variableshighData exfiltration
Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.
12. **Environment variables** — Check if a `.env` file exists in the repo root. If not, copy `.env.example` to `.env`, then ask the user which AI providers they want to use, collect the API keys, and update the `.env` fi Downloads and executes remote codehighSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mac Setup Action
When the user triggers this command, walk them through setting up their Mac for this repo. Run each step automatically. After each install command, verify it succeeded before moving on. Speak in plain, friendly language — assume the user has never used a terminal before.
Steps
-
Xcode Command Line Tools — Run
xcode-select -pto check. If missing, runxcode-select --installand tell the user a system dialog will appear — they should click "Install" and wait for it to finish before continuing. Pause and ask the user to confirm when the install is done. -
Homebrew — Run
brew --versionto check. If missing, install via:/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"After installing, ensure
brewis on the PATH (source the shellenv for Apple Silicon:eval "$(/opt/homebrew/bin/brew shellenv)"). -
nvm (Node Version Manager) — Run
nvm --versionto check. If missing, install via:curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bashThen source the shell profile so
nvmis available:source ~/.zshrc. -
Node.js — Run
node --versionto check. If missing, runnvm install --ltsto install the latest LTS version. -
pnpm — Run
pnpm --versionto check. If missing, runnpm install -g pnpm. -
Python 3 — Run
python3 --versionto check. If missing, runbrew install python. -
uv (Python package manager) — Run
uv --versionto check. If missing, runbrew install uv. -
tsx (TypeScript runner) — Already a devDependency, but verify global availability with
pnpm dlx tsx --versionor rely on the project-local install. -
Media / PDF tools — Optional (ask the user). Install these Homebrew packages if not already present:
imagemagickghostscriptffmpegRun:brew install imagemagick ghostscript ffmpeg
-
csvkit — Run
uv tool install csvkit(orpipx install csvkit) socsvkitandcsvsqlare available on the PATH.
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.

setup-mac is a command published in the GitHub repository maccman/growth-agents (5 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 876 tokens. A static security scan graded it E with 3 findings (harvests environment variables, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
