A setup command for installing viban's required software and configuring its project workflow through questions. Dependencies are other programs the tool needs in order to run.

Preparing viban on macOS or Linux, checking for zsh, Python, gum, jq, and viban, and guiding project configuration.

It checks the operating system and existing tools, then identifies and installs missing requirements.

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.

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.

Model	Per session	Once invoked
Fable 5	$0.00010	$0.03523
Opus 5	$0.00005	$0.01761
Sonnet 5	$0.00002	$0.00705
Haiku 4.5	$0.00001	$0.00352

Security

Grade B, and why

setup scanned grade B with 2 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 3d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

/setup - Install Dependencies

Automatically install all viban dependencies based on the operating system.

Execution Steps

Step 1: Detect OS and Package Manager

# Detect OS
if [[ "$OSTYPE" == "darwin"* ]]; then
    OS="macos"
    PKG_MANAGER="brew"
elif [[ "$OSTYPE" == "linux-gnu"* ]]; then
    OS="linux"
    if command -v apt &> /dev/null; then
        PKG_MANAGER="apt"
    elif command -v dnf &> /dev/null; then
        PKG_MANAGER="dnf"
    elif command -v pacman &> /dev/null; then
        PKG_MANAGER="pacman"
    fi
fi

Report detected OS and package manager to user.

Step 2: Check Existing Dependencies

Check which dependencies are already installed:

command -v zsh &> /dev/null && echo "✓ zsh" || echo "✗ zsh"
command -v python3 &> /dev/null && echo "✓ python3" || echo "✗ python3"
command -v gum &> /dev/null && echo "✓ gum" || echo "✗ gum"
command -v jq &> /dev/null && echo "✓ jq" || echo "✗ jq"
command -v viban &> /dev/null && echo "✓ viban ($(viban --version 2>/dev/null || echo 'not installed'))" || echo "✗ viban"

Step 3: Install Missing Dependencies

For each missing dependency, run the appropriate install command:

macOS (Homebrew)

# Install Homebrew if not present
if ! command -v brew &> /dev/null; then
    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
fi

# Install dependencies
brew install zsh gum jq

Linux (apt - Debian/Ubuntu)

# Install zsh and jq
sudo apt update
sudo apt install -y zsh jq

# Install gum (requires Charm repo)
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://repo.charm.sh/apt/gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/charm.gpg
echo "deb [signed-by=/etc/apt/keyrings/charm.gpg] https://repo.charm.sh/apt/ * *" | sudo tee /etc/apt/sources.list.d/charm.list
sudo apt update
sudo apt install -y gum

Linux (dnf - Fedora/RHEL)

sudo dnf install -y zsh jq

# Install gum
echo '[charm]
name=Charm
baseurl=https://repo.charm.sh/yum/
enabled=1
gpgcheck=1
gpgkey=https://repo.charm.sh/yum/gpg.key' | sudo tee /etc/yum.repos.d/charm.repo
sudo dnf install -y gum

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 is a command published in the GitHub repository happy-nut/claude-plugin-viban (5 stars, last pushed 6mo ago), licensed MIT. It adds 10 tokens to every session and 3,523 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
